What you should know about monitoring NDVI in agriculture

Monitoring agricultural fields tracking progress, and spotting problems in the field before symptoms are apparent is crucial for a successful harvest. Exciting advancements in technology allow us to capture images of farms worldwide with the aid of satellites, thus making monitoring simple and affordable. The most popular vegetation index used by farmers is the Normalized Difference Vegetation Index(NDVI); monitoring NDVI in agriculture can serve as an indicator of the health of plants.

What is NDVI, and why is it useful?

NDVI is a remote sensing method for estimating crop health and biomass. The NDVI index measures the difference between visible and near-infrared reflectance of the vegetation. Crop reflectance depends on leaf area, chlorophyll content, age of leaves, canopy density, and soil type. NDVI is often used with satellite imagery, which provides high-resolution images from space. The use of satellites has helped to make NDVI more accessible to farmers worldwide because it is accessible to anyone with an internet connection. Monitoring NDVI in agriculture for crop health screening has been around for decades. Still, it has only recently gained popularity due to the use of satellites and high-resolution aerial photography that provide frequent revisits. It gives an accurate estimate of plant biomass and leaf area index (LAI) without needing any ground data collection or manual interpretation.

How is NDVI calculated?

NDVI is calculated with the following formula: 

NDVI = (NIR-Red) / (NIR+Red)

Where NIR is near-infrared light and Red is the visible red light. NDVI values range from -1 to 1. Areas of sand, rock, or snow show values of 0.1 or less. Sparse vegetation such as senescing crops shows moderate NDVI values of between 0.2 to 0.5. High NDVI values of 0.6 to 0.9 correspond to dense vegetation.

How can I start monitoring the NDVI of my fields?

Monitoring fields becomes very simple, and it does not require prior knowledge. Apps like Agrio allow you to draw your fields on the map to start the monitoring process. Once the fields’ location is defined, you will receive frequent scans and interpretations.

How to analyze NDVI imagery?

By inspecting the NDVI scans, we can better understand the fields’ situation and spot places that might show stress. For example, examine the level of green in the image below, showing different stages of plant development in the various fields, and internal variation inside individual fields.

Notice the isolated green patches in the otherwise orange reading that indicates the development of weeds growth.

When comparing the NDVI scans of consecutive days, we can see spots that do not develop as expected and require immediate attention. For example, examine the image below and notice the red patches in fields that are in early development stages and therefore are expected to show an increase in the NDVI with time.

The limitations of NDVI in agriculture

NDVI shows a low correlation with the chlorophyll content; it is more severe in advanced growth stages when the NDVI becomes saturated. This saturation is due to the increase in the leaf area and the density of the canopy structure. Therefore, in this stage, there is a need to monitor an index that is highly correlated with the leaf chlorophyll content and less sensitive to the leaf and canopy structure.

Chlorophyll plays a crucial role in photosynthetic processes such as light-harvesting; thus, the content of chlorophyll is a potential indicator of a range of stresses. Other spectral bands can detect chlorophyll functioning changes, such as the red-edge early on. This precedes the actual losses in leaf chlorophyll concentrations; therefore, monitoring such changes can be an early indicator for developing biotic and abiotic stress.

Why technology progress makes the selection of specific vegetation indices less critical?

Since we have become very skilled in teaching computers to identify patterns in a large amount of data, selecting a specific index is not essential. Instead, artificial intelligence can analyze the entire spectrum of reflected light and provide insights. In the old days, pre-engineered features were needed to train machines to classify patterns in the data. But these days are over, and we now know how to program the machine to pick the best features during the training process.

Vegetation indices are convenient when human experts are examining the scans. It is difficult for humans to make sense of a large amount of information encoded in the full spectrum. For that purpose, it is still useful to present specific indices that experts are familiar with. But the number of monitored acres and the high frequency of satellite revisits make it less desirable for growers and agronomists to do the analysis manually.

What started as a choice due to limitations became a convention in the industry.

Leveraging artificial intelligence to detect anomalies in satellite imagery

After discussing the benefits that can result from monitoring spectral reflectance, we need to deal with the question of the practicality of this approach. One of the challenges in leveraging spectral analysis in stress detection is to identify the precise patterns in the satellite scans that indicate that the plants are under stress. Even when individuals develop the expertise of examining the scans manually, the task becomes cumbersome when the number of acres that are covered is high.

The use of artificial intelligence in agriculture has been on the rise due to the recent advancements in technology and contributes to the efforts to overcome these challenges. Anomalies are detected using artificial intelligence by making decisions that are based on patterns that were learned from large training datasets.

The entire spectrum of light that can be captured by satellite sensors contains interesting information when it comes to early stress detection.
The entire spectrum of light that can be captured by satellite sensors contains interesting information when it comes to early stress detection.

The progress in the development of early detection tools can become faster once a large volume of high-quality data can be collected in an affordable way. To achieve that, we took the crowdsourcing approach and built a tool that allows growers to identify plant pathology based on smartphone-captured images. Growers are directly benefiting from this service while helping to train algorithms for early detection, a capability that can be more beneficial for them in the long term. The geotagged images are used as ground truth and help us to train the algorithms to identify the problems directly from the satellite scan. The computer is presented with satellite scans in which it is known which of the field regions are diseased. We make fast progress as we can collect a large volume of high-quality data.

Such data allow us to learn the patterns of the typical reflectance patterns of a large number of different plant problems. We leverage these capabilities to develop easy-to-use monitoring solutions. Farmers using Agrio can monitor the health of their fields in a very simple way. All that is needed is to define the field location by drawing a polygon representing the field boundary. Once this is done, we are kicking in to do constant monitoring for you and notify you when a new scan is available.


Satellite monitoring in agriculture is a technique that has been used for many years. However, the use of satellite technology to monitor agricultural fields has increased significantly over the past decade. Using satellite monitoring in agriculture can increase yield, improve precision, and early detection of issues with crops.

On our platform, users can get access to Sentinel and PlanetScope satellite scans. We apply our algorithm to the imagery to monitor crop progress, spot problems in the field, and alert growers when interventions are needed.

We invite you to leverage these capabilities to avoid losses, grow better, and spray less.


How to prevent plant fungal diseases

Experiencing poor crop yields due to plant fungal diseases such as downy mildew, rose black spots, or rust? Do not see this as a necessity of reality. Plant fungal diseases are becoming more and more prevalent as the climate changes. They cause significant economic losses and are challenging to deal with, but with the right approach, remarkable results can be achieved.

Did you find yourself again in the situation in which the plants show symptoms? You probably ask yourself what this disease is and how I should treat it. Unfortunately, many growers stop there. However, the most critical question to ask should be – how should I prevent it from happening next time.

In the ideal situation, growers should be able to apply fungicides before the disease starts to develop in the field. You might be tempted to spray when there is a slight doubt. However, excessive spraying is not economical and can cause unnecessary damage to plants. We have limited opportunities to apply preventative measures, so it’s better to be at the optimal time.

One condition that should be met before a decision to spray is made is the presence of spores in the field. However, the presence of the fungal spores on plants is not enough; the disease develops only when the weather conditions support that. 

Farmers find it difficult to monitor these conditions as it requires knowledge about the environmental conditions that can not be easily obtained. But fungicides applied when spores are not in the field or when weather conditions are not suitable for the disease development get wasted. In addition, such applications increase the risk of pesticide injury to the plants, are bad for the environment and growers’ health, and reduce the potential profits at the end of the season.

So how can you decide when it is time to spray? Let us dive a bit into the technicalities. By the end of this short article, you should be informed on how to time the preventative applications correctly.

How do plant fungal diseases develop?

Fungal spores are the first stage in the fungal life cycle and the mean by which fugal diseases spread. Their mobility helps them travel by riding other organisms or by traveling long distances carried by the wind. Once they land in a supportive environment, the spores germinate and form a mycelium. The mycelium provides nutrients to the spores and supports their growth.

As the mycelium grows, it may encounter another compatible fungus. The fungi cells merge into a single cell and then split into two cells, which results in mixed genetic information. This sexual reproduction ensures genetic diversity.

In some environmental conditions, most fungi can reproduce asexually. When it’s time to reproduce, instead of branching out and combining with another mycelium, they produce mitospores (Asexual spores) that look just like the parent. These then start a new cycle and grow a new mycelium.

Germination and reproduction of the spores initiate the disease. Pathogenic fungi can live inside plants or on their surfaces. They feed on the plant tissue and damage it.

In the stage where the spores were not germinated and infection was not started, protectants fungicides can be applied. Protectants can be used in healthy plants to prevent spores from growing or penetrating the host tissue. Some examples of protectants are mancozeb, chlorothalonil, and copper-based fungicides. After the disease is initiated, other fungicides should be applied to eradicate the fungi. These fungicides should have a different mechanism of action that disturb other processes that allow the fungus to develop and survive. Therefore, it is important to alternate between different fungicides. Utilizing different mechanisms of action help to prevent resistance development.

Spore traps can provide early warning of the spread of plant fungal diseases

How can you know if the spores were carried with the wind and arrived in your region? The direct way is to install spores traps in the fields. Agricultural spore traps are used to detect the presence of fungal spores in the air. They help farmers to take preventive measures against plant fungal diseases. Farmers should install the traps in good distribution in fields and send the air samples from the traps to the lab at a high enough frequency. The lab does a microscope analysis to quantify the spores and classify them.

The trap costs, maintenance overhead, and the need to send frequent samples to the labs might make it a non-practical practice. There are attempts to bring costs down and do the analysis in the field, but in the near future, growers might want to consider alternative approaches.

How can we learn about spores spread without installing expensive hardware?

Considering the obstacles that were discussed above, we can think of other ways to monitor the spread of spores. Plants can be thought of as spore traps, in the fields and around them. Gardens are excellent examples of places in which fungal diseases can get discovered first.

When spores land on plants and disease develops, the symptoms make it possible to identify the exact pathogen and save the need to do the lab testing. The region in which the disease is initiated is going to benefit less from the early warning but the fields around can. But actually, we can do better than that by modeling long-distance spread.

How far from the hot spot can such an observation be used as a warning? Once an area with an infestation is discovered, weather-based models can be used to predict the routes of spread of the spores by analyzing the wind direction and speed. By combining such predictions with actual observations on the ground, as the migration progresses, we can have a good understanding of the spores spread in real-time.

What are the weather conditions that support fungal disease development?

Weather variables such as temperature, humidity, and rainfall can help model the risk of spores germination and reproduction. When the optimal conditions persist for several uninterrupted hours during the day, the disease initiation is expected to happen. Each fungus should be modeled differently. Scientists arrive at such models by experimenting with the environmental conditions in a controlled environment. Growers and crop advisors can utilize such models to track the development of the fungi of interest in their fields.

With the ability to track the weather constantly and apply such models, an early warning system became possible. As discussed above, if the weather conditions are suitable but the spores are not present, an alert will cause unnecessary fungicide application. Therefore it is essential to wait for these two conditions to be met. With the aid of technology, and the ability to collect data globally, we managed to bring the predictive capabilities of this approach to an all-new level, and we made it easily accessible for you.


By considering the presence of the spores in remote areas, the wind variables, the presence of potential hosts in the route between your fields and the monitored remote regions, and the risk of spores germination and reproducing; we can provide an accurate map of the risks of many diseases across the globe. By using this approach, we can optimize the decision-making in fungicide applications without the need to install expensive hardware in fields. In Agrio we built a large community of farmers and gardeners that are monitoring their crops. The information that is being uploaded to the system, together with the identification of the plant problems, help us to see the big picture. We invite you to take advantage of this progress and increase your planning capabilities for better plant protection.


App to identify plant diseases and pests

Visual inspection is an important aspect when it comes to plants’ health. As lab test is not a practical tool for a day-to-day diagnosis, due to costs and turnover time, growers are making decisions based on the symptoms that can be seen on plants. Plant inspection is time-consuming, and it often leaves growers with doubts. Crop advisors are there to support the growers with their decisions and make sure that errors are minimized. But what if such assistance is not available? Luckily technology can come to the rescue. An artificial intelligence-based app to identify plant diseases became possible thanks to the big leap in performance achieved by the artificial intelligence research community. We offer a plant diagnosis app to help growers solve their plant problems with ease.

In recent years, software-based products can complete vision-based tasks with above human expert accuracy. Why not apply this technology to agronomy advisory then? The widespread of mobile devices makes this question even more relevant as such devices made it possible to distribute a plant diagnosis app on a large scale. Farmers and home growers can carry an agronomist in their pocket when inspecting their plants.

Agrio is an Android and iOS application developed to do just that. It helps growers to manage plant protection in a better way. Disease identification is a crucial component in the plant protection routine. The value that the app is offering attracts other audiences as well. Home growers seeking professional advice are a large part of the user base, leveraging the disease identification feature for their needs. This is aligned with a growing trend of millennials that use technology to help grow food in their homes. In addition, Agrio suggests biological and organic treatments as part of the integrated pest management protocols, making it even more relevant for gardeners and home growers. Did you notice tomato leaves curling in your garden and are you curious to know what is the cause? Our app can figure it out once it sees the image of the symptoms.

A plant diagnosis app that saves time

During crop scouting, instant identification saves the need to waste time on identifying the problems and recording the results. Moreover, the recorded images can be inspected by others and used as a reference in the future. Growers that find it difficult to obtain accurate diagnosis use the tool as an assistant or as a way to receive a second opinion when there are doubts. This is especially important when other sources of advice are unavailable, such as in countries in which the ratio of the number of growers to agronomists is very high.

Why is it important to identify the cause of the problem in a precise way?

Every pathogen or insect will require a different treatment. In addition, pathogens can develop resistance to some treatments in some geographics; this information should be considered when treatment is advised.

When the problems are already observed in the plot, exact identification can help prevent spread. The strategy on which measures should be applied depends on the precise identification of the cause.

When it comes to prevention, growers should consider the implications for the following seasons. Crop rotation or soil treatment might be advised when the pest is expected to survive in the soil or plant debris. In the case of a viral disease, it might be advised to plant virus-resistant varieties in the following seasons once the virus has been identified in the region. Other factors that require soil preparation before planting are saline soil, wrong soil pH, nematodes, and more. In all the examples above, exact identification of the problem must be obtained to prevent future losses.

How artificial intelligence identifies plant diseases?

State-of-the-art in image recognition is based on the concept of artificial neural networks. Like how agronomy students learn, the neural network is presented with examples of diseased plants that were tagged by experts. In the learning process, the network of neurons adapts until it maximizes the performance score. The result is an app that identifies plant diseases and constantly improves as more examples are presented. Based on the growers’ feedback and observations done in the fields, Agrio learns which treatment protocols are more effective. A treatment that was not effective signals a possible problem with the identification and provides more input for the network to improve.

Symptoms of different diseases might seem similar, how Agrio can tell the difference?

The symptoms seen on the different plant parts and information on the geography and weather help us differentiate between problems. Similar to the process of medical diagnosis, the app will present questions to the growers that help arrive at the correct diagnosis in case the information in the images is insufficient.

Why satellites and other remote sensing devices are not enough when it comes to the exact diagnosis of plant problems?

Remote sensing is helpful when growers want to pinpoint the exact locations where problems started. But cameras mounted on drones or other machinery will see just a subset of the symptoms. Often, the symptoms seen on the foliage are secondary; the problem can be with the internal tissues in the stems or roots. The app instructs the grower on what interventions are needed to expose the root cause. In this sense, there is no good alternative yet to boots on the ground.

Can Agrio learn to identify plant diseases it didn’t see before?

The app is constantly learning. When users upload images that cannot be identified by artificial intelligence, there is an option to share the photos with human experts. The correspondence between the grower and experts is used by artificial intelligence to learn. As a result, Agrio can apply previous skills to master new plants faster.

What did Agrio learn to identify so far?

Diseases and insect pests are the majority of problems we deal with. But many other abiotic stressors were learned, such as nutrient deficiencies, toxicities, environmental factors such as wind and hail, and many more. The ability to distinguish between biotic and abiotic stress is important and can save unrequired pesticide applications.

What are the uses of such technology in the futuristic farm?

In the future, computer vision technology will be essential in autonomous farms. In such setups, automatic disease identification will be crucial.


Agrio is an app that identifies plant diseases and serves as a personal agronomist that can be carried in the pocket. We make a ground-breaking plant protection support system available to any grower with a smartphone. Join us today and take part in this exciting journey.


An Albanian agricultural development expert shares his thoughts on precision agriculture

We met Aurel Grabocka in 2020 when he expressed interest in Agrio and got inspired by his enthusiasm for making agriculture better. We had wonderful conversations with him in which we learned about the agriculture scene in Albania and his ideas on how to improve it. We invited him to share his experience with precision agriculture, challenges, and his hopes for the future.

Tell us a bit about yourself, and your experience with agriculture. What kind of services do you provide to growers?

I have a master’s degree as an advisor and trainer for small and medium-sized enterprises (SMEs).

In 1998 I founded the Regional Development Agency (SME) of Korce, Albania. I am the founder and CEO of RDA Korca since then. It is an NGO.

Mainly, RDA Korca is known as a consulting agency for SMEs and local governments and is a leader in the development of business plans and feasibility studies for SMEs. It has been also a supporter of startups in the region.

Since 2019, supported by two EU projects, we have developed and are working on smart agriculture and regenerative agriculture. Especially we are developing extension agriculture services based on Agriculture 4.0. 

Korca region is one of the most important producers of apples in Albania and we are working to support apple producers in producing high-quality apples. Through smart agriculture applications like Agrio, we support them to use inputs in a smart way and minimize the use of pesticides and insecticides. At the same time, we are cooperating with innovative agronomists to change the nutrition of the orchards and increase their immunity. 

The Objective is to enhance Korca’s farmers by increasing the quality competition of Korca’s apples.

How many people work with you? What is their responsibility?

We are a small team of three full-time people. Their responsibility is to train farmers on how to use smart applications like Agrio and team with them to improve the production on their orchards.

The Agronomist supports them in improving the nutrition of the orchards based on the data from weather stations, disease models, smart agriculture applications, and SAP analyzes. 

We hire experts based on the requests and needs of our farmers.

Tell us about the disease and pest challenges? How did you manage plant protection in your fields in the past?

Apple orchards suffer from a lot of diseases and insects. In the past farmers managed plant protection based on assumptions and by cooperating with each other. They were spraying based on their experience and having the same calendar every year. As a result, the use of pesticides and insecticides has been increasing every year.

In the last two years, we have introduced disease models based on data from the weather stations. At the same time, we are introducing Agrio as an application that supports farmers in their decisions to protect their crops from insects and pests. 

Our main approach is to support farmers through Agrio and regenerative agriculture practices based on SAP analyses. The route to take samples for SAP analyses is based on the indicators and indices offered by Agrio.

How did you come across Agrio?

Agrio has been suggested to us by a German expert that visited our farms. He suggested this application as a great tool to improve the protection of the orchards from pests and insects. After using it for some days I had an online meeting with Mr. Nessi Benishti who is the CEO of Agrio. Since then we have increased the cooperation, testing, and working with the tool. We are looking to go even deeper into this cooperation.

Recently, we have started to create Teams to support farmers through the platform. It is very interesting and helpful. Farmers find many beneficial services just by using their smartphones.

A seminar on disease and pest identification in apple trees

What is your perspective on digital solutions in agriculture? What do you wish to see in the future?

We are looking to increase the cooperation with Agrio and at the same time develop the network of farmers. Agrio has a great option of teamwork and cooperating with the farmers and experts on the same platform. At the same time, we can have the support of Agrio experts that support us very fast and with great quality advice.

We are looking to cover all of Albania with our extension services. In the near future, we will have a call to ask experts to join us through the platform and to support farmers with advice.

How the satellite scanning changes the way you understand the orchards’ situation? 

Agrio offers a lot of functions to check the health of the orchards by scanning with satellites. It is easy to compare the images of the satellites, check on graphs how the vegetation is doing, and develop the crop scouting route to visit the areas which represent a decrease in the indicators. It offers the possibility to cooperate with the team, exchange ideas and notes, and check the quality of the work.

Through the satellite images, the farmer knows exactly the location where to check and find out in advance if something is wrong with his crops.

Can you describe a particular case in which Agrio helped you detect a pest or a disease? How is the app helping you with your work? 

Agrio team assists us without request on areas that show a decrease in the indicators. They send to us the location and with the help of the smartphone GPS location, we go to the exact location and check for the problems. In this case, after we send the pictures related to the problems, first there were doubts about nematodes on the roots. After digging and discovering the roots, we have seen that there were no signs of nematodes. So, we continued to check the tree and we found prionus apple root borer. After showing through pictures of the stem borer and after the experts of Agrio helped us to identify it, we received their suggestions for the treatment. After applying the treatment, we saw that the vegetation indicators for this field are increasing, and the trees are doing very well.

Precision agriculture applied to early disease and pest detection in the orchard
Detection of pest infestation in an orchard with the aid of satellite imagery

What is the dynamic in the community of growers in your region? What is the level of interest in precision agriculture solutions? 

We have more than two years of promoting precision agriculture and testing it. It is moving and growing but still, it is slow and difficult. Farmers have a lot of difficulties and lack the resources and knowledge to apply precise agriculture. 

What do you wish for in the future?

We wish to increase the community of farmers that use precise agriculture and improve the quality of their products. We want to decrease the use of pesticides and insecticides and provide healthy food for people. We wish to regenerate soil on our farms and produce dense crops and fruits full of vitamins and proteins.

Anything else that you would like to add?

We are changing the existing agriculture practices and we hope that farmers will change on a great scale. 

Public institutions, local governments, and universities need to support and develop smart agriculture to change the existing theories and practices. Especially public servants and academia of agriculture departments in the universities must increase their knowledge of precision agriculture and start moving from conventional agriculture to regenerative agriculture.


A guava grower from Hyderabad shares his experience with precision plant protection

We met Syed Abdulla in 2021 when he just joined our platform. Syed is a guava grower from Hyderabad, Telangana, India. He represents a promising phenomenon of young professionals who bring technology to the farm to help shape the future of agriculture. We invited him to discuss plant protection, and share his experience, challenges, and his hopes for the future.

Hello Syed, please tell us a bit about yourself, and your orchard history. Why did you choose to grow guava?

I am a medical student, my father was a sales manager, and my brother is a computer science graduate. 

My grandfather used to grow sugarcane then shifted to rice, my father continued to grow rice for several years. These were not very profitable, then we gave the land for lease for a few years, they grew cotton in that period, then in 2018 we planted guava, coconut, and lemon. 

The choice of planting guava was not just about earning money but providing products that would meet the nutritional needs of the body, guava contains vitamin C, iron, and calcium. These minerals and vitamins are part of the majority of medical supplements. We chose Taiwan guava because it has a good shelf life. On a tree as well as post-harvest. 

How many people work with you? What is their responsibility?

My teammates are my father and brother, they monitor field works and see that irrigation and fertigation are provided on time.l live in the city to pursue my studies, I monitor the farm through satellite scans according to the scans I plan my visit to the orchard, I come and inspect the trees and I also deal with fertigation and its plan. 

There are 4 resident workers who deal with the daily inspection of the orchard, keeping it clean and spraying insecticides and providing irrigation and fertigation, and harvesting. 

There is an additional team of 10 workers who come to work when the workload increases. During harvesting for example.

Plant protection made simpler with the aid of remote sensing

Tell us about the disease and pest challenges? How did you manage the plant protection in your orchard in the past?

In guava the major destructive pest is the fruit fly, which can cause 100% fruit damage, fruit borers can also cause significant damage if spraying is not applied during the fruit set. Mealybug is a minor pest, it can be easily controlled if the fruit is not bagged, but when bagging is done, if the bag is not tightened to twig properly, it can cause severe infestations if the periodic sprays are not done, the major problem with the mealybug is its hiding capability and the waxy layer on the adults which gives them protection. Other foliar pests can be easily controlled by contact and systematic insecticide until they are susceptible to available insecticides. Then comes fungal diseases, it is very challenging to control fungi up to 100%, and this causes the development of fungal diseases that damage fruits during heavy rains. During such periods the fungi spread rapidly to other fruits. 

Nematodes can cause severe retardation of growth in the summer. 

After getting versed with all pests and diseases if one can bring fruit damage down to 5% to 10% then that is a great achievement. In the beginning, if you start managing without taking advice from experts and experienced farmers then you will face huge losses, that’s the reason I want to share my journey to help farmers avoid the mistakes which I did. 

In the past, we experienced massive rains during the harvest period which led to huge fruit fly infestation and 100% loss.

In another season,  a representative of a pesticide company made weekly visits to the orchard and suggested solutions for problems. He promised that he will give results without bagging, but we didn’t want to take the risk, so we bagged 75% of the fruits and left 25% unbagged, but after 50% of harvest the first spell of rain caused fruit fly infestation on unbagged fruits and the second spell of rainfall lasting for 15 days causing the development of fungus in bagged fruits leading to 50% damage.

As a biology student, I am curious about pests, plants, and diseases and I gained most of my knowledge regarding them till the end of the third season. We managed to maintain plant protection based on this knowledge and then I came across Agrio. 

How did you come across Agrio?

One day I thought I am not the only one who is doing agriculture. There are lakhs of people around the world who are dealing with these challenges, so I started searching for platforms where I will get access to the best agriculture experts. I was searching for platforms in the play store, and this is how I came across Agrio. 

What is your perspective on digital solutions in agriculture? What do you wish to see in the future?

Digital solutions can make a huge positive impact in the agriculture sector but can’t eliminate physical inspection, they make things easier, less time-consuming, and can make agriculture a part-time business and a more profitable business. 

Regarding Agrio, I want to see the expansion of the pest modeling. I am using the daily briefing feature which keeps updating the stage of pest and status of pest infestation so that spraying can be done during a period during which the pest is susceptible to pesticides. I wish to have the daily briefing feature for all pests that I deal with. 

Agrio should conduct research on new methods of pest controls and communicate it with the users in the form of tutorials. 

We live in an era of technological progress. Continuous research helps you find new methods of controlling pests that save time and money, reduce insecticide exposure to fruits and improve results. 

How the satellite scanning changes the way you understand the orchard situation and practice plant protection? 

Satellite scans decreased the load of inspection and they help in eliminating many differential diagnoses and narrowing down suspected causes, they help in understanding which part of the orchard is growing during a specific period. They indicate nutrient deficiency by showing homogenous fall when fertigation is delayed. They allow to demarcate the hotspot zones and monitor them periodically. They also allow the detection of the origin of pest infestation. 

I think that a satellite scan is a non-specific modality, a satellite scan followed by inspection helps to make out what the problem is. I hope to see the progress that can make satellite scans more specific in the future. 

But in spite of its limitations it helps a lot in understanding the orchard situation, it helps farmers to divide orchards into pest zones and non-pest zones and make a spray in pest zones, and it helps to detect differential growth of trees in different areas and detect defects in areas with low growth. 

Can you describe a particular case in which Agrio helped you detect a pest or a disease and protect your plants? 

Nematode infestation was detected on a few plants through satellite scan that showed a decline in that area, then photos of plants in that area were uploaded with the smartphone camera by us, then inspection of the roots was suggested, nodules were detected on roots, and nematode infestation was identified. 

The satellite scan help to localize areas where mealybug is present on leaves of plants based on differential decline shown by infested area, so that geotagged photos can be taken in that area and the pest zone can be demarcated then spraying can be done in that area, this reduces the amount of exposure of plants to pesticides as spraying will be done only in an infested area, this also reduces the cost of spraying. 

Does the app help you with coordinating the operations on the farm? Please describe how it works.

The app has excellent features that can help teammates to coordinate and get work done perfectly. It has a feature of taking geotagged photos, an inspector can take photos in places of infestation so that teammates can make sure treatment is done there and can monitor its progress. It has a chat where daily work can be communicated. This helps in coordinating irrespective of different working hours. The feature of the intervention calendar helps in maintaining records of it and the information is accessible to all teammates. Sometimes you get excellent results but you forget the things that were done and the pesticides that were used. The satellite scans and intervention helps to recall and review the results of interventions. 

What is the dynamic in the community of growers in your region? What is the level of interest in precision agriculture solutions? Do you see how area-wide integrated pest management can be applied with the aid of technology to the benefit of the whole community?

Most of the guava growers here grow native variety which has a short shelf life on trees as well as post-harvest. Bagging is not economical so they frequently suffer from fruit fly losses. Most of the Taiwan guava growers are 500 km away from here, they are also bagging fruits to produce first-quality fruit as suggested by local experts. In other crops, the majority of farmers are uneducated and depend on plant protection advice from either pesticide shop owners or the horticulture department. 

Area-wide management can help to detect pests at an early stage when the population is low, this reduces the spraying of pesticides in adjacent fields, and many of the infestations can be prevented.  An individual farmer will suffer many challenges, but communication and cooperation between farmers of an area can make huge changes and provide profitable crops. 

Who are your produce buyers? Tell us about your marketing challenges. What do you wish for in the future?

Brokers in the main market of Hyderabad buy our produce, today due to the pandemic many countries are in debt, and people’s economic situation is worsening. Due to this buying fruits became secondary to low class and lower middle class, which led to a decrease in demand and a fall in prices. 

Due to urbanization many big markets of the city are getting shifted to the outskirts, and there is an increase in the travel costs of the city vendors to the market, so many workers are finding it difficult to carry this profession, these are leading to a decrease in consumption and further fall of prices. 

Regional markets should be established within the city according to the consumption and supply should be made accordingly to decrease cost price to vendors. Minimum rates should be fixed to the quality categories of fruits so that farmers will not be losing in any season. Farmers should also be able to sell their produce on online platforms where they can get fair prices. But to achieve that they should be producing them in huge quantities. 

Anything else that you would like to add?

For many years farmers have been at a great loss due to unseasonal rains and lack of evidence-based suggestions by local agriculture experts, using technology and proper planning should bring good results in the future. Failure is an opportunity to begin again more Intelligently.


Protecting cannabis plants with the help of beneficial insects

Beneficial insects are a natural and safe form of pest control. They are a great alternative to pesticides and they are not harmful to the environment. The use of beneficial insects is becoming more popular in the face of pesticide resistance and growing public concern about the risks associated with chemical pest control. A number of factors must be considered when selecting beneficial insects for release into a particular environment: the type or species of insect; their life cycle; how fast they multiply in numbers; whether they are native to that area or not; where they will live in the environment; what they will feed on and more. The use of beneficial insects is becoming more common in the cannabis industry as it has been proven to be a sustainable way to decrease the use of pesticides while still maintaining the desired level of quality for the product.

In the following, we review the common insect pests that affect cannabis and the beneficial insects that can come to the rescue.


Aphids are small polyphagous (0.5-5 mm), sap-sucking insects that come in various colors and shapes. Most aphids don’t have wings, but the ones that do range in colors from black, green, pink, yellow, etc. Aphids are one of the most widely distributed pests in the world.

Feeding can cause stunting and plant/leaf deformities such as curling, while honeydew secretions are a “fertile ground” and a major contributor to the development of sooty mold fungi that in turn can lead to a decrease in photosynthesis.

Aphids are a major vector for dozens of viruses. That alone is enough to put aphids at the top of the most globally, economically hazardous list for crops.

aphidius colemani

This parasitic wasp is part of the family Braconidae and feeds on several species of aphids, including the peach aphid and the pumpkin aphid. The adult wasp is thin with black, brown, and yellow colors in its different body parts.

It is sensitive to high temperatures and its optimum temperature range happens to be 20-30 degrees Celsius. It lays a single egg inside the aphid’s body. The hatched larva feeds on the internal tissues of the aphid. The aphid becomes a “mummy” with a swollen, brown appearance.


Considered to be soft scale insects, mealybugs derived their name from their appearance. Usually, mealybugs are covered with a sticky wax floury or cornmeal-like whitish powder. Some species reproduce sexually, while others are parthenogenic. Mealybugs may be oviparous, viviparous, or ovoviviparous. Their eggs are usually laid in loose masses of cottony wax ovisacs. The flowering and fruiting phases of plants help support a larger mealybug population.

They feed on the phloem by sucking sap from plants. Symptoms appear as small white patches on stems and fruits, followed by the formation of honeydew and the development of sooty mold near infected areas. Mealybugs are known for their ability to transmit plant viruses and can cause heavy losses.


Anagyrus pseudococci

A parasite that lays a single egg into the mealybug body. The larva that hatches from the egg feeds on the mealybug body and mummified it.

Cryptolaemus montrouzieri

Coccinellid predator that reaches 4 mm long in its adult form; The insect color is dark brown with an orange abdomen. Young larvae prefer mealybugs eggs and larvae, while adults feed on all stages of the pest without preference.

The optimal conditions for its development are 26 Celsius and 60% humidity.

Red spider mites

Red spider mites are small arthropods that are classified as Arachnida and members of the Tetranychidae family, along with hundreds of different species. They are distributed worldwide and considered a persistent concern for farmers in warm, arid, and dry weather regions.

When weather conditions are right, a female is able to lay up to seven eggs a day and will do so on the underside of leaves. Adults feed upon plant tissues leaving yellowish nourishing marks. 

Red mite presence in fields could go unnoticed until infestation reaches a critical point in which damage to plants is clearly visible. 


Amblyseius swirskii

This particular predatory mite belongs to the Phytoseiidae family. It’s known as the swirskii mite and is a general carnivorous critter that consumes pollen from flowers, as well as Western flower thrips, whiteflies, and red mites.

The mite color can be white, white-yellow, and even light orange. Its color depends on the color of its prey.

The optimum for its development is 25-28 degrees Celsius; The duration of development from egg to adult at a temperature of 26 degrees Celsius lasts about 5-6 days.

Phytoseinulus perssimilis

The Presimilis mite, belonging to the Phytoseiidae family of predators, preys on other mites and small insects. These predatory mites can act as a natural way to keep certain pests in check and are especially effective due to their specificity.

Females are pear-shaped. They have a red-orange hue and with their long front legs and rapid movement can capture red mites with ease. The pest feeds on red mites in all growth stages, with a preference for eggs.

The optimal conditions for their development are 21-28 degrees Celsius and a humidity of 60%. In optimal conditions, the pest completes its life cycle within a week.


Leafminers are insects belonging to different orders: sawflies belong to hymenoptora, flies belong to the order of diptera, and moths that belong to the order lepidoptera. Together, they form a large group of plant pests that are important to cultural crops around the world.

Feeding patterns are important in helping identify the genus and the species, and it is quite characteristic. Leafminers are year-long pests that favor warm environments.

The first signs of infestation are tiny yellow dots upon leaves’ upper surfaces. The spots depict where the female laid her eggs. A week after, maggots begin eating their way inside the leaf tissue thus creating those complex tunnels we recognize so easily. The tunnel provides sufficient living conditions for the larvae. In the following 10 days, the tunnel gets wider and longer. Eventually, maggots pop out and fall to the ground where they’ll complete their metamorphosis and turn into a fly after another 10 days.

Its larvae stage is the one responsible for the actual damage. In a large enough population, it can cause a significant drop in yields due to sabotaging photosynthesis.

Diglyphus isaea

The parasitic wasp Diglyphus belongs to the family Eulophidae. a natural enemy of dipteran leafminers and a successful commercially available biological product against leafminers.

Diglyphus acts as an external parasite and lays eggs outside the host’s body. The adult is small, and is black in color with a metallic green sheen, protruding from its surface.

The female injects the leafminer maggot with paralyzing fluid before laying eggs and depositing them close to its body. The maggot stays paralyzed for two weeks and the larvae that hatch from the egg (after two days) feed on the pest. The adult female is nourished by the body fluids of the pest maggots as well.

At an optimal temperature of 20-25 degrees Celsius the graduates are able to live up to 30 days.


Bemisia tabaci, also known as whitefly, is a multi-host with considerable differences that exist in appearance between adult and nymph stages. Females can lay dozens of eggs, usually on the underside of leaves. Nymphs feed by stabbing into the plant with their mouth parts, sucking up sap from the phloem, and excreting honeydew (a sugar-rich substrate that promotes the growth of sooty mold.) The adults are white and capable of flying, hence the name.

Damage to hosts is caused directly by feeding and indirectly by honeydew. However, their ability to spread viruses has the greatest economic impact. Whitefly vector plant viruses like Begomoviruses, which is a group of plant viruses such as TYLCV in tomatoes and CYSDV in cucurbits. Whiteflies transmit Begomoviruses to host plants.


Macrolophus pygmaeus

This light green insect is a predator of small arthropods. It is considered an effective predator of whiteflies and tuta absoluta but also feeds on eggs of the whiteflies, thrips, mites, and aphids.

Amblyseius swirskii

Refer to the sections above.

Western Flower Thrips

Western flower thrips are small, polyphagous insects (adults are 1.2 mm in length). They are a major pest in the world of agriculture with several hundred different host plants. They can usually be found on the upper parts of plants, especially inside the flowers, where they feed on pollen. Western flower thrips undergo partial metamorphosis, developing through several distinct stages, including egg, larva, pupa and adult-which can fly only weekly.

They can cause damage to crops directly as a result of feeding or laying eggs in the plant’s tissue and indirect damage from the role it plays as a vector of viruses.

Orius laevigatus

The carnivorous flea Orius is a relatively small insect that belongs to the family Anthocoridae.

It feeds mainly on insects, but also on plants. When feeding on plants, it feeds on the sap and pollen, without harming the plant. Pests such as western flower thrips, whiteflies, and red mites are its source of prey. At an optimal temperature of 25 Celcius, the flea completes its development from egg to adult within 16-18 days and can live up to a month. Luckily, at all stages of development, it can devour pests.

Macrolophus pygmaeus

Refer to the sections above.

Further considerations

When the infestation is getting out of control chemical insecticides might be required. On such occasions, there is a need to select pesticides that are not harmful to the beneficial insects. The Agrio app can help you to choose the right product.


Integrated pest management is the approach of combining methods that work better together than separately. It allows diseases and pests to be controlled by managing the ecosystem, which results in long-term pest control that is less risky to farmers and the environment. IPM is an environmentally sound approach that has been shown to reduce pesticide use by 80% or more compared with conventional pest control approaches. We look forward to seeing you leveraging this information for intelligent and effective pest management in your growing areas. 

In the meantime, as always, we wish you an abundant harvest.


Satellites with red-edge sensors help to detect plant stress early

In the effort to grow better food farmers and crop advisors want to have a better understanding of the condition of their crops in real-time. Such information can allow them to detect plant stress early before damages are becoming substantial.

Remote sensing is a new revolutionary approach that can help to accomplish that. It is an affordable way to identify plant diseases and other problems early on, which can then be treated before the problem spreads and damages the entire crop. Remote sensing leads to more efficient food production, which in turn helps to increase crop yield and decrease hunger worldwide.

It is well known by now that the visible spectrum can be limiting when it comes to the early detection of plant stress. When you scout your plants you might not be aware of the symptoms that are already developing. These symptoms might be presented in the field but not yet visible as symptoms that are visible to the naked eye. Hyperspectral imaging can solve this problem, as it is shown to have promise in the early detection of plant stress. It was demonstrated that the symptoms of stressed plants show in some spectral regions before they can be seen in the visible spectrum.

The red-edge spectrum and early plant stress detection

One of the interesting spectral regions is the red-edge. This is the region that shows a large sharp rise in the plant absorption of light. This region is characterized by electric waves with wavelengths between 700 to 800 nm. The sharp incline in the graph is due to the contrast between the strong absorption of chlorophyll and the otherwise reflective leaf. This spectral region is proving to be the most sensitive to disease symptoms and could serve as a leading indicator when it comes to detecting plant stress early.

This led to the increasing number of satellites that were sent to space that carry sensors that are sensitive to these wavelengths. Moreover, there is an increasing amount of research effort that deals with the classification of healthy and infested plants based on spectral signatures in the red edge spectral region. In recent years there is an increasing amount of evidence that shows that the red-edge shows signs of a problem before the condition is detectable with traditional vegetative indices or the naked eye.

Typical plant light reflectance
Typical plant light reflectance

Satellites with red-edge sensors

Some of the satellites that carry red-edge sensitive sensors are the Sentinel-2 and PlantScope constellations. Sentinel-2 has spectral channels with different spatial resolutions, including three 20 m resolution red-edge bands at 705 nm, 740 nm, and 783 nm. Planetscope satellites provide 8-band including 3 m resolution with red-edge sensitivity at 733 – 748 nm.

What makes the red-edge region interesting for analysis?

Studies show that the ratio of reflectances at 750 nm to that near 700 nm is directly proportional to the chlorophyll concentration in the leaves. Chlorophyll plays a crucial role in the photosynthetic processes such as light-harvesting, and thus the content of chlorophyll is a potential indicator of a range of stresses. Moreover, it was shown that red-edge absorption analysis can indicate a problem before the actual reduction in the chlorophyll can be observed. The chlorophyll functioning changes can be detected by the red-edge analysis early on. This precedes the actual losses in leaf chlorophyll concentrations and therefore monitoring such changes can act as an early indicator for the development of biotic and abiotic stress.

Another advantage of analyzing this spectral region is the invariance of the results to changing environmental conditions. The absorption and reflectance of the waves are less sensitive to soil background and atmospheric effects.

Some examples of diseases that their monitoring was studied with this approach are late blight in potato and rice panicle blast.

Leveraging artificial intelligence to detect anomalies in satellite imagery

After discussing the benefits that can result from monitoring the red-edge reflectance we need to deal with the question of the practicality of this approach. One of the challenges in leveraging spectral analysis in stress detection is to identify the precise patterns in the satellite scans that indicate that the plants are under stress. The use of artificial intelligence in agriculture has been on the rise due to the recent advancements in technology and contributes to the efforts to overcome these challenges. Anomalies are detected using artificial intelligence by making decisions that are based on patterns that were learned from large training datasets.

The progress in the development of early detection tools can become faster once a large volume of high-quality data can be collected in an affordable way. To achieve that we took the crowdsourcing approach and built a tool that allows growers to identify plant pathology based on smartphone captured images. Growers are directly benefiting from this service while helping to train algorithms for early detection, a capability that can be more beneficial for them in the long term. The geotagged images are used as ground truth and help us to train the algorithms to identify the problems directly from the satellite scan. The computer is presented with satellites scans in which it is known which of the field regions are diseased. We make fast progress as we are able to collect a large volume of high-quality data.

Monitor fields with the Agrio smartphone application
Monitor fields with the Agrio smartphone application

Such data allow us to learn the patterns of the typical reflectance patterns of a large number of different plant problems. We leverage these capabilities to develop easy-to-use monitoring solutions. Farmers that are using Agrio can monitor the health of their fields in a very simple way. All that is needed is to define the field location by drawing a polygon that represents the field boundary. Once this is done we are kicking in to do constant monitoring for you, and notify you when a new scan is available.

On our platform, users can get access to Sentinel and PlanetScope satellite scans. We apply our algorithm to the imagery to monitor crop progress, spot problems in the field, and alert growers when interventions are needed.

We invite you to leverage these capabilities to avoid losses, grow better, and spray less.


Remote monitoring of cornfields during critical reproductive stages

Corn tasseling is the reproductive stage of corn where the tassels, which are located on the top of the plant, produce pollen. The tasseling stage is important for both the yield and quality of corn and extra care should be provided that plants are in optimal conditions at this stage.

Despite the potential size of the ear already being determined during the previous growth phase, what happens during this period determines the plant’s ability to express the yield potential. The more pollination that occurs the better the eventual yield will be.

Corn tasseling

How does satellite imagery help farmers?

The ability to monitor crop progress and spot problems in the field before symptoms are apparent is crucial for a successful harvest. Exciting advancements in technology allow us to capture images of farms around the world with the aid of satellites, thus making monitoring simple and affordable.

In the tasseling phase, the crop is vulnerable to insect infestations and disease outbreaks. This phase lasts between 10 to 14 days and it’s crucial to keep an eye on the crop during this time. With the aid of remote sensing monitoring, we can identify the transition to the tasselig phase very accurately. The accuracy of the analysis is very high if we use satellites that visit the fields on a daily basis as we are able to provide the identification of the phase transition in a few days lag.

To monitor the phase transition we monitor the Leaf area index (LAI). LAI is a measure of leaf surface area per unit of ground area. Corn tasseling prediction based on leaf area index is a technique that uses LAI measurements to estimate when corn will enter its reproductive phase. Monitoring the leaf area index with satellites is a new and innovative way to monitor vegetation. It’s an alternative to traditional methods of monitoring vegetation with ground-based measurement.

Identification of the tasseling stage based on satellite monitoring
Identification of the tasseling stage based on satellite monitoring

Once we identified the phase transition we use the satellites scan to monitor the plant’s health. In the tasseling stage, it becomes crucial to inspect the plants’ health very closely. Any stress at this stage will result in irreversible losses and therefore a fast reaction is important. The high frequency of satellites visits is essential. With satellites that monitor the fields on a daily basis, growers can identify problems in the fields very early and prevent spread. The spatial resolution is important as well, and with a 3-meter scanning resolution, we are able to have a better capability to observe tiny changes in the plants’ health indicators.

Farmers that are using Agrio can monitor the health of their fields in a very simple way. All that is needed is to define the field location by drawing a polygon that represents the field boundary. Once this is done we are kicking in to do constant monitoring for you, and notify you when a new scan is available.

On our platform, you can get access to Sentinel and Planet scope satellite scans. With Sentinel we are able to provide 10-meter resolution scans with 3-5 days revisit frequency. PlanetScope is one of the satellite constellations operated by Planet. With daily revisits and 3-meter resolution, we can better deal with clouds interference and track the changes in the fields more closely. We apply our algorithm to the imagery to monitor crop progress, spot problems in the field, and alert growers when interventions are needed.

When a problem is detected in the scan it is important to go and inspect the plants. In the following, we provide a summary of the main problems that growers and crop advisors can expect to see in the reproductive phase.

Corn rootworm

Corn rootworm (Diabrotica balteata, Diabrotica undecimpunctata, Acalymma trivittatum, Diabrotica undecimpunctata howardi) larvae that have been feeding on corn roots will emerge as adults during the time from
tasselling through the silking and pollination period. Unsuccessful control of this pest can result in poor grain fill. The parasitic tachinid fly, Celatoria diabroticae is a good biological control option.

Corn rootworm
Corn rootworm


Armyworm can cause significant damage to crops and should be dealt with during the “grain fill” period. Weak plants tend to be stripped by caterpillars before larger, healthier plants. If you see 3-4 or more caterpillars per plant, it might be a good idea to spray insecticides so your crops can reach their full potential.

Prefer planting transgenic plant varieties known as Bt-varieties which have good resistance against this pest. Keep the close surroundings of crops neat by removing weeds, plant debris, damaged parts, unwanted plant growth, and closeby plants that are non-cultivated and unprotected.


European Corn Borer

The European corn borer passes the winter as a full-grown larva in corn stalks and weeds. There is a significant interaction between European Corn Borer and Anthracnose. When both are present, severe stalk damage and lodging can occur. Given the severity of the damages, it might be a good idea to harvest your plants early. This will limit the risk of you ending up with low yields due to your plants getting lodged.

Common rust

Rust as the name implies creates symptoms that are yellow to orange-brown or rust-colored on the top and bottom sides of infected leaves. Symptoms generally do not appear until after tasseling. The disease is caused by the fungus Puccinia sorghi and have easily wind-dispersed spores that put them among the most mobile plant pathogens around the world.

Rust disease symptoms on corn leaf

Northern leaf blight

Northern corn leaf blight (NCLB) is a fungal disease that often emerges where corn is grown year after year in the same field, especially where there is reduced tillage. NCLB favors high humidity conditions, but it has difficulties developing in extreme temperatures, such as very cold and hot temperatures.

Elliptical, “cigar” shaped symptoms first appear on lower leaves and move up the leaves as time passes. Severe yield loss is expected when outbreaks occur before the silking phase.

NLCB stays dorm in infected plant parts until weather conditions are favorable. NCLB infects newly planted corn through splashing water. Preparing the land with tillage practices and removing the previous season’s corn residue are essential for prevention. The presence of standing water will promote the spread of NCLB. Make an effort and improve areas on the field where water tends to accumulate and form puddles. If possible, cover the ground with polyethylene sheets to reduce water evaporation from the soil.

Eyespot is a fungal disease that is caused by the fungus Aureobasidium zeae. The pathogen overwinters in the residue from corn and therefore make it a routine to clean the field after harvest. Treatment is rarely warranted for eyespot in corn.

Eyespot disease symptoms on corn leaf

Head smut

Head smut of corn is caused by the fungus Sphacelotheca reiliana. When scouting look for ears and tassels that were replaced with smut sori filled with teliospores.

This fungal disease can be common in certain areas. It is advised to treat the seeds with fungicides in such cases.


Anthracnose in corn is a foliar disease that could be common in fields if they have not been left with corn debris from the previous year. Leaf spots typically emerge on lower leaves during wet, cloudy weather. Symptoms, which are easily overlooked at first, can look like small oval/elongated water spots on leaves. The spots form become tan with light orange to red borders. These spots coalesce and cause leaf blight. You may also notice circles of tiny black dots in the middle of blighted spots – these are fruiting bodies of the fungus. This fungus may also cause severe top dieback and stalk rot.

Other things to be aware of while scouting

  • Check for nitrogen and potassium deficiency by looking at the bottom leaves of plants.
  • Plants might turn purple if the pollination or kernel formation was unsuccessful.
  • Drought-like conditions can cause plants to flower earlier than expected. In addition, such conditions can cause a delay in the silk emergence. Irrigation should be provided if possible. Poor anthesis or pollen shed are other symptoms of drought stress.


We emphasized the importance of crop monitoring during the tasseling stage. Monitoring fields with satellites can make our lives simpler as they can help us identify the diseases that are affecting cornfields and the nutrient deficiencies in them. This will help us identify the areas where we need to take measures for prevention. Satellites can also be used to monitor a large number of fields, which is not possible with manual monitoring. This will allow us to get early warnings and exact locations of any potential problems.


Integrated pest management in stone fruit trees in early spring

Integrated pest management is a strategy that farmers can use to combat pests and diseases in their crops. This strategy has been used for many years and is still an effective way to manage pests. In the early 1990s, integrated pest management (IPM) was first introduced in stone fruit trees. It has been used ever since as a way to control the spread of pests and diseases in these types of trees. Farmers have found this method more cost-effective than other methods on the market today.

This article will cover some of the important aspects of Integrated pest management in stone fruit trees and how it can be used to improve productivity and reduce pesticide usage.

Wilsonomyces carpophilus

During the rainy winter months, the fungus attacks the dormant buds and a resin secretion is seen as a result.

The symptoms on the fruit and leaves begin as reddish spots that on the leaves soon become necrotic and dehydrated. Due to this, the inner part of the spot falls, leaving a perforated appearance (shot hole). Young green branches are affected by the disease and develop cankers. Fruits can become deformed.

Remove as much infected plant tissue as possible during the summer. At the beginning of fall, before rains start, spray with a Bordeaux mixture or copper-based fungicide. Repeat application in the spring before and during bloom. Dithianon-based fungicides can be used during the season before rain events.

Shot hole disease
Shot hole disease


The damage can be seen on the branches in the form of gummosis. Prevention should focus on keeping stress factors low and spraying with preventative fungicides after pruning or tissue injuries.


A fungal disease that causes defoliation and decreases the fruit yield as a result. In the end of each season remove all the affected leaves and clean the orchard. During the spring, preventative fungicides applications are needed if the humidity reaches high levels. Tebuconazole, Myclobutanil, and Cyproconazole can be considered. Applications should be continued in 2-3 weeks intervals until the middle of the summer.

Powdery mildew

Preventative spraying applications should be focused on protecting the fruits. Therefore, such applications should be performed right after the pollination and until the fruit kernel hardens. After that protect the foliage by removing plant parts that are highly affected and apply fungicides.

Peach leaf curl

This disease is caused by the fungus Taphrina deformans and affects peach, plum, nectarine, and almond trees. Peaches are the most susceptible crop and hence the name. The pathogen can be found on the host’s branches, buds, and bark. It can survive harsh weather conditions, withstanding summer’s high temperatures and prolonged dryness. At the end of a dormancy period, the fungus activity extends due to significant wetting events. As the weather changes and the flower buds swell, water splashes from irrigation or rain and cause fungus spores to reach the buds. That’s where the infection takes place, despite the fact that no green tissue is present. After the pathogen enters the host, it stimulates cells, which leads to abnormal growth. Visual symptoms first appear as reddish areas on newly emerged leaves. With time, swelling and leaf distortion cause fungus spores to break outside, release into the air, and infect new tissues. As the disease progresses, leaves may fall and be replaced by a new set of healthier leaves if a period of low humidity is present during their development. The loss of leaves during springtime results in decreased fruit production, and defoliation, and could expose branches to sunburn.

Control of peach leaf curl disease revolves around prevention through the use of chemical treatments. Broadly speaking, it is fairly common to perform two spraying treatments that are timed with respect to the physiological phase of growth. It is advised that the first treatment is implemented before buds swell, and the second treatment is implemented closer to the bud swelling process. Dithianon, captan, a copper-based fungicide, and bordeaux mix.

Peach leaf curl
Peach leaf curl

Peach twig borer

Anarsia lineatella (the peach twig borer) overwinters on the tree and the larvae emerge in the early spring. The larvae crawl out of hiding with the swelling of the buds. The pest attack flowers, leaves, and shoots. Later generations feed on fruits as well. It is difficult to monitor for it as it is found mainly in the upper third of the tree. Look for flag leaf withering as a sign of the pest presence. Remove such affected branches to lower the pest population.

At the beginning of the spring Install pheromone traps and check them weekly. Once the peach twig borer moth was captured trigger the biofix and follow the growing degree days model. The Agrio app will monitor the progress of the pest life cycle for you. Treatment should be aimed at the larvae. The monitoring of the emergence of the pest generations will help you time the Bacillus thuringiensis and spinosad insecticides optimally.

Almond bark beetle

Weak and degenerate trees, twigs that have dried up as well as trees that have withstood water should be inspected during the scouting. The beetle, in its various degrees, will be found in the woody parts that were recently dried. Look for rubber secretions as evidence of the presence of the pest. To make monitoring more robust, use pheromone traps to capture the adults. Remove and destroy all the infected wood in order to limit the spread.

Olive scale

Start monitoring after the oil spraying is done. Monitor trees that were infested in the previous season. Apply Neonicotinoid-based insecticides when 70% percent of the eggs were already laid. It is important to remember that repetitive usage of the same insecticides can cause resistance development among the pests and therefore under-optimal results.

European grapevine moth

The European grapevine moth (Lobesia botrana) feeds on the fruit. Look carefully in places in which it is hidden and protected such as under the leaves that cover the fruit. Use pheromone traps to monitor the pest presence more carefully.


Integrated pest management in stone fruit trees is a way of managing pests and diseases. It involves the use of early detection, preventative measures, and treatment methods to reduce the risk of pests and diseases. IPM is a cost-effective and sustainable pest control strategy that involves monitoring for pests, using pesticides only when necessary, and using natural predators to control the population of pests.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance with the product label. Keep in mind that information is written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biological, and to some extent, a small number of conventional chemical products, complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.


Integrated pest management in apple orchards in early spring

Pests are one of the biggest threats to apple orchards because they can cause a lot of damage in a short period of time. As such, it is important that farmers keep an eye out for any pests so they can take preventative measures before it becomes too late. In order to maintain the health of an orchard, it is necessary to have a pest management plan in place. A good plan in apple orchards will include integrated pest management (IPM) practices, which include monitoring pests, taking preventative measures, and early detection.

Growers should monitor pests such as apple maggot flies, pear psylla, and codling moth. These insects can be monitored by looking for their larva in the soil around the trees or by looking for their damage to the trees themselves. Monitor these insects every week throughout the growing season to determine which pest has the most negative impact on your orchard.

Two important fungal diseases that should be considered are powdery mildew and apple scab.

Powdery mildew

Remove as much of the infested branches before the orchard is waking up. Start monitoring before bloom. The first treatment can be combined with spraying against apple scab. Applications should be repeated every 7-14 days until the end of the growth.

Powdery mildew of apple
Powdery mildew of apple

Apple scab

The disease is caused by the fungus Venturia inaequalis. When bloom starts, inspect the leaves and fruits and look for dark powder stains. Combine systematic fungicides such as Difenoconazole with contact fungicides such as mancozeb. Make sure that the spraying is applied especially before rains. Contact fungicides can be applied right after the end of the rains.

To protect the crop from damages caused by pest insects pay attention to the following insects: Codlig moth (Cydia pomonella), San Jose scale, Leopard moth (Zeuzera pyrina), Almond bark beetle (Scolytus amygdali), Olive scale (Parlatoria oleae), and European red mite (Panonychus ulmi).

Apple scab
Apple scab

Codling moth

Codling moth larvae are one of the most destructive pests. Although it can attack various fruits, it mainly damages apples. This is the main pest of apples and needs to be managed in each orchard. Orchards should be scouted twice a week early in the season and once a week later on.

Use pheromone traps to attract male moths. Traps are made of plastic to create a passage and the bait is placed inside. The inner surface of the bottom is coated with a sticky material to hold insects when they fall into the trap. The traps are hung in on the tree at eye level, one for every two acres of trees. It should be installed before the pink stage of apple bud development and checked every day. A total of five moths captured in the trap is the threshold to set the biofix, this is the day in which growing degree days should start counted. Use the Agrio app to time the insecticide applications accurately.

Install pheromone traps and sticky tapes before blooming begins. The pheromone traps should be located in the canopy, protected from the wind. Lures should be replaced monthly. Monitor these traps regularly looking for adult males. Once males are captured set the biofix date to start tracking the crawlers emergence. Apply treatment aimed at crawlers. Make sure that the spraying covers the entire tree. Reinstalll the traps to track the emergence of following generations.

Start monitoring after the oil spraying is done. Monitor trees that were infested in the previous season. Apply Neonicotinoid-based insecticides when 70% percent of the eggs were already laid. It is important to remember that repetitive usage of the same insecticides can cause resistance development among the pests and therefore under-optimal results.

Leopard moth

The larvae burrow in the wood skeleton and cause degeneration and destruction of the wood. Identify active burrows and pull the larvae out with a thin steel wire. The sawdust should be scattered under the tree to allow identification in the case of renewed activity. Traps can be used to capture the female moth. Traps with pheromone should be hanged near wooded areas. Install sexual disruption as it is very effective against this moth.

Almond bark beetle

Weak and degenerate trees, twigs that have dried up as well as trees that have withstood water should be inspected during the scouting. The beetle, in its various degrees, will be found in the woody parts that were recently dried. Look for rubber secretions as evidence of the presence of the pest. To make monitoring more robust, use pheromone traps to capture the adults. Remove and destroy all the infected wood in order to limit the spread.


Integrated pest management in apple orchards is a way of managing pests and diseases. It involves the use of early detection, preventative measures, and treatment methods to reduce the risk of pests and diseases. Integrated pest management in apple orchards is a cost-effective and sustainable pest control strategy that involves monitoring for pests, using pesticides only when necessary, and using natural predators to control the population of pests.


What farmers need to know about pesticide weather considerations

The importance of pesticide weather considerations

There is a limited amount of time to control plant pests and diseases. As the time window opportunity might be even shorter due to unsuitable weather conditions, applicators need to be able to identify and plan accordingly. Pesticide weather considerations play a huge role in pesticide application timing. It can significantly impact the amount of pesticides that are sprayed, their effectiveness, and the risk of causing harm to the plants and the environment.

The 4 key weather factors in pesticide application success

The four key weather factors that affect pesticides are temperature, wind, precipitation, and humidity. The worst weather conditions for applying pesticides are strong wind, high temperature, intensive rain, and low humidity. The wind is a crucial factor because it affects how pesticides move through the air; The wind can carry agricultural pesticides far away from where they were sprayed, making them drift onto other people’s property. This decreases the effectiveness of the spraying and increases the risk of polluting the environment and harming people living in nearby areas. This is why farmers must take into account wind direction and speed when spraying their fields with agricultural pesticides in order to reduce spray drift.

Precipitation and humidity can also change how pesticides are distributed, but it has a more minor effect than wind. Temperatures of air and surfaces are important factors in the efficacy of pesticides. Different chemical compounds have different temperature ranges at which they are most effective. For example, the insecticide pyrethroid is most effective at temperatures higher than 50°F.

Spraying pesticides outside is not recommended when there is more risk for a high evaporation rate, degradation, and extended droplet lifetime. The degradation of pesticides can increase when the humidity is high. High humidity also decreases evaporation, resulting in extended droplet lifetime and increased drift risk. These also play an essential role in safety. Higher concentrations of pesticides in the air can lead to potential health risks for workers and nearby residents. Some pesticides are more sensitive to temperature changes than others. In warm weather, humidity should allow good evaporation conditions. This will ensure that the pesticides have less time to break down into toxic compounds while contacting the plants. Decisions on spraying in such cases become challenging as high temperatures make plants more vulnerable to pests and diseases. Their natural defense systems break down and become more susceptible to pests and diseases like fungi and insects. Therefore, applicators need to carefully choose the timing of spraying to protect plants in such weather conditions.

A better way of telling how quickly pesticide droplets evaporate is the Delta T indicator. Delta T is the difference between wet and dry bulb temperatures, which can be calculated by combining the effect of temperature and relative humidity.

Delta T and preferred spraying conditions
Delta T and preferred spraying conditions

Growers should also pay attention to the inversion phenomena. Inversion happens when the temperature increases with the distance from the ground. Spraying should be avoided in this case as the risk of drifting pesticides long distances is high. The inversion hazard is often highest from dusk to a few hours after sunset and weak at sunrise.

Rainfall can have a significant effect on the efficacy of pesticides. Rain has been shown to reduce pesticide washout in some instances and increase pesticide washout in others. The primary function of systemic pesticides is to be taken in by the roots, but the rain needs to be relatively light for this to happen without the effect of washing the active material away from the plant surrounding. In general, the plant will absorb most of the systematic pesticide solution within about 2-4 hours. Therefore, it is essential to know how long you need to spray before the rain starts in order to get an acceptable level of control. In the case of contact pesticides, rains can wash out the active ingredient and damage the protective and curative effect that was intended.

Pesticides can be applied as a liquid, powder, or gas. The pesticide used depends on the crop and pest to be controlled. The method of application should be added to the set of considerations when weather conditions are considered. For example, herbicides can evaporate at a greater rate when sprayed under high temperatures, while fungicides can freeze at lower temperatures.

Generally speaking, the best time to spray is early morning or late evening when there is little wind, and the temperature is cool. In the case of insecticide, the evening is preferred as the interference with bees is minimized.

How technology can help you with timing spraying

With constant hyper-local weather monitoring and forecasting, we can show you the best spraying opportunities in the Agrio app. We save you time and present you with this information when you decide on a spraying application. In addition, our weather forecasts update every hour, so you can stay updated when forecasts are changing.

Pesticide weather considerations should be taken seriously before planning spraying applications. Using weather predictions to optimize treatment timings is an essential tool that will help you to optimize pest and disease control in your fields. We look forward to seeing you leveraging this technology for intelligent and effective pest management in your field. 

In the meantime, as always, we wish you an abundant harvest.


Collaborative tool for farm management

Farmers and crop advisors share a common goal of maximizing crop yield. They need to work together to make sure that all interventions are coordinated, which is where digital tools come in handy. Farmers can use their mobile devices for farm management, and to access information from the cloud, while crop advisors can use this data as well to create notes for future interventions. The instant sync feature ensures that changes made by one person will be updated on all other devices in real-time.

Although many communication channels already exist, there is a need to equip farmers with dedicated tools to help increase productivity. We introduce a new set of features to our mobile app to help teams to manage plant protection in their fields. Farmers and crop advisors will now be able to increase their collaboration and communication with each other.

Agrio | collaborative app for farm management

In the past, collaboration was only possible as part of Agrio’s Workgroup, which is intended for large groups of growers such as farming cooperatives. Today, we made it possible for Agrio users to collaborate on a single field. Farmers and crop advisors can now examine remote sensing insights, alerts, and information that was collected during the inspection process. Moreover, now they can assign plant protection-related tasks to each other and coordinate interventions in a simple way.

Team members are notified once satellite scans, preventative suggestions, and other recommendations are ready. Members can examine and analyze these inputs together and review the places in the fields that require attention. The scouting tasks can be assigned to the group members. Members are notified again once the fields were scouted and observations were uploaded to the system.

In the field, inspectors create geotagged digital scouting reports. Team members can see the observations that were collected, get updates on the parts of the fields that were inspected by other team members, and plan the scouting route accordingly. Discussions on the required interventions is becoming easier within the groups.

An AI-based assistant that helps you to create scouting reports

Team members can define tasks, such as trap checking, and be notified once tasks are completed by other members. Pesticides applications, fertilization, irrigation operations, and other interventions can be easily recorded using the field calendar. We use this information to send you reminders and let you know when we have insights on which interventions worked better. Use this tool to create experiments with different interventions and monitor their progress.


We believe that collaboration and communication are important for proper plant protection and farm management. We are excited to offer farmers and field inspectors this new capability and look forward to progressing the field of agriculture together.


Growing degree days and pest management optimization

With integrated pest management (IPM), monitoring crops and correctly identifying pests demands well-trained experts. The decision to choose one treatment over another is based on a set of factors that include the pest’s identity, the size of the pest population, the pest maturity stage, and the environment. If treatment is to be applied, it should be scheduled to make the most economic sense. Whether you are an agronomist, farmer, or gardener, tracking the growing degree days (GDD) can take your plant protection skills to a whole new level. Luckily this operation that is considered cumbersome, and requires phenology modeling understanding, is becoming very simple with technology.

GDD is a measure used to calculate the amount of heat required for the development of organisms (such as insects) in each stage of their growth. GDD is used to predict insects’ migration, egg hatching, fungal spore development, sexual maturity, and more. Operations that aim to reduce the population density of a pest need to coincide with the high presence of the most susceptible life stage of the species in the field. With insects, GDD can help us time the vulnerable stages of certain insects, such as the hatching of eggs of a particular pest. Compared with using the calendar method to estimate the organism stage, GDD is a more accurate method.

Each organism may require a different amount of accumulated heat to develop from one life stage to another. Phenology models are being developed and tested in laboratories and field experiments to provide accurate life cycle predictions. However, such procedures are expensive to conduct, and therefore the phenology models of many organisms are not readily available. Large-scale observations made by growers worldwide and reported on the Agrio platform is an easy way that allows the development and update of such models.

Combining a weather forecast with a rigid phonology model brings a new level of sophistication to pests, diseases, and weeds management.

Development thresholds

Phonology models predict the effect of temperature on the growth and development of biological organisms. Experiments show that there is a range of temperatures in which development is possible. The lower and upper developmental thresholds are usually used. When the temperature is below the lower developmental threshold, the organism is not expected to develop further. The upper developmental threshold is generally regarded as the temperature at which the growth rate starts to decrease. Both the lower and upper thresholds are determined through experiments and are unique to a specific organism.


The accumulation of growing degree days starts at the biofix (biological fix) date. The biofix can be a biological event or a calendar date that makes the organism’s survival possible. In case of a biological event, growers are required to scout their fields to time the event’s occurrence. In some cases traps installation and frequent examinations of the traps are needed to set the biofix accurately.

In many situations, the biofix is set based on the development stage of the plant. Satellite monitoring and weather models help us to forecast the plant stages for you. We send detailed information regarding scouting recommendations in every stage of the growth.

Area-wide Integrated Pest Management

Once precise methods are followed to decide on treatment schedules, there are vast options that become possible. One of the exciting possibilities is the alignment of treatment schedules in different farms and gardens. Communities of growers can consider the practice of Area-wide integrated pest management, which is the paradigm in which pest control decisions and timing are coordinated in many fields occupying a wide area. This approach is especially effective for mobile pests as it provides better control of pests in wide areas by eliminating the pest migration between fields.

Easy weather analysis and treatment optimization

Agrio makes precise hyper-local weather forecasts easily available to all growers. These state-of-the-art weather prediction models provide our growers an hourly hyper-local weather forecast designated specifically to their unique area anywhere in the world; the forecast is provided at a 3km resolution, so it is specific to their fields and gardens.

We help growers abandon cumbersome excel sheets and instead rely on our algorithms to do the GDD tracking for them.  We compute the accumulation of the growing degree days based on hourly temperatures instead of the more common practice of averaging the day low and high temperatures. This guarantees more accurate results. We manage the entire process for the grower in the following way:

  • The home screen’s daily briefing instructs growers on the required scouting operations and interventions in their fields. These are updated in real-time with the progress of the growing degree days accumulation, observations in the field made by the grower, and observations made by the community members in relevant proximity.
  • Agrio instructs growers when and how to set the biofixes promptly. We provide elaborate information on trap installation and maintenance as well.
  • Agrio tracks GDD according to multiple phonology models that correspond to different pests, diseases, and weeds in different fields or gardens that a grower manages.
  • We use big-data to optimize our predictions and offer phenology models particular to the different locations. We validate our phenology models continuously and adjust them when and where it is needed.
  • We coordinate area-wide integrated pest management operations and present users with the optimal IPM treatment on time.

The codling moth example

To demonstrate how this technology can help growers, we want to discuss the tracking of growing degree days for a specific example. We will discuss the management of the codling moth in apple orchards.

Codling moth larvae are one of the most destructive pests. Although it can attack various fruits, it mainly damages apples. This is the main pest of apples and needs to be managed in each orchard.


To monitor the presence of adults in the orchard, growers need to install pheromone traps. The trap’s purpose is to attract male moths, and they should be installed before the pink stage of apple bud development. The trap’s inner surface is coated with a sticky material to hold insects when they fall into the trap. Traps should be checked by growers every day, and the trapped moths should be counted in each area separately. A total of five moths captured in the trap is the threshold to set the biofix; this is the day on which growing degree days will start to be tracked by the app. The accumulation of growing degree days is used to predict when egg hatching will occur and when pesticide application will be most effective.

Before the pink stage of the apple buds development, Agrio notifies growers that pheromone traps should be installed. The information page provides all the required instructions for the installation. In addition, the information page instructs the grower what requirements need to be satisfied to set the biofix.

Treatment instructions

Once the biofix was set, Agrio starts to track the GDD and shows an estimation of the time until the next spraying is due; growers should stay tuned and follow the instructions in the daily briefing section on the app. Notifications are sent as a reminder when important events are near. Growers can use our image identification capabilities if help is needed with the trap analysis, as precise identification of the moth can be challenging. The aim is to spray when the eggs are hatching; this is when growers will be notified with information on the required intervention.

The colorado potato beetle example

Colorado potato beetle | weather-smart treatment plan

The colorado potato beetle is a pest that can destroy the potato, eggplant, and pepper crops. If it is not controlled, the beetle will reproduce rapidly and cause damage to the plants. The life-cycle of the potato beetle can be predicted by using a weather-based model. It is important to know the vulnerable period of the pest in order to determine when it is time to spray. This can help in controlling the pest population and reducing pesticide use. The life-cycle of this pest can be predicted by using weather-based models. This model predicts the optimal time to apply pesticide treatments.

Female adults produce hundreds of eggs each year. The eggs are usually bright yellow to orange and typically found in clusters of ten to thirty, on the underside of leaves. The model estimates when frequent scouting needs to be started in order to find signs of the eggs’ presence. Growers are notified and asked to confirm the eggs’ presence in order to start the life-cycle tracking.

The larvae should hatch from the eggs in 4-9 days depending upon the temperature of the air. After this, they will molt 3 times before they pupate. These immature phases are called instars, and there are a total of 4. Biological treatment is effective against the first-stage larvae, and chemical spraying should be timed to the emergence of later stages. The number of pest generations in one season is also weather-dependent, and the model will estimate it for you, too.


We are adding new crops and new pest models on a regular basis. Please write to us and tell us which pests you want us to prioritize.

Monitoring GDD helps eliminate the guesswork in determining the time required for control measures. We look forward to seeing you leverage this technology for smart and effective pest management in your field. 

In the meantime, as always, we wish you an abundant harvest.


توقعات الطقس المحلي لتحسين الزراعة

من الزراعة إلى الحصاد، يعتبر الطقس أحد العوامل الرئيسية من أجل حصاد ناجح. توقعات الطقس هي أداة أساسية للمزارعين الذين يرغبون في ضمان محاصيل صحية وانتاجية عالية.

تؤثر الظروف الجوية على المحاصيل من البذور إلى الفاكهة ويجب أن تؤثر على القرارات التي يتخذها المزارعون في الحقل لزيادة الجودة والمحصول. يمكن تحسين الري وإدارة الآفات والأمراض والجوانب الأخرى إذا تم التخطيط وفقًا لذلك. يمكن أن تحدد الظروف الجوية أيضًا كيف ومتى يمكن القيام بالعمل في الحقل، ويمكن أن يتغير (أو حتى يمنع) الحصاد.

في هذه المقالة، سنناقش اعتبارات الطقس المهمة خلال موسم النمو وسنصف كيف تتيح التطورات التكنولوجية للمزارعين استنباط خطط الطقس والبقاء على اطلاع دائم بتنبؤات الطقس كما لم يحدث من قبل.

اعتبارات درجة الحرارة للزراعة والحصاد

يتأثر نمو النبات بشدة بالتعرض لدرجات الحرارة المحيطة. بشكل عام، تعمل الأيام الأكثر دفئًا على دفع نمو النباتات بينما تعمل الأيام الباردة على إعاقة النمو. يشار إلى الدرجات المتراكمة فوق الحد (درجة الحرارة الأساسية) بأيام درجة النمو (GDD). يستخدم هذا لتقدير نمو بعض النباتات خلال موسم النمو. تعتبر الطريقة تقديرًا أكثر دقة لمرحلة نمو النباتات مقارنة بعمر النباتات. يمكن أن يساعد تتبع GDD المزارعين في تحديد توقيت الإخصاب والحصاد.

من ناحية أخرى، يعتمد إطلاق السكون الشتوي في بعض النباتات على وجود عدد كافٍ من ساعات البرد المتراكمة، كما هو في التفاح أو العنب. إذا لم تنخفض درجة الحرارة بدرجة كافية، فقد يصبح التحرر من السكون وما يتلوه من ازدهار النبات ضعيفًا وغير متساوٍي. في غياب الظروف المثلى، يحتاج المزارع إلى استخدام مواد كيميائية “لإيقاظ” النباتات وحثه على ازدهار موحد.

عند الزرعة، يجب الإجابة على عدة أسئلة. هل كان هناك تراكم مائي كافٍ في التربة لتنبت البذور وتنمو؟ هل الأيام التي تلي الزرع ستشهد ما يكفي من ضوء الشمس؟ هل هناك خطر التجمد؟ أيضًا، في بعض المحاصيل، تكون درجة الحرارة في وقت الحصاد مهمة. على سبيل المثال، يكون محتوى السكر وتكوين عنب النبيذ أكثر استقرارًا في درجات الحرارة المنخفضة، لذلك غالبًا ما يتم حصاد العنب في الأوقات الباردة من اليوم.

يعد التنبؤ الدقيق بالطقس على المدى الطويل والقصير أداة حاسمة للمزارعين عند الحاجة إلى التخطيط مسبقًا لتوقيت الزراعة والحصاد.

تخطيط الري

بمجرد زرع الحقل، تساعد التنبؤات الجوية المزارعين على تحسين ظروف النمو. يمكن أن يساعد التنبؤ بالطقس في تخطيط جداول ري فعالة توفر المياه وتقلل الاعتماد على الري. يمكن توقع معرفة الأيام الحارة والجافة مسبقًا للسماح بالري الفعال الذي يمنع إجهاد النبات. عوامل أخرى مثل درجة الحرارة والرطوبة وشدة ضوء الشمس والرياح مهمة أيضًا، مثل فقدان الماء من التبخر من النباتات والتربة (المعروف باسم التبخر النتح) يتأثر بهذه العوامل. إن المقدار الكبير من المتغيرات التي يمكن أن تتغير والوتيرة العالية لتغييرها يجعل التخطيط لجداول الري الفعالة أمرًا معقدًا. يوفر تتبع هطول الأمطار والتبخر من خلال المساعدة التقنية طريقة سهلة وعملية لتطوير خطط ري دقيقة يتم تحديثها باستمرار مع تغير الظروف الجوية.

إدارة الآفات والأمراض

لا تفرض الظروف الجوية سلوك النبات وتطوره فحسب، بل تؤثر أيضًا الظروف الجوية بقوة على ظهور الآفات والأمراض وتطورها مثل هجرة الحشرات، وفقس البيض، وتطور الأبواغ الفطرية، والنضج الجنسي، إلخ.

يؤدي الجمع بين التنبؤ بالطقس والمعرفة بتطور آفات أو أمراض معينة إلى مستوى جديد من التعقيد في إدارة الآفات والأمراض. تستخدم التنبؤات الجوية وGDD  للتنبؤ بالوقت المحتمل لظهور الآفات. ثم يعرف المزارعون متى يبحثون عن الآفات وكيفية تحديد الوقت الأمثل لتطبيق التدابير الوقائية ومبيدات الآفات. على سبيل المثال، عادةً ما تبدأ العثّات البالغة من حفار الذرة الأوروبي في الظهور والتزاوج في الربيع تقريبًا، عندما يبدأ الطقس في الدفء. يتم وضع البيض على الجانب السفلي من النباتات المضيفة، وفي غضون عدة أيام، تفقس على شكل يرقات وتبدأ في التغذية. من خلال حساب GDD، يمكن للمزارع أن يتنبأ بظهور العث ويطبق تدابير وقائية عندما تكون الآفة أكثر عرضة للخطر (وقبل حدوث الضرر).

يمكن للتخطيط الذكي القائم على الطقس أيضًا منع التطبيقات المهدرة لمبيدات الآفات والأسمدة. يمكن استخدام مبيد آفات كيميائي أو سماد قبل غسل المطر مباشرة ولن يكون له تأثير يذكر أو لا تأثير له. تطبيقات مبيدات الآفات في الأيام العاصفة هي أيضًا مواقف يجب تجنبها، حيث يمكن أن يكون للرياح تأثير سلبي على تشتت المبيدات وقد تسبب أضرارًا في الحقول المجاورة بسبب الانجراف. يجب تجنب الرش عندما تكون سرعة الرياح أعلى من 15 كم / ساعة.

يجب أيضًا أن تؤخذ درجة الحرارة في الاعتبار عند تحديد وقت الرش بسبب عدة عوامل مثل احتمال تبخر القطيرات، وخطر السمية النباتية والمزيد. بشكل عام، يجب تجنب رش المبيدات إذا كانت درجات الحرارة أعلى من 30 درجة مئوية.

الرطوبة النسبية في الهواء هي عامل مهم آخر يؤثر على تبخر القطرات. يجب تجنب الرش عندما تكون الرطوبة منخفضة.

إن معرفة الأيام المناسبة لاستخدام المبيدات والأسمدة قد يحدث فرقًا بين الحقل الصحي والحقل غير الصحي.

التنبؤ بالطقس

يستخدم المزارعون عدة طرق للتنبؤ بالطقس. وتشمل هذه محطات الطقس الإقليمية الكبيرة التي تستند إلى قدر كبير من المعلومات وتوفر معلومات دقيقة ومنخفضة الدقة لمحطات الطقس المحلية التي تكون أكثر دقة في المنطقة، ولكنها باهظة الثمن نسبيًا وتتطلب التثبيت والصيانة.

جعلت أجهزة الكمبيوتر الأفضل والأسرع وأدوات القياس الدقيقة من نماذج توقع نتيجة الأرصاد الجوية وتوقع الطقس أكثر موثوقية من أي وقت مضى. يتم جمع ملاحظات مثل درجة الحرارة والرطوبة وخصائص الرياح من مصادر مختلفة مثل محطات الطقس ورادارات الطقس والطائرات، والتي يتم إدخالها بعد ذلك في أجهزة الكمبيوتر لإنتاج محاكاة لتوقعات الطقس. كلما كانت المدخلات أكثر دقة ووفرة، كانت التنبؤات أكثر دقة. تسمح القوة المتزايدة لأجهزة الكمبيوتر بتحسين التنبؤ المتكرر الذي ينتج عنه تنبؤات عالية الدقة في المكان والزمان.

تجعل هذه التطورات التكنولوجية من الممكن تزويد المزارعين بتنبؤات عالية الدقة بطريقة ميسورة التكلفة، حتى في البلدان الريفية ذات الدخل المنخفض التي ليس لديها إمكانية الوصول إلى أجهزة قياس الطقس أو محطات الطقس المحلية بأسعار معقولة. هذه الأساليب الجديدة مهمة لأنها يمكن أن تتنبأ بالمناخ المحلي على مستوى الحقل، مما يسمح للمزارعين بالاستعداد والتخطيط للمستقبل.

Agrio يساعدك على التخطيط للمستقبل

يمكن أن يؤدي الجمع بين التنبؤات الجوية والمعرفة الزراعية إلى نتائج قوية. يوفر Agrio تنبؤات الطقس الدقيقة المحلية بسهولة لجميع المزارعين. تجمع نماذج التنبؤ لدينا بين قياسات وملاحظات الطقس من مصادر مختلفة. توفر نماذج التنبؤ بالطقس الحديثة هذه للمزارعين لدينا تنبؤات جوية شديدة المحلية كل ساعة مخصصة لمنطقتهم الفريدة في أي مكان في العالم؛ يتم توفير التوقعات بدقة تبلغ 3 كيلومترات لذا فهي خاصة بحقولهم.

سببان مهمان لتطبيق تناوب المحاصيل في موسم الزراعة التالي

تناوب المحاصيل هو ممارسة زراعة محاصيل مختلفة في تسلسل في نفس الحقل وقد تم استخدامه كأداة مهمة لتحسين الزراعة منذ الأيام الأولى للزراعة. في هذه الممارسة، يخدم كل محصول غرضًا مختلفًا في ترتيب التناوب. يتم تصنيف المحاصيل إلى مجموعتين رئيسيتين: المحاصيل المغذية ومحاصيل الغطاء. المحاصيل المغذية تعمل على تغذية التربة، بينما تستخدم محاصيل الغطاء لإصلاح التربة والسماد الأخضر والوقاية من التآكل.

الفوائد الرئيسية لتناوب المحاصيل هي إدارة الأمراض والآفات والحفاظ على التربة واستعادتها. رغم ذلك، هناك فوائد إضافية مثل تقليل الاعتماد على المواد الكيميائية ورعي الماشية التي لن تتم مناقشتها في هذا النطاق.

المحاصيل المغذية

شينوبودياسي (مثل السبانخ والشمندر)
البراسيكا (مثل البروكلي والملفوف)
القرع (مثل الخيار والبطيخ)
الباذنجانية (مثل الطماطم والبطاطس)
أليوم (مثل البصل والكراث)
حبوب الذرة

محاصيل التغطية

البقوليات (مثل البرسيم والفاصوليا)
الأعشاب (مثل الذرة الرفيعة والشوفان)

إدارة الآفات والأمراض مع تناوب المحاصيل

تعد الآفات والأمراض من أكبر التحديات التي تواجه المزارعين في جميع أنحاء العالم. والخبر السار هو أن تناوب المحاصيل يمكن أن يساعد في مكافحة الآفات والأمراض من خلال مقاطعة دورات الحياة وتغيير موائل الآفات.

يمكن منع انتشار الآفات والأمراض من خلال فهم دورة حياتها. تحتوي الفطريات والبكتيريا والحشرات والديدان الخيطية وحتى الفيروسات على مضيفات محددة يمكن إزالتها وموائل يمكن جعلها أقل ملاءمة لهم. يمكن أن يساعد هذا في تعطيل وتقليل انتشار الآفات والأمراض.

على سبيل المثال، إذا كان حقل البطاطس به إصابة بخنفساء البطاطس في كولورادو، فيمكن زراعة البرسيم في الموسم التالي لتقليل ضغط الآفات. ماذا ستحقق زراعة البرسيم في هذه الحالة؟ حسنًا، خلال مرحلة النمو، ستضع الخنفساء بيضها في الحقل. يفقس البيض في نباتات البرسيم، وهي ليست مضيفات قابلة لحياة الخنفساء. هذا يعني أن أعداد اليرقات ستنخفض بشكل كبير بسبب قلة حركتها (في مرحلة اليرقات، لا تمتلك الآفة أجنحة). من خلال تغيير موطن الخنفساء، وقطع دورة حياتها، يتم تحقيق منع تراكم أعداد الخنفساء في موسم الزراعة التالي.

إذا قام المزارع بزراعة البطاطس في الحقول المجاورة، فسيؤدي ذلك إلى تقليل فعالية استخدام البرسيم لتناوب المحاصيل لأن البطاطس ستعمل كمضيف مؤقت للخنفساء. يمكن أن تهاجر الخنافس مرة أخرى إلى الحقل الرئيسي في الموسم التالي عندما تتم زراعة محصول البطاطس مرة أخرى.

بينما يُزرع البرسيم في الحقل كمحصول تغطية، فإن الحشائش من الفصيلة الباذنجانية (مثل الباذنجان) قد تستضيف الخنفساء. وبالتالي، يمكن أن تعمل الحشائش أيضًا كمضيف انتقالي محتمل وتعمل كمضيف مؤقت للخنفساء. مثل هذه التحديات من بين أمور أخرى يمكن أن تعوق فعالية تناوب المحاصيل.

يمكن للمزارعين تحقيق عوائد أعلى من خلال فهم جيد لبيولوجيا الآفات والأمراض. هل للآفة أو المرض مجموعة واسعة أو قصيرة من العوائل؟ إلى متى يمكن للآفة أو المرض البقاء على قيد الحياة بدون مضيف؟ ما مدى انتقالها؟ هذه الأسئلة وغيرها تحتاج إلى المعالجة عند التخطيط لتناوب المحاصيل لإدارة الآفات والأمراض. بالإضافة إلى ذلك، من خلال الاعتماد بشكل أقل على المواد الكيميائية التقليدية لإدارة الآفات، هناك فرصة أقل لتطوير مقاومة الآفات والأمراض مما يؤدي إلى معدل نجاح أعلى في القضاء على المشكلة.

الحفاظ على جودة التربة وبناءها

في حين أن تأثير تناوب المحاصيل على حماية النبات هو اعتبار مهم لذاته، يحتاج المزارعون إلى الانتباه إلى جودة التربة. يمكن لسنوات وسنوات من الزراعة المكثفة لمحصول واحد أن تستنفد التربة وتستنفد مغذياتها وتضر ببيئة الكائنات الحية الدقيقة. يمكن أن يقلل هذا من المحصول، ويزيد من الحاجة إلى الأسمدة، ويزيد من مسببات أمراض التربة التي تضر بالنباتات. كيف يمكن أن يساعد تناوب المحاصيل في بناء صحة التربة الجيدة؟

من المعروف أن بعض المحاصيل مفيدة لصحة التربة؛ تُعرف هذه بمحاصيل الغطاء. تعزز محاصيل الغطاء صحة التربة وهيكلها، وتعيد المغذيات إلى التربة وتساهم في بيئة التربة.

تعتبر البطاطس مثالاً على محصول شامل، مما يعني أن مغذيات التربة يمكن أن تنضب بعد زراعة البطاطس على التوالي. يمكن للمزارعين منع المحاصيل المستنفذة من استنفاد التربة عن طريق زراعة محاصيل الغطاء. في هذه الحالة بقوليات مثل البرسيم.

لماذا البقوليات؟ من المعروف أن البقوليات من المحاصيل التصالحية. تحتوي البقوليات على بكتيريا تكافلية في نظامها الجذري تلتقط النيتروجين في الغلاف الجوي وتعيده إلى التربة في شكل متاح للنبات. تحتوي البقوليات أيضًا على جذر عميق يستخدم لإعادة تدوير العناصر الغذائية الموجودة في عمق الأرض.

يمكن استخدام الأعشاب كمحاصيل تغطية أيضًا. تمتلك الأعشاب أنظمة جذرية ليفية واسعة تفرز المواد في التربة وتعزز تراكم التربة. تعمل هذه العملية على استقرار التربة وتحسين التهوية. كما تتحلل جذورها ببطء وتعمل كمصدر للتغذية البطيئة.

ما يجعل محاصيل الغطاء أكثر إثارة للاهتمام هو حقيقة أنه يمكن استخدامها كسماد أخضر. في نهاية الموسم، يمكن تقطيع محاصيل الغطاء أو تركها لتتحلل في التربة. يؤدي القيام بذلك إلى إضافة مادة عضوية غنية إلى التربة وتعزيز صحة التربة. ومع ذلك، يجب التخطيط بعناية لاستخدام السماد الأخضر حيث أن المواد النباتية المتحللة قد تكون مصدرًا للتلقيح وانتشار مسببات الأمراض.

إن استخدام البقوليات أو العشب أو حتى ترك التربة مرتاحة لبعض الوقت يمكن أن يفيد بشكل كبير صحة التربة. يمكن أن يعيد العناصر الغذائية، ويعزز الكائنات الحية الدقيقة في التربة ، ويحسن بنية التربة.

التخطيط لدورة المحاصيل

يجب أن يقوم ضعف العائد والاعتماد الكبير على الأسمدة وارتفاع ضغط الآفات والأمراض بتحفيز المزارعين على وضع خطط لتناوب المحاصيل.

يمكن تقسيم تخطيط تناوب المحاصيل إلى عدة خطوات:

  1. تحديد محاصيل الغطاء المتاحة للاستخدام بناءً على الموقع والمناخ واتجاهات السوق المحلية والموسم للحقل المتاح.
  1. تحديد موعد زراعة محاصيل الغطاء. اسأل نفسك عن عدد المرات التي يمكنك فيها التناوب ونوع التناوب. هل ستزرع فقط في غير موسمها، أو لديك عدة مواسم متتالية من محاصيل الغطاء.
  1. تحديد غطاء المحاصيل التي يجب استخدامها: البقوليات أو الأعشاب. لكل من البقوليات والعشب متطلبات غذائية منخفضة نسبيًا ويمكن استخدامها كسماد أخضر. تشمل الاعتبارات الأخرى التي يجب مراعاة فوائدها الرئيسية:

فوائد البقول:

  • قادرة على التقاط النيتروجين الجوي (N)
  • إعادة تدوير المغذيات من التربة العميقة

فوائد العشب:

  • يعزز تراكم التربة والتهوية
  • يعمل كمصدر للإطلاق البطيء للمواد العضوية

ماذا أيضا؟

تعمل النظم الجذرية لمحاصيل الغطاء على تثبيت التربة معًا وتثبيت هيكلها مما يمنع الأمطار الغزيرة والعواصف من التسبب في تآكل التربة. تعزز محاصيل الغطاء حقلاً متنوعًا يمكنه مكافحة الأعشاب الضارة وقد يمنع نموها. بالإضافة إلى ذلك، فإن التناوب مع المحصول يسمح بمكافحة الحشائش بسهولة ويمنح المزارعين فرصة لتقليل تراكم الأعشاب الضارة.

عند استخدامه بشكل صحيح ، يمكن أن يكون تناوب المحاصيل أداة فعالة وإضافة قوية إلى إدارة المحاصيل. يمكن أن تكون فوائده واسعة وطويلة المدى لإدارة الآفات والأمراض من خلال مقاطعة دورات الحياة وتغيير الموائل، والحفاظ على صحة التربة واستقرارها وتعزيزها، وإثراء بيئة الكائنات الحية الدقيقة في التربة.

يمكننا مساعدة المزارعين ليكونوا أفضل وأكثر انتاجا وفعالية.

مراقبة المحاصيل ورسم خرائط محتوى الكلوروفيل عن بعد

تعد القدرة على مراقبة تقدم المحاصيل وتحديد المشكلات في الحقل قبل ظهور الأعراض أمرًا بالغ الأهمية لنجاح الحصاد. في هذه المقالة، نريد أن نناقش كيف يمكن لرسم خرائط التباين المكاني لمحتوى أوراق الكلوروفيل (LCC) داخل الحقول أن يساعد في اكتشاف المشكلات الصحية والكميات المختلفة من استخدام الأسمدة النيتروجينية.

يعتبر محتوى الأوراق من الكلوروفيل مؤشرًا مهمًا لصحة النبات وإمكانية التمثيل الضوئي والحالة الغذائية. على الرغم من أن تحليل الاستخراج عن طريق أخذ العينات الميدانية يوفر تقديرًا دقيقًا لحالة LCC، إلا أن هذه الأساليب ليست عملية. يوفر قياس الاستشعار عن بعد غير المدمر طريقة ميسورة التكلفة ومتكررة لتقييم LCC للنباتات في الحقول بدقة عالية.

يرتبط محتوى النيتروجين بالأوراق ارتباطًا وثيقًا بمحتوى الكلوروفيل. يعتبر المعدل الأمثل وتوقيت تطبيق الأسمدة النيتروجينية أمرًا بالغ الأهمية في تحقيق عائد مرتفع. تسمح مراقبة مؤشر الكلوروفيل باستخدام الأسمدة ذات المعدل المتغير وإدارة المحاصيل الخاصة بالموقع.

تعتبر ظروف الطقس والتربة من العوامل الرئيسية في معدل خروج النيتروجين من نظام التربة إلى الغلاف الجوي، وبالتالي لا يمكن التنبؤ بسهولة باحتياجات الإخصاب. يمكن للطرق الجديدة لمراقبة الحقول أن تقلل من تخمين المزارع عند اتخاذ قرارات استخدام الأسمدة في منتصف الموسم، وهو قرار مهم لأن تكاليف النيتروجين يمكن أن تحدث فرقًا بين الموسم المربح والموسم غير المربح.

لماذا لا يكون مؤشر الغطاء النباتي للفرق الطبيعي (NDVI) مناسباً لهذه المهمة؟ يُظهر NDVI ارتباطًا منخفضًا بمحتوى الكلوروفيل، وهو أكثر حدة في مراحل النمو المتقدمة عندما يصبح NDVI مشبعًا. يرجع هذا التشبع إلى الزيادة في مساحة الورقة وكثافة هيكل المظلة. في هذه المرحلة، هناك حاجة لمراقبة مؤشر مرتبط بشكل كبير بمحتوى كلوروفيل الأوراق وأقل حساسية للورقة وبنية المظلة.

يمكن للمزارعين الذين يستخدمون Agrio مراقبة المحاصيل ومؤشر الكلوروفيل في حقولهم بطريقة بسيطة للغاية. كل ما هو مطلوب هو تحديد موقع الحقل عن طريق رسم مضلع يمثل حدود الحقل. بمجرد الانتهاء من ذلك، نبدأ في إجراء مراقبة مستمرة لك، ابلاغك عند توفر فحص جديد.

مراقبة الحقول الزراعية بالأقمار الصناعية

تعد القدرة على مراقبة تقدم المحاصيل وتحديد المشكلات في الحقل قبل ظهور الأعراض أمرًا بالغ الأهمية لنجاح الحصاد. تتيح لنا التطورات المثيرة في التكنولوجيا التقاط صور للمزارع حول العالم بمساعدة الأقمار الصناعية، مما يجعل المراقبة بسيطة ومعقولة التكلفة.

مؤشر الغطاء النباتي الأكثر شيوعًا الذي يستخدمه المزارعون هو NDVI، وهو مؤشر على صحة النبات بناءً على انعكاس موجات الضوء المختلفة.

يمكن للمزارعين الذين يستخدمون Agrio مراقبة مؤشر NDVI لحقولهم بطريقة بسيطة للغاية. كل ما هو مطلوب هو تحديد موقع الحقل عن طريق رسم مضلع يمثل حدود الحقل. بمجرد الانتهاء من ذلك، نبدأ في إجراء مراقبة مستمرة لك، وإخطارك عند توفر فحص جديد. نتوقع أن يكون الفحص متاحًا كل بضعة أيام، ولكن عندما تكون السماء غائمة، ولا يمكن التقاط لقطة واضحة للحقل، نحتاج إلى انتظار المرة التالية التي يمر فيها القمر الصناعي فوق مجالك. تحدد خوارزمياتنا الغيوم في السماء تلقائيًا ونقدم صورًا مصفاة نظيفة من أي مصطنعات.

يمكن لمستخدمي Agrio توقع تلقي الصور التالية:


نقوم بتحليل الصور وننبهك عندما نجد حالات شاذة.

من أجل إعطائك بعض الحدس حول العملية، دعنا نشير إلى الشكل أعلاه. قد تشير المناطق التي يكون فيها الغطاء النباتي أقل مقارنة بأجزاء أخرى في الحقل إلى وجود مشكلة، وقد تكون هناك حاجة إلى الاستكشاف في هذه المناطق لمزيد من التحقيق في السبب. استخدم تطبيق Agrio للهواتف الذكية لتحميل صور الأعراض التي تجدها أثناء جولتك. سيساعدنا ذلك في تقديم توصية أكثر دقة وكذلك تحسين قدراتنا على تحديد المشكلات الدقيقة مباشرةً من صور القمر الصناعي أثناء تقدمنا.

علاوة على ذلك، يسمح لنا مؤشر NDVI بتقدير ما إذا كان المحصول يتطور في مرحلة جيدة. إذا كان المؤشر منخفضًا في منتصف الموسم، فمن المحتمل أن تكون هناك مشكلة تتطلب التحقيق، مثل نقص المغذيات على سبيل المثال.

نوفر لك الوقت من خلال تحسين طرق الاستكشاف الخاصة بك! نحن عيناك في السماء.

الذكاء الاصطناعي للإدارة المتكاملة للآفات

تؤدي ممارسات وقاية النبات الحديثة المطبقة في المزارع المدعومة جيدًا إلى مكاسب كبيرة في المحصول. لسوء الحظ، لم يتم اعتماد مثل هذه الممارسات على نطاق واسع ولا يزال من الصعب سنها لأن المزارعين يفتقرون إلى الدعم والمعرفة المطلوبين.

الإدارة المتكاملة للآفات (IPM) هي نهج الجمع بين الطرق التي تعمل معًا بشكل أفضل من العمل بشكل منفصل. يسمح بمكافحة الأمراض والآفات من خلال إدارة النظام البيئي، مما يؤدي إلى مكافحة الآفات على المدى الطويل والتي تكون أقل خطورة على المزارعين والبيئة. مع المكافحة المتكاملة للآفات، تتطلب مراقبة المحاصيل والتعرف على الآفات بشكل صحيح خبراء مدربين جيدًا. يعتمد قرار اختيار معاملة على أخرى على مجموعة من العوامل التي تشمل هوية الآفة، وكمية المحاصيل المتضررة، والبيئة. إذا كان سيتم تطبيق العلاج، فيجب أن يتم تحديده في الوقت الذي يكون أكثر منطقية من الناحية الاقتصادية.

Agrio هو حل رقمي يستفيد من تكنولوجيا الذكاء الاصطناعي لسد الفجوة في الدعم الذي يتلقاه المزارعون. يعمل Agrio على تسهيل التكيف الحديث لوقاية النباتات وهو سهل الاستخدام وبأسعار معقولة وقابل للتطوير. نحن نبسط تنفيذ الإدارة المتكاملة للآفات من خلال توفير الفوائد التالية لمستخدمينا:

طريقة سهلة لاستكشاف الحقول ومشاركة النتائج مع زملاء العمل

نحن نقدم نظام إبلاغ لا يتطلب جهد كتابة لتقديم أوصاف دقيقة لضغط الآفات والأمراض في الحقول. يتم تعزيز التقارير الرقمية تلقائيًا بالرؤى المستمدة من خوارزميات الذكاء الاصطناعي الخاصة بنا. أثناء عملية الاستكشاف، تتم مشاركة المهام القائمة على الموقع مع زملاء العمل لجعل إجراء العلاج أكثر كفاءة ودقة.

معالجة التحديات في التشخيص من أجل العلاج الأمثل

قد يجد المزارعون والمفتشون صعوبة في تحديد مسببات الأمراض الصحيحة، وكذلك تحديد العتبة الاقتصادية التي تتطلب برنامج العلاج. يمكّن حلنا المستخدمين من الاعتماد على خوارزميات الذكاء الاصطناعي المدربة جيدًا لتحديد المشاكل مع محاصيلهم واتخاذ قرار بشأن ضرورة العلاج. إذا تم اعتبار العلاج مطلوبًا، فإن الخيارات عديدة ولا توجد طريقة فعالة لاتباع بروتوكول يحتوي على أقل المخاطر البيئية والاقتصادية. يمكّن نظام دعم القرار لدينا المزارعين والمفتشين من اتباع نظام علمي متسق يعمل على تحسين عملية إدارة الآفات.

توقع المشاكل في وقت مبكر

يعد التوقيت أمرًا بالغ الأهمية عندما يتعلق الأمر بحماية المحاصيل، ويمكن أن يستفيد برنامج الإدارة المتكاملة للآفات الفعال من معرفة المزارعين لما يمكن توقعه قبل أن يصيب حقولهم. غالبًا ما تكون الوقاية هي أفضل خيار علاجي. في حالات الأوبئة الشديدة، تُترك المنظمات غير مستعدة عندما تغزو آفة أو مرض منطقة جديدة. يراقب Agrio الانتشار العالمي ويزود المستخدمين بتنبيهات للآفات والأمراض تسمح لهم بتقليل المفاجآت خلال مواسم النمو.

الإشراف على العمليات واسعة النطاق

تأخذ برامج المكافحة المتكاملة للآفات في الاعتبار الملاحظات العديدة التي قدمها المفتشون. من خلال نشر ملاحظاتهم في الوقت الفعلي، وتسهيل التواصل بين زملاء العمل، يقلل حلنا بشكل كبير من موارد الإدارة المطلوبة لإحاطة المفتشين، وتنسيق عمليات حماية الحقل، ومراقبة تقدم حالات تفشي المرض.

لقد قمنا بتطوير مجموعة عمل لمساعدة المجموعات الزراعية على التغلب على التحديات المذكورة أعلاه. مجموعة العمل هي أداة متكاملة لإدارة الآفات للمنظمات الزراعية؛ إنها أداة عمليات داخلية لإدارة مساعي حماية المحاصيل على نطاق واسع. مجموعة العمل قابلة للتخصيص والبناء؛ يمكن تحديد البروتوكولات والمدخلات الزراعية مسبقًا وعرضها على المستخدمين داخل قناتهم الآمنة. يتم عرض البيانات المنظمة من مجموعة العمل في لوحة القيادة لرفاهية الإشراف على حماية المحاصيل من المكتب أو المنزل. ترتب لوحة قيادة المعلومات للمشرفين الذين يريدون إدارة أكثر شمولاً لأنشطة حماية المحاصيل داخل مؤسساتهم. تسمح مجموعة العمل للمنظمات الزراعية بإدارة أنشطة لوقاية النبات على نطاق واسع.
