Who Am I?

Rose black spot is an important fungal disease of roses that is mostly active towards the end of spring. The fungus overwinters in infected plant debris from the previous season.

The fungus causes black spots to form on the upper surfaces of leaves. Defoliation can occur in heavily infected plants. Rain, overhead irrigation, and any other water-splashing sources triggers spores from infected plants debris.

Rose black spot tolerates a broad range of weather conditions, thus it allows symptoms to develop throughout the season.

Control Measures

रोग प्रतिरोधक पौधों की भिन्न प्रकारों और बीजों का प्रयोग करें।.

स्वच्छता : खरपतवारों, पौधे के अवशेषों, क्षतिग्रस्त भागों, अवांछित पौधों की वृद्धि, और आस-पास के खेती न किये गये क्षेत्रो और असुरक्षित पोधों को हटा कर आस-पास के क्षेत्र साफ रखें।

विश्व के एक अथवा अधिक भागों में प्रयोग किये जाने वाले उत्पादों में निम्न सामग्रियाँ हो सकती हैं :

एजोक्सित्रोबिन,ट्राईफ्लोक्सिस्त्रोबिन, म्य्क्लोबोटनिल्, पेंकोनज़ोल, पाइराक्लोसत्रोबिन, और क्रेसोक्सिम-मिथायल

*Names marked in red are considered to be highly poisonous to beneficial insects.

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 to the product label. Keep in mind that information 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, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
