Phytotoxicity occurs when substance causes a toxic effect on plants.
Phytotoxicity can occur when chemicals are applied, such as in foliar spraying and irrigation systems, in order to protect plants from diseases, pests and other hazardous. Additionally, phytotoxicity can occur following applications of fertilizers or growth regulators.
Reasons:
*Improper use: Applying off label brands, overdosing plants with chemicals, and applying concentrations that are too high.
*Timing: Applications took place in unfavorable environmental conditions, such as the temperature was too hot.
Phytotoxicity symptoms vary significantly between different crops and substances. However, the symptoms will usually include:
A rapid, sweeping change to most plants in the field in the form of deformed or distorted plant parts (especially newer foliage) and necrosis usually seen on the tips or margins of leaves.
No hay medidas de control; por lo tanto, el foco debe estar en la prevención.
Lea siempre las etiquetas de los productos y trabaje de acuerdo con lo que está escrito en la etiqueta del producto. Nunca mezcle dos sustancias a menos que esté escrito en la etiqueta del producto. Compruebe el producto químico / s en algunas plantas, luego espere un mínimo de 24 horas para controlar los efectos adversos antes de aplicarla a la mayoría de las plantas.
No rocíe cuando las temperaturas estén por encima de los 32 grados centígrados. Se prefiere pulverizar por la noche o temprano por la mañana. En general, la efectividad de los químicos disminuye cuando las temperaturas suben.
