פגיעת קוטלי עשבייה

Herbicide injury occurs after plants come in contact with herbicides.

Herbicide injury 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 (seen on the tips or margins of leaves).

Reasons:

*Improper use: Applying off label brands, overdosing plants with chemicals, and applying concentrations that are too high.

*Splashes of sprayed applications and air drifts contaminate cultivated crops.

*Substances in the soil accumulate past a safe threshold.
