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).
*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.
