Herbicides are normally separated into two general categories:
selective and non-selective herbicides.
Herbicide drift can occur with any herbicide.
Leaf chlorosis, or yellowing of foliage, with cupping and curling, is a
common symptom of herbicide injury in plants. Leaf stems may twist or spiral.
Foliar spotting may be a result of herbicide spray drift. Overall necrosis,
or death of tissue, is caused by a number of products and can occur in advanced
stages of herbicide poisoning.
Read the label and avoid drift by only applying herbicides on calm days.
Avoid water contamination.
