Descriptor:
Damage
Description:
Fatty alcohols (contact sucker control chemicals) turn small suckers brown shortly after application. Leaf axils may be burned by high concentrations of these alcohols. Buds of young plants may be killed. Leaf burn may be observed, particularly along the outer edge of tender upper leaves. Damage from these burns is usually minor, but it can be severe if the concentration of the chemical is excessive or the application is made to wilted plants. Leaf drop, shown in above photo, may occur at the bottom of the plant if the leaf axils have been severely burned.
