Fatty alcohols turn smaller suckers brown soon after application. Leaf axils may also be burned by high concentrations of the chemical. Occasionally, buds of young plants may be killed. There may be contact-type burns on the tender, upper leaves. Damage is usually minor, but can be more severe if the concentration of the chemical is excessive or if application is made to wilted plants. Usually there will be burns along the edge or other portions of the leaf where the spray material collects. Leaf drop may occur at the lower part of the stalk if burn in the leaf axil is substantial, leaves are large, humidity is high, and certain disease organisms are present. Excessive nitrogen fertilizer contributes to these conditions.
