Abstract

Glyphosate at rates found adequate (3.36 kg/ha) for orchard weed control is phytotoxic and possibly fatal to young apple trees if it is intercepted by the tree’s foliage in sufficient quantities. Its use appears safe, however, if precautions are used to avoid this contact. Following foliage absorption, the glyphosate is translocated to active growing points resulting in leaf attenuation and cupping and necrosis to leaves, terminals, and trunks.
