Common NamePicloram
ClassSmall Molecule
DescriptionPicloram is a persistent systemic herbicide used for general woody plant control and a broad-leaved weeds on non-crop and utility areas. It also controls a wide range of broad-leaved weeds, but most grasses are resistant. A chlorinated derivative of picolinic acid, picloram is in the pyridine family of herbicides. It is systemically absorbed by roots and leaves and translocated.
