ClassSmall Molecule
Description
Triclopyr is a systemic, foliar herbicide in the pyridine group for perennial broad-leaved and woody weed control on uncultivated areas, grassland, plantations and rice fields. It is used to control broadleaf weeds while leaving grasses and conifers unaffected. It is selective, systemic, and absorbed through roots and foliage. It is a synthetic auxin.
