Biochemistry Synthetic auxin (acting like indolylacetic acid).  Mode of action Selective systemic herbicide, rapidly absorbed by the foliage and roots, with translocation throughout the plant, accumulating in meristematic tissue. Induces auxin-type responses in susceptible species (mainly broad-leaved weeds, grass weeds being unaffected at normal application rates). 

Uses Control of woody plants and many broad-leaved weeds (e.g. nettles, docks, brambles, gorse, broom) in grassland, uncultivated land, industrial areas, coniferous forests, plantation crops, and rice fields. In plantation crops (oil palm, rubber) at 125-250 g a.e./ha for covercrop maintenance, and at 0.72-1.0 kg a.e./ha to control Eupatorium odoratum and other problem plants; in pastures at 1-2 kg/ha to control annual and perennial herbaceous weeds, and at 2-4 kg/ha against Rubus spp. and other woody plants; in forestry at 4-8 kg/ha for site preparation, and at 1.5-2.0 kg/ha for conifer release; for industrial sites at 2-8 kg/ha; in rangeland at 0.24-1.0 kg/ha.  Phytotoxicity Clovers are sensitive, as also are larch, lodgepole pine, ornamentals, and edible crops.
