Triclopyr is effective on woody plants and is used for brush control in the right of way and defoliation of wooded areas. In the USA it is sold under the trade names Garlon and Remedy, and in the UK as SBK Brushwood Killer.
It is also used for broadleaf weeds, particularly Creeping Charlie (Glechoma hederacea). It is sold under the trade names Turflon, Weed-B-Gon (purple label), and Brush-B-Gon ("Poison Ivy Killer") for these purposes. It is a major ingredient in Confront, which was withdrawn from most uses due to concerns about compost contamination from the other major ingredient, clopyralid.
Triclopyr breaks down in soil with a half-life of between 30 and 90 days. Triclopyr degrades rapidly in water. It remains active in decaying vegetation for about 3 months.
The compound is slightly toxic to ducks (LD50 = 1698 mg/kg) and quail (LD50 = 3000 mg/kg). It has been found non-toxic to bees and very slightly toxic to fish (Rainbow trout LC50 (96 hrs.) = 117 ppm).
