Triclopyr


Triclopyr is an organic compound in the pyridine group that is used as a systemic foliar herbicide and fungicide.

Uses

Triclopyr is used to control broadleaf weeds while leaving grasses and conifers unaffected or to control rust diseases on crops.
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. It is sold under the trade names Turflon, Weed-B-Gon, and Brush-B-Gon 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 It is a major ingredient in Confront, which was withdrawn from most uses due to concerns about compost contamination from the other major ingredient, clopyralid.

Environmental effects

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 and quail. It has been found non-toxic to bees and very slightly toxic to fish.
