Where is Triclopyr butoxyethyl ester used?

• Agriculture and forestry: control of broadleaf weeds, woody plants and brush species
• Forestry and vegetation management: suppression of competing hardwood species and invasive brush, allowing conifer regeneration without damaging grass understory
• Turf and pasture: elimination of broadleaf weeds
• Rights-of-way: long-term brush control along utility corridors, roadsides and pipeline easements where repeated mechanical clearing is cost-prohibitive
• Aquatic-adjacent environments: control of target species
• Oil-soluble ester formulations penetrate waxy or bark-covered target species.

Commercial specifications
