Overcoming triclopyr confusion: safety, efficacy, and selectivity issues for applicators




Triclopyr is an auxin type herbicide that is widely used for invasive plant control in aquatic and upland systems. Historically, there have been two formulations, an ester and an amine, which have generally separate but occasionally overlapping use patterns. This has resulted in confusion among many land managers on what triclopyr formulation to use. Recent advances in triclopyr technology may exacerbate this issue as two additional triclopyr formulations, an acid and a choline have become available. This talk will help land managers overcome triclopyr formulation confusion and provide clear technical specifications on the similarities, differences, and label use patterns of the four formulations.
