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.
