Three formulations of triclopyr, the ester, the amine, and amine plus organosilicone surfactant, were screened for contact phytotoxicity to the adaxial and abaxial surfaces of leaves of sweetgum, red maple and red oak, using a single concentration of herbicide and droplet size. Radiolabelled triclopyr was used to determine uptake and translocation. It was found that the amine formulation plus organosilicone surfactant, had uptake and translocation performance similar to that demonstrated with
