This report represents results from a project for research to develop and implement new treatment mixtures for control of problem brush, trees and other woody species and herbicide-resistant weeds along Indiana roadsides. An environmentally safe mixture of trichlopyr (Galon Herbicide) and ammonium nitrate for one application control of deciduous roadside vegetation was developed. Also discovered and developed was a new, environmentally safe and effective TR series of additives that enhance the action of the auxin herbicides (trichlopyr, 2,4-D, picloram) for inclusion in both the brush control mixtures and control of milkweed, Canada thistle, bindweed, ground cherry and other perennial, herbicide-resistant roadside weeds.
