This research was initiated to discover more effective, more efficient, and safer methods of controlling roadside vegetation. Specifically, the research was designed to find the safest way to control weeds near susceptible crops and to find the best herbicide(s) to selectively control 'hard-to-kill' undesirable vegetation. All promising herbicides and thickening agents on the market at the time the research was initiated were evaluated. The equivalent rates of several soil sterilant herbicides were established. The effectiveness of growth retardants were studied. The research can be readily applied to areas having plant populations and growing conditions similar to Missouri.
