Abstract
Forty-four herbicides were used alone and in various combinations as soil sterilant treatments on roadsides. Usually three rates of application were employed, the highest rate surpassing the recommended label rate. Applications in June and August were equally effective and were superior to October treatments.|Although many of the treatments, especially mixtures of herbicides, were effective soil sterilants, they have very limited use on roadsides. In every case treatments giving acceptable soil sterilization moved downslope from the point of application, and the resultant bare soil was subject to erosion. This adverse effect could not be overcome with spray volumes up to 400 gal/A nor with asphalt emulsion as a carrier or as a cap over the treated area. Greater movement downslope was experienced with granular forms than with the same material applied as sprays. Higher rates of the same herbicide moved more than lower rates.
