Selected Grass Killers on Johnsongrass in Cotton, Graham County

Abstract

Three gramicides, Poast, Fusilade and Assure, were sprayed on small plots of cotton infested with Johnsongrass. Nine days later, counts were made to determine the percent control achieved by the sprays. Control from all the materials was good, from 89.3 to 94 percent, but in all cases, a second application would be necessary to complete the job.
