Abstract
Johnsongrass (Sorghum halepense L.) presents a serious problem in the production of corn and soybeans in Kentucky.
Various rates of the thiocarbamates, dinitroanilines, carbamates, amides, ureas, and triazines were used in association with the crops corn (Zea mays L.) and soybeans (Glycine max L.) to determine the degree of suppression on rhizomatous johnsongrass infesting the previously named crops.
Suppression was determined by selecting areas within each treated plot, counting the number of culms, then harvesting johnsongrass rhizomes. Dry weights of rhizomes were then determined as a measure of rhizome suppression.
Results show that of the various herbicides and rates used, none were significantly different in their degree of rhizome suppression.
