The new postemergence herbicide nicosulfuron (Accent) makes integrated management of johnsongrass, Sorghum halepense (L.), in field corn economically feasible and environmentally sound. In a study of its effect on johnsongrass and field corn in Yolo and Sacramento counties, nicosulfuron provided control of johnsongrass at all growth stages. However, early treatments resulted in the highest corn yields.
