Field experiments were conducted in 1995 through 1997 in south and west Texas to evaluate diclosulam [N-(2,6-dichlorophenyl)-5-ethoxy-7-fluoro(1,2,4)-triazolo(1,5c)-pyrimidine-2-sulfonamide] for weed control in peanut. Diclosulam applied preplant incorporated at 0.01 kg ai/ha in combination with ethalfluralin at 0.84 kg ai/ha controlled Texas panicum, Palmer amaranth, morningglory species, and golden crownbeard at least 95% and devil's-claw 91%. When diclosulam rates were increased to 0.02 kg/ha, yellow and purple nutsedge were controlled at least 89% and 72%, respectively. Diclosulam applied postemergence (POST) provided erratic yellow nutsedge control.
