In trials in 1986-87, weed control from herbicides applied after transplanting was assessed in C. annuum cv. Yolo Wonder produced for processing. Diethatyl (Antor) at 2.2 kg/ha and diethatyl + diphenamid (Enide) at 3.4 + 3.7 kg caused noticeable crop injury at 4 weeks after application in one year. No injury was apparent at 11 weeks in either year from any of the treatments. Best weed control was provided by clomazone (Command) at 1.7 kg, trifluralin (Treflan) at 1.1 kg incorporated pre-transplanting and followed by napropamide (Devrinol) at 1.1 kg or from 2 applications of diethatyl at 2.2 kg. Chemical treatments resulted in up to 90% higher yields than those obtained on cultivated controls. Yields did not vary significantly between herbicide treatments
