Isoproturon at 1.0 kg. metoxuron at 1.6 kg and methabenzthiazuron 1.4 kg ha-' applied at 3-leaf stage provided more than 80% control of both susceptible (5) biotypcs (RI and H2) of P. milloI': however. these herbicides were ineffective against resistant (R) biotypes (H3, KRI and UPI) even at higher doses. Mon-48549 at 25 and 50 g, and Foe5043 at 300 and 600 g ha-' also did not control this weed satisfactorily. Performance of diclofop and metribuzin was also erratic against Rand S biotypes. Clodinafop at 60 g, fenoxaprop at 120 g, sulfosulfuron at 25 g and tralkoxydim at 350 g ha-' applied at 3-leaf stage resulted in 82-95% reduction in the dry weight of R as well as 5 biotypes of P. lIlilUJI: Metribuzin at 200 and 400 g ha", and Mon-48549 at 25 and 50 g ha-' caused 15 to 30% phytotoxicity to wheat. Metribuzin either alone or in mixture caused phytotoxicity to wheat crop without adding to weed control efficiency (WCE).
