Bio-efficacy of Metribuzin and Prometryn in Wheat

Metribuzin (200, 250 and 300 g ha−1) provided effective control of P minor and other weeds in wheat. Its higher doses were phytotoxic to wheat. The lower dose was also phytotoxic but at lower degree. Prometryn had poor weed control and high phytotoxicity on wheat. None of the doses of metribuzin yielded at par with isoproturon at 1.0 kg ha−1, sulfosulfuron at 25 g ha−1 and weed-free.
