摘要

Metribuzin alone 210 g/ha resulted in significantly lower population of Phalaris minor than alone application of clodinafop 60 g/ha, pinoxaden 40 g/ha and sulfosulfuron 25 g/ha. Application of sulfosulfuron + metsulfuron 32 g/ha and 25 + 210 g/ha resulted in significantly lower population of P. minor and C. album, respectively. Sulfosulfuron + metsulfuron 32 g/ha resulted in 89.2% WCE which was at par with sulfosuifuron + metribuzin 25 + 210 g/ha. Weed control treatments produced significantly highergrain yield as compared to weedy check. Sulfosuifuron 25 g/ha being significantly superior to alone applicafion of metribuzin 210 g/ha, clodinafop 60 g/ha and pinoxaden 40 g/ha produced higher wheat grain yield, which was evident from the higher WCE ascompared to other herbicides. Ready-mix application of sulfosuifuron + metsulfuron at 32 g/ha produced the highest grain yield (6.42 t/ha) among different herbicide treatments but it was statistically at par with weed free.
