Abstract
Now a dayâs herbicides are important tool for weed management in wheat crop. As weeds develop resistance against herbicide, cause the serious threat to wheat growers. There is urgent need to find out the new herbicide mixture to control the weeds successfully. A research was conducted in complete randomized block design having eight herbicide mixture Sulfosulfuron (SUL) + Carfentrazone [25+20], SUL+ (Halauxifenmethyl + Florasulam) (HAL+FLO) [25+12.76], SUL+ Metsulfuron (MET) [25+4], Clodinofop (CP) + (HAL+FLO)* [60+12.76], SUL+ Pyroxsulam (PYR) [25+18], CLO+PYR [60+18], CLO+MET [60+4] and Mesosulfuron + Iodosulfuron (MES+IOD) [12+2.4] with hand weeding (20 & 40 DAS) and weedy check plot at Agricultural research farm, Banaras Hindu University in Rabi season of 2020-21. All the herbicide mixture recorded similar density of grassy and broad leaf weeds and dry weight of grassy weeds. However, SUL+CAR [25+20] recorded lowest dry weight of broad leaf weeds with highest weed control efficiency, weed control index and crop resistance index. All herbicide mixture recorded statistically similar grain yield.
