An experiment comprising seven post emergence treatments viz., Sulfosulfuron 75 WP @ 25 g a. i. ha-1, Sulfosulfuron 75 WP + Metsulfuron 5 WP @ 32 g a. i. ha-1, Fenoxaprop Methyl 10 WP @100 g a. i. ha-1, Pinoxaden 5EC @ 50 g a. i. ha-1, Vesta (Clodinofop propargyl 15% + Metsulfuron 5 wp @ 60 g a. i. ha-1), Halauxifen Methyl 6.96% WW + Pyroxsulam 25% WW/WG @ 19.71 g a. i. ha-1 and Broadway (Carfentrazone ethyl 20% + Sulfosulfuron 25% WG @ 100 g a. i. ha-1) at 30-35 days after sowing along with un-weeded control was conducted in randomized block design with 3 replications at Crop Research Farm, Nawabganj, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (Uttar Pradesh) in wheat cv. K1006 during Rabi 2019-20. The most successful method for controlling a wide range of broad-leaved weeds, such as Chenopodium album, Convolvulus arvensis, Melilotus indica, Anagallis arvensis, Rumex dentatus, Coronopus didymus, etc., was to apply Broadway (Carfentrazone ethyl 20% + Sulfosulfuron 25% WG @ 100 g a. i. ha-1). For grassy weeds, such as Phalaris minor and Avena fatua, the most effective combination was Sulfosulfuron 75WP + Metsulfuron 5 WP @ 32 g a. i. ha-1. However, the maximum weed control efficiency was observed by Broadway (Carfentrazone ethyl 20% + Sulfosulfuron @ 25/WG @ 100 g a.i. ha-1) (87.35%), Halauxifen methyl 6.95% w/w + Pyroxsulam 25% w/w/WG @ 19.71g ha-1 (85.26%). This would ensure sustained productivity and profitability in wheat cultivation.
