The maximum reduction of weed population, weed dry weight and the highest weed control efficiency vis-a-vis crop yield, and maximum benefit: cost ratio were obtained in the treatment receiving quizalofop-p-ethyl 50 g a.i. ha-1 at 21 day after emergence (DAE) + hand weeding (HW) at 28 DAE. This was closely followed by the treatment with quizalofop-p-ethyl 50 g a.i. ha-1 at 14 DAE + HW at 21 DAE. Weedy check treatment produced lowest yield of mungbean.
