A field experiment was directed during Rabi season 2018-2019 at experimental farm of Doon (P.G.) College of Agriculture Science and Technology, Selaqui, Dehradun (Uttarakhand) using pre-and post-emergence herbicides combined with Hand Weeding for successfully controlling of weeds, their result on yield and production economics on Wheat (Triticum asetivum L.) variety used ‘Unnat PBW-343’. The dominant weed species present in field were Phalaris minor, Cynodon dactylon (L.) amongst dicot weeds like as Chenopodium album, Coronopus didymus, Fumaria parviflor, Medicago denticulate, Malva praviflora Vicia, Sativa Rumex debtatus, Sisymbrium irio among monocot, were observed during growing period. Lowest weed dry weight was observed in hand weeding at 30 and 60 Days after sowing. Higher Weed control efficiency up to (86.31 %) was recorded by Hand weeding at 30 and 60 Days after sowing.  The treatment pendimethalin fb Sulfosulfuron @ 1 + 0.018 kg a.i.ha-1 P.E at 2 DAS and PoE at 30 DAS (T6) recorded greater yield attributes and seed and Stover yield (2540 kg/ha and 2668 kg/ha) and maximum net monetary return (Rs 36250) and Benefit: Cost ratio and 1.86.
