Sixteen weed control treatments viz. pinoxaden (40 g ha-1), isoproturon (1250 g ha-1) alone,isoproturon + pinoxaden (1000 + 40 g ha-1), isoproturon + pinoxaden (750 + 30 g ha-1), isoproturon +2,4-D (1000 + 500 g ha-1), isoproturon + metsulfuron-methyl (1000 + 4 g ha-1), pinoxaden + 2,4-D (40+ 1000 g ha-1), pinoxaden + metsulfuron-methyl (40 + 4 g ha-1), isoproturon fb pinoxaden (1000 fb 40g ha-1), isoproturon fb pinoxaden (750 fb 30 g ha-1), pinoxaden fb isoproturon (40 fb 1000 g ha-1),pinoxaden fb isoproturon (30 fb 750 g ha-1), pinoxaden fb 2,4-D (40 fb 1000 g ha-1), pinoxaden fbmetsulfuron-methyl (40 fb 4 g ha-1), hand weeding (30 & 60 DAS) and weedy check were evaluated forthe control of mixed weed flora in wheat at Palampur. Soil of the test site was silty clay loam in texture,acidic in reaction, medium in available nitrogen, available phosphorus and available potassium status.Avenaludoviciana and Phalaris minor were the major weeds constituting 35 and 25.1 per cent,respectively, of total weed flora at 90 DAS. The broad-leaf weeds (Anagallis arvensis, Vicia sativa andCoronopus didymus) as a whole constituted 28.6 per cent of total weed flora. Results of the studyrevealed that pinoxaden fb metsulfuron methyl (40 fb 4 g ha-1) and pinoxaden + metsulfuron methyl(40 + 4 g ha-1) were superir to hand weeding and resulted in significantly lower population of Avenaludoviciana, Phalaris minor, Lolium temulentum, Anagallis arvensis, Vicia sativa and Coronopusdidymus. Sequential application of pinoxaden fb metsulfuron methyl (40 fb 4 g ha-1) resulted insignificantly higher grain yield, net returns (47489 ` ha-1) and net returns per rupee invested (1.97).However, pinoxaden + metsulfuron methyl (40 + 4 g ha-1) was comparable to pinoxaden fbmetsulfuron methyl (40 fb 4 g ha-1) in increasing the grain yield of wheat
