Field experiment was conducted during kharif season of 2019-20 on non-cultivated area available at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari entitled “Effect of Non selective herbicides on Cyperus rotundus in non-crop area”. Among the different weed management practices, application of Glyphosate 41% SL (W₁ and W₂) cent per cent ruined the density and dry weight of Cyperus rotundus dry weight at 15 DAA with negligible dry weight at 60 DAA. Moreover, effect was more pronounced with higher dose i.e. 3.0 kg/ha and combined with 2,4-D salt 58% SL 2.0 kg/ha (W₆). Further, ready mixed application of Glyphosate 41% + Oxyfluorfen 2.5% SC 2.0 kg/ha (W₅) detected significantly at par and reduced the dry weight of sedge weeds. On the basis of results obtained, Glyphosate 41% SL found much better as compared to other herbicides and crumbed the Cyperus rotundus hundred percent within fortnight and checked the resurgence for a month with negligible resurgence at 60 days of application. Thus, it is advised to apply Glyphosate 41% SL 2.0 kg/ha for effective and economic control of weeds in non-cropped land.
