Abstract: A field experiment was carried out in medium deep black soil in farmer’s field of Mugali village, Ron taluka in Gadag district during kharif 2011 under rainfed condition to find out effect of pre and post emergence herbicides for weed management in chilli + onion intercropping system. The experiment was laid out in a randomized block design with three replications. The experiment consisted of 8 treatments involving five pre emergence herbicides viz., Pendimethalin @ 1.0 kg a.i/ha, Butachlor @ 1.0 kg a.i/ha, Oxadiargyl @ 90 g a.i/ha and Alachlor @ 1.0 kg a.i/ha, Alachlor @ 1.50 kg a.i/ha and One post emergence herbicide Oxyfluorfen 0.15 kg a.i/ha (45 DAS) and compared with Farmers’ practice (3 HW at 20 days interval), Weed free and Weedy check. Application of Pendimethalin @ 1 kg/ha fb Oxyfluorfen @ 0.15 kg/ha + hand weeding recorded higher dry chilli and onion bulb yield and also recorded lower total weed count, total weed dry weight and lower weed index compared to farmers’ practice.
