Wheat ,Weeds, Pendimethalin, Clodinafop, 2,4-D amine, Metsulfuron- methyl

Experimental site constituted by monocot weeds viz., Brachiaria spp. Echinochloa colonam L. Cav. dicot weeds viz., Amaranthus viridis, Digeria arvensis, Chenopodium album and Euphorbia hirta L. and sedges viz., Cyperus rotundus L. Integration of pendimethalin as pre-emergence (PE) with clodinafop, metsulfuron-methyl and 2,4-D amine salt post emergence with or without hand weeding proved effective in reducing weed density and dry weight of weeds. Significantly the higher yield attributing characters were recorded under weed free, closely followed by pendimethalin 0.9 kg/ha as pre emergence followed by one hand weeding at 35-40 DAS. The maximum net return was obtained under pendimethalin 0.9 kg/ha as pre-emergence + 1 HW at 35-40 DAS and which was closely followed by pendimethalin 0.9 kg/ha PE + clodinafop 60 g/ha as post emergence at 35-40 DAS.
