Efficacy of post emergence herbicides on weed flora of soybean [Glycine max (L) Merrill]


Author(s): Jagdish Chandra Parmar, MD Vyas and Ghanshyam Jamliya

Abstract: The present study was conducted in rainfed condition on the field no 12 of the Research Farm, R.A.K. College of Agriculture, Sehore (M.P.), during kharif season of 2010. Result indicated that all the treated plots significantly reduced the weed dry weight over untreated control. Lowest weed dry weight, weed density and highest weed control efficiency (89.67%), weed competition index was recorded with Two hand weeding (at 30 and 45 DAS) followed by Post emergence application of imazamox + imazethapyr 70% WG @ 70 g/ha. Among post emergence herbicides application of imazamox + imazethapyr 70% WG @ 70 g/ha herbicides recorded maximum weed control efficiency of 77.67 per cent and were effective to control both monocots and dicots than other post emergence herbicides. Post emergence application of Fenoxyprop-ethyl 9% EC was effectively control the monocot weeds particularly Echinochloa colonum Link. and Sorghum helepense. Treatment two hand weedings recorded the highest value of seed yield followed by treatment imazamox + imazethapyr 70% WG @ 70 g/ha.
