A field experiment was conducted during the kharif season of 2000 to study the effect of different herbicides on weed control in soyabean (Bragg). It was observed that Imazethapyr (Pursuit) at 100 g ai/hectare gave the best control of sedges and broad leaved weeds with the lowest weed dry matter of 1.3 and 4.9 g/m2 at 40 DAS and Dimethenamid-P (Frontier) at 1100 g ai/hectare effected the best grassy weed control with the lowest weed dry matter (1 g/m2) at 40 DAS. The highest over all WCE (78.8%) at 40 DAS recorded with the treatment Imazethapyr (100 g a.i/hectare). Tank mix of Bentazon + Dimethenamid-P + ammonium nitrate showed phytotoxicity and gave poor yield (1134 kg/bectare). WCE and soyabean seed yield were found to be positively correlated and Imazethapyr at 100 g ai/hectare produced the highest seed yield (2172 kg/hectare) followed by Fluchloralin at 960 g a.i /hectare giving 2132 kg/hectare of seed yield. The lowest seed yield (986 kg/hectare) was obtained with the unweeded control treatment.
