Post-emergence application ofimazethapyr at 75 g ha-' reduced the population of Caesulia axillaris. Anatis monthulani and Ac~vpha indica significantly as compared to all pre- and rest ofthe post-emergence herbicides under investigation. Quizalofop-ethyl 5 EC at 50 g ha- ' was significantly effective against Cammelina benghalensis and Echinachlaa colona. The lowest weed biomass was recorded with two hand weedings 20 and 40 DASfollowed by imazethapyr at 75 g ha-' and quizalofop-ethyl 5 EC at 50 g ha- '. Two hand weedings (at 20 and 40 DAS) and imazethapyr at 75 gha-' were most appropriate treatments in tem1S of reduction in total weed density and increase in soybean yield.
