A field experiment was conducted during kharif, 2013 to study the efficacy of sequential application of pre and post-emergent herbicides on weed control in green gram grown under rainfed condition. Results indicated that sequential treatments were found superior to individual application with respect to weed control. Among the sequential treatments, pre emergent application of pendimethalin @ 1.0 kg ha-1 followed by imazethapyr @ 75 g ha-1 at 20 days after sowing (DAS) significantly reduced weed growth and recorded higher seed yield (1110 kg ha-1), net monetary returns (` 27345 ha-1) and BC ratio (3.44:1) and was on par with other sequential treatments viz., pendimethalin fb post-emergent application of fenoxyprop-p-ethyl or one hand weeding (HW) and one intercultivation (IC), pre-emergent application of alachlor fb post-emergent application of either imazethapyr or one HW and one IC, tank mix application of  alachlor + pendimethalin as pre-emergence fb one HW and one IC and farmer’s practice. Uncontrolled weed growth caused 57.4 per cent reduction in seed yield of green gram
