Studied on bio-efficacy of nine insecticide against aphid Lipaphis erysimi (Kalt.) on mustard. Insecticide used in experiment were flonicamid 50% WDG, imidacloprid 40% + fipronil 40% w/w 80% WG, dinotefuran 20% SG, clothianidin 50% WDG, fipronil 5% SC, thiamethoxam 12.6% + lambda cyhalothrin 9.50% @ 0.015%, thiacloprid 48% SC, dimethoate 30% EC and imidacloprid 17.8% SL. The aphid index data was recorded before 1 day, after 3, 5, 7, and 10 day of both spray.The lowest aphid index was noticed in plots treated with thiamethoxam 12.6% + lambda cyhalothrin 9.50% @ 0.015% and it was at par with flonicamid 0.002% and imidacloprid 0.005%. The orderof effectiveness of synthetic insecticides was thiamethoxam 12.6% + lambda cyhalothrin 9.50% @ 0.015% > flonicamid 50%WDG 0.002% > imidacloprid 17.8% SL 0.005% > clothianidin 50% WDG 0.003% > dimethoate 30% EC 0.03% > thiacloprid 48% SC 0.024%> imidacloprid 40% + fipronil 40% w/w 80% WG 0.03% > fipronil 5% SC 0.05% > dinotefuran 20% SG 0.008%. Considering the effectiveness yield and economics of insecticides imidacloprid 0.005%, dimethoate 0.03%, flonicamid 0.02%, thiamethoxam 12.6% + lambda cyhalothrin 9.50% @0.015%were found most effective and economical for control of aphid in mustard.
