Abstract

Field experiment was conducted to evaluate the efficacy of insecticides against mustard aphid Lipaphis erysimi (Kalt.) on mustard. Significant reduction in population was obtained with imidacloprid 17.8 SL followed by acetamiprid 20 SP and thiamethoxam 25 WG. Thus, reduction in aphid population was to an extent of 65.83% with imidacloprid 17.8 SL followed by thiamethoxam 25 WG and acetamiprid 20 SP. The maximum yield was obtained with acetamiprid followed by imidacloprid and thiamethoxam. NSKE 5% was found to be the least effective. Maximum benefit/cost ratio (5.65: 1) was obtained with acetamiprid 20 SP.
