An experiment was conducted during Rabi 2016-17 on mustard crop to test the bio- efficacy of insecticides namely Imidacloprid 17.8% SL, Acetamiprid 20% SP, Thiamethoxam 25% WG, NSKE 5%, Imidacloprid 17.8% SL + NSKE 5%, Acetamiprid 20% SP + NSKE 5%, Thiamethoxam 25 WG + NSKE 5% against mustard aphid. The results revealed that Imidacloprid 17.8 SL + NSKE 5% proved to the most effective in controlling the incidence of aphid followed by Thiamethoxam 25% WG + NSKE 5%. However, the NSKE 5% proved to be least effective. The highest net profit and incremental cost benefit ratio was observed from the plot treated with Imidacloprid 17.8% SL (Rs 19564/ha and 1:15.52) followed by Thiamethoxam 25% WG (Rs 18484/ha and 1:15.40). The maximum seed yield of 1621 kg/ha was recorded with the application of Imidacloprid 17.8 SL + NSKE 5% which was 581 kg/ha (35.84%) more than the control. Other treatments gave yield ranging from 1390-1606 kg/ha.
