Ten different IPM modules were evaluated against mustard aphid, Lipaphis erysimi (Kalt.). The treatment schedule comprising two sprays of imidacloprid 17.8 SL (0.005%) caused maximum reduction of aphid population with the cumulative mean of 77.29 and 79.11% after 3 days of spray, during 1st and 2nd years, respectively. It was followed by the treatment thiamethoxam 25 WG @ 0.005%. The maximum seed yield (3,899.33 and 3,949.33 g/plot) was obtained in the treatment schedule consisting of two sprays of imidacloprid 17.8 SL @ 0.005%. The maximum net return was also recorded in the same treatment (? 15,676) with highest benefit: cost ratio of 1.32.
