Abstract

The study was carried out at central research farm in rabi season at Sam Higginbottom University of Agriculture Technology and Sciences. The efficacy of treatments was measured in terms of the reduction in aphid population. Imidacloprid 17.8 SL exhibited the highest population reduction (95.210), followed by Dimethoate 30 EC (82.887), Acetamiprid 20 SP (69.350), Neem oil 5% (48.767), N.S.K.E. (42.040), Verticillium lecanii 1.15 WP (39.95), Beauveria bassiana 1.15 WP (30.707), with the untreated plot showing the minimum reduction. The cost-benefit analysis of treatments revealed that. Imidacloprid 17.8 SL demonstrated the highest return (1:5.23), followed by Dimethoate 30 EC (1:4.26), Acetamiprid 20 SP (1:4.16), Neem oil 5% (1:3.67), N.S.K.E (1:3.45), Verticillium lecanii (1:2.77), and Beauveria bassiana (1:2.61). The control plot yielded the lowest return (1:1.56).
