An experiment was conducted for two consecutive years during rabi season of 2014-15 and 2015-16 to manage the onion thrips using three treatment modules viz., M1- IPM module, M2- Farmers’ practice and M3-Untreated control. It has been observed that the IPM module was the best in achieving the maximum leaf growth and bulb yield in both the years (2014-15 and 2015-16) followed by farmers’ practice module. Adoption of IPM module (comprised of wheat and maize as barrier crops, seed treatment with imidacloprid 70WS and spraying of Beauveria bassiana 10 SC and spinosad 45SC at ETL) kept the plant less infested by the T. tabaci. An avoidable yield loss of onion bulb due to infestation of T. tabaci was estimated as 18.98%. The incremental benefit cost ratio (IBCR) was found more in IPM module than the farmers’ practice module. The maximum return per rupee investment for managing thrips in rabi onion was observed with IPM module being, Rs. 6.65.
