 abstract = {Farmers’ participatory field trail was conducted in 33.18 ha representing rainfed cotton-growing region in Nanded district of the central zone, to evaluate the performance of Bt cotton hybrid MECH-162 under Integrated Pest Management (IPM), and to compare it with conventional cotton (CC) hybrids/varieties grown with and without IPM. There was significant reduction in bollworm incidence, particularly the American bollworm (Heliocoverpa armigera) and pink bollworm (Pectinophora gossypiella) and the damage caused by them to the fruiting bodies in Bt MECH-162 compared to CC with IPM. In Bt MECH-162, 11.5% of the fruiting bodies were damaged compared to 29.4% in CC with IPM. Maximum damage was observed in CC without IPM, where seven sprays of pesticides were made for control of insect pests in comparison to three on Bt MECH-162. Population of the sucking pests and two natural enemies monitored was also lower in Bt MECH-162 compared to CC. The latter without IPM recorded the lowest population of natural enemies. Seed cotton yield (12.4 q/ha), and net returns (Rs 16231/ha) were highest for Bt MECH-162. CC under IPM recorded an yield of 7.1 q/ha, and return of Rs 10507/ha. The results show that IPM in cotton was most effective with Bt MECH-162, and provided higher return though the initial seed cost for the farmers was higher.},
