Abstract: Tomato fruits are considerably affected by array of insect pests infesting at different stages of crop growth. Among the factors responsible for low yield of tomato, insect pests are major one. The present experiments entitled was carried out at Students’ Instructional Farm, Acharya Deva University of Agriculture and Technology, Kumarganj, Ayodhya (UP) during rabi season 2020-21 to test the efficacy of certain combination insecticides against major insect pests. Among the efficacy of certain combination insecticides, the treatment Betacyfluthrin 8.49% + Imidacloprid 19.81% OD 400ml/ha was observed most effective against whitefly, Jassid and serpentine leaf miner, whereas Chlorpyriphos 50%+ Cypermethrin 5% EC 1000 ml/ha was least effective against whitefly, Profenofos 40%+Cypermethrin 4% EC 1250 ml/ha was found least effective against Jassid and Triazophos 35%+ Deltamethrin 1% EC 1000ml/ha was least effective against serpentine leaf miner. Chlorantraniliprole 10%+Lambda cyhalothrin 5% ZC 250 ml/ha was most effective and found Triazophos 35%+ Deltamehtrin 1% EC 100ml/ha least effective against larval population of H. armigera followed by Imidacloprid 40%+Fipronil 40% WG 500 g/ha, Imidacloprid 40%+Ethiprole 40% WG 500 g/ha. The maximum yield (203.41 q/ha) was recorded in Betacyfluthrin 8.49% +Imidacloprid 19.81% OD 400ml/ha and minimum yield was recorded in Triazophos 35%+ Deltramethrin 1% EC 1000ml/ha (163.17 q/ha). The benefit cost- ratio 1:19.31 was recorded highest in Betacyfluthrin 8.49%+Imidacloprid 19.81% OD 400 ml/ha and lowest 1:3.12 in Imidacloprid 40%+Ethiprole 40% WG 500 g/ha. In comparison to traditional pesticides, these combination insecticides are a newer more efficient against the major pest of tomato at lower doses.
