| Summary: | The experiment had been carried out at the Students' Instructional Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), during the Rabi season in 2021-22. Imidacloprid 40% + Fipronil 40% at 500g/ha proved to be the best performing insecticidal treatment when coupled with botanicals in decreasing aphids (Aphis craccivora), whitefly (Bemisia tabaci), leaf miner (Liriomyza trifolli), and pod borer (Helicoverpa armigera). On the other hand, the combination of Emamectin Benzoate + Ipomoea carnea leaf extract 5g a.i./ha + 5% was the least effective against these pests, while Imidacloprid + Ipomoea carnea extract 25g a.i./ha + 5% showed moderate efficiency against pod borer larval populations. Imidacloprid 40% + Fipronil 40% 500g/ha delivered the best yield (8.21 q/ha), while the lowest yield (6.64 q/ha) was achieved in Imidacloprid + NSKE 25g a.i.+5%. The insecticide treatment Imidacloprid 40% + Fipronil 40% at 500g/ha was the most effective in controlling aphids, whitefly, leaf miner and pod borer as well as in maximizing yield and can be incorporated in the pest management programme in French Bean.
