Chemical control and avoidable yield losses of Pigeon pea due to insect pests

Field investigation was carried out on chemical control of pigeon pea pod borers and podfly with insecticides resulted that imidacloprid and acetamiprid showed minimum pod infestation during two years. Rests of the insecticides were significantly superior over the control plots except dhanuvit. Acetamiprid treated plots also gave better results after imidacloprid followed by dimethoate 25 EC, carbosulfan 25 EC, indoxacarb 14.5 SL and methomyl 40 SP. The maximum grain yield and avoidable losses and additional grain yield (18.51 qha⁻¹, 42.7% & 7.91 qha⁻¹) was also recorded in imidacloprid treated plots over control plots.
