Abstract: Field experiment was conducted in the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during 2009 kharif season to evaluate the efficacy of insecticides for increasing yield of country bean by protecting pod damage by bean pod borers. The spray plots gave significantly higher yield than the control plots. Among the insecticides, Neem oil, Fenitrothion50 EC and Emamectin benzoate 5 SG performed best by reducing 59.46, 51.35 & 45.95% infested pod production respectively. For marketable pod yield, Deltramethrin 2.5 EC, Fenotrothion 50 EC and Curtap 50 SP performed best by producing 5.78, 5.48 & 5.39 ton/hectate at the same time increasing 46.70, 38.58 & 36.80 % marketable pod yield over control respectively. Thus for gross yield, Deltramethrin 2.5 EC, Fenitrothion 50 EC & Curtap 50 SP performed best by producing 6.11, 5.65 & 5.61 ton/ha as well as increasing 41.76, 31.09 & 30.16 % gross pod production. Therefore, Deltramethrin 2.5 EC, Fenitrothion 50 EC & Curtap 50 SP can be recommended for successful country bean cultivation with more production during kharif season.
