Abstract
The present study was conducted during March to July 2021 in the experimental field of the Department of Entomology of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to evaluate the effect of some biorational insecticides on pod borer infestation in yard long bean. The study was laid out by Randomized Complete Block Design (RCBD) with 3 replications. The treatment comprised Vermitec 1.8 EC (Abamectin) @ 1.0 ml/L, Tracer 45 SC (Spinosad) @ 0.4 g/L, Bio-Action 1.5 SL (Matrine) @ 1.5 ml/L of water, Ecomec 1.8 EC (Azadiractin) @ 1.5 ml/L and Phytoclean (Potassium salt of fatty acid 40%) @ 1.5 ml/L of water at 15 days interval along with an untreated control for comparison. The study revealed that the lowest rate of inflorescence infestation, the highest reduction of flower shedding, lowest rate of pod infestation by pod borer as well as the highest fruit sets and marketable yield (10.7±0.3 MT/ha) was recorded with the bio-rational management approach comprising 3 sprays of Tracer 45 SC (Spinosad) @ 0.4 g/L of water
