Bioefficacy of certain novel insecticides and some biopesticides for managing bean pod borer, Maruca Vitrata Geyer

Abstract\nBean pod borer, Maruca vitrata Geyer is a key pest of bean causing up to 80 percent yield loss. The present study was conducted at the Entomology Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh during October 2017 to March 2018 to evaluate the bioefficacy of certain novel insecticides and some biopesticides for managing bean pod borer on BARI Shim-2. Treatments were evaluated based on different parameters viz. no of healthy and infested pod, percent pod infestation, and marketable pod yield (t/ha). The experiment was laid out in RCBD with 3 replications of each treatment. Eight treatments viz. T1: Cartap (Suntap 50 SP), T2: Flubendiamide, (Belt 24 WG), T3: Lufenuron (Heron 5EC), T4: B. bassiana, T5: Cypermethrin, T6: Spinosad (Libsen…
