Abstract: The present investigation was carried out to study the field efficacy of insecticides against pod borer, Maruca vitrata Geyer infesting lablab bean. A statistically designed field experiment was conducted with Randomized Block Design with three replications and nine treatments during Rabi season of 2017-18 and 2018-19 at Botany farm, College of Agriculture, Dapoli. The results on pooled data of both of years, the overall mean per cent pod damage five plants-1 of all observations revealed that the treatment T1 (Spinosad 45 SC) was significantly superior over rest of the treatments by recording 4.20 overall mean per cent pod damage five plants-1. The treatment T1 (Spinosad 45 SC) was at par with T8 (Emamectin benzoate 5 SG) recorded 5.13 per cent pod damage five plants-1. The next best treatment T2 (Azadirachtin 10000 ppm) which was at par with treatments T3 (Deltamethrin 2.8 EC) and T4 (Malathion 50 EC) recorded 6.90, 8.21 and 8.36 per cent pod damage five plant-1, respectively. Whereas, the next treatments T5 (Beauveria bassiana), T7 (Metarrhizium anisopliae) and T6 (Verticillium lecanii) which were at par with each other and recorded (11.41%, 12.03% and 12.70%) pod damage five plants-1, respectively. The maximum (33.25%) pod damage five plants-1 was recorded in treatment T9 (Control water spray).
