The present investigation was carried out to study the efficacy of different insecticides against lablab bean aphid, Aphis craccivora Koch. 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 with a view to test the relative efficacy of some insecticides for the control of aphid.
The results on pooled data of both of years, the overall mean aphid population of all observations revealed that the insecticidal treatments viz., treatment T4 (Malathion 50 EC) was significantly superior over rest of the treatments by recording 2.30 overall mean aphids three leaves-1 plant-1. The treatment T4 (Malathion 50 EC) was at par with treatments T3 (Deltamethrin 2.8 EC), T1 (Spinosad 45 SC) and T8 (Emamectin benzoate 5 SG) recorded with 2.83, 3.94 and 4.10 mean aphid population, respectively. The next best treatment T2 (Azadirachtin 10000 ppm) was recorded 6.20 mean aphids three leaves-1 plant-1. The treatment T2 (Azadirachtin 10000 ppm) which was at par with treatments T6 (Verticillium lecanii), T5 (Beauveria bassiana) and T7 (Metarrhizium anisopliae) recorded 7.28, 8.13 and 8.21 mean aphid population, respectively. The maximum 31.91 aphids three leaves-1 plant-1 was recorded in treatment T9 (Control water spray).
