Abstract: Study on bio-efficacy of different insecticides and against fall armyworm Spodoptera frugiperda of sorghum was conducted at Department of Agricultural Entomology, College of Agriculture, Latur (Maharashtra) during rabi, 2021. All the insecticides were found to be significantly superior in recording minimum number of S. frugiperda over untreated control. Among different insecticides, the incidence of fall armyworm S. frugiperda on sorghum plant was observed to be significantly decreased in the plots sprayed with Thiamethoxam 30 FS seed treatment 10 ml/kg f.b. Emamectin Benzoate 5% SG 4 g/10 l. The present investigation revealed better response of Imidacloprid 48% FS seed treatment 5 ml/kg f.b. Emamectin Benzoate 5% SG 4 g/10 l recorded highest grain yield (32.19 q per ha) which was followed by Imidacloprid 48% FS seed treatment 5 ml/kg f.b. Chlorantraniliprole-18.5% SC 3 ml/10 l (31.01 q per ha) and Thiamethoxam 30 FS seed treatment 10 ml/kg f.b. Emamectin Benzoate 5% SG 4g/10 l (30.67 q per ha) to pest control which also reflected with higher grain yield. However, Imidacloprid 48% FS (seed treatment) documented most economic treatment with highest ICBR (1:25.1).
