Abstract: The study on Seasonal Occurrence and Management of Tobacco Leaf Eating caterpillar Spodoptera litura (Fab.) on Soybean was carried out during Kharif season 2018-19 under field condition of the Entomology Section, College of Agriculture Nagpur. Seasonal incidence of S. litura initiated during 30^th standard week (0.20 larvae/mrl) gradually attained maximum (1.60 larvae/mrl) during 35^th standard week. Population was decreased from 36^th standard week onwards. Overall spinosad 45 SC @ 0.01% and fenvalerate 20 EC @ 0.01% was found statistically most significant in controlling the S. litura larval populations on soybean at 3^rd, 7^th and 14^thdays after treatment. As regards to soybean grain yield, the application of spinosad 45 SC @ 0.01% and fenvalerate 20 EC @ 0.01% were found to be most effective treatments recording higher yield of 13.46 q/ha, 12.82 q/ha, respectively.
