The field experiment was conducted at Agricultural Research Station, Bailhongal, Karnataka, during 2010-11 and 2011-12 to study on the evaluation of novel insecticides for the management of Spodoptera litura (Fab.) infesting soybean. Results of the field experiments revealed that among the treatments flubendiamide 480 SC recorded the least larval population (0.42 larvae per meter row length) and it was significantly superior over other treatments. Indoxacarb 14.5 SC and spinosad 45 SC were found to be the next best treatments, which recorded 0.64 and 0.68 larvae per meter row length, respectively and were on par with each other, followed by rynaxypyr 20 SC,emamectin benzoate 5 SG which recorded 0.94 and 0.93 larvae per meter row length, respectively. Flubendiamide 480 SC provided consistent protection from defoliation to a soybean crop from S. litura.
