Field Evaluation of New Molecules for the Control of Spodoptera litura (Fabricius) on Groundnut

Field experiment was conducted to evaluate some new molecules against Spodoptera litura (Fabricus) in groundnut. The application of spinosad 0.018% was found to be superior in suppression of larval population of S. litura and was on par with emamectin benzoate and thiodicarb. The highest pod yield (1983 kg/ha) recorded with the treatment of spinosad was on par with all the insecticides evaluated whereas bio-agents stood at second position. Chlorpyriphos recorded highest cost benefit ratio (1: 8.11) followed by quinalphos (1: 6.11) and emamectin benzoate (1: 5.3).
