Abstract
Among insect pests, lepidopteron defoliators viz., Helicoverpa armigera and Spodoptera litura are the most serious problems in groundnut crop. The present study was undertaken to test the effectiveness of some newer molecules against these pests in groundnut. Looking to the efficacy, yield and economics of the treatments indoxacarb 14.5% SC 0.007%, chlorantraniliprole 18.5 SC 0.006% and spinosad 45 SC 0.014% were the most effective and economic insecticides for the management of H. armigera and S. litura in groundnut.
