Abstract
A field experiment was carried out during kharif 2021 to evaluate the efficacy of some insecticides against Spodoptera litura (F) and Helicoverpa armigera (Hubn) on groundnut. Amongst these, chlorantraniliprole 18.5SC @ 30g a.i. ha-1 proved to be the most effective with least larval counts (0.93 and 1.00 plant-1, respectively) and efficacy (63.27 and 63.70%, respectively) against S. litura and H. armigera, respectively after two sprays. This was followed by cyantraniliprole 10OD @ 90g a.i. ha-1 and novaluron 5.25+ indoxacarb 4.5SC @ 39.38+ 33.77g a.i. ha-1 giving maximum groundnut yield (22.37 q ha-1) with 52% increase over untreated control. The evaluation of economics revealed that chlorantraniliprole 18.5SC gave the highest monetary return, net income (Rs. 55765.00) and cost: benefit ratio (1:6.80).
