Cyantraniliprole, A Novel Insecticide for the Management of Lepidopteran Insect Pests in Pigeonpea

The performance of cyantraniliprole 10% SE, a novel anthranilic diamide insecticide which targets the ryanodine receptors in muscle cells, is reported against the major lepidopteran insect pests of pigeonpea namely, Helicoverpa armigera, Maruca vitrata and Grapholita sp. during 2013 and 2014 under field conditions. It was tested at 40, 50, 60, 70 and 120 g a.i. ha⁻¹, in comparison with the conventional insecticides indoxacarb 15.8% EC and chlorantraniliprole 18.5% SC along with an untreated control. The application of cyantraniliprole at 60 g a.i ha¹ proved superior in reducing population of all the tested lepidopteran insect pests and pod damage, resulting in higher mean grain yield of 1306.56 kg ha⁻¹ which was superior to indoxacarb 15.8% EC (1027.03 kg ha⁻¹) and chlorantraniliprole 18.5% SC (1289.89 kg ha⁻¹).
