Efficacy of cyantraniliprole 10 SE in insect pests management on Pigeon pea

Abstract

New Suspo Emulsion (SE) formulation of anthranilic diamide insecticide, cyantraniliprole 10 SE was evaluated during rabi season of 2013–14. Four doses of cyantraniliprole 10 SE along with thiamethoxam 25 WG and chlorantraniliprole 18.5 SC as standard checks against insect pests of pigeon pea were evaluated for bioefficacy as well as its influence on natural enemies and crop health. Nymphal and adult population of aphids, Aphis craccivora; thrips, Megalothrips usitatus; larval population of pod borer, Helicoverpa armigera; Legume pod borer, Maruca testulalis; pod fly, Melanogromyza obtusa was effectively controlled at 60 and 70 g a.i/ha doses of cyantraniliprole 10 SE. Whereas, thiamethoxam 25 WG @ 25 g a.i/ha found effective for the control of nymphal and adult population of thrips. Chlorantraniliprole 18.5 SC @ 30 g a.i/ha significantly controlled the larval population of pod borer; legume pod borer; pod fly. Cyantraniliprole 10 SE @ 40–70 g a.i/ha found safe to natural enemies as these treatment doses did not reduce the natural enemies population in the field during the course of investigation.
