Management of Chilli Fruit Borer, Helicoverpa armigera (Hübner)

Experiment was carried out under field condition at Main Agricultural Research Staion, University of Agricultural Sciences, Dharwad (Karnataka, S. India) to evaluate efficacy of different biorational approaches against chilli fruit borer Helicoverpa armigera (Hübner). Among different schedules, the Nimbecidine-Nimbecidine-Spinosad-Garlic Chilli Kerosine Extract-Spinosad treatment was effective against H. armigera by recording least larval infestation and fruit damage. With respect to dry chilli yield, RPP recorded highest yield (4.44 q/ha) with maximum net return (Rs. 13767/-). While, biorational schedule involving Nimbecidine-Nimbecidine-Emamectin benzoate-Neem oil-Emamectin benzoate was the next better intervention with higher net return (Rs. 12127/-).
