Present investigation was carried out to evaluate the relative efficacy of ecofriendly formulation of Beauveriabassiana (1.3×10 6conidia/ml), Potassium silicate (50mg/lit) and Imidacloprid (75ml/acre) for sustainable management of Cnaphalocrocis medinalis. During the treatments, percent mortality, population density and infestation was observed after first and second spray application at different time intervals i.e., 2*DAT, 5*DAT, 10*DAT, 15*DAT, 20*DAT. All the treatments significantly reduced population of Cnaphalocrocismedinaliscompared to control due to their specific mode of action. Mortality was maximum (61.91%) with combined application of Potassium silicate, B. bassiana and Imidacloprid after 20th day of application. Similarly population density and infestation was lowest after application of Potassium silicate, B. bassiana and Imidacloprid after 20 days interval. The above findings showed that these combinations can be successfully integrated in future IPM programs for Cnaphalocrocismedinalis.
