abstract
In order to find an alternative to organophosphates, the present study was conducted to evaluate the efficacy of some insecticides belonging to new group of insecticides and some biopesticides for the management of the pomegranate fruit borer, Deudorix epijarbas (Moore). Among the new group insecticides, rynaxypyr (0.006%), spinosad (0.002%), emamectin benzoate (0.002%) and cyazypyr (0.0075%) with 16.11, 16.67, 17.78 and17.78 per cent infestation proved effective in managing the pest. The biopesticides namely Azadirachtin, Bacillus thuringiensis and Beauveria bassiana were less efficacious where the fruit infestation recorded was 27.78, 29.44 and 30.56 per cent, respectively. The highest benefit cost ratio (BCR) was recorded in spinosad (31.39:1) followed by cyazypyr (20.00:1) treatment. Overall, earlier used cypermethrin (0.01%) was most economical (BCR 74:1) followed by deltamethrin (0.0028%) with a BCR of 46.50:1. Azadirachtin among biopesticides was economically not viable due to BCR value less than one.
