Abstract :
Effort were taken to compare the efficacy and phytotoxicity of bioagent B.bassiana neem formulation and insecticide. Out of six treatment Monocrotophos 36 per cent SL @ 625 ml/ha and Beauveria bassiana 1.15 per cent WP (1x108 cfu/g min.) treatments @ 3000 and 2500 g/ha were effective to reducing leaf folder larval population on paddy crop and to increase the grain yield. All the treatments were non-phytotoxic to paddy crop and non-toxic to natural enemies in both the year. Beauveria bassiana 1.15 per cent WP applied @ 2500 g/ha dose was optimum to control leaf folder and to increase the yield. Based on the results of bioefficacy and grain yield, use of Beauveria bassiana 1.15 per cent WP @ 2500 g/ha is suggested for the effective management of leaf folder larvae on paddy crop.
