ABSTRACT
The studies were taken to compare the efficacy and phytotoxicity of bioagent Verticillium lecanii 1.15% WP (1 x 108 cfu/g min.) against mealy bugs, Planococcus citri on Citrus (Acid lime) .Out of seven treatment. Quinalphos 25% EC @ 1400 ml/ha (0.07%) and Verticillium lecanii 1.15% WP (1 x108 cfu/g min.) treatments @ 3000 and 2500 g/ha were effective to control mealy bugs on citrus. All the treatments were non phytotoxic to citrus plants and non toxic to natural enemies. Verticillium lecanii 1.15% WP applied @ 2500 g/ha dose was optimum to control mealy bugs on citrus (acid lime). Based on the results the use of Verticillium lecanii 1.15% WP @ 2500 g/ha is suggested for the effective management of mealy bugs on citrus.
Key words: Verticillium lecanii , Bioefficacy, Phytotoxicity, mealy bugs( Planococcus citri) and Citrus.
