R. Harichandra Naik, Shekharappa .

Abstract


A laboratory study on the bioefficacy of entomopathogenic fungal formulations against sucking pests of okra at Main Agriculture Research Station, Dharwad was conducted during 2007. The results showed that Beauveria bassiana oil and Metarhizium anisopliae oil and their WP formulations and recorded 96.67% mortality of leafhoppers at 10 DAT and Verticillum lecanii oil and B.bassiana WP formulations recorded 93.33% mortality. The efficacy against aphids revealed that V. lecanii oil based formulation showed 100% mortality followed by V. lecanii WP (96.67%)and B. bassiana oil and WP formulations (93.33%).  V. lecanii oil based formulation recorded the 97.00% mortality of thrips followed by V.lacanii WP and B. bassiana oil and WP and M. anisopliae oil (93.33%). The efficacy against mite was 96.67 and 94.67 per cent in M. anisopliae oil and WP followed by B.bassiana oil (94.00%). However, the standard check recorded cent per cent mortality of all the pests throughout the experimental period.
