Bioefficacy of Beauveria bassiana against third instar larvae of Helicoverpa armigera at different concentration


SS Shinde, NS Dale

Higher dose of B.bassiana (108 fungal spores/ml) showed higher effectiveness against third instar larvae of Helicoverpa armigera with percent mortality of larvae up to 10 DAT. The efficacy inclined gradually with advancement of time but persisted up to 10 days after treatment to induce 90 percent mortality. The B.bassiana (107 fungal spores/ml) at 10 DAT shows 76.66 percent mortality. From the result it is concluded that the mortality was time dose dependent. As the dose increased the mortality was also increase and vice-versa.
