Abstract

Shelf life of talc based wettable powder formulation of Beauveria bassiana (Bals.) Vuill. was evaluated at room temperature (24±1°C), refrigerated condition (4°C) and in deep freeze condition (–4°C to –6°C). At room temperature, viability of conidia lasted up to 180 days with 20.22í—107 conidia/gm, having 48% pathogenicity, whereas under refrigeration the same lasted for 210 days having the same conidial density but with 69.45% pathogenicity; under deep refrigeration, though viability lasted for 300 days with same conidial load, but substantially reduced pathogenicity to 20%.
