A local isolate of the entomopathogenic fungus, Beauveria bassiana (ITCC-4513) was formulated as a Suspension Concentrate (SC) using mineral oil as carrier. In laboratory bioassays against 5-day-old Helicoverpa armigera larvae, the formulation had an LC50 value of 61.22 mg l-1 at 3 days after treatment. Data on shelf-life of the formulation stored in HDPE bottles at room temperature (29±1°C) was generated for 24 months. The formulation was found to be effective at 200 mg l-1 in field trials against H. armigera on sunflower crop. There was no phytotoxic effect of the formulation.
