The effectiveness of oil-based conidia formulations of indigenous fungal isolates Metarhizillm anisopliae M34412, Beallveria bassiana 83301 and Nomuraea rileyi N812 were evaluated against Helicoverpa armigera (Hubner) infestation on pigeon pea under field conditions. The M. allisopliae M34412 conidia in the oil formulation (7:3, diesel: Sunflower oil) were found to be most effective in controlling H. armigera. The results were compared with other control agents such as, endosulfan and HaNPV (H. armigera Nuclear Polyhedrosis Virus). The per cent efficacies were, .W. anisopliae,/i> 66.74, endosulfan 62.58, N. rileyi 60.88 and HaNPV 55.58. B. bassiana preparation was found to be relatively less effective (51.25% efficacy). The effectiveness of all the control agents based on per cent pod damage and yield has also been discussed.
