A laboratory trial was conducted to know the bio-efficacy of Verticillium lecanii and Beauveria bassiana alone and in combination with reduced dose of two insecticides against third nymphal stage of Lipaphis erysimi (Kalt.) at Junagadh Agricultural University, Junagadh during 2005-06. The results showed that the insecticides, imidacloprid 0.005 per cent and acephate 0.05 per cent alone were found most effective, while, application of V. lecanii at half concentration with either imidacloprid or acephate at half dose, i.e. 0.0025 or 0.025 per cent, respectively, was found as effective as synthetic insecticides alone against L. erysimi.Keywords
