The present investigation was carried out on a compatibility between different microbial pesticides through Dual culture technique and Pot culture assays. In dual culture, per cent inhibition of radial growth of T. viride in treatments T. viride + P. fluorescens and T. viride + M. anisopliae, revealed that T. viride covered the full plate and it showed an antagonistic effect on P. fluorescens and M. anisopliae. Thus, it was found that they were not compatible with each other. While, P. fluorescens inhibited M. anisopliae upto 19.01 per cent. In pot culture assay at 45 days after soil treatment with different combinations of microbial pesticides viz., T. viride, M. anisopliae, P. fluorescens, T. viride + M. anisopliae, T. viride + P. fluorescens M. anisopliae + P fluorescens, T. viride + M. anisopliae+P. fluorescens and control, at 10^-2, 10^-3, 10^-4 concentrations revealed that T. viride was found to be most dominant and M. anisopliae growth was nil. While, P. fluorescens was observed at higher concentrations of 10^-5, 10^-6, 10^-7.
