M. phaseolina is an important pathogen, distributed worldwide and blackgram at all stages are susceptible to infection. The present study was undertaken to investigate the bio control potential of the native antagonists P. fluorescens, T. viride and G. mosseae for the successful biological management of M. phaseolina causing root rot of blackgram. Combined delivery system (Seed treatment + soil application) with combination of T. viride (Tv3) and P. fluorescens (Pf5) proved much superior by recording the least incidence of root rot which was on par with the fungicide treatment and also recorded the maximum growth parameters of blackgram. Among the species of AM fungi tested, the treatment with G. mosseae recorded the minimum root rot incidence, maximum per cent root infection and maximum growth parameters of blackgram in pot culture conditions.The treatment (T6) viz., Seed treatment + soil application with combination of T. viride (Tv3)and P. fluorescens (Pf5) plus soil application of G. mosseae recorded the minimum incidence of blackgram root rot and maximum biometrics of blackgram in field trial.
