Blackgram is commonly known as Urd bean (Vigna mungo (L.) Hepper). The crop is affected by number of pathogens and among them, Macrophomina phaseolina is one of the most serious seed and soil borne diseases causing significant yield losses. The present study was taen up to investigate the bio control potential of the antagonists P. fluorescens and T. virideand assess the efficient delivery systems for the successful biological management of M. phaseolina causing root rot of blackgram. The results revealed that the combination of delivery systems Seed treatment + soil application) with consortium of antagonists viz., T. viride (Tv3) and P. fluorescens (Pf5) recorded the maximum biometrics and minimum root rot incidence of blackgram.With regard to individual delivery system of the antagonist’s seed treatment with the combination of T. viride (Tv3) and P. fluorescens (Pf5) @ 10 ml kg-1 of seed and soil application, at the dosage at 4 l ha-1 recorded the minimum root rot incidence and maximum growth parameters of blackgram.
