Abstract: The research experiment was conducted in labouratory during kharif 2018 to test the efficacy of different seed treatments viz., seed dressing fungicides, bio agent i.e. Pseudomonas fluorescens and priming agents (jelly, vermiculite, coco peat and coir pith) against seed borne pathogens associated with the pod blight complex of soybean (Variety JS 335) by using rolled towel method. The results of the experiment revealed the least per cent seed infection of 7.33 per cent was noticed in seed treatment with carboxin 37.5% + thiram 37.5% @ 2 g/ kg of seed and next best treatment was seed treatment with mancozeb 50% + carbendazim 25% @ 2 g/ kg of seed with seed infection of 10 per cent. Among the bioagent and priming agents tested, T₈ (seed treatment with Pseudomonas fluorescens @ 8 g/ kg of seed + coir pith + jelly) recorded the seed infection of 15.67 with germination per cent of 95.67 and vigor index of 972.64 and this treatment was superior over chemicals with respect to per cent germination and vigor index.
