The investigation, focused on exploiting the antigonistic potential of yeast Pichia spp. (strain YPS10) against fungal and bacterial pathogens, showed that Pichia spp. inhibited mycelial growth of Fusarium oxysporum f. sp. lini (57.70%) followed by Didymella naikii (50.00%). Xanthomonas campestris pv. vesicatoria, X. campestris pv. campestris and X. oryzae pv. oryzae exhibited significantly similar sensitivity to Pichia sp., with the zone of inhibition measuring from 17.60 to 19.00 mm. Formulations were developed using organic and inorganic carrier material after knowing their antagonistic nature. The results depict that the potentiality of different carriers in maintaining viability of Pichia sp., cells varied and their viability of cells lasts longer when the formulations were kept in refrigerators
