Many microbial antagonists have been reported to possess antagonistic activities against fungal pathogens, such as Pseudomonas fluorescens, Agrobacterium radiobacter, Bacillus subtilis, B.cereus, B.amyloliquefaciens, Trichoderma viride, T.harzianum, Burkholderia cepacia, Saccharomyces sp. and Gliocadium virens. In present investigation antagonistic potential of native bacterial strains i.e. Providensia vermicola AAU PR1 (KJ161325), P.putida AAU PR2 (KJ161326) and P.fluorescens AAU PR3 (KJ161327) against various phyto-pathogenic fungi viz., Alternaria alternata (ITCC-5503) from chilli, A.alternata (ITCC-6134) from tomato, A.alternata (ITCC-7067) from potato, Aspergillus niger (ITCC-6202) from Citrus reticulate, A.niger (ITCC-6738) from sorghum seeds, M.phaseolina (ITCC- 6734) from tomato seeds, M.phaseolina (ITCC-6749) from soybean seeds, Pythium aphanidermatum (ITCC-5488) from ginger rhizome, Fusarium solani (ITCC-6846) from chilli roots. All the native strains were found to restrict mycelial growth of fungal pathogens. To the best of our knowledge and literature surveyed this is the first time report showing antagonistic activity of Pr. vermicola against phyto-pathogenic fungi causing severe loses in variety of crops.
