An experiment was conducted in Department of Plant Pathology, N. M. College of Agriculture, N.A.U., Navsari to isolate, characterize and evaluate antagonistic efficacy of Pseudomonas spp. The six Pseudomonas spp. were isolate from different locations of south Gujarat and evaluated antagonistic efficacy in vitro against Pyricularia oryzae Cavara (Finger millet blast), Colletotrichum falcatum Went (Sugarcane red rot), Fusarium moniliformae Sheldon (Sugarcane wilt), Macrophomina phaseolina (Tassi) Goud (Chickpea root rot), Sclerotium rolfsii Sacc. (Groundnut stem rot), Pythium aphanidermatum (Eds.) Fitz. (Tobacco damping off), Pestalotiopsis anacardii (Pestolatia blight of mango), Lasiodiplodia theobromae Pat. (Stem end rot of mango), Xanthomonas axonopodis pv. oryzae (Bacterial leaf blight of rice), Xanthomonas axonopodis pv. malvacearum (Bacterial leaf blight of cotton) and Xanthomonas axonopodis pv. citri (Citrus canker) pathogens. Among the six isolates, PaRS (Pseudomonas aeruginosa Rambhas soil) showed maximum growth inhibition and minimum growth of pathogens. PaRS has dirty green colour and colonies were round and non-spreading with rod shaped cells.
