Effect of Microbial Antagonists on in vitro Growth of Pythium aphanidermatum

Imran Ali Siddiqui    

Abstract: Forty-one isolates of 38 species of fungi and 24 isolates of 8 species of bacteria were tested in dual culture plates. Penicillium sp., 2 unidentified bacteria and a sterile fungus were found to inhibit the growth of Pythium aphanidermatum producing zones of inhibitions of 7, 11,4 and 6 mm respectively, around the colony of the pathogen. One strain each of Rhizobium meliloti, Bradyrhizobium sp., and Pseudomonas aeruginosa initially producing zones of inhibition of 15, 20 and 2 mm respectively, but later the pathogen grew and colonies met each other. Similarly, G. , virens initially produced a zone of inhibition of 20 mm but later on the pathogen over grew the zone of inhibition and colonies intermingled. A strain of P. aeruginosa also inhibited the growth of P. aphanidermatum without producing zone of inhibition.
