Rice seed (RD 1) were treated with two isolates of Bacillus subtilis, NSRS 89-24 and NSRS 89-26, before planting. The objective of this study was to test the antagonistic activities of the bacteria on the rice seedborne pathogens and the effect on rice seed germination and vigor. B.subtilis NSRS 89-26 resulted in the effective biological control of seed-borne pathogens of rice. The enhance growth of rice from bacteria treated seed was attributed to suppress of seed-borne pathogens and also exhibited some incident in stimulation of the growth of the plants. Bacterization with B. subtilis NSRS 89-24 had resulted a better consistent in the suppresion of rice seed-borne pathogens.
