Control of Rice Pathogens by Seed - coating with Bacillus subtilis

Abstract

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 activitives of the bacteria on the rice seed - borne pahtogens 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 th eplants. Bacterizatiion with B. subtilis NSRS 89 - 24 had resulted a better consistent in the suppresion of rice seed - borne pathogens.
