Effect of known antagonists on the growth of the S. oryzae in vitro a causal agent of rice grain discolouration

Abstract

Eight known antagonists were screened in vitro for their antagonism to S. oryzae by three methods viz., dual culture, pathogen at periphery and pathogen at centre. In all the three methods, Trichoderma viride, Pseudomonas fluorescens and Bacillus subtilis proved as strong and potent antagonists to S. oryzae.
