Inhibition of M. oryzae vegetative growth by rice soil isolates. A) Antimicrobial assay showing the degree of inhibition of M. oryzae 70–15 by naturally isolated rice rhizobacteria as well as P. fluorescens CHAO and cyanide mutant CHA77. Error bars indicate standard error. Different letters indicate statistically significant differences between treatments (Tukey’s HSD). B) Representative images of the fungal inhibitory effect seen when 70–15 was exposed to bacterial diffusible and volatile compounds (diffusible plates), or solely through volatile compounds (volatile plates).
