Antagonism of M. testaceum B2 on M. oryzae 1637; (I) Secreted metabolite mediated antagonism; (II) Volatile Compound mediated antagonism. Percent reduction in mycelial growth of Magnaporthe oryzae was observed over control in both secreted metabolite as well as volatile mediated dual culture assays. In addition, conidial morphology deformation was observed in the secreted metabolite-mediated assay (A) Secreted metabolites mediated inhibition of M. oryzae-1637. (B) Conidial deformation due to bacterial secreted metabolites interaction with fungus (blue circle— healthy conidia; red circle—deformed conidia). (C) Volatiles of M. testaceum B2 suppressed mycelial growth. (D) Volatiles of M. testaceum B2 showed fungistasis on mycelial growth.
