Bipolaris sorokiniana are a destructive hemibiotrophic pathogen causing root and crown rot, leaf spot and black mold of cereal crops, which significantly reduces grain yield and quality worldwide. This study investigated the antagonistic activity of  20 strains of phosphate-mobilizing wheat rhizobacteria from the genera Rahnella, Enterobacter, Bacillus, Paenibasillus and Pseudomonas against wheat diseases caused by B. sorokiniana. It was found that out of 20 strains of rhizobacteria 5 strains (Enterobacter clocae 7, Bacillus cereus 23, Pseudomonas kilonensis 24, P. kilonensis 26, P. kilonensis 30) 100% inhibited the growth of phytopathogen B. sorokiniana.
