In the work, based on morphological, cultural, biochemical properties and on the basis of the 16S rRNA gene, a local strain of bacteria Bacillus subtilis TM was isolated from saline soils of the Fergana region of Uzbekistan. The strain was registered with NCBI under the number: OR944512.1. It was revealed that the strain Bacillus subtilis TM exhibits high antagonistic activity against the phytopathogenic fungi Fusarium verticillioides, Fusarium solani, Aspergillus orchaceus, Alternaria alternata, Fusarium culmorium, Alternaria tenuissima with an inhibition zone of 40-60 mm. At the same time, the B. subtilis TM strain showed moderate antagonistic activity against Fusarium oxysporium, Penicillium chrysogenium (with an inhibition zone of 22-23 mm) and relatively less antagonistic activity against Cladosporium sp (with an inhibition zone of 12 mm).
