FIELD: microbiology. SUBSTANCE: invention relates to a novel strain Trichoderma sp. MG-97 that can be used for protection of conifer seedlings against fusariosis. Strain Trichoderma sp. MG-97 is isolated from tree nursery soil and deposited in collection of industrial microorganisms at N F-765. Strain shows high antagonistic activity with respect to phytopathogenic microorganisms of genus Fusarium that are pathogens of conifer seedlings. Strain of fungus Trichoderma sp. MG-97 is used for protection of conifer seedlings against fusariosis. EFFECT: high competition ability of strain, rapid accumulation of biomass and active spore formation by isolate. 6 dwg, 2 ex _
