The invention relates to biotechnology and agricultural microbiology, more particularly to producing bacterial strains with fungicidal, antibacterial and growth-stimulating properties. A strain VKPM-F 1324 of Clonostachys rosea f. catenulata was produced. This strain demonstrates fungicidal properties and growth-stimulating activity and can be used as a crop protection product against various diseases caused by fungal and bacterial phytopathogens. Moreover, the strain is a producer of valuable metabolites, such as amino acids and phytohormones, which are used in agriculture. The invention, by virtue of the properties thereof, makes it possible to increase crop yield.
