Entomopathogenic Fungi of the Genus Akanthomyces and Closely Related Species as Antagonists of Phytopathogenic Microorganisms

The antagonistic activity and its features were assessed for 20 strains and isolates of entomopathogenic fungi of the genus Akanthomyces and closely related species against eight species of phytopathogenic fungi and four variants of bacteria in vitro. Isolates of the species Akanthomyces muscarius Vl 21, Vl 29, Vl 61, Vl 72, and F 14 were selected. They showed antagonism against 5–6 species of dangerous phytopathogenic fungi (in particular, causative agents of various rots and leaf spots). Their volatile organic compounds also had a pronounced fungistatic effect, and the inhibition rate reached up to 67%. These isolates are promising for use in protecting plants from a complex of fungal diseases and pests.
