    SEARCH FOR ISOLATES OF ENDOPHYTIC BACTERIAANTAGONISTS OF PHYTOPATHOGENS
    (CEP USM, 2023) Maslak, D.V.; Orunova, A.K.; Feklistova, I.N.; Grineva, I.A.; Skakun, T.L.; Lomonosova, V.A.
    Antagonistic activity of 20 isolates of non-phytopathogenic endophytic bacteria isolated from adult plants of lavender, thyme, St. John's wort and triticale against phytopathogenic microorganisms was studied in laboratory conditions. Nine isolates of endophytic bacteria antagonists of phytopathogens were selected. The ability of selected endophytic antagonist bacteria to protect spring wheat plants of the "Sudarynya" variety from diseases was evaluated in a small-plot experiment under conditions of a natural infectious background. According to the experimental results, endophytic bacteria Tr-2, D-2.1 and L-2 were proposed for research to create new phytoprotective biological preparations.

    SEARCH FOR MICROMYCETES – ANTAGONISTS OF PHYTOPATHOGENIC MICROORGANISMS
    (CEP USM, 2023) Feklistova, I.N.; Maslak, D.V.; Akiev, N.A.; Skakun, T.L.; Grineva, I.A.; Lomonosova, V.A.
    The antagonistic activity of 11 non-phytopathogenic isolates of microscopic fungi was studied. According to the results of the studies, isolates of microscopic fungi TV, T4 and 6G2, active against phytopathogenic bacteria, inhibiting the growth of mycelium of phytopathogenic fungi, were selected for further research in order to include phytoprotective action in biological preparations. Microscopic fungi TV and T4 were identified as representatives of the genus Trichoderma, micromycete 6G2 was identified as representative of the genus Penicillium, subgenus Eupenicillium.
