FIELD: agricultural microbiology, biotechnology.
SUBSTANCE: Penicillium vermiculatum Dang. PK-C fungus strain is prepared by selection way from Penicillium vermiculatum Dang. (VIZR-3) fungus strain and deposited in collection of pure cultures of All-Russian institute of plants protection at number VIZR-24. Proposed strain possesses high antagonistic activity against the broad spectrum of pathogens of diseases in plants. The maximal antagonistic activity of the strain is found against Sclerotinia sclerotiorum (Lib) de Bary, Phomopsis helianthi Munt.-Cvet., Michal., Petr., Botrytis cinerea Pers., and Verticillium dahliae Kleb. The strain possesses significant growth-stimulating activity increasing length and weight of seedling roots prepared from seeds treated with suspension of the proposed strain. The strain possesses resistance (compatibility) to some pesticides used for protection of sunflower, cereals, grape from complex of diseases and pests that allows using the biopreparation based on this strain in integrated system of plants protection. Invention can be used for production of biological agents used for control of phytopathogenic fungi.
EFFECT: valuable biological properties of fungus strain.
