ACTINOMYCES STRAIN STREPTOMYCES LYDICUS FOR PLANT PROTECTION AGAINST FUNGAL INFECTION, COMPOSITION FOR PLANT PROTECTION AGAINST FUNGAL INFECTION (VARIANTS), METHOD OF DECREASE OF SENSITIVITY OF PLANT TO FUNGAL INFECTION (VARIANTS)

摘要

FIELD: biotechnology, microbiology, agriculture. SUBSTANCE: invention relates to the strain of actinomyces that is able to inhibit growth of phytopathogens and enhance growth of plants and decrease a sensitivity of plants to fungal infection. Strain of actinomyces Streptomyces lydicus WJEC 108 is isolated from soil and deposited in American collection of type cultures (ATCC) at N 55445. Strain inhibits growth phytopathogens: Pythium ultimum, Phanerechaete chrysosporum, Coryolus versicolor, Rhizoctonia solani, Fusarium sambucinetum. On the basis of the above indicated strain a composition is prepared. This composition has strain and delivery medium including at least one of components: alginate gel, turf moss, sand, corn meal. Ammonium chloride can be added additionally as a source of nitrogen. Method of decrease of sensitivity of plant to fungal infection involves treatment of roots or seeds with the above indicated strain or strain-containing composition. Invention ensures to protect plants from phytopathogenic fungi and stimulate plant growth. EFFECT: enhanced effectiveness of the strain proposed. 11 cl, 9 tbl, 13 ex
