BIOLOGICAL PRODUCT FOR STIMULATING THE GROWTH OF PLANTS AND THEIR PROTECTION AGAINST PHYTOPATHOGENS ON THE BASIS OF STRAINS OF TRICHODERMA, STRAINS OF TRICHODERMA FOR THE PRODUCTION THEREOF (VARIANTS), METHOD FOR PRODUCING A BIOLOGICAL PRODUCT ON THE BASIS OF SUCH STRAINS Russian patent published in 2017 - IPC C12N1/14 A01N63/04 C12R1/885 

FIELD: biotechnology.

SUBSTANCE: group of inventions relates to biotechnology and can be used to create bioprotection of plants against phytopathogens and to stimulate their growth. Group of inventions comprises the strains of the fungus of Trichoderma longibrachiatum species (3 options); biological product for stimulating the growth of plants and their protection against phytopathogens on the basis of these strains and the method for producing a biological product. Strains of the Trichoderma longibrachiatum fungus are deposited at the ARRIAM FSBSI under registration numbers: RCAM 03324, RCAM 03323, RCAM 03325 respectively. Biological product contains spores and fragments of mycelium of above strains from 2×10⁹ to 4×10⁹ CFU/cm³; has antagonistic activity against phytopathogenic fungi of the Fusarium and Cladosporium species. Method of producing a biological product involves a two-stage joint cultivation of strains in a quantitative ratio of 1:1:1 consistently on two nutrient media for 4–5 days. This group of inventions provides increase in seed germination on 4–15 % and the increase of linear sizes of plants on 0.5–24 %.

EFFECT: increased seed germination and the increase of linear sizes of plants.
