STRAIN OF MICROMYCETUS TRICHODERMA VIRIDAE 23 SHOWING FUNGICIDE PROPERTY FOR PREPARING COMPLEX BIOPREPARATION WITH FUNGICIDE AND BACTERIAL FERTILIZER PROPERTY, METHOD OF PREPARING COMPLEX BIOPREPARATION, COMPLEX BIOPREPARATION WITH FUNGICIDE AND BACTERIAL FERTILIZER PROPERTY Russian patent published in 2002 - IPC

FIELD: agriculture microbiology, phytopathology, farming. SUBSTANCE: invention proposes the strain of micromycetus Trichoderma viride 23 showing an antagonistic activity with respect to phytopathogenic fungi, the complex preparation with properties of fungicide and bacterial fertilizer, a method of the biopreparation preparing. Strain Trichoderma viride 23 is obtained by analytical selection of natural isolates selected after incubation of wash-off from peach surface on agarized medium. In preparing the preparation containing this strain 10 g (ml) of culture Trichoderma viride 23 grown on liquid nutrient medium Chapek-Dox are added to sterile beet pulp comprising nutrient supplements (K₂HPO₄, carbamide, chalk, sucrose) taken in total amount 2.4 g/100 of biopreparation. The obtained mixture is stirred and 10 g (ml) of culture Az. chroococcum, strain 2E-16, grown on liquid nutrient medium Fedorov with molasses and a mixture of trace elements Zn, Fe, Mo, Cu, Mg, Mn taken in the amount 0.1% (totally) are added to the mixture as an aqueous solution. The mixture is stirred thoroughly and remained for addition growing at the same temperature at periodic stirring 2-3 times per 24 h. The obtained preparation used for plant growth decreases their vulnerability with diseases and promotes to yield increase. EFFECT: strain indicated above, improved method of biopreparation preparing, valuable properties. 3 cl, 7 tbl
