The article present the results of studies on the growth stimulating effect of the Chaetomium sp. on fungi the survival and development of grape sapling. In the study of a possible growthstimulating effect of p. Chaetomium sp is found that the survival of all grape varieties under study in the experiment exceeded the control variant. The best indicator is in the Dostoyny variety. The growth and development of saplings was better in the variant with the use of microorganisms. The average shoot length of the Kubanets grape variety in the experimental variants of 1 and 2 (100 ml/m2 and 200 ml/m2 of preparation) exceeded the control by 15.1 and 13.3 cm, respectively. In the Gordy variety, the difference between the control variant and the variants with the use of microorganisms was 12.8 and 16.5 cm. The smallest difference between these variants of experiment on the average growth length of shoots was noted in the Dostoyny variety. The study of the growth characteristics of the sapling root system in the variants with the introduction of preparation based on the fungus of the p. Chaetomium sp. showed that statistically significantly increases the total number of roots in the Dostoyny variety. In the Kubanets variety, a significant difference was noted only between option 1 and control. The Gordy variety on this index did not have a significant difference in the experimental options. The output of saplings that meet the quality standard, in variants using the preparation based on p. Chaetomium sp. microorganisms, compared with the control variant, the Dostoyny and Kubanets varieties were the largest, which in the industrial technology for the production of grafted saplings will have a significant economical effect. In terms of indicators, the most responsive to the use of the studied preparation were the varieties of Kubanets and Dostoyny.
