- Аннотация: Fungi of the genus Trichoderma and preparations based on them have long been used as effective antagonists to suppress a wide spectrum of phytopathogenic microflora and to induce soil improvement. The effect of seven strains of fungus of the genus Trichoderma, isolated from the soils of different climate zones, were studied for 1) their ability to inhibit the growth and activity of pathogens, 2) their effect on the biodiversity of the soil microbiota and the increase in associative nitrogen fixation, and 3) their stimulation of growth and development of Brassica oleracea. It has been shown that Trichoderma strains isolated from the soil of agrophytocenoses, where organic fertilizers have been used for a long time, have the greatest impact in suppressing the growth and development of pathogenic microflora. These strains differ from those that are isolated from badlands due to a steady nitrogen-fixing effect and the high destruction rate of plant residues. They are characterized by a low growth rate and insignificant sporulation when compared to other strains of the same kind. However, a positive impact has been noted in the increase of the number of non-pathogenic soil microflora, and the approximation of this indicator on fertile soils. This would suggest that the search and selection of products for the development of biological preparation, potentially effective for organic farming and bio- vegetable production, should be carried out in resistant agrophytocenosis soils, as they accumulate a genetic memory for maintaining the sustainability of the soil ecosystem and for the conservation of biodiversity.
