Abstract

The article analyzes the negative environmental impact of chemical pesticides in the fight against plant diseases and highlights the advantages of biological control methods. In particular, the antagonistic properties of fungi belonging to the Trichoderma genus against phytopathogens, their action through the production of antifungal metabolites, competition for nutrients and territory, and mycoparasitism mechanisms are scientifically described. The evolutionary development and ecological adaptability of Trichoderma species are also considered. Studies show that the effectiveness of these fungi is largely related to climatic factors and soil microbiota, and strains adapted to local environmental conditions give especially high results. The insufficient development of the biofungicide market in Uzbekistan, the high cost of imported products, and the decrease in their effectiveness in a sharply continental climate increase the need to isolate and study local Trichoderma strains. Therefore, in-depth research and implementation of the antagonistic properties of local strains is considered a promising direction.
