Abstract
To ensure the sustainable development of the agricultural sector, modern research in this field must focus on creating and applying effective and environmentally safe means of protecting plants from fungal diseases. Advanced agricultural technologies enable the development of biopreparations based on microorganisms that are effective in combating phytopathogens. These biopreparations represent an innovative and promising solution for agricultural producers seeking sustainable and environmentally friendly production practices. Currently, particular attention is given to the development and use of biopreparations based on micromycetes of the Trichoderma genus, known for their broad spectrum of antagonistic activity against phytopathogens. However, the necessity of individually selecting Trichoderma strains with high antagonistic activity for the creation of biofungicides remains a pressing issue. The aim of this study is to investigate the antagonistic activity of various Trichoderma strains against phytopathogens and evaluate their potential for further use as biopreparations in agriculture. An optimal nutrient medium was selected to maximize spore production in Trichoderma. The antagonistic activity of Trichoderma strains against fungi of the genera Aspergillus, Rhizopus, Alternaria, and Mucor was assessed using the dual-culture method. Statistical analysis of the results was performed using variance analysis. Special attention was paid to studying the antagonistic activity of Trichoderma strain consortia and evaluating their potential for developing an effective biopreparation.
