1. The Role of Biofungicides in the Formation of Sustainable Agroecosystems Ovchinnikova O.P., Alyokhin V.V. Department of Genetics, Breeding, and Plant Protection Lviv National University of Veterinary Medicine and Biotechnologies named after S.Z. Gzhytskyi , Dublyany-Lviv , Ukraine

2. Background and Problem Statement Intensive use of synthetic fungicides leads to soil degradation, biodiversity loss, and resistance in pathogens. There is a global need for sustainable and ecological alternatives. Biofungicides are key tools in sustainable crop protection systems.

3. What Are Biofungicides ? Natural antagonistic microorganisms: Trichoderma spp., Bacillus subtilis, Pseudomonas fluorescens. Mechanisms of action: • Antagonism and competition • Production of antibiotics and enzymes • Induction of plant defense responses • Growth stimulation and improved nutrient uptake.

4. Benefits and Ecological Role Reduce pesticide load and chemical residues. Maintain soil fertility and microbial balance. Safe for non-target organisms (pollinators, soil fauna, beneficial insects). Prevent resistance development in phytopathogens.

5. Biofungicides and Climate Resilience Support tolerance to abiotic stresses (heat, drought, salinity). Maintain productivity under variable environmental conditions. Strengthen plant-microbe interactions ensuring long-term stability.

6. Conclusions and Perspectives Biofungicides are essential for sustainable agroecosystems. T hey combine ecological safety with crop productivity. Further research is needed on genetic and microbial aspects. Integration into breeding programs and digital agr o monitoring systems is the next step. Sustainability begins in the soil .
