The paper presents the studies in the field of toxin-forming phytopathogens of plant raw materials prevention. The studied isolates can be used as potential agents of biological control of fungal infections (Fusarium, Verticillum, Alternaria, Chaetomium, etc.) in agriculture. In the experiment, when silage was contaminated with the phytopathogen Chaetomium, sanitary indicators deteriorated, namely: the crude protein content when exposed to the phytopathogen Chaetomium became 26 % below control; the concentration of acid-detergent fiber when exposed to phytopathogen became lower than control by 28 %; the moisture content in the second group increased by 11 %; the concentration of dry matter when exposed to phytopathogen became lower than control by 36 %; the silage acidity index when exposed to phytopathogen became higher than control by 22 %; the concentration of lactic acid in the group with the use of the phytopathogen Chaetomium decreased by 20 %, the concentration of acetic acid decreased by 17 % compared to the control group. The use of isolates in corn silage contributed to the improvement of chemical parameters and increased nutritional value. Also, strains of Bacillus spp., Lactobacillus spp. Lactococcus spp. and 5-hydroxy-6-methyluracil can be used in the development of new effective drugs to combat various groups of pathogenic microorganisms.
