Research on plant feedstock for farm animals and poultry is now a pressing issue. Seeding with field isolates occurs in the soil layer in the autumn period. The infestation of isolates remains in the form of spores on crop residues during the winter period. The research aimed to conduct a mycological assessment of the field isolates prevalence in soil, green mass, and agricultural products in the farms of the Agricultural Production Cooperative [APC] “Tukaya” of the Baltasinsky district, the Agricultural firm “Archa” of the Arsky district, and the APC “Kubnya” of the Kaibitsky district of the Republic of Tatarstan. The mycological screening was carried out in the specialized laboratories of the Federal Center for Toxicological, Radiation and Biological Safety. To determine the toxicity, a biotesting method based on the survival rate of ciliated cultures was used after one hour of exposure in the extract of the studied product. The climatic conditions of the spring-summer period of 2020 were characterized by increased humidity in combination with temperature changes. In the research, a spread of fungi of the genus Fusarium (F. oxysporum, F. graminearum F. sporitrichioides), Penicillium (P.notatum, P.glaucum, P.chusodepim, P. expansium) was detected in crops. And fungi of the genus Aspergillus were more often sown in grain feeds (A.fumigatus, A. flavus, A. niger). During the determination of toxicity, it was found that all the objects studied: soil, green mass, and feed are non-toxic, the survival rate of infusoria was 86%–100%. The authors recommend conducting regular feed screening and taking preventive measures that will make it possible to prevent the spread of aggressive field isolates in the agricultural complexes of the Republic of Tatarstan.
