Influence of agro-climatic factors on the development of common soybean diseases The article presents the results of the study of the influence of agro-climatic factors on the development of major soybean diseases (varieties Anthracite, Sprytna and Perlyna) during 2016-2019 in terms of commercial crops. The dominance of the pathogens Alternaria, Fusarium, Septoria and bacterial burns among the crops was determined. The connection between the development and spread of soybean diseases and hydrothermal environmental conditions was studied. Keywords: soybean, alternariosis, septoria, fusarium wilt, bacterial burns, disease development, disease prevalence.
