| Summary: | The widespread production of grain crops and the rejection of the classical technology of tillage led to a noticeable increase in the prevalence and harmfulness of phytopathogens. First of all, this applies to facultative parasites with a wide specialization - Bipolaris, Fusarium, as well as secondary fungi from the genus Alternaria, Cladosporium, Penicillium, etc. At the same time, there is a change of dominance among these species. The predominant niche is occupied by fungi of the genus Fusarium, instead of species of the genus Bipolaris. The infestation of not only the seed material with this pathogen, but also the root system requires the selection of approaches to reduce this pathogen development. The use of modern fungicides with chemical or biological substances in their composition can protect plants from the pathogen and affect yield.
