Popis: The study of prevalence and species composition of Fusarium fungi on sunflower and winter wheat crops was carried out in Tambov region. In 1992-2020, 15 Fusarium fungi were identified on sunflower crops. It was identified that the predominant species infecting sunflower plants and seeds are Fusarium oxysporum, F. oxysporum var. orthoceras, F. verticillioides, and F. tricinctum. The prevalence of these pathogens was 16.3-21.8%. On the grain of winter wheat, Fusarium poae, F. equiseti and F. sporotrichioides were more common (19.6-28.6%). It was found that the seeds of Lgovskaya 8, Don Awnless and Don’s Governor were less affected by fusarium infection (by 3 - 4%). It was observed that Fusarium fungi are associated with certain winter wheat varieties. Research results may be useful for specialists studying diseases of sunflower and wheat.
