Changes in Fusarium species composition from naturally contaminated spring and winter wheat grain from the years 2005-2007 to 2011-2013 are presented. In general, Fusarium infection spring wheat grain was much more frequent than in winter wheat. In 2005-2007 F. avenaceum was dominant in both crops, with F. sporotrichioides, F. poae and F. culmorum isolated at lower levels, and F. graminearum, F. tricinctum, F. equiseti and F. oxysporum were occasionally found on both spring ant winter wheat. In 2011-2013, F. avenaceum lost its dominating status among Fusarium isolates in both crops, but the species composition of most frequently isolated fusaria in spring and winter wheat was quite different: F. graminearum, F. sporotrichioides, F. culmorum and F. avenaceum constituted the major part of fusaria isolated from spring wheat grain, while in winter wheat F. poae, F. sportotrichooides and the declining F. avenaceum were dominant.
