A representative set of barley samples collected in the Czech Republic in 2005-2010 was used to evaluate the occurrence of Fusarium mycotoxins deoxynivalenol (DON) and zearalenone (ZEA), the effect of agronomic factors on the level of mycotoxin contamination and the presence of four Fusarium species (F. avenaceum, F. culmorum, F. graminearum and F. poae). A significant correlation between the year and DON as well as ZEA content in barley, and significant effects of the preceding crop and variety on DON content were confirmed. The highest level of DON content was found in grain harvested in 2009, which was in correspondence with extremely frequent detection of the producer of this mycotoxin, F. graminearum, in this year. In the other years, F. poae predominated on barley.A representative set of barley samples collected in the Czech Republic in 2005-2010 was used to evaluate the occurrence of Fusarium mycotoxins deoxynivalenol (DON) and zearalenone (ZEA), the effect of agronomic factors on the level of mycotoxin contamination and the presence of four Fusarium species (F. avenaceum, F. culmorum, F. graminearum and F. poae).
