Abstract: The frequency of occurrence of four Fusarium spp. on wheat in the Moravia region, Czech Republic, was determined by polymerase chain reaction (PCR). Grain samples were collected during 2003-2006 at grain purchase centres. The dominant species was F. graminearum, which was recorded in all samples of the first 3 years of the study and in 88% of them in 2006. The previously more frequent F. culmorum was detected in 100 % of the samples only in 2005; in the preceding two years the frequency of its detection was lower, 84% and 60%, and in 2006 it was detected in 55% of the samples. Fusarium avenaceum had a very low occurrence in the years 2003-2004, but in 2005 it was recorded in 100% of the samples. In 2006 it was the opposite - total absence of this species. A quite different situation was found in the occurrence of the fourth species - F. poae. In the years 2005 and 2006 it was only detected in 10%, resp. 2% of the samples, compared to markedly higher occurrences in the previous years. A comparison of the current weather development with the long-term mean at the Troubsko locality suggests that years with a relatively long, wet and cold start of the growing season and warmer end of vegetation (late May-July) will favour F. graminearum.
