Barley grain infection with Fusarium sp.

Fusarium head blight (FHB) is common disease of cereals all over the world and one of the most important barley diseases in Croatia. Fusarium species reduce yield quantity and quality including grain contamination with mycotoxins. The aim of our research was to determine incidence of Fusarium sp. on barley and determination of dominant species. In 2009 and 2010 barley grains grown in Croatia on four and five locations, respectively, were infected with Fusarium species. In both years all researched genotypes were infected with different Fusarium sp. Incidence of Fusarium infection varied depending on genotype susceptibility, location and year. In 2009 percentage of infected grains was between 1 (cv. Oliver, location Osijek) and 27 (cv. Sladoran, location Tovarnik). The vegetation period 2010 was favourable for FHB development. Percentage of diseased grains were higher and veried between 4 (cv. Gordon, location Osijek) and 50 (cv. Osk.6.115/1-07, location Nova Gradiška). In both years the most frequent species was Fusarium graminearum followed by F. verticillioides, F. subglutinans, F. poae etc.
