Fusarium head blight (FHB) is present in all growing regions of small grains
and causes significant losses in yield and grain quality. In our
environmental conditions, dominant species is Fusarium graminearum Group 2.
During 2009/10 there was a significant Fusarium infestation on wheat, barley
and triticale. The aim of this study was to examine the contents of
deoxynivalenol (DON) in cereal samples taken after 2009/10 harvest season. We
analyzed 22 NS varieties of small grains from Rimski Šančevi, including 16
varieties of winter wheat, one facultative wheat variety, four varieties of
winter barley and one variety of triticale. Analytical methods based on
clean-up by solid-phase extraction (SPE) columns and detection by liquid
chromatography were used. Fifteen out the 22 analyzed samples were positive
for the presence of DON at a mean level of 0.537 mg/kg. The highest
concentration was 1.952 mg/kg. These findings were in correlation with
percentage of the Fusarium damaged kernels.
