Presence of deoxynivalenol in small-grain samples from 2009/10 harvest season

Abstract

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

Overview on the Mycotoxins Incidence in Serbia in the Period 2004–2016

“…An exception was the year 2014 and, to some extent, the year 2010. The results obtained by Kos et al [80] and Jajic et al [81,82] indicated that weather conditions recorded in 2014 and 2010, in terms of air temperature and the amount of precipitation, had a significant influence on DON occurrence. Samples analysed in 2014 showed a DON prevalence of 96.2% ( n = 640), with 45.6% of the samples exceeding the EU MRL (Table 3), while samples analysed in 2010 showed a DON prevalence of 73.5% ( n = 310), with 6.8% of the samples exceeding the EU MRL (Table 3).…”
