To overcome the high costs associated with mycotoxin analysis, assessments of FDK, in addition to being a more affordable method, usually correlate more strongly with mycotoxin levels than visual assessment of the wheat spikes, and could be used as a surrogate variable to select for resistance to mycotoxin (Mesterházy et al, 2005;Sneller et al, 2012).…”

Mycotoxin levels in Fusarium head blight (FHB) infections can be difficult to quantify.The relationship between mycotoxin and disease is not consistent and it is not clear if wheatpathogen interaction is of significance in regions where more than one Fusarium species with distinct trichothecene production ability co-exists. This study aimed to investigate whether a set of eight Brazilian wheat genotypes, varying in resistance according to classification by the breeder, exhibit a common or differential resistance to Fusarium graminearum (Fgra) (deoxynivalenolproducing) and Fusarium meridionale (nivalenol-producing) (Fmer) using full-spike and central spikelet inoculation (type II resistance). Fgra was generally more aggressive than Fmer based on the percentage of diseased spikes (99 and 84 %, respectively) and number of diseased spikelets (mean 2.8 and 2.0, respectively) below the central spikelet. The genotype-pathogen species interaction was not significant, but there were differences between the genotypes, with BRS 194 and BRS 327 being the least and most resistant, respectively, based on severity ratings. The incidence of Fusarium-damaged kernel (FDK, %) was not affected by species, but two genotypes , respectively, suggesting that Fgra is a more potent producer of trichothecene. Our data confirm prior resistance classifications by the breeders and suggest that the use of a single highly aggressive Fgra isolate may be sufficient for effective screening for FHB resistance. However, further studies are needed to elucidate the accumulation of resistance to trichothecene.

“…In the case of the latter two mycotoxins, the correlation coefficient was close to unity (0.931-0.932). According to Waśkiewicz et al (9), Zhang et al (56), and Ji et al (57), mycotoxin content in grain positively correlates with the severity of FHB. By contrast, Lacey et al (58) reported the presence of DON in grain with no macroscopic symptoms of FHB or grain colonisation by Fusarium spp.…”

The fungi of the genus Fusarium cause Fusarium head blight (FHB), a devastating disease that reduces grain yield and quality. They also produce mycotoxins which may pose a serious threat to human and animal health. This study investigated the effects of NPK fertilisation, foliar application of Cu, Zn, and Mn, applied separately and in combination, and of the Nano-Gro ® organic growth stimulator on the occurrence of FHB in cultivar Dańkowskie Diament rye based on the mycological analysis of kernels and on the concentrations of Fusarium mycotoxins in grain. The severity of FHB caused by seven species of the genus Fusarium was influenced by weather conditions in the analysed growing seasons. The applied fertilisation and the Nano-Gro ® organic growth stimulator exerted varied effects on FHB development and the biosynthesis of Fusarium mycotoxins (deoxynivalenol, nivalenol, zearalenone and fumonisins) in grain. The greatest reduction in deoxynivalenol and nivalenol concentrations was noted in 2013, and the levels of moniliformin were lower in treated samples than in absolute control (untreated) samples in both years of the study. The severity of FHB positively correlated with the concentrations of zearalenone, deoxynivalenol, nivalenol, and moniliformin in the grain samples. Greater accumulation of ergosterol was noted in the rye grain harvested in 2013 than in 2012, and fertiliser treatment led to higher ergosterol concentrations than did control treatment. KEY WORDS: deoxynivalenol; ergosterol; fertilisation with microelements; FHB; fumonisins; fungi; moniliformin; nivalenol; zearalenone Fusarium spp., common in all climate zones, can cause many diseases in cereal crops (1-4). These fungi are transmitted through soil and crop residues, compromising plant health as the infection spreads (5). Their pathogens attack plants from the early stages of development (BBCH 30) to maturity (BBCH 77 (3,(7)(8)(9)(10). Fusarium culmorum and F. avenaceum are the most common in Europe, including Poland (2-3, 11). According to Rintelen (12), F. poae and F. tricinctum are more common than F. culmorum and F. graminearum when dry and cool conditions that prevail during flowering are followed by a wet period at a later stage of development. Champeil et al. (13) found that the severity of FHB in wheat is largely determined by high relative humidity, wind, and rainfall during flowering and harvest.According to the literature (14-15), these pathogens differ in their responses to fertilisation with nitrate (N), phosphate (P), potassium (K), and microelements. High N fertilisation levels seem to increase the severity of infections with obligate pathogens but decrease the severity of infections with facultative parasites, including Fusarium spp. (16). Potassium reduces the host plant's susceptibility to infections, but only when applied at optimal rates. Unlike potassium's, phosphate's role in plant resistance to pathogens varies considerably. Microelements such as Cu, Zn, Mn, and B, in turn, seem to be involved in a plant's physiological...

“…Indeed, in addition to the resistance mechanisms that determine the severity of FHB attack on the wheat plant, other mechanisms may influence DON content in kernels, e.g., DON degradation or conjugation and tolerance (Ji et al, 2015). In particular, DON binds covalently to hydrophilic molecules, such as glucose and glutathione (Audenaert et al, 2013;Cirlini et al, 2014).…”

The deoxynivalenol (DON) occurrence in durum wheat (Triticum durum Desf.) kernels is a key food safety issue, hence more and more attempts have been made to increase the availability of resistant cultivars. Within this framework, this work focused on the analysis of the behaviour of several durum wheat cultivars widely grown in Italy in relation to the level of deoxynivalenol contamination in whole milled kernels. A total of 2844 samples were submitted for deoxynivalenol analysis by enzyme-linked immuno-sorbent assay. The statistical analysis by generalised linear models provided a trend ranking of durum wheat cultivars on the basis of the deoxynivalenol contamination level, depending on each cultivation area assayed. This study provided a better understanding of cultivar susceptibility to mycotoxin accumulation in grains. The role of the factor cultivar has clearly emerged. However, other environmental factors, such as growing area, have a great influence on the DON concentration levels in the cultivars tested.
