“…In addition, long distance dispersal of viable F. graminearum spores is possible (MaldonadoRamirez et al 2005;Schmale et al 2012). We speculate whether the increased prevalence of FGSC observed in several European countries (Chandelier et al 2011;Jennings et al 2004;Stępień et al 2008;Waalwijk et al 2003) including the Nordic countries (Bernhoft et al 2010;Fredlund et al 2008;Nielsen et al 2011;YliMattila 2010) may have facilitated the introduction of the 15-DON genotypes into new areas like Norway and Denmark. As such, the prevalence of 15-ADON genotypes and associated mycotoxin levels in Norwegian cereals should be monitored.…”

“…infection levels in cereal seeds, as well as the increased levels of trichothecene contamination in cereal grains, observed in Norway in recent years (Bernhoft et al 2013). During the same period, members of the Fusarium graminearum species complex (FGSC) have become more prevalent in several European countries (Chandelier et al 2011;Jennings et al 2004;Stępień et al 2008;Waalwijk et al 2003) including the Nordic countries (Bernhoft et al 2010;Fredlund et al 2008;Nielsen et al 2011;Yli-Mattila 2010), partly replacing other Fusarium species.…”

Genetic and phenotypic diversity within the Fusarium graminearum species complex in Norway

As has been observed in several European countries, the frequency of Fusarium head blight (FHB) caused by members of the Fusarium graminearum species complex (FGSC) has increased in Norwegian cereals in recent years, resulting in elevated levels of deoxynivalenol in cereal grains. The objective of this study was to determine if this increase was associated with changes in FGSC composition within Norway. FGSC isolates collected from wheat, oats and barley in Norway during two periods, mainly 1993-1998 and 2004-2007, were characterized to determine species and trichothecene genotype composition and to assess levels of genetic variation and population structure. In vitro growth rates at different temperatures and aggressiveness in spring wheat were further characterized for a sub-selection of isolates. All Norwegian isolates were identified as F. graminearum. The 3-acetyl-deoxynivalenol (3-ADON) trichothecene type was dominant. However, isolates with the 15-ADON chemotype were detected in Norway for the first time and may represent a recent introduction of this trichothecene type. Bayesian-model based clustering and analyses of genetic differentiation indicated the persistence over the last 20 years of two sympatric and partially admixed populations of F. graminearum in Norway. Significant differences in average in vitro growth rates and aggressiveness were observed between these two populations. Our results demonstrate that the recent increase in prevalence of the FGSC in Norwegian cereals do not correspond to any dramatic changes in FGSC species or trichothecene chemotype composition. However, significant changes in population frequencies were observed among Norwegian F. graminearum.

Toxigenic Fusarium species infecting wheat heads in Poland

et al. 2013

View full text Add to dashboard Cite

Toxigenic Fusarium species are common pathogens of wheat and other cereals worldwide. In total, 449 wheat heads from six localities in Poland, heavily infected with Fusarium during 2009 season, were examined for Fusarium species identification. F. culmorum was the most common species (72.1% on average) with F. graminearum and F. avenaceum the next most commonly observed, but much less frequent (13.4 and 12.5% respectively). F. cerealis was found in 1.8% of all samples, and F. tricinctum was found only in one sample (0.2%). Subsequent quantification of the three major mycotoxins (deoxynivalenol, zearalenone and moniliformin) in grain and chaff fractions with respect to associated prevailing pathogen species uncovered the following patterns. Moniliformin (MON) was found in low amounts in all samples with F. avenaceum present. In contrast, deoxynivalenol (DON) and zearalenone (ZEA) were the contaminants of F. culmorum- and F. graminearum-infected heads. The highest concentration of DON was recorded in grain sample collected in Radzików (77 µg g−1). High temperatures in Central Poland during July and August accompanied with high rainfall in July were responsible for this high DON accumulation. Trichothecene, zearalenone, enniatin and beauvericin chemotypes were identified among 21 purified isolates using gene-specific PCR markers.

“…Also, registered are products for biological protection. Plant protection against FHB, just as for other diseases, is not based solely on pesticide application but includes cultivar selection and a complex of preventive and agronomic strategies that can to a large extent prevent strong disease infection (Pereyra and Dill-Macky 2008;Chandelier et al 2011;Váňová et al 2011;Vogelgsang et al 2011;Landschoot et al 2012Landschoot et al , 2013. The purpose of comprehensive plant protection is to take into consideration all available methods that suppress the development of harmful organisms.…”

“…This group includes FHB, where some Fusarium species occur without apparent symptoms and the grain is nevertheless contaminated with mycotoxins. Although some recent papers have dealt with the effect of agronomic practices on FHB (Chandelier et al 2011;Vogelgsang et al 2011;Blandino et al 2012;Landschoot et al 2013), there remains a lack of knowledge about the effects of many factors and the interactions among them.…”

Fusarium head blight caused by a complex of Fusarium species is widespread across the world and ranks among the most serious diseases in cereals. Long-term field experiments were set up to evaluate the effects of preceding crop and soil management methods on Fusarium mycotoxin (DON, deoxynivalenol) contamination of winter wheat and spring barley grain. Winter wheat and spring barley were cultivated at two locations in the Czech Republic (A: Ivanovice na Hané during 2002-2014, and B: Žabčice during 2007-2014) with preceding crops (A) alfalfa, maize, and pea; and (B) alfalfa (only for wheat), sugar beet (only for barley), and maize. Different soil management methods also were used: (A) 22 cm tillage, 15 cm tillage, 10 cm chisel, and direct drilling; and (B) 22 cm tillage, 10 cm chisel, and direct drilling. Mycotoxin content in harvested grain was analysed using ELISA. At both locations in the experiments with both wheat and barley, year had a significant effect on mycotoxin content in grain. Preceding crop was another significant factor in wheat experiments at both locations, with DON content in grain higher with maize as the preceding crop than in the cases of other preceding crops. Soil management method had a significant effect only on mycotoxin content in wheat grain grown at Žabčice, and the highest DON content was determined in the chisel variant, in which case a large amount of harvest residue remained on the soil surface or was only partially incorporated.
