“…The weather conditions were absolutely unfavorable for the spread of Fusarium infection, despite deoxynivalenol and zearalenone occurring in 90.6% and 62.5% of the samples tested respectively. In 2007, when moisture levels were high throughout the entire growing season, the contamination of wheat samples with mycotoxins was significantly higher [47]. Particularly interesting was the higher concentrations of MON in chaff fractions than in the corresponding grains infected by F. avenaceum.…”

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.

Ječmen setý je základní surovinou pro výrobu sladu v tradičních pivovarských zemích . Tato starobylá rostlina prošla při domestikaci vývo-jem od převážně potravinářského obilí po krmivo a sladovnické obilí (Basařová et al ., 2010;Hegrova et al ., 2009) . Složení mikroflóry zrna ječmene je ovlivňováno zejména geografickými a klimatickými vlivy, výživou, aplikací fungicidů, množstvím srážek od počátku metání do sklizně, odolností odrůd vůči poléhání, podmínkami během skladování ječmene a hotového sladu atd .Na ječmeni se vyskytuje široké spektrum fytopatogenních hub, které napadají rostlinu během fází růstu, zrání, sklizně (Fusarium, Alternaria, Stemphylium, Cladosporum) a skladování (Aspergillus, Penicillium, Rhizopus) (Bol et al ., 1988;Niessen et al ., 1992) . Infekce ječmene těmito patogenními vláknitými mikromycetami vede k výno-sovým ztrátám, snížení klíčivosti a sladovnické kvality zrna (Oliveira et al ., 2012) . Jako součást svého sekundárního metabolismu mohou patogenní plísně produkovat mykotoxiny . Mykotoxiny lze definovat jako přírodní produkty těchto plísní, které evokují toxickou odezvu organismu už i ve velmi malých koncentracích; z tohoto důvodu je jakákoliv kontaminace toxinogenními plísněmi potenciálně značně nebezpečná (Bennett, J . W ., 1987) .Mikroskopické vláknité houby rodu Fusarium jsou významnými patogeny obilovin . Patří mezi půdní mikroorganismy vyskytující se v oblastech Evropy, Ameriky, Asie a Austrálie s mírnými klimatickými podmínkami (Placinta, 1999;Creppy, E . E ., 2002;Malíř et al ., 2003) . Zrna ječmene jsou infikována fusariemi během kvetení i v době dozrávání . Zrna napadená v mléčné zralosti jsou silněji prorůstána myceliem, čímž se zvyšuje nebezpečí vyšší produkce mykotoxinů . Takto poškozená zrna většinou nedosahují požadova-né velikosti a zčásti bývají odstraněna již během třídění (Šafrán- Monitoring výskytu deoxynivalenolu v pivech z obchodní sítě v letech 2009-2012 Monitoring of the Occurrence of Deoxynivalenol in Beers from

BACKGROUND The aim was to determine the influence of harvesting time and meteorological conditions on the occurrence of Fusarium spp. and mycotoxins in the grain of spring cereals. A field experiment was performed in 2016–2018 with spring oat (Avena sativa L.) and spring triticale (× Triticosecale Wittm.) plots. Grain samples of oat and triticale were analysed for Fusarium infection and co‐contamination with mycotoxins deoxynivalenol (DON), zearalenone (ZEA) and T‐2 toxin (T‐2). RESULTS Results from the three‐year study showed that the occurrence of Fusarium spp. fungi and mycotoxins produced by them in spring oat and triticale grain was most influenced by the meteorological conditions at harvesting time and crop species. CONCLUSIONS It was found that in all experimental years, F. poae, F. tricinctum and F. sporotrichioides predominated in oat grains and F. graminearum, F. sporotrichioides and F. avenaceum predominated in spring triticale; as a result, oat grains were more contaminated with T‐2 and triticale grains with DON and ZEA. Due to the rainy harvesting period in 2017, the contamination level of Fusarium fungi of grain of both crop species was 100%, and the concentrations of DON and ZEA in the samples of spring triticale were several times higher than those set forth in the EU regulation. Co‐occurrence of all three mycotoxins analysed (DON, ZEA and T‐2) was identified in these samples. © 2020 Society of Chemical Industry
