    Abstract Binnen het Uireka werkpakket Fusarium zijn in 2020 en 2021 de volgende stappen gezet: • Met een biotoets op uienbollen zijn in Uireka (1) verzamelde isolaten van Fusariumoxysporum, F. solani en F. proliferatum getest op pathogeniteit: F. oxysporum formaspeciales cepae blijkt het sterkste pathogeen, maar ook niet pathogene F. oxysporumkomen voor. • Vergelijkingen van de genomen van F. oxysporum f.sp. cepae en niet ui-pathogenen heeftlaten zien welke gen- en allelsequenties in het DNA uniek en verantwoordelijk zijn voor de pathogeniteit van een schimmel-isolaat. Op deze specifieke sequenties is een kwantitatieve op TaqMan gebaseerde diagnostische toets ontwikkeld waarmee het risico op fusarium rot gekwantificeerd kan worden. Door de test te combineren met een kweekstap op selectief medium, ontstaat een kwantitatieve Bio-TaqMan die de Fusarium dichtheid vanaf enkele sporen per gram kan vaststellen. • De Bio-TaqMan diagnostische toets is geschikt voor de detectie van F. oxysporum forma speciales cepae in plantmateriaal en in grond. In het overgrote deel van de in 2020 en 2021 verzamelde uien blijkt F. oxysporum f.sp. cepae aanwezig. In de grond bleek tijdens seizoen2021 in de uienteelt het pathogeen gemiddeld in 50-voud toe te nemen in de periode van planten tot aan de oogst. • Voor reststromen: Tijdens vergisting duurt het 3 weken om circa 99.99% van F. oxysporumf.sp. cepae te doden, maar bij continue doorstroom van materiaal in de vergister is er dus een behoorlijke kans dat levend materiaal de vergister verlaat. Bij compostering is na 1cyclus (8 a 10 dagen)meer dan 99.99% van de schimmel afgedood, na twee composteringscycli is er geen levend Fusarium materiaal meer aanwezig.

    Abstract Aspergillus section Flavi (Flavi) is a diverse group of fungal species whose common members include A. flavus and A. parasiticus. These are well-known for the production of aflatoxin (AF) B and G and other toxic metabolites, like cyclopiazonic acid (CPA). They are saprophytic soil dwellers and also become crop opportunistic epiphytes. The consequence is contamination of the crop with mycotoxins, such as carcinogenic AF. We investigated the Flavi community structure of maize and that of their surrounding soil, including their mycotoxigenicity. Furthermore, we investigated the link of the maize Flavi diversity with preharvest maize AF levels. The study was carried out in four selected districts of Zambia, in a low rainfall zone. The Flavi characterisation was triphasic, involving morphological (colony colour and sclerotia formation), metabolic (AF and CPA production) and genetic (calmodulin gene polymorphism) analyses. Flavi abundance was determined by dilution plate technique on modified rose Bengal agar. Results showed that Flavi communities on maize and in soil differed. Maize had a higher Flavi species diversity than soil. A. parasiticus dominated the soil community by frequency of field appearance (85%), while maize was dominated by A. minisclerotigenes (45%). CPA-producers with or without AF production dominated the maize (65%) while producers of only AF (B/G) dominated the soil (88%). The ratio between maize A. parasiticus and A. minisclerotigenes abundance seemed to have had a bearing on the levels of AF in maize, with a ratio close to 1:1 having higher levels than a pure community of either A. parasiticus or A. minisclerotigenes.

    Abstract Exploiting wheat cultivars with stable resistance to Fusarium Head blight (FHB) and toxin accumulation is a cost-effective and environmentally friendly strategy to reduce the risk of yield losses and contamination with mycotoxins. To facilitate the deployment of stable cultivar resistance, we evaluated FHB resistance and resistance to mycotoxin accumulation in 410 wheat lines bred by local breeders from four major wheat growing regions in China after natural infection at three distinct locations (Hefei, Yangzhou and Nanping). Significant differences in disease index were observed among the three locations. The disease indexes (DI's) in Nanping were the highest, followed by Yangzhou and Hefei. The distribution of DI's in Yangzhou showed the best discrimination of FHB resistance in cultivars. Growing region and cultivar had significant effect on DI and mycotoxins. Among the climate factors, relative humidity and rainfall were the key factors resulting in the severe disease. Even though most cultivars were still susceptible to FHB under the strongly conducive conditions applied, the ratio of resistant lines increased in the Upper region of the Yangtze River (UYR) and the Middle and Lower Region of the Yangtze River (MLYR) between 2015 and 2019. Deoxynivalenol (DON) was the dominant mycotoxin found in Hefei and Yangzhou, while NIV was predominant in Nanping. Disease indexes were significantly correlated with DON content in wheat grain.
