| الوصف: | Fusarium head blight (FHB) is among the major causes of reduced quality in winter wheat and its products.In addition, the causal fungi produce a variety of toxins. A relatively high FHB infection rate in winter wheat wasobserved in 2007 and 2008 in Luxembourg. A fusariotoxin survey was carried out in 17 different geographicallocations. Three groups of Fusarium mycotoxins (trichothecenes A and B and zearalenone) were analysed by amulti-detection HPLC–MS/MS method. Fusarium strains were also investigated by morphological and molecularmethods. In addition, questionnaires relating to cultural practices were sent to the farmers managing the 17 fieldsinvestigated. FHB prevalence ranged from 0.3 to 65.8% (mean: 8.5%) in 2007 and from 0 to 24.5% (mean: 8.3%)in 2008. Results of morphological and molecular identification showed that the most common species isolatedfrom diseased wheat spikes was F. graminearum (33.1%), followed by F. avenaceum (20.3%) and F. poae (17.8%).The chemical analysis revealed that 75% of the investigated fields were contaminated by deoxynivalenol (DON,range 0–8111 mg/kg). The preceding crop was highly and significantly correlated to the number of grains infectedand had a significant impact on disease prevalence ( p¼0.025 and 0.017, respectively, Fisher’s F-test). A trendwas found for maize as the preceding crop ( p¼0.084, Tukey’s test) to predict the amount of DON in the fields.This is the first report on the occurrence of DON and ZON in naturally infected wheat grains sampled fromLuxembourg. |
