title: Fusarium spp. and Fusarium mycotoxins in maize: a problem for Flanders?
abstract: Fusarium species cause not only root, stem and ear rot with severe reductions in crop yield, they produce also toxic secondary metabolites (mycotoxins) such as deoxynivalenol (DON) and zearalenone (ZEA). During several growing seasons the presence of Fusarium spp was followed up. DON and ZEA were determined and related to infection levels. The distribution of DON and ZEA in the different plant parts was studied as well as the influence of the ensiling process on the mycotoxin content. More or less important varietal differences in susceptibility for Fusarium spp. could be detected. DON and ZEA were clearly present in most of the analysed samples. No clear relationship could be detected between visual disease symptoms and mycotoxin content. The accumulation of DON and ZEA was different for the analysed aerial plant parts. The ensiling process gave no reduction of the mycotoxin content.
