[Fusarium graminearum in silages. Zearalenone production (author's transl)].

Zearalenone natural contamination of transverse sections of recently opened silages has been observed. In our in vitro experiments, there is no zearalenone production on corn by Fusarium graminearum in anaerobic jar during 3 months. However, on confined atmosphere, zearalenone production is 1.5 to 3 ppm. Contamination of silage is not possible if there are anaerobic conditions in silages.
