Temporal Variation of Mycotoxin Producing Fungi in Norwegian Cereals.
Spring barley is grown on about half of the Norwegian cereal area. The rest of the area is equally divided between wheat and oats. Most years the domestic production provides 70%-80% of the domestic market for bread wheat. Barley and oats are mainly grown for animal feed. During the years 2008-2012, severe epidemics ofFusariumhead blight have led to increased mycotoxin contamination of cereals. During that period, precipitation was above normal during anthesis and grain maturation. The most important mycotoxin producers have beenF. avenaceum,F. culmorum,F. graminearumandF. langsethiae. Increased deoxynivalenol contamination of Norwegian cereals during recent years is due to severeF. graminearumepidemics.
