Impact of growth conditions on the occurrence ofFusarium spp. and the mycotoxin content of wheat.

In 1997-99 the occurrence ofFusarium spp. on winter wheat and the contamination with mycotoxins was investigated at three locations in the Rhineland, Germany. All cultivation methods investigated had an effect on the level ofFusarium infection, however, rainfall during flowering was the most important factor. The choice of cultivar and soil cultivation proved to be the most promising tools to reduce head scab severity and mycotoxin contamination.
