Association among aggressiveness, fungal colonization, and mycotoxin rpduction of 26 isolates of Fusarium graminearum in winter rye head blight.

Twenty six isolates of Fusarium graminearum collected world-wide were analysed for aggressiveness for head blight of winter rye, host colonistion, ergosterol (ERG), DON and NIV production in grain samples. Twenty two isolates produced DON and four isolates produced NIV in considerable amounts. All DON producers also  produced 3-acetylDON and 18/22 produced 15-acetylDON. Mean aggressiveness was slightly higher for the DON producers. The DON/ERG ratio did not correlate with head blight rating and relative grain weight indicating that in the field DON might be not the most important factor of aggressiveness of F.graminearum.
