Barley Fusarium Head Blight

Fusarium graminearum is a disease of great concern to wheat producers, however it can also be a problem in barley crops. The disease is carried-over on residue from previously infected crops and affects yield and quality of grain. The seed produced by the plant harbouring Fusarium graminearum contains a mycotoxin which can be highly toxic when fed to livestock. Six row barley is more susceptible than two row varieties.
