Fusarium head blight (FHB), caused mainly by Fusarium graminearum, is a devastating disease of wheat and other small grain cereals. FHB lowers grain yield and quality and contaminates grain with mycotoxins, predominantly deoxynivalenol (DON) and its acetylated derivatives 3-ADON and 15-ADON. Forty one Fusarium isolates collected from grain elevators and wheat fields in Nebraska in 2009 and 2010 were sequenced for molecular identification. Forty isolates were identified as F. graminearum and one isolate was identified as F. culmorum. Seventy seven F. graminearum isolates collected from grain elevators and wheat fields in Nebraska from 2007 to 2010 were tested …
