17-Sep-2009 (16 years 8 months 23 days ago)The Canadian Grain Commission reports a new more aggressive and toxic form of fusarium graminearum is quickly replacing the more familiar form in western Canada.
Studies conducted by the University of Manitoba are finding the 3-A DON chemotype to be much more aggressive than the previous 15-A DON chemotype.
Canadian Grain Commission mycologist Randy Clear says, since 1998 the prevalence of 3-A DON has increased from about five percent of infected wheat crops in western Canada to 40 to 50 percent.
