The recent increase in prevalence and severity of fusarium head blight (FHB
), in cereals in Canada and elsewhere, has caused hardship and economic los
s to producers and the grain industry. This review emphasizes Canadian cont
ributions, but incorporates studies from North America to put that research
into perspective. Since the reviews of Sutton in 1982 and Miller in 1994,
significant advances in our understanding of the epidemiology of the diseas
e have occurred that are fundamental to the development of appropriate mana
gement strategies. Also, we now better understand the genetics of resistanc
e in wheat and there is a consensus that resistant cultivars will provide t
he most stable and durable solution to the problem of FHB. Our knowledge of
the genetic basis of resistance in wheat, and the development of molecular
markers to facilitate early generation selection for resistance to FHB, ar
e essential tools to this end. Resistant cultivars will ensure stable yield
s and high-quality grain free of mycotoxins.
