Research and/or project statements

Our focus is the research of plant pathogens that impact cereal and oilseed production in Canada. Major plant diseases studied includes Fusarium head blight (FHB) of cereals, Sclerotinia white mold, powdery mildew and various other leaf and root diseases. Currently we are trying to develop new tools for growers to manage disease including agronomic practices disease forecast modelling and study pathogen populations and virulence. We are also studying the pathogen populations in the Maritimes and attempting to identify novel fungal virulence factors.
