1. To assess the prevalence and severity of barley leaf spot diseases and develop a comprehensive pathogen isolate collection.

  2. To assess the virulence and genetic variability of the spot blotch, net blotch and scald pathogens

  3. To develop a comprehensive culture collection of barley leaf spot pathogens, assess the prevalence andseverity of barley leaf spot diseases known to be important in western Canada, including net blotch, spotblotch and scald, and to maintain a coordinated surveillance network for emerging barley leaf spotpathogens, especially concerning Ramularia leaf spot.

  4. To assess the virulence of barley net blotch, spot blotch, and scald pathogens from producer’s field and studythe population genetics of barley net blotch and spot blotch pathogens in western Canada.
