Since 2000, seeded barley acres in Canada have decreased by nearly half, with producers increasingly turning to other, more competitive crops such as canola.

One reason for this is the threat of diseases in barley and the increasing resistance and adaption of these diseases to fungicides.

There are several things that must be done to help combat disease problems. First, we must encourage responsible stewardship of fungicides by producers as well as the agrichemical and farm supply industries and also develop and adopt more integrated disease management strategies.

Second, we must continually monitor barley leaf disease pathogens for shifts in host virulence and fungicide sensitivity in order to gain an adequate understanding of the prevalence, severity and variability of current plant pathogens as well as new emerging disease issues. This is what this research aims to do.

The outcome of this project will be a better understanding of pathogen variation, which will help us develop resources for developing resistant varieties and integrated strategies to prolong the effectiveness of host resistance and fungicides. This knowledge and understanding will help us increase the effectiveness and durability of strategies such as host resistance and fungicide application.
