2020 Cereal Rust Risk Report (Jun 30-Jul 06)

Since 2019, the Prairie Crop Disease Monitoring Network (PCDMN) has released a series of weekly Cereal Rust Risk Reports throughout May and June.  Read the OVERVIEW describing the collaborative nature of this effort and the methods employed.  Information related to trajectory events based on forecast and diagnostic wind fields and cereal rust risk is experimental, and is offered to the public for informational purposes only.

The latest wind trajectory cereal rust risk report is available for download now at the following link: June 30-July 6, 2020 report.  


As of July 6, 2020 the risk of stripe rust appearance from the Pacific Northwest (PNW) or from regional sources is low to moderate.  However, some Prairie locations may be at an increased stripe rust risk, especially where there were 3-6 reverse wind trajectory events from the PNW.  In addition, regional development of stripe rust continues to occur, especially in southern Alberta.  See this link for the latest map of Alberta locations where stripe rust has been observed as of July 9, 2020: July 9, 2020 AB stripe rust map.   



Given the appearance of stripe rust in four counties in southern Alberta, at Beaverlodge in the Country of Grande Prairie, and the first observations in the Saskatoon area of Saskatchewan, farmers in these regions should be on the look out for stripe rust in wheat.  Special focus should be on wheat fields seeded to varieties rated as susceptible or moderately susceptible.
