Stripe rust in 2020

As of July 2, 2020, there have been five reports of the initial appearance of stripe rust on Alberta winter wheat on June 5, 16, 19, and 30, 2020 in the Counties of Lethbridge, Cardston, and Forty-Mile in southern Alberta and in the County of Grande Prairie in the Peace Region of Alberta (except of Figure 2 taken from Cereal Rust Report Week 8).  On July 2, 2020 there was also an initial report of stripe rust in the Saskatoon region (R. Kutcher, personal communication).  Given the appearance of stripe rust, 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.
