2022 Cereal Rust Risk Report (May 31 to June 6, 2022)

The latest Prairie wind trajectory cereal rust risk report is available for download now at the following link: May 31-June 6, 2022 report.  

As of the week of May 31-June 6, 2022 the overall Prairie cereal rust risk assessments and need for in-crop scouting are as follows:

Pacific Northwest – Given the reduced number of reverse wind trajectories that passed over the PNW region and into the prairies and generally limited stripe rust development in the PNW, early stages of Prairie crop development and drier conditions in large areas of the Prairies western regions, as of June 6, 2022 the risk of stripe rust appearance from the PNW is limited and scouting for this disease in the Prairie region is generally not urgent.




Texas-Oklahoma corridor – Given limited leaf and stripe rust development in this corridor, a limited number of recent wind trajectories from this area, and early stages of Prairie crop development, as of June 6, 2022 the risk of leaf and stripe rust appearance from the Texas-Oklahoma corridor is limited and scouting for these diseases in the Prairie region is not urgent.



Kansas-Nebraska corridor – Given limited leaf and stripe rust development in this corridor, a limited number of recent wind trajectories from this area, and early stages of Prairie crop development, as of June 6, 2022 the risk of leaf and stripe rust appearance from the Kansas-Nebraska corridor is limited and scouting for these diseases in the Prairies is not urgent.
