2022 Cereal Rust Risk Report (June 14 to 20, 2022)

The latest Prairie PCDMN wind trajectory cereal rust risk report is available for download now at the following link: June 14 to 20, 2022 report.  

As of the week of June 14-20, 2022 the overall Prairie cereal rust risk assessments and need for in-crop scouting are as follows:

 Pacific Northwest – There was a larger number of wind trajectories that passed over the PNW region from June 14-20, 2022 and into the prairies, while key stages of crop development are occurring or starting to occur for both winter and spring wheat, respectively.  In terms of stripe rust development in the PNW there have been increasing reports of occurrence including in commercial fields.  The central to western Prairie region where most trajectories ended up did receive more moisture from June 14-20, 2022 versus the central to eastern Prairie region.  Thus, as of June 20, 2022, the risk of stripe rust appearance from the PNW is generally low to moderate, while scouting for this disease in the Prairie region should be considered for those locations that received increased trajectories and moisture.

Texas-Oklahoma corridor – Given limited leaf and stripe rust development in this corridor, a low to moderate number of recent wind trajectories from this area, and somewhat drier conditions, especially in the eastern Prairies, as of June 20, 2022, the risk of leaf and stripe rust appearance from the Texas-Oklahoma corridor is generally 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 low to moderate number of recent wind trajectories from this area, and somewhat drier conditions, especially in the eastern Prairies, as of June 20, 2022, the risk of leaf and stripe rust appearance from the Kansas-Nebraska corridor is generally limited and scouting for these diseases in the Prairies is not urgent.
