The first weekly Prairie Crop Disease Monitoring Network (PCDMN) Prairie wind trajectory cereal rust risk report for 2025 is available for download now at the following link: May 13-19, 2025 report
Pacific Northwest
- There were lower numbers of reverse wind trajectories that passed over the PNW region and into the prairies from May 13-19, 2025
- Stripe rust development continues, but is generally lower versus 2024, although further development may occur over the next several weeks
- Prairie winter wheat crops have resumed growth, while much of the spring wheat crop has just been seeded or will be seeded over the next two weeks
- Conditions in many Prairie regions have been fairly dry
- Overall, as of May 19, 2025 the risk of stripe rust appearance from the PNW is generally limited and scouting for this disease in the Prairie region is generally not urgent

Texas-Oklahoma corridor
- There were low numbers of reverse wind trajectories that passed over the TX/OK region and into the prairies
- Development of stripe and leaf rust of wheat are continuing, although levels are generally low
- Prairie winter wheat crops have resumed growth, while much of the spring wheat crop has just been seeded or will be seeded over the next two weeks
- Conditions in many Prairie regions have been fairly dry
- Overall, as of May 19, 2025 the risk of stem, leaf, stripe, and crown rust appearance from the Texas-Oklahoma corridor is limited and scouting for these diseases in the Prairie region is not urgent

Kansas-Nebraska corridor
- There were low numbers of reverse wind trajectories that passed over the KS/NE region from May 13-19, 2025 and into the prairies
- There have been limited reports of cereal rusts so far
- Prairie winter wheat crops have resumed growth, while much of the spring wheat crop has just been seeded or will be seeded over the next two weeks
- Conditions in many Prairie regions have been fairly dry
- Overall, as of May 19, 2025 the risk of stem, leaf, stripe, and crown rust appearance from the Kansas-Nebraska corridor is limited and scouting for these diseases in the Prairies is not urgent
