The latest Prairie wind trajectory cereal rust risk report is available for download now at the following link: May 10-16, 2023 report.
As of the week of May 10-16, 2023 the overall Prairie cereal rust risk assessment and need for in-crop scouting is as follows:
Pacific Northwest – Even though there were several reverse wind trajectories that passed over the PNW region and into the prairies, given limited stripe rust development in the PNW, generally dry Prairie conditions, and early stages of Prairie crop development, as of May 16, 2023 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, stem, and stripe rust development in this corridor, a limited number of recent wind trajectories from this area, generally dry Prairie conditions and early stages of Prairie crop development, as of May 16, 2023 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 – Given limited leaf, stem and stripe rust development in this corridor, a limited number of recent wind trajectories from this area, generally dry Prairie conditions, and early stages of Prairie crop development, as of May 16, 2023 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.
