The latest Prairie wind trajectory cereal rust risk report is available for download now at the following link: May 17-23, 2022 report.
As of the week of May 17-23, 2022 the overall Prairie cereal rust risk assessment and need for in-crop scouting is as follows:
Pacific Northwest – Even though there were a number of reverse wind trajectories that passed over the PNW region and into the prairies, given limited stripe rust development in the PNW, and early stages of Prairie crop development, as of May 23, 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 May 23, 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 May 23, 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.
