The latest Prairie PCDMN wind trajectory cereal rust risk report is available for download now at the following link: June 7 to 13, 2022 report.
As of the week of June 7-13, 2022 the overall Prairie cereal rust risk assessments and need for in-crop scouting are as follows:
Pacific Northwest – Although there were a larger number of wind trajectories that passed over the PNW region and into the prairies and early (spring cereals)-mid (winter cereals) stages of crop development, there is generally limited stripe rust development in the PNW, and somewhat drier conditions in large areas of the Prairies western regions. Thus, as of June 13, 2022 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 – Given limited leaf and stripe rust development in this corridor, a limited number of recent wind trajectories from this area, and somewhat drier conditions in large areas of the Prairies, as of June 13, 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.
