The latest Prairie wind trajectory cereal rust risk report is available for download now at the following link: May 17-23, 2023 report.
As of the week of May 17-23, 2023 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, generally dry Prairie conditions, and relatively early stages of Prairie crop development, as of May 23, 2023 the risk of stripe rust appearance from the PNW is low and scouting for this disease in the Prairie region is generally not urgent.
Texas-Oklahoma corridor –
Given limited leaf, stem, stripe and crown rust development in this corridor, no
recent wind trajectories from this area, generally dry Prairie conditions and
early stages of Prairie crop development, as
of May 23, 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, stripe and crown 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 23, 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.
