The latest Prairie wind trajectory cereal rust risk report is available for download now at the following link: May 31-June 6, 2022 report.
As of the week of May 31-June 6, 2022 the overall Prairie cereal rust risk assessments and need for in-crop scouting are as follows:
Pacific
Northwest – Given the reduced number of reverse wind
trajectories that passed over the PNW region and into the prairies and
generally limited stripe rust development in the PNW, early stages of Prairie crop
development and drier conditions in large areas of the Prairies western regions,
as of June 6, 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 June 6, 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 June 6, 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.
