The Prairie Crop Disease Monitoring Network (PCDMN) represents the combined effort of prairie pathologists working together to support in-field disease management in field crops.
The PCDMN will release a series of weekly Cereal Rust Risk Reports throughout May and June. Read the OVERVIEW describing the collaborative nature of this effort and the methods employed. Information related to trajectory events based on forecast and diagnostic wind fields and cereal rust risk is experimental, and is offered to the public for informational purposes only.
Synopsis for May 5-11, 2020 - Wind trajectory and cereal rust risk assessment and need for in-crop scouting in the Prairie region
1. Pacific Northwest (PNW) – 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, cool Prairie weather conditions, and early stages of Prairie crop development, as of May 11, 2020, the risk of stripe rust appearance from the PNW is limited and scouting for this disease is not urgent.
2. Texas-Nebraska corridor – Given limited leaf and stripe rust development in this corridor, a relatively low number of recent wind trajectories from this area, cool Prairie weather conditions, and early stages of Prairie crop development, as of May 11, 2020 the risk of leaf and stripe rust appearance from the Texas-Nebraska corridor is limited and scouting for these diseases is not urgent.
3. Where farmers or consultants noticed stripe rust development on winter wheat in the fall of 2019, it is recommended to scout winter wheat fields that have resumed growth this spring. Scouting is especially critical where the variety being grown is susceptible to stripe rust. Currently, there are no early spring reports of stripe rust on winter wheat.
