Prairie Crop Disease Monitoring Network - Turkington

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.  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.  Read the OVERVIEW describing the collaborative nature of this effort and the methods employed.  

Wind trajectory and cereal rust risk assessment and need for in-crop scouting in the Prairie region, May 12-18, 2020

1. Pacific Northwest (PNW) – There were a number of reverse wind trajectories that passed over the PNW region and into the prairies.  However, currently there is limited stripe rust development in the PNW, cool dry Prairie weather conditions, and early stages of Prairie crop development.  Thus, as of May 18, 2020 the risk of stripe rust appearance from the PNW is limited and scouting for this disease is not urgent.  

2. Texas-Nebraska corridor – Currently, there is limited leaf and stripe rust development in this corridor.  Moreover, there were a relatively low number of recent wind trajectories from this area, and cool Prairie weather conditions and early stages of Prairie crop development.  Thus, as of May 18, 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.
