Watch Out! The Green Bridge for Stripe Rust is in Place!!

Yesterday in the Swan Valley area of Idaho east of Idaho Falls, I was completing some soil sampling for research obligations and observed stripe rust on volunteer wheat that was in the boot stage. I am not sure of the variety of spring wheat. In addition, there is plenty of greenbridge material at lower elevations, and many acres of winter wheat has already been planted throughout the eastern and southern Idaho region. There was a field of winter wheat planted into emerging volunteer in the Ririe area as well. I have concerns about the setting up of a potential over-wintering of stripe rust similar to last year.
