Stripe Rust is in Colorado!
Posted by Ned Tisserat and Scott Haley on the Cereal Rust Survey listserv: Multiple observations of stripe rust on wheat have now been made in Eastern Colorado. We just received three samples in the Diagnostic Clinic yesterday that confirms these observations. Infections thus far are most prevalent in the southeast part of the state but it appears to be moving north as would be expected. Infections at this point appear to be at low levels, but good moisture and continued moderate temperatures may promote its continued development. Wheat in SE Colorado is mostly a few days either way of the heading growth stage. If you are out scouting fields and find rust, we would like to have samples sent to the Diagnostic Clinic so we can forward them to WSU for race typing.
