  • Rust Issues: Yellow rust and leaf rust are serious constraints to wheat production. Historically, stem rust was the major constraint.
  • Ug99 Status: No Ug99 races have been detected in the USA

Wheat rust surveillance and monitoring activities in the USA are coordinated by the USDA-ARS Cereals Disease Laboratory, St Paul, Minnesota (Stem and Leaf Rust) and the USDA-ARS at Washington State University (Yellow Rust). Full details of all rust activities in the USA can be found on the respective web sites.
