Wheat Stripe Rust
Wheat Stripe Rust (WSR), Puccinia striiformis, is a fungus that causes damage to the leaf of wheat, barley, and some grasses. Rusts have been documented to have the capacity to develop into widespread epidemics. WSR can totally destroy some crop fields, and losses of 40% are common. WSR is primarily dispersed by wind. It is the most common cereal rust in the Pacific Northwest US.
Wheat Stripe Rust affects wheat, barley, barberry, and some grasses.
Wheat Stripe Rust is currently being managed by (1) using resistant varieties, (2) fungicide seed treatments and foliar fungicide treatments, and (3) removing volunteer wheat and grass weeds that could serve as a source of the fungus.
