Stripe rust - an update on the Yr17 pathotype

This is to be read in conjunction with Stripe rust: Understanding the disease in wheat, NSW DPI.

Wheat stripe rust can develop on triticale, barley, barley grass, brome grass and some other grasses, but wheat is the main host. Wind spreads spores of stripe rust from pustules that develop on infected leaves. If the spores land on another living wheat leaf, they can germinate and infect the leaf. The rust grows inside the leaf and then produces pustules containing new spores.
