Stripe Rust

Also known as Yellow rust
Puccinia striiformis Westend. [teleomorph]
Uredo glumarum J.C. Schmidt [anamorph]

  1. Symptoms: The pustules of stripe rust, which contain yellow to orange-yellow urediospores, usually form narrow stripes on the leaves (picture on left). Pustules also can be found on leaf sheaths, necks, and glumes (middle picture).
  2. Development: Primary infections are caused by wind-borne urediospores that may have traveled long distances. The disease may develop rapidly when free moisture (rain or dew) occurs and temperatures range between 10-20°C. At temperatures above 25ºC, the production of urediospores is reduced or ceases and black teliospores are often produced (picture on right).
  3. Host/Distribution: Stripe rust can attack wheat, barley, triticale, and many other related grasses. The disease is found in all highland and/or temperate areas where cereals are grown. Recently the barbery was discovered to be also alternate host for stripe rust.
  4. Importance: Severe infections can cause yield losses, mainly by reducing the number of kernels per spike, test weights, and kernel quality.
