Help with rust

Lane County Oregon

Expert Response

Pear rust. There is no control for it once on the tree. I am enclosing the URL from Oregon State University about this disease. Often the prevention is near impossible because of many cedar trees in the vicinity. On small trees a protective cover during the infection period could help greatly.
