this infection can get quite bad - spray with an appropriate fungicide that treats for rust, and if it is bad, spray at the first sign of it next year.

Jimmyburns, it's rust and Kilmarnock willows are very susceptible to it.
I usually just let mine do its thing but believe there is a treatment for it but will leave others to recommend what to use.
