Cedar apple rust disease alternates between apple and cedars.This fungal disease will also be worse in some years that have very wet weather at crucial times in spring.

See cedar apple rust on ornamentals and control. There are no chemical controls that are recommended. You would have to spray most of the summer and is not worth it.
