Extension Circular 1806 Revised 1955 is called Cedar Apple Rust and is about the symptoms of the Cedar Tree and Apple Tree when they rust. The symptoms of the Cedar tree are having many orange-colored, gelatinous, flower-like galls on the trees. They are first noticed in June and they grow fast over the summer months and reach adult size by fall. The spread of rust is only from the red cedar to apple trees then from the apple and related species back to the cedar.

When the leaves are infected badly they turn yellow and this weakens the tree and reduces the number and sized of the fruits. There are three ways to control the rust, 1) spraying, 2) removal of the red cedars in the vicinity of the apples, or 3) planting the more resistant varieties
