Leaf diseases such as Anthracnose, Diplodia Tip Blight, Dutch Elm disease, Crabapple Leaf disease, Oak Wilt disease and Powdery Mildew can be treated with ArborSystems Shepherd fungicide. The fungicide needs to be in the leaf before it emerges and is infected. A few more weeks remain to provide protection for leaf disease next Spring by treating trees now as the chemical can still move up into the tree. When the tree shuts down for winter and leaves drop, there is still fungicide in the buds so leaves are protected next spring. And a single application provides season-long suppression.
