The disease is spread throughout the tree, or from tree to tree, by splashing rain and winds that move the fungus from diseased areas to healthy parts of the tree.Prune and remove all dead wood. The pruning should be a few inches below the diseased area, so as to remove as much of the fungal concentrations as possible. When pruning do not remove branches that have recently wilted as they may reflush again in a few weeks or the following spring.
