SOPHORA DISEASES


Cankers caused by Fusarium lateritium will be two inches or less across, have raised reddish brown margins and light brown centers. The infected stem is killed when the fungus girdles the stem. Another fungus, Cytospora sophorae is sometimes found on dead branches on Sophora. Frost injury may give both fungi an entrance into the tree. Prune out dead, damaged, or diseased branches.

Twig blight or dieback is caused by either Nectria cinnabarina or Diplodia sophorae. Prune out infected branches and avoid unnecessary wounding. Keep trees vigorous by regular fertilization.

Powdery mildew may form a white coating on the leaves. The disease is usually not serious but can be controlled with sprays of benomyl.
