ROBINIA DISEASE PROBLEMS
Several fungi cause cankers and, once the stem is girdled,
the portion beyond the infection dies. Prune off infected
branches.
Leaf spots are usually not serious enough to be controlled
chemically. Rake up and destroy infected leaves.
Powdery mildew causes a white coating on the leaves.
This problem is usually not serious.
Verticillium wilt causes branches to dieback and a severe
infection may kill the tree. Try to keep the trees healthy.
