WISTERIA DISEASES
Crown gall causes formation of galls on the main roots or stems. There is no chemical control. Remove and destroy infected plants.
Leaf spots may be seen, but infected leaves can be picked off. Basic copper sulfate should control leaf spots.
Powdery mildew coats the leaves with a white, powdery growth. Use sprays of benomyl or sulfur.
