e-GRO Alert:

Report on Xanthomonas Bacterial Blight of Geranium and Look-A-Likes

Xanthomonas bacterial blight of geraniums causes small and discrete leaf spots, 1/16 to 1/8 inch diameter, that first appear water soaked, then sunken and tan or brown in color. Larger lesions and wedge-shaped yellow or necrotic lesions also develop on leaves. Under the right environmental conditions, leaf wilt and petiole cankers can occur, the growing points can die back, and plants can die. If you see these symptoms, avoid handling the plants and get a confirmation of the diagnosis by a diagnostic lab or commercial test kit.
