Bacterial Leaf Blight Bacterial Leaf Blight Description Bacteria are spread to African Violets by insects and improper handling. Virtually all bacteria attacking Violets are classified as bacilli.
Bacteria thrive in warm, moist conditions.
If left untreated, Bacterial Leaf Blight can be fatal to African Violets. Infected tissue at these spots may drop out of the leaves. If your African Violet exhibits this symptom, it probably has Bacterial Leaf Blight. To be sure, cut through an affected leaf with a sharp knife. If bacteria are at work, you will see gooey threads as you pull the leaf apart.
