Black Sooty Mold
Black sooty mold can appear on leaves and stems of the plumeria tree. This fungus thrives on the secretions of insects such as aphids, thrips, whiteflies, mealybugs and scale insects. Controlling insects will help deter the development of this plumeria fungus.
Rust (Coleosporium plumeria Pat.) appears as an orange powder or blistering on the underside of the plumeria leaves. This fungus appears most often after prolonged wet periods and may cause leaf drop in severe cases. Rust can be treated using a broad spectrum fungicide. The Plumeria Society of America also recommends removing all badly infected leaves.
Powdery mildew appears on plumeria leaves as a white or gray coating. It often begins in small, circular spots and then spreads to cover large areas of the leaf surface. This fungus flourishes in moist, humid conditions. Provide sufficient air circulation around plumeria trees to help reduce the risk of infection.
