Answer by  annlees (74)

Crepe myrtles are susceptible to powdery mildew, a fungal disease that forms a white dusty coating on the foliage and limbs. Sooty mold, another fungal disease, grows on the honeydew excreted by sucking insects, such as aphids. Damp weather, poor air circulation and shady conditions are conducive to fungal diseases on crepe myrtles.

Powdery mildew is a common problem for these plants. Damp shady conditions and poor air circulation can be at fault, causing a greyish or white powdery substance to occur on leaves and flowers. Leaf spot often appears in warm weather and humid conditions. Good air circulation and no overcrowding combined with a fungicide, if needed, will help eliminate the problems.
