What you describe sounds like a fungal disease called powdery mildew. An application of a fungicide may be necessary to control the disease. These include: sulfur, neem oil (Rose Defense, Shield-All, Triact), triforine (Ortho Funginex), or potassium bicarbonate (Kaligreen, First Step). Be sure to apply according to label directions. Good luck with your crepe myrtle!
