Answer: The fungus could be powdery mildew or possibly may be the residue of an insect. To really know what to do about it you will need a positive identification. I suggest that you take a sample from the plant along with a photo of the plant in its growing location (if possible) to your County Extension Office to see if they can help diagnose the problem and recommend an appropriate course of action. Their contact information is:
