Powdery Mildew on Palm

I am having a problem with my palm tree.  It has developed a white powdery substance on 50 percent of the leaves.

Powdery mildew often occurs on houseplants growing in low light or crowded conditions.  The shorter days and less intense sunlight of winter can increase the occurrence of this disease.  Wash off the leaves and move the plant into more light or add an artificial light if possible.  If the problem continues use a fungicide labeled for controlling powdery mildew on houseplants.   Many gardeners prefer the plant-derived fungicide formulation of Neem.  No matter what product you choose be sure to read and follow label directions carefully.
