If so, you have a fungus called powdery mildew. Your local garden center will have a general purpose fungicide that will work for well on powdery mildew. If the white on the leaves is more of a lacy pattern on the leaf that can not be wiped away, your azalea has been attacked by an insect called lace bug.
