Doug says you have powdery mildew. This is very common on garden phlox and you can see what to do about it right here. And yes, the page is about roses but the treatment is the same. :-)

My phlox have been in this garden for many years. I have not had fungal problem before - but we have had an EXTREMELY humid summer. I am confused what to do immediately spray or prune to the ground. Please help!!
