My Aster 'Alma P.'s.' are huge piles of mildew - what now?

My Aster 'Alma P.'s.' are huge piles of mildew - what now? I went out of town for a week and returned to giant balls of mildew. Will asters recover if I hack them to the ground? Will they come back and bloom in the fall? I really don't want to use fungicide - it scares me. I think I was crazy to think I could grow these in Missouri. They looked great until it got humid here. Thanks for any guidance you could provide.
