Fir mildew, use "Immunox". Most flox in this area, other than the natives will develope mildew if they are not spayed. Spray when they first come up fir best results. Contains myclobutanil and pernethin and kills off bugs and mildew... If ya spray them early and maybe once in June, that's it. Also, a little "Liquid Fence" and not deer eating 'um either... Flox will make a grand showin'...
