Please tell us where you are and what roses you grow, Theresa - much
depends on that.

Spray the bushes thoroughly with a mix of one part milk, six parts water.
It works better than most commercial chemical alternatives.

I swear by it (and I usually shun organic gardening).

Interesting. Whole, reduced fat, skim milk?

Without folks like you, not all chemists will be able to make a living,

Mix it with whole milk, Radika (4% fat). Spray it liberally to run off
point, preferably undersides as well as tops.

I got rid of all spring mildew on my prone roses with 3 sprays, each 1
week apart. I never EVER got that kind of result with Triforine, Lime
Sulphur or Mancozeb. It bowled me over.

By the way, milk is equally good on black spot.

How could something so simple really work? My guess is that rose fungi
just can't deal with the proteins and fats in good old milk.
