I sprayed Rose Pride on my roses, as I have always done in the past, and it seems like now a lot of them have mildewed leaves, where they didn't before. Help!

Maybe you are having warmer, damper weather than you normally have? What climate or zone are you in?

Zone 9, and yes we had had more damp mornings lately, but I have not seen this much in the leaves all over the rose garden.

Some roses are more resistant to powdery mildew. And some seem to get it no matter what you do. :(
I have heard rose specialists recommend alternating two different types of fungicide, as a double whammy.
Maybe when your weather changes, the powdery mildew will go away.
