Has anyone had any experience with rose rosette virus?

Yes.

Immediately clear out whatever plants are affected--make sure that rose rosette is what you have and not problems due to excess rain. DO NOT compost what you clear, but burn or throw away. Rose rosette is distinct looking, with usually reddish foliage. Look online.

Thank you for the reply.

I went out and looked through the bushes real good. I don’t have any of the red canes but the buds and blooms look deformed like some of the photos.

I don’t have yellow and dropping leaves, so I had thought it wasn’t black spot. But looking closer I can see what looks like a black mildew on some of the leaves. The leaves are very dark green, so it’s hard to see.

Could that still be black spot? Is wettable sulfur the best thing for that? I really want to save the bushes because they are so carefree (usually), they require little watering and really put on a stunning show nearly year round.

Thanks for any help/suggestions that you can offer.
