Any chance you could post pictures of the roses? It sounds like botrytis.

Thanks, I'm pretty sure you are correct. I couldn't remember the name. I know I bought fungicide from Amazon about two years ago. I searched my orders on fungicide without success and then waded through a bunch of 2016 orders and found an order for Serenade which treats botrytis. I sprayed the roses on Saturday.

Let us know how that works out! I had that earlier in the season and we'll probably get it later in the fall. Some roses seem far more susceptible such as dark desire.

It cleared up last time. I'm limited what I can do regarding rose care so I use the Bayer 3 in 1 systemic. It doesn't treat botrytis.
