And this is what I found today:

Luckily a friend has some cuttings. I think this rose was snakebit. Twice it was blown off the arbor and now this. Likely because it's at the top of the hill from my backyard to the front so was more exposed to mites. I just hope it doesn't spread.....

I need to go tie by RdO up better today as she has that three year leap mode going strong. How horrible.

You can see that the healthy one is smooth, straight, the buds are not distorted, the leaves are not curled, there is a normal amount of growth. The RRD canes have too much growth, distorted buds, curled leaves and the canes were very soft and weighed down by the amount of growth. These canes were so soft, I could pull them right off the main cane. There isn't that much of a color difference, which is why I probably didn't notice it sooner.

Here is another picture:

A tell-tale sign is too many new canes or laterals coming from one cane. Here there are three coming from the same bud eye. Not normal.

That yours produced petals (maybe too many sepals on one) and was still really flexible when it bloomed.....

Early on, I would pass around gummy bear worms to mimic how flexible the sick roses canes would be when we'd expect hardened canes.

FWIW, my sick Lamarque had a very similar look several years ago and it, too, really came on fast.

However in cutting the rose down (Yes, I got rid of it, I'm not going to risk keeping this in my yard), I did see that many of the main canes had dark brown pith. And the rose hadn't looked that great lately. It had yellow leaves and was showing black spot, which it has never done before. I wonder, in addition to the RRD, it suffered more winter damage than it showed and that made the RRD worse or vice versa. Anyway, it's now chopped up in plastic bags in my trash. I still have to dig out the root ball, but not today.

I think that the Black Spot may be tied to this year's weather. Remember the horrible after Easter Freeze of several years ago. Things were growing at the wrong time of year after that and almost all of my roses had Powdery Mildew (never before then, never since). The BS might be tied to excessive pushing growth after this spring came late and the BS suppressing temperatures came later as well.

I haven't yet had RRD on my 'true' noisettes, the ones with less Tea (lovely Tea leaves) apparent in them.

One of our GW members used to spray with Wilt Pruf. She felt that the twice a month spraying would help repel the mites. I used to put Wilt Pruf in my spray, but once I stopped spraying, I also stopped using the Wilt Pruf.

For a number of years, Kaye didn't have a RRD problem. She finally did have it on one rose, but only on that one.

Jean in Nashville also tried it and had some success. Then her disease pressure went to H..... because an untended field upwind of her neighborhood was full of multiflora that got sick and the owner refused to do anything.
