I would be cutting that off right now. Don't wait so that you don't loose the whole plant.

Oh and I would not wait for morning. Cut back to at least a bit further down where healthy growth. Good luck!

In agreement with Patty.

Anybody want a list of symptoms that I think I see?

Thanks Patty and Ann. I will head out as soon as it stops raiming.

I'd like the list Ann.

I had cases of RRD earlier in the year on my balcony. I have lately found 3 separate cases on my roses on the ground. This actually makes 4 cases on the ground. This location is cursed.

I'm off to bed soon. That is a lot of rrd. Do you know if there are any infected roses near you? Perhaps there are wild roses that grow in your area that you can do nothing about. Thanks goodness for your watchful eye. Got anyone that can hold an umbrella.

I just went out and cut it as close to the ground as I could see. Will check how well I did in the morning. There were 2 infected roses just a few houses down from me and I got the owner to remove them. I can't find more RRD around me besides that. I live in a a very built up area---townhouses with small yards so I am at a loss where multiflora could be. I have only lived here 2.5 years and it has been an absolute RRD Hotspot. I don't understand it. It often feels windy and is near route 1. Maybe that is enough?

Ann, yes please! I'm especially interested in the mottled color of the leaves. I see that on some of my roses occasionally.

Anne, a list of what you would see would be appreciated. I can't learn enough about this disease. I've been lucky not to experience it here so far. Lastly, wouldn't you recommend you cut that cane all the way to the ground?

I'm certainly not an expert here but here is what I thought. It was the bend followed closely by the mottled leaves and shortened space between the leaves. Plus it appears that the stem is growing thicker anything else I can't explain. There is a missing stipule on one set of leaves. That combined with the amount of rrd that Odyssey has experienced was enough.

My personal opinion is that you cut it far enough.

Sorry not Ann yet. It also appears as if that top was ready to form a bud with very short sepals. Instead of a bud it formed odd sets of leaves. I'm probably wrong but just got brave enough to throw this out there

Okay that about does it. I do pretty well at knowing rrd when I see it. However I'm a blithering idiot and well never understand this disease. I need to retire or something.

Thank you again for all the help. I knew it did not look right. To me it almost looked like a little red, deformed mini celery bunch sitting on the cane.

I did a major scout in my yard and have two more plants I am worried about. I am going to get rid of RRD early or die trying. What do you think?

Pictures of Memorial Day, fat deformed and red:

Pictures of Pretty Lady, a bloom spray is twisted and deformed:

After seeing those pictures of Memorial Day posted large, I am going back out to cut the cane off now.

Good idea on Memorial Day, It looks terrible.

I'd take that off of Pretty Lady also.

With Pretty Lady that does not look any better than MD except the red is not there. Really am sorry that you're going thru this.

It really reminds me of the first year that I had rrd. It hit and it hit hard. Many roses infected before I had any idea what I was seeing. The second year got better perhaps because there were not as many roses for the mites to land on. By the third year I started experimenting with just cutting off the damaged cane. This has worked very well for me. I only grow roses now that I can easily spot a problem on.

You are certainly doing a good job. Hopefully your cases will begin to subside a bit as well.

Thanks a lot Patty! It is really disappointing. Good thing I am stubborn. I cut off both canes. Did you take your canes off down to the ground? Some of these canes are branches off older fatter canes and I am wondering how much to leave. If I can trace the effected can straight to the ground I take it all. I am less sure when it braches multiple times and I would be taking half the plant to take the cane off to the ground.

I am including more pictures of the MD and PL canes I just cut in case it helps others make RRD identifications for themselves.

MD

PL

Two symptoms on Memorial Day : the caliper of the stems. The newer one is thicker than the one it grew from and the second and third more recent photos really show the stipules so well and they are SO DIFFERENT from the other stipules on that stem> The regular stipules....those are at the base of the compound leaf and are matched on either side of the leaf. And on the healthy leaves they are smooth with two tiny leaflets at the 'top'; on the reddish growth, the stipules look more like arugula with many leaflets and no smooth edge. Great focus on those.

On Pretty Lady, those buds are not emerging in a logical orderly way. It's as if each has a different pattern it's following.

Both of these seem to be very, very recent infections; I think you have a good chance of having good roses left after the bad canes' removal.

Thank you Ann for the continued clarification of the symptoms. I really hope I got rid of these canes quickly enough. This brings RRD cases on the ground to 6 this summer. All within the past 3 weeks! Ugh! I feel like the mites are dancing from plant to plant.

I will be watching my roses with an eagle eye every day.

Odyssey, when I notice what I believe to be a very recent infection. I have not been removing the whole cane. But if the rose has many canes then I go ahead and take out as much as I can reach. I do go at least a foot or so below the infected area. Every one needs to do what they are comfortable with thou.

Thank you Patty--you have had success saving the rose that way? I went at least a foot, more like two and took off the MD cane where it connected to the main trunk. We will see. Taking the main trunk would have meant cutting the rose in half.

I am planning now to cut first and ask RRD questions second!

Yes I have had luck with this. I don't wish to recommend it but I like you keep a close eye on my kids. I'm fairly confident that I see the infections on the same day or next morning after it starts to show. I had one last year that came up infected in spring. So I missed a fall infection. In that case it needed to be removed.

That is a good point--- I know these roses have been fine all summer until now. I will be watching, watching, watching!

Odyssey you are doing a great job and have a good eye! Keep posting so we can all learn more? But hoping you won't need to post! Thanks to Ann and Patti too. Patti don't feel too badly, like you, I know it when I see it! Thank goodness we have Ann to articulate it.

Susan

Thank you Susan, I appreciate the encouragement!

The pictures in these posts are GREAT. Is there some way that we could gather them all together in a database or flip book, or something, so that the images can be easily accessible to landscape professionals and even the general public?

Oh, and here are some pics I took in my neck of the woods, of a heavily infested planting. I am trying to get a contact for this building management to make them aware....

Felicity,

The problem with a "flip book" is that Rose Rosette doesn't have easy diagnoses.
Each cultivar has different symptoms at different stages of infection. And there are differences that are seasonal as well.

Some people still believe that hyperthorny is a good symptom and won't consider the possibility that it's a variable. Look at the pictures in the link Henry Kuska put from Ohio State of roses in Texas. Those roses are late stage RRD and IMO have probably had the disease for three or four years.

I've been collecting symptoms for over 15 years and I still see things that are new, different and bad. Three adjectives: aberrant, excessive and unexpected...are the ones I've come up with . That unfortunately requires rose growers to know what's normal and what TO expect.

For commercial plantings, do some searches on work that Dr. Mark Windham is doing with mass plantings of KnockOuts and RRD. They are showing what symptoms are and proving the symptoms are RRv with pcr tests to prove that it is the Rose Rosette virus.

Thanks!
