So sorry.

Sorry to say it but that is definitely RRD.

It is RRD.

There is a chance that if you cut that cane off as low as possible you can save the plant. Before someone comes on and poo poos that idea, you should know that I have saved roses in fall by doing that and that includes the David Austen rose 'Charles Austen' which has servived ten years of growing after the removal of the cane which had the same sort of out at the end growth as yours.

No guarantees, but it's worth a try.

I've got the same thing, msjam, this growth is showing up on a bunch of roses, and am just sick over it. Previous to this year I had one case.

Thanks, Ann, I will definitely try to cut back canes, it's sure worth a try!

I also cut off a can that was showing RRD on the end of the cane and have not seen any more RRD symptoms for 2 years.

When Maggie first showed symptoms of RRD, I did cut the infected canes off. But for some reason, 6 others got it too. It is so odd.

They may have already been infected and just not showing symptoms yet when you caught it on Maggie. I would try the cane removal and hope for the best. If symptoms return remove it immediately.

I am reasonably sure I've had the starts of RRD here. I removed my entire William Allen Richardson and cut off a couple of canes of Cornelia and Ascot. I am totally paranoid now when I see red growth in the gardenâ¦Grrrrâ¦.
Does anyone know how long the "incubation" time is from time of infestation to signs of illness?

Susan,
The one "in the field" happening that I know of was here in Knoxville.
Healthy roses moved into the front of a Lowe's 1 May for their grand opening. RRD in the field about 2/10 of a mile upwind of Lowe's.

By the end of the first week of June, there were at least twelve rose bushes with RRD there. I talked to the garden mgr and then the store mgr and got them tossed in the trash truck.

Then the state checked out the greenhouse that had grown those roses from bareroots to near bloom in pots. They found no RRD in the greenhouses, nor was there any in fields anywhere close to those greehouses.

Based on that, five weeks to really ugly growth in modern roses.

Some lab studies have taken as much as six months for the disease to show symptoms after inoculation/bud graft transmission.

But, IMO, in optimum growth conditions, that one month is pretty firm. Now if a rose is going into slowed growth in fall, often nothing will show until the following spring on HTs (what I've seen in my garden), but I think this is a function of internal physiology of the different classes of roses.

I don't think it's RRD, there are no funky thorns.....

Summerseve,
You are wrong. Not all roses have the same symptoms. On a specific rose, symptoms vary with stages of the disease.
When someone says that X is the symptom of RRD, it just means that they have no extensive experience with the disease.

When you proclaim that something isn't a contageous and lethal disease, you need to be really careful that you know your subject and that your answer does no harm.

I checked all over Evelyn tonight and she seems to be ok, all canes look normal. I will give her a chance, she's too pretty to be shovel pruned.

So sorry to hear that you have had so many infected roses. Heartbreaking! I had my first case a couple of months ago, and unfortunately, think I may have my second one now. Like Susan, even healthy growth looks suspect to me now...I'm freaked out by all new growth. This is scary stuff!
Ann, This is probably a stupid question, but from msjam's pictures, it doesn't look like Evelyn is normally a thorny rose...I'm assuming a rose that is normally thornless or nearly so would not have the ability to show "excessive thorniness" as a RRD symptom?

I grew Evelyn for three or four years (lost her to crown gall) and I remember some thorns.
I wish we knew more about thorns and why they form. There are some polys in my garden that have lots of thorns on stems, and then the stems that come from them have only a very, very few. I wonder if there is a switch of some sort in the meristem that makes a determination based on temperature, sunlight or nutrients.

I've done some searches in plant literature that have left me feeling as if I'm the only person who ever wondered about thorns. The interest is in growing roses without thorns/prickles genetically, not in the why.

Pat,, it's not a stupid question. It's just we haven't watched the disease enough to know.

Thanks for the response on thorns, Ann! I have quite a few "thornless" roses, so I have wondered what to look for on them. Abnormally red growth and excessive thorns were always what I thought of as tell tale signs. My first RRD case this summer didn't have the red coloring, but definitely had the excessive thorniness...but was a thorny rose to start with. Guess it's best to just watch for anything weird & ugly on all types of roses until more is known.

Thanks anntn6b. I'd better check on all my roses tomorrow.

Definitely appears to be RRD.
The stems are pushing growth from every bud of that leafy portion, and it shows a bit of gigantism too (look how thick it is vs. point of origin.) I lost my Cardinal de Richelieu in 2004 here from RRD.
Terrible, terrible witches broom and REDDISH, sappy, abnormal growth.

So sorry.

Steven

I finally had to shovel prune Evelyn, RRD took Julia Child as well. I am so done with this terrible disease! I've lost so many roses. :(

I'm so sorry for you guys. Ann -- thank you for your knowledge and your sharing. If RRD came to SoCal, I think I would just give up.

Sorry to hear that, I thought you saved Evelyn last year. Which state are you in? I am thinking the Merit 75 WSP should help to prevent RRD 100%, it should kill the mites which caused RRD. Am I right? I use Sevin for bugs in the Spring for years, I didn't know it gives some protection from RRD. So spray, spray and spary, to save rest of your roses. Here are some tips from this link: http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/diseases/viruses/rose-rosette.aspx

"3. Control the disease by controlling the mite. Pesticides such as carbaryl (Sevin), bifenthrin, horticultural oils and insecticidal soap may provide some protection when applied at weekly intervals during the months of June and July."

Good luck to your other roses.

I'm in Dallas area. I did a walk through in my garden yesterday, I have 6 more that I need to take out. I am soooo done with this. :(

I will not be replacing the roses.

In the Dallas area, we (Rose Societies, Master Gardeners, Extension agents and horticulturalists from all over) have launched a major campaign to educate people about Rose Rosette. Our main goal at first is to get people (including landscapers and municipalities) to remove the plants that are infecting whole neighborhoods. Scientists are working hard on it, but there is no cure at this time. Removing an infecting cane is very risky. The chances are high that it will return. The disease is caused by a virus spread by the eriophyid mite. The mite can be killed by certain miticides, but only on contact. Unfortunately, they do not stay on the surface of the rose. On a more positive note, the virus is not in the soil. If you remove the roots, you can replant - some say in a week, some say a little longer. Of course, you can re-plant with a non-rose at any time. But, if there are many infected roses in your neighborhood, there is no point in replanting until they are removed. Talk to your neighbors who have infected plants. But, we hope you will not give up. Can you imagine gardens without roses? We can't.
