I don’t know what it is, but it doesn‘t look like RRD to me. Hopefully someone more experienced will chime in!

Thank you Cyndita! I didn't know if it was just a fluke or something to really be worried about. It is an own root plant. I can see what next summer brings and just prune it if it comes back. It is next to an own root Lemon Spice that has RMV, but Golden Celebration is not showing any signs of RMV. I didn't know own root roses got RMV, do you think it affects it's growth or health?

Could there have been some drift from Round-up or another insecticide? Perhaps from your neighbor's yard (if not yours)?

Might just be weather related - end of season, less sun and cooler temps.

Just to answer the RMV question. Yes, one can get RMV if the plant is grown from a cutting or bud from an RMV infected plant. For instance, if I take a cutting fomr a grafted RMV infected rose, the own root cutting will also be infected. The reason it's most closely associated with grafted roses is that much of the Dr. Huey rootstock used in the US is infected and passes that on the the grafted rose. In Europe, much of the rootstock is grown from (uninfected?) seeds so it avoids this issue.

Cyndita, thank you!

Mustbnuts, It hasn't had any pesticides near it, I don't spray, but thank you for the suggestion. :)

Dingo and Seil, thank you, I'm hoping your right!

Vaporvac, I got own root Golden Celebration from DA roses with no RMV on it, but next to it is the own root Lemon Spice I purchased from RVR that RMV showed up with in September. I talked to Janet in September and she said to email her with pictures. I emailed twice in December and haven't heard anything, so that's probably a dead horse. I wondered if RMV is catchy, or if it will affect own root Lemon Spice's health like it would in a grafted rose with RMV?

I have a couple with RMV and it only shows up at certain times of the year and hasn't seemed to affect their vigor. Of course, I'm one zone warmer than you. I have read that RMV can be transferred through pruning, but I don't know how easily that is done. Best to clean those pruner between plants.

Vaporvac , did you have your virused roses tested as to which actual virus(s) they have? Depending on the actual virus they could be spread by aphids or pollen in addition to the prunners possibility.

No, Henry. Just a visual observation and looking at the source of the rose.... not the best reputation, but they have done really well considering. They exhibited it early on, as well. I've never seen it on any of my other roses, although they may still have it. Most are own-root.

Thank you! So there's no guarantee that you won't get a rose with RMV being own root. That's unfortunate, it seems you just have to gamble when you purchase even from a reputable dealer.

Henry:

Vaporvac raises a good question. Can rose seeds "pass along" rose viruses?

Nola, that is not correct. There are vendors that guarantee their stock and it is even possible to buy clean stock from UCDavis and graft oneself. Apparently, the virus is killed at a certain temp so these plants undergo a heat treatment and are then deemed "clean". If you see a plant designated "VI" (virus-indexed), then it's undergone the treatment. I believe at least some of Burlington's, Heirloom's and RVR's plants have this designation. I do feel most OR places have good stock. Thus far it hasn't affected my 2 grafted plants too badly, but then I don't have a clean plant to compare. : ((

Thank you, I think I'll have to ask before I buy. :)

I suggest taking care not to have Golden come in contact with other roses. I had a large healthy Heritage than exhibited strange leaves in Feb March of last year. I was certain it was not RRD but as time when on they continued to be semi strange looking on several arms, although nothing like any examples of RRD. I sprayed for the mite and sent a sample off to be tested just to be on the safe side. Unfortunately, it was RRD. I was told they also did not think it was infected by just a visual. My Heritage never developed any other tell tale signs but I of course removed it immediately when I got the results. I ended up contaminating 2 other bushes when clipping flowers for the house. Cinco began to show typical signs but Mun Woods did not, the only symptom was thorns and not that different from MWood's usually thorny self. My point is the RRD can fool you and I have become alert to anything unusual on my roses. Better safe than sorry. Hope I am totally wrong and that this was a waste of effort to share and read.

Never a waste of effort to either share or read. Thank you and I'm sorry about your losses. Did you post them here as I'd be interested to see that foliage?

Thank you Austinkisses, I'm on a first name basis with the plant pathology dept. at UW Madison since having crown gall a few years back. I'll send in a sample as soon as it gets warm enough.

Thank you and I agree with you Vaporvac, it's great to be informed about what to watch out for, especially for the more inexperienced like myself. :)

Crown Gall

It's hard to like that picture!

She's a beauty isn't she Vaporvac? We should have a main thread of rose diseases and issues that one can post to at any time and others can explore! I think they do that on Gardenweb.

That is one very ugly gall; Scary actually. Hope u solved the problem -what caused it? I am unfamiliar with gall have never had that problem.

The only solution is to dig it up to get rid of it and as much soil around it, then wait 3 years before planting there again. I first sent off a picture and sample to the UW Madison plant pathology lab for diagnosis.

" Crown gall is a disease caused by the bacterium Agrobacterium tumefaciens (synonym Rhizobium radiobacter), which enters the plant through wounds in roots or stems and stimulates the plant tissues to grow in a disorganised way, producing swollen galls. "

" Symptoms include roundish rough-surfaced galls (woody tumourlike growths), several centimetres or more in diameter, usually at or near the soil line, on a graft site or bud union, or on roots and lower stems. The galls are at first cream-coloured or greenish and later turn brown or black. "
