Susan,
That WAR looks bad to me; it's almost a duplicate of when my Peter Beales version of Parks Yellow Tea Scented China which got sick and then got much sicker faster than any other rose I've seen. I really hate that both sides of your stem broke; the upper side should always be the one to put out lateral growth, the undersides generally don't. Also I really don't like that the new growth is circular (as in one side is growing faster than the other.) If WAR were mine, that cane, all of that cane, would be gone tomorrow. And I'd watch where it was pruned off like a hawk.
On Cornelia, compare the time that reddish growth takes to turn green with any other new growth on that rose. The margins look a little too smooth (which is ok), and the stipules aren't exuberant. I don't like the discoloration on the leaves, but given sunlight, they should normal up.

I really never hard prune anything any more unless it's damaged and has to come out. When I dead head during the season I just snap the blooms off right below the hip. My roses get TALL by the end of the season but i like them that way. I think the roses are happier when just left to grow as they please instead of me trying to tell them how I want them to grow. And all that cane is stored energy for the plant. In bad winters I do lose it but in good ones they came back much quicker because of all that extra food stored. I tend to think we fuss and prune WAY more than we have to, lol!
I have been playing in the dirt all my life. While it has not saved me from asthma, allergies or, most recently, the tick-born red meat allergy, it has made me wildly happy, kept me grounded, brought me many friends, inspired my creative urges, and expanded my awareness and knowledge on many fronts.
I do wash my hands and face before preparing food and I keep my tetanus shots current. I also try to practice moderation in all things, common sense, and critical thinking applied to all sources of information, from sensational journalism to scientific journals.
The BBC published this article (Aug 28, 2014):
Here is a link that might be useful: link for above
I have not treated any RRV diseased roses with hydrogen peroxide nor with aspirin. This is because I have not had any confirmed cases of RRV. "From memory: early on I had a number of "RRV type" infections and I removed the whole plants. This was over several years. At some point I put the dots together. The "apparent" infections were either in the bed that was immediately downhill from the neighbor that had a lawn service or were very close to where I had used a herbicide on newly sprouted poison ivy (many places among my 1000 roses). I changed the bed next to the neighbors to a raised bed and stopped all herbicide use (except corn gluten meal). I have had zero cases since then."
The recommendations are based on results in the scientific literature for plants with other virus infections.

I don't know what they are either, but just so happens I pulled one just like your photos off the top of my rose Savannah's newest growth tonight, where the little booger had chewed off the entire tip of the new growth today. I plopped it into the bucket of sudsy water I was carrying with me (I was picking JB's at the time.) You're right, this was much larger than a rose slug.
I swear, it feels like every bug that possibly could eat roses has shown up in my garden this year....:-(
I agree that Linda from Long Ago and Burling from Burlington are great to order from and very reasonably priced, with nicely rooted plants. I find that it's most reliable for any given season to email them both to see what's current for the season, since the HMF list is only what they have potentially available in mother plants, not necessarily what's available for a given season. I have however put in "wish list" requests for next season that they both will take into account if possible in their plans.

Diane - I really appreciate this reminder you send every year and I learn to rely on it. I had about 30 roses I grow or have grown in this year's list. Not only is it great to get an automatic copy of the RIR survey results for your area each year, but there can be other perks of filling out this survey. Once years ago there were so many respondents from our region that there were random drawings of a gift certificate to people who responded from that region, which was a great unexpected perk.
Regardless, we always wish there were better information about the roses we grow or want to grow from our own region, and this is the means by which this kind of information is gathered. Even if you only grow a few roses, be sure to check it out. Most of the roses are relatively new releases but not entirely, so do check it out!

Hey Kippy. My Lady of Megginch performed the same way. Very stout basal shoots turn into arching monsters of 15 plus feet in length with one to three flowers on the end. And the thorns on these canes are outrageous. The smaller bushier part of the plant just sits there with little bloom. Makes a lopsided nightmare in the rose bed. Beyond time for shovel pruning.
Those were the types of growth Clair Martin used to "self peg" and train along stakes in the Austin bed at The Huntington. If you have the room and desire, as well as water and energy, you can frequently get flowering lateral growth from them when trained as climbers. If you don't want to or can't accommodate that style of growth, that's totally valid, but if you can and want the rose, it may be a way to keep it and make it perform for you. Kim
I have two coral drifts and 2 apricot drifts that have been in my garden for several years now. I wouldn't call them spreaders by my definition. I think of spreaders as something that roots/suckers/colonizes...my Drifts don't do that. They are wider than they are tall...if that is what is being described as spreading. They are extremely resistant to blackspot and extremely prolific bloomers. Only negatives to me are that they have no fragrance, and they aren't good about self cleaning (spent blooms hang around on the bush too long unless deadheaded).
Henry, the statement about thick red growth by the Marin Master Rosarian appears to refer to herbicides in general rather than RoundUp particularly. Overgrowth symptoms resembling RRD might be caused by 2,4D and similar chemicals.
The Oklahoma State fact sheet on RRD says,"However, excessive thorniness and unusual red pigmentation does not usually occur with glyphosate." Generally, glyphosate injury on other plants causes stunting and yellowing rather than overgrowth.
This is not the last word on the subject, but I would like to see a science-based source indicating that glyphosate causes overgrowth and redness in some roses (or any plants). I guess it's possible that a light dose causes opposite symptoms from a heavy dose.
To further complicate the situation, many men are colorblind.
That deep reddish color that some of us associate with RRD-caused growth....well, my husband is colorblind and he doesn't see that as red at all, just a slightly different green.
And, FWIW, he doesn't see it on a roses from a number of different classes; nor does he see it in photographs (when many, many in audiences do see it.)
Isn't Marin in California?
