No. Dependence on that list may do harm. "Instantaneously recognizable" can't depend on those symptoms because roses react differently to RRv and symptoms change with time and exposure to (having the disesase in, and presumed titre increase) the disease. The stems and leaves are not always bright red, nor do they stay red/purple in all cultivars if they start out red. Growth may be extremely fast. Excessive thorns are not present on all infected cultivars, nor are they present on all stems. And on and on. It's a darned shame that the state extension people don't go to gardens in their own states and report what is IN their states. At one time, the extension people all reported that RRD wasn't a problem for cultivated roses. Then there was a comment unsupported by any published, juried paper, that RRD was also in the fruit trees. That, too, dropped after a year or two.

Thanks very much.

The follwing was stated by jokewing: "jJust wondering why henry kuska ONLY makes posts having to do with diseases and death? Has anyone else noticed this? Why is he even worried about roses if the thinks they are so disease ridden? " H.Kuska comment: Jockewing, perhaps your own post is a good explanation as to why I feel knowledge about what is known/unknown about rose diseases is important. "Posted by jockewing 9a (My Page) on Thu, Jul 4, 13 at 16:18 Yes Thornton, I hope you are right. With the amazing science we have today, I'm surprised more roses with such qualities have not been released. It just baffles me that the most beautiful flower we are able to grow is plagued with so many problems. Why must that be? There are so many beautiful plants that are such a breeze, but in my opinion nothing is so special as a classic hybrid tea rose. Why must they be plagued with so many diseases and pests? I admire the Knockouts, but I just don't think they are beautiful except perhaps in mass plantings from a distance, say at a commercial building or along the highway. We want giant flowered hybrid teas with the same vigor!!! It really makes me sad that virtually NO ONE I know in my area grows any classic hybrid teas at all, with may the exception of a few here or there, usually in an older neighborhood." http://forums2.gardenweb.com/forums/load/roses/msg0715030426702.html ----------------------------------------------- Additional H.Kuska comment: If you are interested in my other contributions to rose growing why not do a Google search with the search terms: "Henry Kuska" and roses or you could get a partial view at the following thread: http://forums2.gardenweb.com/forums/load/roses/msg0411322117173.html Here is a link that might be useful: link to earlier thread This post was edited by henry_kuska on Sun, Oct 20, 13 at 16:33

The virus, unless it was in the graft, comes onto the foliage through mites. It works its way down the cane to the bud union, or roots in that case. No I just got rid of the whole thing, and am still looking for the smaller roots. I really dont think the hairy roots are that much to worry about, but its hard to get all the roots. In my case it was not in the grafted canes yet. If it is an old rose, you might want to replace soil anyway. The concern about roots might be that multiflora can grow from a small root, and many grafted roses in the NE and Canada are on multiflora. Every body is trying to go own root as much as possible because of the infection in MF.
