No, I have not seen that paper and my search skills have failed me in trying to find it. A single population of virus, per genetic analysis, yes? (not too surprising, actually). It would be interesting to know about the mites, too. On the one hand there is likely to be a lot of gene flow due to their mobility, but populations at distance might still show genetic difference. The University of Arkansas team's discovery that it's a virus was a huge step forward because it clarified the battlefield, immensely. Unfortunately, the battle does not favor the rose gardener. Of the two halves of the problem, the virus itself is in some ways the lesser half. If the virus' primary or sole mode of movement were through human activities (e.g., grafting, like the mosaic viruses), the solution would be straightforward. Instead, the primary vector is an elusive, difficult-to-kill, highly mobile insect with fair likelihood of evading or resisting contact poisons/methods of any type because of its behaviors. Without a systemic miticide available, attempting to suppress or eradicate the mite population is most likely futile. Even with a systemic miticide, development of resistance is always a possibility. So, as you said, Ann, the only real strategy (other than leaving those roses where they are) is to watch closely for infection. It would be great if an accessible test for the virus in tissues were to be developed soon, rather than having to rely on morphological observations.

this spring one of my huge new dawns had rrd. i removed the plant, removed the 19 multiflora patches at the edges of my property and bought and distributed predatory mites. well another huge new dawn [i had three in all originally] has just put out fall growth full of witches brooms, so i am removing it now. it was about 30' away from the previously infected plant. there is a belinda's dream nearby with red new growth, which is small, but not really strange looking. i am keeping an eye on it, as i cant find any descriptions that mention if its new growth is supposed to be red. most of my HTs have red new foliage, and always have in the past. it is so frustrating that the biggest most vigorous established plants seem to be the hardest hit. i noticed the plants mentioned as getting RRD seemed to usually be huge climbers esp. new dawn, and shrubs, then HTs. i realized i hadnt seen minis mentioned. i searched gardenweb mini rose forum for rrd and rosette, and got zero posts about rrd. i dont know if minis are too short to get it, or mini growers are spraying miticide non-stop to kill the red spider mites, or the red spider mites are eating the eriophyid mite [which i've read can happen] ann, you posted last summer: The reasoning behind using wiltproof ties to the way that the flightless eriophyid mites get around- they are dropped by breezes when the breeze slows down. Thanks to the dissertation of Abdullah Kassar at WVU, if they land on a rose, they sense it and stay. If they land on a non-rose they try to catch the next breeze away. What we hope is happening with the wiltproof and other anti-transpirants is that they land on the wiltproof and reason "not rose" and leave. So as to how often to spray wiltproof...you'd like to keep the leaves and stems coated. Spray accordingly i bought wiltpruf to spray the new dawn i am in the process of removing, and the belindas dream i am watching. i am using it instead of hairspray. it forms a polymer coating, which i think might trap existing mites on the plants, just like the hairspray. i wouldnt give the mites that much credit in terms of intention -- it also might be that the anti-transpirants seal up the crevices they need to crawl into to not get blown about in the wind. in http://www.ars.org/pdfs/rose_rosette.pdf, it says shrub roses are most affected because their petioles provide a tight crevice, whereas HTs arent as good a host. if the mites are so prone to be blown about by the wind, maybe if the do land on a plant without good crevices,either because of the plants natural anatomy, or because wiltpruf has filled in those crevices,the mites get blown off on the next breeze before they can transmit rrd.

I'm sorry I don't have photos. On one near Knoxville, there were even denser thorns and curved stem growth and the 'rugose' leaves had spaces in between the veins that had overgrown the spaces and it almost looked as if I could pop the spaces (like an odd bubble wrap.) Up in Canada, the rugosa crosses were second or third year infections and they had canes lines with witches brooms at every leaf break/bud axils. And distorted blooms. One of the oddest things about RRD is that a certain point, the blooms stop having 'normal' sexual parts and things start to be missing. An example is the blooms on 'New Dawn' which has petals coming right out of the stems (no receptacles, no seeds, just petals.) When RRD gets into the roses gone wild in New England, I think we'll see a lot more different kinds of aberrant growth. Ann

I hope that what I consider as "shoot the messenger" type attacks have ended. https://en.wiktionary.org/wiki/shoot_the_messenger --------------------------------------------------------------------- I have learned over the years that some/many people do not look at links. I had earlier in this thread posted this link: https://sites.google.com/site/roserosettevirus/home In case you are one who did not read it, I think that it is important that you are aware of the following (from my link): "However, the following suggests (to me) that many "apparent" RRV infected roses may actually only have herbicide damage. In 2013, the Texas Plant Disease Diagnostic Lab received thirty-one symptomatic samples of different rose varieties that were tested for Rose Rosette Virus. Of those thirty-one samples, only ten returned with positives finds." The above quote is from a 2014 paper presented at a meeting. As I scientist I am trained to look for alternate possibilities. I then stated: It is also possible that there are "possible false negatives" as apparently the test used above was difficult to apply. For this reason a new test has been developed:....... ---------------------------------------------------------------- I reported the 10 out of 31 numbers in this forum: http://forums2.gardenweb.com/discussions/1701253/please-help-is-this-rose-rosette Please look at the comments after I introduced the numbers. ------------------------------------------------------------------------ Now I introduced the following: " Texas A and M is coordinating the federal funded investigation. This is what they say (as of Feb 2017): "As always, if you suspect that your rose may have rose rosette disease, please send a sample into the Texas Plant Disease Diagnostic Clinic. Many times there are other plant problems confused for RRD, and plants are taken out that may not need to be.
