No it was not a quote. I would call it an attention getter. Michaelg, isn't the English language your specialty (after trout fishing, of course)? If so please help me out here. What is it called formally?

Henry, I've talked with Alma and her major professor about her thesis. It's one of those written as chapters suitable for publication. Both told me that the two (of four total) that deal with RRD (then) are the two published in Weed Science with several co-authors. Can your library access Weed Science? If not, let me know. Cutting off an infected cane HAS to be done before the virus moves down into the roots (assuming stem meristem infection) and back out. I've saved several roses from different classes in my yard by catching the problem when only a single leaf node (or three on one side of the cane) were infected in fall. I saved an American Pillar in spring when it was out on a cane about ten feet from the roots. I've never saved a HT, and I've only seen RRD on HTs in spring. That may have something to do with the transmission times in fall to late fall. The one thing that (I don't think) has been addressed is what it is about RRD that ultimately kills the host rose. Epstein and Hill reported a lack of sugar to starch conversion in long infected canes. The odd thing that I watched this year was that some roses I've watched for four years finally got down to scrawney, skinny leaves often with PM and then they died in May (which was not a time of drought or too much rain- just really nice weather.) We know from Glen Viehmeyer and Percy Wright that both saw RRD overwinter in the colder parts of Canada. I don't think we know much about temperature and the whole batch of EMARviruses.

I added what I had on Friday. I can see the addition, but it was never recorded in the number of posts???? Title: "First report of rose rosette disease caused by Rose rosette virus on Knock Out roses in Louisiana." Author(s) : Singh, R.; Valverde, R.; Cook, M.; Owings, A. Author Affiliation : Department of Plant Pathology and Crop Physiology, Louisiana State University Agricultural Center, Baton Rouge, LA 70803, USA. Author Email : rsingh@agcenter.lsu.edu Journal article : Plant Health Progress 2016 No.August pp.PHP-BR-16-0022 ref.1 Abstract : " To the authors' knowledge, this is the first report of rose rosette disease caused by Rose rosette virus on Knock Out roses in Louisiana. It is difficult to assess the total value of roses in Louisiana but this disease has the potential to negatively impact the thriving rose industry in the state."

Google translation of a German paper presented at a meeting. "Infection of roses with viruses with special attention to the Rose rosette virus and Ilarviren Virus-suspicious symptoms such as checks, chlorotic ring spots and line patterns, partly in combination with growth spills and death-related symptoms, have been observed for several years in the rosaceae of a varietal collection. The cause is a variety of plant viruses, which can infect roses. Various viruses (Tomato ringspot virus, Tomato ringspot virus, Tirolo mosaic virus, Tomato ringspot virus) are commonly found as virus complexes in different combinations Roses are most widespread (Milleza et al., 2013). In Germany, the Raspberry ringspot nepovirus (RpRSV) was recently detected in roses of Mainau Island (Bargen et al., 2015). In addition, other viruses have been described in roses, including the Rose rosette virus (RRV, genus Emaravirus), which is widely distributed in the United States, causing considerable loss of yield in all areas of rosaceae cultivation (Babu et al., 2016). Leaf samples of various varieties including tea hybrids, climbing roses, foribunda or polyanthoses with the above-mentioned symptoms were examined for a virus infection by means of DAS-ELISA or RT-PCR method using genus-specific oligonucleotides in connection with sequencing of the PCR products. In the study of 8 rose samples of different varieties with virus-suspicious leaf symptoms, infection with RRV could be detected by the use of generic (Elbeaino et al., 2013) as well as by RRV-specific oligonucleotides (Laney et al RT-PCR can be excluded. Further results of this study on the detection of Ilarviruses are presented and discussed. http://www.schoenmuth.de/Posterdok/Posterdokumentation-PM2016/2016-PST-Halle/2016-PST-Posterabstracts/Posterabstract-PST2016-122a-Stummer_28z.pdf A second link indicates that no rose rosette virus was found. Again from a Google translation: "For a number of years, a variety of virus-suspicious symptoms have been observed in the rose stands of a rose collection in Germany. They are manifested by checks, chlorotic ring spots, and lines (Fig. 1), partly in connection with growth spills and deaths. A variety of plant viruses are to be considered for the infection of roses, a. Various ilarviruses such as, For example, Apple mosaic virus (ApMV), Prunus necrotic ringspot virus (PNRSV) or Tobacco streak virus (TSV) (Milleza et al., 2013). Furthermore, the Raspberry ringspot nepovius (RpRSV) was recently found on the island of Mainau in Germany. (Bargen et al., 2015). Another major virus that infects roses is the rose rosette emaravirus (RRV). It is widespread in the United States and leads there to considerable losses in income in all areas of the cultivation of roses (Babu et al., 2016). The aim of this study was to detect plant viruses, which could be the cause of the observed disease symptoms on the roses. The emphasis was on the detection of Ilar- and Potyviren as well as of RRV. Ilarviren Detection of PNRSV and potyviruses (Table 1) in the ELISA • Confirmation Ilarvirus infection with RT-PCR (Fig. 2) • No detection of potyviruses with RT-PCR • Identification of ApMV in "Pelé" and PNRSV types in the tea hybridomas " Promise "," Climbing New Yorker "and" Parade "by sequencing selected products of the Ilarvirus PCR • Exclusion of the infection with RRV of 8 rose samples of different varieties with chlorotic ring spots, graying or oak leaf patterns as no products in either category or RRV Specific PCR • No detection of the tested viruses in several symptom bearing roses" Also see Table 1. http://www.schoenmuth.de/Posterdok/Posterdokumentation-PM2016/2016-PST-Halle/2016-PST-Posters/Stummer-DPST2016-Poster.pdf
