Has anyone ever dealt with Rose Rosette Disease?
Comments (17)OK, so it's Memorial Day and I'm really hoping someone is around to help, since I need an answer by tomorrow morning. (Yes, I'm a terrible procrastinator, LOL!) First off, RRD was definitively diagnosed by the state university plant pathology lab in both my climbing pinkie and in a sample I took from a multiflora rose on my property. We are having the fields around our house that are full of infected multiflora bushhogged tomorrow evening. Based on information I have gleaned from this forum about alternative ways of combating RRD, I have purchased sulfur and wilt pruf. I was planning to mix it all up and hit the roses with it first thing tomorrow, then cover them in plastic (clear plastic painter's dropcloths) and hope for the best while the fields get mowed and for a few days afterwards, in the hopes of keeping any mites that are disturbed during the bushhogging off of my garden roses. But I have some questions: 1) It is supposed to be 80 degrees tomorrow - too warm to spray sulfur? I have a powdered sulfur from Bonide that I was planning to mix with water. It's been an abnormally cold spring here and today was the first day it hit 80 degrees. I had planned to spray on Saturday, but the weekend got away from me. I have read that you aren't supposed to spray it when it's warm, but it doesn't say exactly what happens or exactly how warm is too warm. Also, considering I am planning to cover the roses with painter's plastic dropcloths, you can probably figure on a greenhouse effect that will make the temperature at the roses much warmer than 80 degrees. 2) The roses are just starting to bloom - it's the beginning of the spring flush. Will spraying with wilt pruf and/or covering the roses with clear painter's plastic dropclothes screw up the blooming or hurt the plant? 3) Do I need to do all these things (wilt pruf, sulfur, and plastic dropcloths) or can/should I leave something out? I don't want to make things worse by doing something I shouldn't.... Thanks very much!...See MoreRose Rosette - remove seemingly unaffected neighboring roses?
Comments (4)No herbacide anywhere near these roses, so I am certain that's not it. The roses were not dead, but they had been in decline for the past several years and would have 1 or 2 deformed canes (witches broom) as well as splotches on the canes. At first, I just thought it was a rogue cane or two and would trim them off. But, RRD is getting to be big news in North Texas, so when I became aware of it, I realized that's probably what it was. If I do keep the two roses in question, I will definitely need to move them to a sunnier location. I have a spot where I'd like to put them, but it is near another bed with healthy roses (Knock Outs, Valentine, Lamarque). Thanks for the advice....See MoreFirst report of rose rosette disease caused by Rose rosette virus on K
Comments (6)I added what I had on Friday. I can see the addition, but it was never recorded in the number of posts????

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."...See MoreRose rosette disease or not?
Comments (14)Thanks, everyone. It's comforting. But something's DEFINITELY going on - can you help me figure out what? here are my concerns: 1. On a hybrid tea rose, a bud is typically at the very tip of the stem. Here I suddenly have multiple mini-stems with buds branching out of the main one. It's uncommon. 2. Buds are kind of small. 3. The leaves on the affected branch are different - darker, shinier and more leathery - see the photo of the leaves next to the healthy ones. 4. BOTH affected plants are Fragrant Plum on a bed of hybrid teas, no others are affected. So...can there be another explanation? I've sprayed very generously over the last few weeks because we had frequent rains and I was concerned things might get washed off. Could that be the reason? Then why only one branch? Do you have any ideas? Alternative explanations to this thing? Thank you all very much....See MoreMelissa Northern Italy zone 8
