| Hi, I've had this (sorry for the lousy pictures) what appears to be mosaic virus on about 3 rose bushes that are anywhere from about 15 years old to over 20 years old. All these bushes are very prolific. Lots of roses every year. This year with the hard winter, cooler, rainy summer hasn't been real kind to my bushes. All of them have lots of buds, but not warm enough to get them opening in a faster basis. New Love Song is a disappointment to me (3 weeks of not one sign of a bud). Anyway, I've dealt with this what appears to be mosaic for 15-22 years on these bushes (just seems to be maybe a little more so this Summer). Mosiac?? Thanks! |

| Another pic. I really need to invest in a Smart phone instead of trying to take a pic on the computer camera. |

| I doubt this is virus. You know the pictures aren't clear, but I haven't seen virus look like that. Turn the leaves over, and see if there are bright orange spots of rust on the underside. If you have a flatbed scanner, you can scan the leaves, top and underside, to give us a good image. |

| From those images it does look like rust instead of RMV. Your flowering issue is most likely the lack of heat. I've seen Love Song locally at a great nursery down the Boulevard and it is spectacular. Loaded with flowers in the high heat and healthy as it can be with no spray. Of course the climates are totally different, but Love Song definitely appears to enjoy the heat. Kim |

| Sorry, we don't have a scanner. These are basically lots of yellow streaks or dots on the leaves. NO orange or rust color on the any part of the leaves. I know it's not blackspot because we get that too, but more so in Fall. |

| Looks to be like inch worm damage, check the undersides of the leaves for small green worms that skeletonize the foliage from the undersides of the leaves.. Definately not mosaic... Steve.... |
RE: Mosiac virus?

| The leaves are not skeletonized at all, and no sign of any worms or bugs. I always thought (from pictures) that the mosaic virus had streaks of yellow through the leaves, no? |

| There are now around 20 or so known viruses that infect roses. Perhaps one of the Universities that are looking for new rose viruses would be interested in looking at a few leaves. In Wisconsin possibly Professor David Zlesak would be able to tell you if they are of interest and where to send them. http://www.uwrf.edu/FacultyStaff/1840024.cfm |

| Nick, are you growing this inside or did you just bring it inside for the photo? |
RE: Mosiac virus?

| seil, all my bushes are outside. I cut that off & brought it in so I could take a picture (albeit, a lousy picture) of it from my computer camera. |

| Nick -- if what you saw underneath looked like rust -- yea, they're likely RUST. Let me just say -- I REALLY HATE RUST. I can live with a rose that mildews some -- particularly when it's immature. I can live with a rose that rusts on old foliage, whose time to go has come. I cannot live with a rose that rusts on new leaves. We do not spray. So, when a little rust turns up, particularly on older leaves, I remove those, and put them in the trash can. The plant grows new leaves, and everyone is happy. But when I encounter a rose that just rusts all the time -- that rose, I remove. There are so many roses that don't do that, why live with those that do? (JERI) |

| I've lived with it on the two red rose bushes (maybe Lincoln?) that are about 15 years or older because they give such luscious, gorgeous, florist style red roses. Usually, I get tons of red roses despite this problem. That's why I'm not ready to dig them out if it is indeed rust or whatever it is. I think the Wisconsin winter was harder on all my bushes, although they all rallied back. |
RE: Mosiac virus?

| Well, sure. We all just have to decide what our own tolerance level is. Shoot, I've pulled ALL the leaves off some blooms, and made bouquets using ferns for green. Worked for me. :-) |
