Ok, Patty, you are my hero three times running!!!! I was ready to dig up the rose. We have had extreme heat early in the season. We have just been declared a drought emergency in our county. I have been watering deeply once a week, but I remember that this rose got better when I watered it from above, thinking it was mites. It may be that the emitter to this rose and the other one is clogged. They have been in place for 15 years and I last year I put wood chip mulch on top. I am certain you are right. I am going to give all these a dose of Super Thrive, check the hoses and water twice a week until the heat gives up. We have 100's forecast for a couple days next week. The rest are 90's. These are on the east side of the house, but the heat gets intense anyway. Thank you so much again!!!!

rmv?

RMV was my first thought, rifis. But I had one a little ways down with the exact symptoms, but less severe. I'm going to check the emitters before I take out the rose.

I immediately thought of RMV. It can show different patterns, not just the zigzag lightening look. So I'll bet my money on that. Diane

That looks very much like rose leafhopper damage to me...

Stippling is the name of the pattern of the damage to the leaf and it is usually caused very small insects feeding on the underside of the leaf. In my area it most likely caused my spider mites, but as Henrik said, leafhopper is another possibility. Look on the underside of the leaves and you may see the culprit.

I had the exact same thing in my Clotilde Soupert. We hadn't had any we had a heat wave. I look for pests and didn't find any. I gave it a little extra water until the rains started again. It started growing new leaves and has bloomed since.

Rebecca,

Just to explain my reasoning thou I maybe quite incorrect. I did not blame leafhoppers because they are on all of my roses. But never has that leaf damage ever shown on but a few roses each year.

I discounted rmv because to date there have been no reports of a healthy rose for as long as you have had this rose suddenly becoming symptomatic. If a healthy rose has picked up rmv that it never had. This would be devastating news and I've not read about it happening yet. Oh and don't forget your mother plant is totally healthy.

As suncoast mentioned the roots temporarily were not feeding her rose hence the damaged leaves.

This does not mean I'm correct but I have had roses with the exact same look. First thing I thought of was rmv. All of mine where own root and once the roots were more established on mine. It went away. You have some absolutely excellent rose resources in Minnesota. I'm certain they would share their thoughts with you.

Thank you so very much for all your VERY HELPFUL suggestions and comments. I do believe it is the heat we have been having here. I checked under the leaves and hove found no insects of any kind. I think if it was an insect, the surrounding roses that are touching this rose would also be affected and they are not. The mother plant between the 2 affected roses is not affected.

On close inspection of the rose, I noticed that it is getting some new growth that is not affected. I am thinking it is a clogged emmiter and since I have been watering it from the top, it is getting more water and is recovering.

I learned so much through this whole post about all the possibilities, and I thank you all for that. I know now what to look for the NEXT time something happens to my roses. I am copying this entire post to my notebook on my iPad for future reference. And, I am off to check my emitter. :)

Concerning whether it has a virus. There now are 11 or more - I think I have seen references to about 20 - besides my web page) viruses identified that infect roses including at least one that is spread by aphids. The normal rose immune system against viruses is temperature dependent (better at higher temperatures).

This link states 11: http://ceventura.ucanr.edu/Gardening/Coastal/Landscape_578/Viruses_Menu/Rose_Virus/

My web page lists 20

The following is one that is spread by aphids:

Thank you again Henry. One of the pages did not load for me but it may just be quirky at the moment.

Some of my roses look the same as Rebeccas with mottled leaves, Madame Hardy being hit the worst. For the last two years in Spring the leaves are perfectly healthy, then branch by branch they all become a spotted white and wilt. I cut them back severely after the blooms are gone. The closest identification I could find was a photo of a leaf hopper plague.

My guess could be wrong, whatever the problem it is, I find it extremely distressing because no treatment with expensive natural sprays have been successful in the least.

Also oddly, Evelyn next to Madame Hardy is not affected, but Autumn Damask on the other side is terrible, who knows why.

Berrypie, that is my experience exactly! My leaves didn't wilt, though. I'll keep track of this thread and keep you posted on what happens.

Rebecca

Roses totally recovered with added overhead watering!!!!
