George:

Thanks for the report. It sounds like it was at or near Route 7 just over the Delaware line.

The multiflora roses are blooming up and down the interstates and rail lines now.... I'm thinking RRD will be spreading pretty quick. I only heard about it last year and it sounds pretty nasty.

That multiflora has been growing for years. So have many, many rose gardens in the area that have not been infected. No need for total panic, just keep out a watchful eye.

thanks George.

I drive along Route 1 several times a week in western Chester County. I keep my eye trained on the bushes on both sides of Route 1 and I have not identified any RRD infected multiflora yet. Of course, watching while driving at a decent speed is not the best way to identify RRD.

I will be driving into Lancaster County over the next few weeks where a nursery owner claimed to have seen RRD on a multiflora last year. I will keep my eyes open for any signs of RRD.

It's been a while since I posted on this forum, but I saw this post and it is a topic of interest to me. I have experienced RRD on my property. I was the first confirmed case in Eastern PA back in 2002. I reported it to a woman in Georgia that is tracking the progression of RRD and she confirmed my suspicions, it was a positive ID of RRD.

I am posting a link to pictures that I took if anyone is interested in seeing what the disease looks like (it still gives me the creeps looking at the pics, yuck!). It was on one of my favorite roses, an Austin rose named "The Prince".

I do not appear to be the owner of that website. Drat.

I"ve got a large climbing rose that has suddenly yellowed and died. What are the symptoms of RRD again?

Carol, the stems grow twisted and red, and the foliage looks distorted. It is sometimes referred to as "Witches Broom". The plant continues to grow. What you describe sounds like it could be vole (little, evil, horrible rodents that eat roots) damage. Did the plant move around easily when you move it? Did you check the roots?

In addition to distorted foliage, you may see swollen stems, stems larger than the canes they are growing out from. In my Yahoo photo album there are two photos of roses in my garden that were infected with the disease. Henri Martin is a moss rose and New Dawn is a climbing rose. I removed these roses and watch others for signs of the disease. Also, I decided not to plant any other roses because of the infected multiflora growing in woods nearby.

Is this RRD? It suddenly appeared this year on eight bushes, all located near a pine tree.

It has appeared in my Philadelphia garden this year too. First as the top of one stem on a knockout rose and then all over an old climber that was on the property when we moved here. I cut the one stem off the knockout and it appears to be fine. The climber will need more than that. I'm going to look up what needs to be done.

Ringaround, I'm afraid that, unless someone has been using a lot of Roundup or a similar herbicide in the area, yes, that is RRD. See the eBook below. The author is Ann Peck, anntn6b here on GardenWeb, and you may want to post a link to your photos on the Roses Forum, Ann will see them.

Loretta5, cutting off that one stem might not be enough. See the eBook.

With RRD, is there red watery substance at the top of the red leaves in the morning dew? It looks like my bush has RRD, and I have noticed early morning, red water dripping from the very inner top of leaves dripping on other leaves.Cecil county is right at the PA./DE. line.

Diane-nj you were so right. Cutting the bad stem off was of no use whatsoever. The disease has shown itself again on the knockout and on a Rosa Glauca nearby. They are both slated for root pruning. Too bad because I love having both of these roses in my garden.
