Thinking this is RRD? Thanks

First thought is yes it is but once I blow up the picture the details are washed out so hard to say if RRD or possibly something else.

Thanks, best shot I could get.

Could be spring dwarf disease since I don't see any super thorns which comes with RRD.

I think it looks a lot like herbicide damage.

Probably.
Rip it out, burn it and douse the are with mite killer.

They don't use any herbicide, it's has looked like that for the last 3 years, had the intense red color a few years back

If it is RRD, it is a mite breeding area which means the wind will carry mites and misery to other areas.

Is it the only rose affected after 3 years?

It's not RRD if it doesn't have super outrageous thorns all over according to a highly respected master gardener who was trained to identify it. If it's spring dwarf disease, all you have to do is to trim that part off.

Thanks

Thought this was interesting

It looks like an adjacent one is also having issues

He/she is wrong.

What does an infected plant look like?

There are several symptoms that a rose infected with RRD may exhibit:

Bright red new growth that never turns green
Very thick stems with excessive thorniness
Flower buds emerge in tiny, tight clusters
(these are the "rosettes" that gave the disease its name; they are also called "witches brooms.")
Flowers that open are deformed and stunted looking
Foliage is contorted and stunted looking; may also be yellow

A rose that is infected with the disease -- may have only one of these symptoms, -- or it may have any or all of them. The symptoms may be confined to just a few shoots or part of the plant, especially at first. Symptoms may appear any time that the rose is in active growth, but are most likely to be seen in the early to middle part of rose season.

This is what spreads it:

common name: eriophyid mite vector of Rose Rosette Disease (RRD)
scientific name: Phyllocoptes fructiphilus Keifer (Arachnida: Acari: Eriophyidae)

This mite can be spread by the wind and by contaminated clothing and equipment. It also is possible that it can disperse through phoresy (attaching itself to insects). As a result, the distribution of the mite and RRD is expanding.hat spreads it:

re Spring Dwarf Disease, from what I have read the recommendation is to remove the plant.

Whatever it is, I would be inclined to remove the plant. It is no longer a thing of great beauty.

I agree.
When I viewed the photo provided, the first thing I noted were what appeared to be elongated leaves - distorted leaves.

I hate to interject into this topic but I was reading it and I thought oh my that sounds like what is happening to a couple of my plants. The photos are of Heptacodium Miconioides or Seven Sons.I have had mine now going on three years. Right now it should be leafed out but look at the photos! In place of the leaves are these tiny little clusters of green growth. Could this be the disease that is being discussed ? Thanks

While I'm unsure of the roses exact problem I would be inclined to remove it. Three years is patients indeed. Does the rose exhibit normal growth anywhere or later in the season.

Just wanted to share an experience I had two years ago. When coming home from Hy-Vee a grocery store with a spring plant center. Every year I'd usually get a rose or perennial. Anyway there's farmland right across the road from the store. With 30 mile an hour winds blowing they were spraying the fields with ammonium nitrate mixed with roundup. You would not believe how far that stuff was blowing. So is sort of possible to receive a hit of herbicide without realizing it,

Anyway after three maybe it's time to say goodbye. My opinion only is that the rose would look much worse then that after three years of rrv. Good luck to your friends.
