Henry,
That is good information considering RRD is wiping out Knockout roses. I see it on plantings all over the place.It looks like the Knockouts will get knocked out!
Our Rose Society went on a garden walk at the University Of Illinois gardens. One of our members saw a big planting of Knockout roses. They were all infected real bad. The Horticulturist in charge didn't know what it was!!!!!! They are removing them because the Master Gardeners have a rose garden less than a 1/4 mile away!

I hope that they were able to rule out herbicide damage by having at least one tested.

Henry,
If it was herbicide it would show up on other things too.But this bed was in a turf area off a sidewalk area and no Roundup used. When I saw it it had been on the plants for a few years. These plants were neglected.
I am seeing it all over town on Knockouts.My neighbor has a pink Knockout and I am keeping an eye on it!

Turf areas often have yearly weed and feed type applications.

The link below leads to the 2 videos (part 1 and part 2) that discusses the herbicide - rose rosette virus confusion problem.
