The issue is not to create a panic over RRD, but to spread the word. A lot of people don't even know there may be a problem, but that has changed since Ann published her eBook. The link Margie provided is the revised
eBook and was published in 2007.
Before she wrote about RRD, it was almost a secret that only a few experts knew could be a problem. RRD research was not a priority, so not much was known about it and not much was shared with general rose gardeners. They didn't even know what to look for to determine if a rose was infected.
Her eBook was one of the very first publications that stated that ANY rose was susceptible to RRD. For a long time, it was believed that only multiflora was susceptible. That has been proven not to be true in the last few years.
wrote a post a while back where she visited a public garden and the curators of that garden did not even know that many of their roses were infected.
Publication of information about RRD was not published in the media or even in articles of rose publications. Nursery sites never mentioned the possibility of a rose getting infected.
The US Department of Agriculture finally provided a grant to study RRD as it became more evident that it could no longer be ignored. Roses are considered a specialty crop in the US.
Since 2013, scientist and industry leaders have met annually to share information and to speed up the learning curve. Now, if you Google rose rosette disease, you can get a LOT of hits. The information is becoming more public.
The sites I posted in this thread
are all industry publication sites except for one
and that site is sponsored by Star Roses, one of the largest rose distributors in the US.
The fact that they have found RRD in the growing grounds of Weeks Roses, is not common knowledge. Weeks did send a letter to their vendors, but they do not know how long RRD has been in their growing fields. The rose where they found the infection, was supposed to be RRD resistant, 'Top Gun'.
That tells me that they still haven't figured out how to really test if a rose is resistant.
When a rose is infected, every cell in the rose is infected. So far, they believe that RRD will kill a rose within about four years.
The biggest problem of keeping an infected rose in your garden is that RRD is spread by mites and CAN infect other roses in your garden.
Is Sharon's method of handling her roses the right way to manage RRD in a garden. I don't know. What I know, is that I am too dang old to have to dig up roses and don't even want to go there ...
Is removing the rose as soon as you see symptoms the best way to manage RRD in your garden. It's the most cautious approach and for me, would be the best approach.
What's important to me is that people learn what the symptoms of RRD are and what they need to be looking for when they check their roses.

I check roses regularly and I have seen RRD. I have also seen my roses get some symptoms but not all. Such as excessive thorns that remain green, and excessive twisted cane growth that looks partially normal but coming out of the top of a hybrid tea. I do not believe all symptoms have to be present to be RRD in the early stages. Kind of like when we get sick. Start with general aches, fatigue, headache, fever, cough etc. Adding up to the full onset of the flu.
This is what is important. People need to check their roses and they need to look for problems associated with RRD.
At this time, there is no test for RRD. Symptoms can show up within a few weeks of infection or not for two years or more.
I am waving the red flag about RRD to increase awareness.
If something looks "off" with a rose in your garden, it's important not to ignore it. It may be nothing. It may be RRD or it may be something else.
Until more is known about RRD, I think to minimize the possibility of having RRD in your garden is a mistake.
