Neal, I read with keen interest your article. It is so informative and well put together. I am hoping that someone will find a cure for RRD soon!
Unfortunately, I too know the heartache of losing a rose to this terrible virus. Never knew the name of it, but it was given to us when we first moved into our house 36 years ago by my husband's uncle as a housewarming gift. We had to destroy it last fall. I had taken cuttings from it several years ago and have another bush across our yard and am hoping that it is not infected.
