Hi Daisyl.
I looked at the images on your web page, and I haven't seen anything like those symptoms -- clumps of mangled growth with closely-spaced, smallish thorns; bright red foliage and stems; die-back. I suppose it's possible my particular roses are exhibiting RRD symptoms that are not the norm, but removing all of them is a solution I need to consider carefully. I'm old and couldn't do it without help, so the work would be quite expensive.
Other questions/facts:
A member asked if I had any photos of leaves. I hard-pruned them three days ago, so no recent photos of leaves. I've uploaded a pic of half the rose bed from last summer. There's a Peach Drift next to the rock, and the three roses ahead are the ones with the strange sprouts at the roots.
I have about 18 Iceberg Roses (only one neighbor has them; most neighbors have no roses). They show no signs of disease. Are they not susceptible?
I don't have any Knockout roses.
Three years ago, I hiked a narrow trail bordered with wild roses (south County San Diego), probably multiflora (single, white flowers). If they were infected, could I have brought the mites home on my clothing?
If this is RRD, is it possible the mites were present in the nursery stock when it was purchased seven years ago? "Multiflora rose is sometimes used as rootstock for propagating other roses..."
Thanks,
GD
P.S. Just remembered: I also have two nearby Rosa banksiae (white) which show no signs of RRD.
