There is no such thing as an RMV resistant rose. If you graft an infected
root
to a healthy cutting, it will be infected.

True.
I assume they meant virus free stock.


I didn't assume that at all. We do use the term disease resistant when
referring to either blackspot or powdery mildew so it seems logical to me they
meant there were RMV resistant roses.



RRD is caused by a mite. And there is an insecticide which kills the
mites
that spread the disease. See Ann Peck's site for more details.

Its not 'caused' by a mite, its spread by it.
But no one knows the cause really. probably a virus.

You're right on this one, it is SPREAD by a mite, not caused by. That was
definitly my error.
