Dave if it is RRD my commiserations.

Around here it is a rural disease and
will absolutely decimate entire stands
of roses.

Though it seems really surprising that you have it.
RRD mites spread by wind so there has to be
continous trail of roses within a few hundred yards
all the way from your garden to the rural infection.

In KC the surrounding prairie is absolutely swarmings
w/ infected Multiflora but disease inside the city is
almost unknown.

The other thing that surprised be is the 'witches broom'
had buds and blooms on them. Never thought that was possible.

The real bummer if it is RRD is that you not only must find
the plants in you garden that are infected but also the ones
in the neighbhorhood that brought the disease to you. Those need to be
exterminated as well.

Heres to hoping its NOT RRD.

I'm rather down about it at the moment. I'm assuming that this 20 foot
rose bush has to go, right?

Please, somebody tell me I'm wrong.

Please.

Hi Dave,

You may not have to remove the entire bush. Have the symptoms just
recently
appeared and have you just noticed the disease on this one cane? You may
be
able to save your rose by removing entirely the one infected cane - burn
it
or wrap it tightly in plastic before throwing it out. If it is too late
to
save the rest of the plant, you will know soon enough as this disease
spreads rapidly. If you notice any more symptoms after removing the one
infected cane, you will have to remove the entire plant, disposing of it
as
described above, or your other roses will be at serious risk.

The problem after that remains concern over the mite (Phyllocoptes
fructiphilus) that transfers rose rosette. It is not affected by
traditional miticides. You must use a systemic insecticide/miticide
containing dimethoate, not an attractive option if you are an avowed "no
spray" person.

You have my deepest sympathies as this is definitely a dagger in the
heart
of anyone who grows roses. I'm going to hope you caught it in time to
save
your valuable mature climber.

Mike - thanks for the advice. Same goes to Cass. I've contacted Ann
Peck and am hoping for an answer soon.

I'm really hoping for the NEEM oil abuse scenario. I'd really hate to
lose this plant, not only because it will leave my fence bare, but it
will be a real mess to remove. Plus, I'm quite fond of it as it was my
first rose planting.

Here's a question about the mites (if it turns out that this is indeed
Rosettes). Should the first frost have taken care of them (last night
we got our first deep frost)? If so, can I assume that my upcoming
dormant spray application would also take care of them until spring?
