I usually recommend that people take diseased rose material to the trash.
 This is because many folks don't compost at a high enough temperature or
for a long enough time.

Also, I think Dr. E mentioned previously that rose canes take a long time
to decompose. It helps if you run them through a chipper/shredder, but
then that's another piece of equipment that a lot of folks (like me) don't
have.

We don't remove all the organmic matter from the ground around the roses.
that's food for the fungi,

But we have to make sure that the fungi that use the dead plant material
are
the beneficial fungi, not the disease fungi. So, the trick is to inoculate
the dead plant material with the beneficials, and get them growing, not the
diseases.

If you use AACT, then you reduce the disease on the leaf material, and
managing the dead litter material is less tricky.

Total sanitation is the way IPM has to work right now, because they still
kill off all most of the beneficials. We all know how impossible total
sanitation actually is, so doing something about the disease burden using
compost or
tea on the litter - even a couple time if you have really bad black spot -
and
reducing disease through use of the tea, coupled with sanitation of leaves
that
escape the tea spray and get diseased, works well.

Removed plant material should be put in a compost pile THAT HEATS PROPERLY.
So, if you aren't willing to make sure enough high N is added to the pile
to
get adequate heating, then you will need to compost with worms, who also
take
out the diseases. Or compost for a couple years, making sure the pile is
occassionally turned so any disease gets well competed against by the
complex set
of biology that should be present in a good compost pile.

If you throw organic matter in a pile, that doesn't mean you are
composting.
If the pile starts to stink, you may well be helping the diseases grow
faster
and better than the good guys.

Sanitation is a good thing, but it is far from our only tool against
diseases.
