In my case, the pathology report in one case was negative and in the
other it reported a couple of different funguses.

respectfully "if the paeoniifolus will not respond to fungal treatment
then does that not eliminate in part the very question and we are
looking at a true virus of some nature? What were the results from
the pathology lab?

I have posted previously a couple of times about similar problems I
have had with paeoniifolius, and based on those communications I have
surmised that it can be a 'problem' species. Now I am
wondering/hoping that some clones are maybe less subject to this
disorder. I have had ongoing problems with 'rot' in this species,
particularly with larger tubers. I have tried cutting away the rot
area and treating with fungicides (I have tried Captan and Mancozeb).
I have also tried sulfur and treating lesions with bleach: sometimes
this works and sometimes not: often the rot will continue until much
of the tuber is consumed. Oddly enough, when I get rot on konjac,
the simple cutting away of the lesion seems to solve the problem, so
these two species seem different in this regard. The recommendation
I have had is that damaged tubers not be replanted, and also do not
reuse planting media. A well-drained media is also supposed to be
very important. I have tried drenching the soil with Mancozeb
throughout the growing season, and this really didn't seem to help;
my suspicion at this point is the the problem may not be fungal in
origin: in fact, I have sent two different samples to path labs with
no definitive results. This remains somewhat of a (frustrating!)
mystery!!!

If it is injured or sick it finds its way to my house.
Paeoniifolius Bulb, received from my friend, appears to have an
injury from possible digging instrument used for its removal. It
has been out of the soil for about 4 weeks. The gash is about 7"
long and 4" wide. Ya it is a nice size one for sure. I have used a
spoon yesterday 11-14-04 and removed the "Mush" and "decay", and
some seemingly discolored tissue up to the point of clean healthy
flesh. I would like to save this bulb if possible. There is a few
spots remaining which appear as slight discoloration ( dark spots )
but still, "semi firm" that would require deeper and more radical
tissue insult to remove. I would say that I extracted a good 15% of
the bulbs mass. Is there anything else which I should do other than
say a prayer? Is the extraction of the decay the proper means to
save the bulb? Is there a wonder application to end future decay?
The soil the plant was in, is it considered contaminated? My
suggestion to that was, " dump it and avoid the risk of any possible
contamination ".
Thank you
