  Amorphophallus tuber disease& sulphur
From: Rand Nicholson writserv at nbnet.nb.ca> on 2003.02.18 at 03:44:45(9992)
Scott;

I do not have paeoniifolius unfortunately(I only wish), however I do
have various species of bulbs, tuber and rhizomes, aroid & non-aroid,
and have used sulphur on all of them for fungal and bacterial disease
with a good amount of success. Fungus can be difficult inasmuch as
you need to get all the mycorrhizae out of the tuber as the sulphur
will only act on the surface of the cut part. You may need to cut
deeper into what appears to be healthy flesh and drying the tuber
(the newly cut surface) fairly quickly in low humidity has also been
important in my experience. Perhaps there are others here with
hands-on experience with paeoniifolius that may wish to chime in?

Hi,
I noticed that you mentioned "Mycorrhizae" as the cause of the tuber rot. I
am not aware that the mycorrhizae fungus has a negative effect on tubers or
roots. If it does, I would like to know about it. Ron

Hi Again:

Oops. Good eyes Ron. That should read "... you need to get all the
_mycelia_ out of the tuber ..." , that being the vegetative part of
the fungus consisting of fine threadlike hyphae that can invade good
tissue and help break it down incurring further necrosis.
