Fungicides/pesticides and "is there help for this tuber?"

[Karl-Otto Zita]

Don`t use strong pesticides as they are not safe at least fore =yourself.There is a safe and good thing like charecoal.

Cut the tuber cleen from all rotten parts and powder the wound with =pulvericised charecoal.A better site will help it to survive.

AEG,
I could probably find the answers to my questions by exploring the =archives where there is a lot of great info, but I will go ahead and ask =anyway in hopes that my Arisaema ignorance is not too obvious.
I live in the humid south (Chapel Hill NC, Zone 7a) and deal with a =lot of heat and humidity problems.  I have recently acquired a =speciosum, which I proceeded to place in the ground instead of potting =it up like my other Himalayans.  Well, it proceeded to dwindle and =looked particularly poorly.  Yesterday I decided to dig it to see the =problem and lo and behold, I had rotted 2/3 of the tuber away with not =good enough drainage.  My questions are as follows:
What pesticides are safe and how to use them on Arisaema =(and other aroids for that matter)?
What pesticides are safe and how to use them...?
Can this tuber be saved?
There are multiple buds that appear viable on the ="unrotted" side, can these be sliced off, with as much viable tuber as =possible and doused with fungicide (which one?, see above), and I would =end up with some small plants?  Or should I say "goodbye" to this tuber =and move on?

Thanks in advance for your help.
