Hello all. am very much inclined to agree with Eric on this. The =
likely bacterium is probably similar to Erwinia carotovorum. Once the =
infection has started it is nearly impossible to cure. I would dig it =
up, examine it carefully, scoop out any soft parts with a clean =
(sterilized) sharp-edged spoon--or curved knife noting the =
discoloration, and then take out any discolored part that is not soft. =
Then pack the cavity with a chlorine-releasing scouring powder, such as =
Comet, and set it aside to dry.
Examine it in a week, wash out the scouring powder. If there has been =
no further advance of the infection, (assessed by the change in =
coloration having advanced to unaffected parts of the tuber)--set it =
aside, replant it or treat it as you would, if it had not gotten =
infected. Then cross your fingers and hope. Sometimes this works. This ==
works well for iris rhizomes, which also require being set in direct =
sunlight for a month or more . This will sometitmes start the =
develoment of accessory buds which guarantee further potential growth. =
I don't know whether this would help for arisaema.
The reason the infection is nearly impossible to get rid of, is because =
the bacterium releases a toxin or enzyme and spreads itself in advance =
of where it appears to be, visually . If the tuber is big, and has any =
accessory buds on it, your chances are better than if it is small and =
has none.

Most likely it is a bacteria infection. I got a tuber of 20 cm in =

not treated well (damaged with the digging it out). It got soft and =
rotted, but it lost only the outside of the tuber and a much smaller =
tuber was left of about 7 cm in diameter that survived and flowering =
every year.
Maybe it is better to get it out of the soil and leave it to dry. I'm =
not a specialist in growing, but it worked for my huge tuber.
