Wash the damaged or bacterially invaded mushy spots with soap after
debriding the diseased tissue.   Historically what was useful with irises=is
to clean and scrape  the area using  a spoon or similar tool down to what
appears to be untouched tissue and pack the area with something like Come=t
or a similar kitchen cleanser that releases chlorine when moist-- to kill
any bacteria left in the surface area.  This will also dry  the area
thoroughly and help the plant to form a callus to block further invasion.

Presoaking the tuber with an aspirin dilution of one 325 mg aspirin tabl=et
per quart  might also help since it probably will stimulate the plant's
immune system.  There is no reason for not using a 2x stronger dilution b=ut
no information on whether it would help.   I have not yet been able to sa=ve
an arisaema tuber with this, but then, I probably did not debride enough =of
the diseased tissue on the species I treated.    It would have left nothi=ng.
I should have taken off the developing buds and kept them.     (dahaiense
tubers --2001)
