TUBER ROT

[Adam Fikso]

This sounds as if  it would be quite effective because the cement, being
strongly alkaline, would sterilize the area.  I have used (for other kinds
of plants) dry Comet (or similar chlorinated scouring powder) in a similar
manner; with chlorine freed up by the moisture of the rhizome  acting as a
sterilant to the affected area., in case not all of the infected  tissue was
removed.  This is sometimes useful  because in infections by Erwinia
carotovora, the enzyme produced by the bacterium  invades healthy tissue and
lyses it, invading and destroying tissue ahead of the actual organism.

I have not tried this with arisaema yet, but may. Adam Fikso in Zone 5a
