Re: Rot Prevention

From: magrysbo at shu.edu on 2001.12.12 at 00:50:07(7887) It was a 1% solution on only several tubers, mostly Arisaema, that had been dug up for storage, and were rotting out despite application of other compounds. These tubers have no live roots during dormancy and survive kept absolutely dry. +More Bonaventure Denis > cc: Sent by: Subject: Re: Rot Prevention aroid-l@mobot. org 12/11/2001 04:15 PM Please respond to aroid-l The great thing about hydrogen peroxide is that is a good topical disinfectant and it is applied, does its thing instantaneously and then breaks down in the process into water and oxygen. No obnoxious organic molecules to pollute the environment (or if you are a nurseryman poison your workers). As far as treating Amorphophalli tubers with it, it is non specific in its action and will take out the good microflora as well as the pathogenic organism. It would be ok if you suspect rot problems are happening or going to happen. However, I would not want to start wipe out the equilibrium that exists in the Amorphophallus root zone around the rhizome. If you are going to all the trouble of dipping the pots in the stuff you might as well just bare root them and store them in an inert material that does not support rotting. But then again I don't do much with Amorphophalli and so what do I know.
