Re: [aroid-l] Amorphophallus tuber disease

From: "Scott Taylor" staylor at brevardparks.com> on 2003.02.17 at 20:59:46(9989) Rand: Thanks for your reply.. so this technique (sulfur) has worked with paeoniifolius also? Because I have actually cut away the necrotic tissues and treated it with a fungicide paste, only to have the disease progress.. Is sulfur considering fungicidal? D.

This is applied before planting and after being dug up and dried. The tubers do not rot and varmints do not nibble at them. If a tuber is dug and there is a "soft spot" on any of them, I simply cut back to good flesh, dust the wound and let it dry. If not badly damaged the tuber will usually sprout again and form a new healthy tuber. They are stored cool and dry, except an Amorph. konjac (cleaned but untreated, sulphur being what it is), which I often use as a paperweight on my desk just to make people ask questions. Plus, it is interesting to watch the thing slowly start up at the growing point when it decides to do so.
