Re: [aroid-l] Amorphophallus tuber disease& sulphur

From: "Ron" ronlene at adelphia.net> on 2003.02.18 at 15:47:38(9995) Hi, I noticed that you mentioned "Mycorrhizae" as the cause of the tuber rot. I am not aware that the mycorrhizae fungus has a negative effect on tubers or roots. If it does, I would like to know about it.
