Re: [Aroid-l] Hot Water Treatment for Nematodes in Amorphs

From: George Yao <gcyao at mydestiny.net> on 2007.03.30 at 14:26:45(15528) Allan, To avoid the need for accuracy is another reason why I wanted to find out how high a temperature Amorph tubers can take. If they can take much higher temps, then I won't have to worry about putting up a good setup. Aside from that, one source says that at higher temps, shorter treatments are enough for the same efficacy so much so that at 60 degrees centigrade, only 3 minutes is needed, which will be so much more convenient. Bernhard, Thanks for the info. That's a wake up call that I should consider size.

Thanks, Allan "StroWi@t-online.de" wrote: Dear George, a standard treatment to cure dormant Hippeastrum bulbs from mites (Steonotarsonemus laticeps) and a fungus (Stagonospora curtisii) is 46 °C for 2 hours; since Hippeastrum bulbs can be quite big in diameter it might match Amorphophallus. Good luck, Bernhard. -----Original Message----- > Date: Tue, 27 Mar 2007 07:22:08 +0200 > Subject: [Aroid-l] Hot Water Treatment for Nematodes in Amorphs > From: George Yao > To: Discussion of aroids > Hello everyone, > > My Amoph collection was hit by nematodes last year and I tried > Furadan with mixed success, so I am now going to try using hot water > treatment.
