Help!!!!

From: "Eduardo Goncalves" <edggon at hotmail.com> on 1999.07.14 at 22:07:41(3504) Dear aroiders, I need EXTRA-urgent help! As some of you already know, I am living in Sao Paulo now, but my living collection is in Brasilia (more than 1000km far).I use to check my dormant tubers once a month (seldom twice) to see if they are up. They are usually kept in boxes in my closet, in my house in Brasilia. For more than 4 years they are kept there and everything was alright. This year I got some tubers in Brazilian Southern Amazonia (Taccarum weddellianum, Dracontium ulei, some rare tuberous Xanthosoma, etc) and placed them in the same place. Suddently, a white fungus started to grow everywhere in my tubers. They are eating ALL my dormant plants, including those very rare like Taccarum warmingii, Xanthosoma aff. eggersii, X. platylobum, Asterostigma cryptostylum, A. lividum, Scaphispatha gracilis, many morphospecies of Spathicarpa and many others. The fungus grows like a white cotton, mainly in the top of the tubers. I am very affraid, because I dont want to lose them. I have never used fungicides like captan before, because Brasilia is very dry during the dormancy season and it never happened before. Please, is there any way to solve this and SAVE my plants? All suggestions are welcome! It is new to me and I really don't know anything about it. Best wishes, Eduardo. +More (a hopeless man from Brazil...) ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

(a hopeless man from Brazil...)< Dear Eduardo, Sprinkle and spread Captan all over them right away! I have NEVER had any bad effects with captan at ANY concentration, even in water and on seedlings. It should save your tubers IF it`s only a fungus! Good luck, Julius +More ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Please, is there any way to solve this and SAVE my plants? Eduardo - +More Dusting the tubers with sulfur powder might be a solution, but I don't know how accessible that might be, or whether it would cause any damage itself (I don't think that it would). I would recommend waiting to see what other aroiders might suggest, but this is a possibility. Jonathan Ertelt

From: Aroideae at aol.com on 1999.07.15 at 05:14:45(3513) Dear Eduardo, Since both are simple things, readily available, you might try a direct application of hydrogen peroxide (I believe the retail 'grade' here is 3%) followed by an application of cinnamon and/or powdered sulfur. A good dose of direct UV from the sun wouldn't hurt either!! Best, Lynn

From: Douglas Ewing <dewing at u.washington.edu> on 1999.07.15 at 13:51:10(3515) I am having success with liberal dustings of ground cinnamon on fungal pathogens of many types. I trimed a rotten portion off of an Amorph. tuber and applied the cinnamon- it stopped the rot right away. smells good too.

From: Newton <Newton at coiinc.com> on 1999.07.16 at 18:51:15(3521) Since I first heard about using cinnamon as a fungicide right here on our very own aroid-l, I have used it EVERY fall by liberally dusting all the aroid bulbs/tubers that I store for the winter. When I find one come out of the soil with occasional rot, I cut or scrape off the rot and apply the cinnamon directly to the flesh and that ends the problem. I have never lost a tuber to rot after I applied this simple treatment. Thanks, aroid-l!

From: Douglas Ewing <dewing at u.washington.edu> on 1999.07.17 at 13:35:53(3524) Eduardo, just a thought: when I re-read your description of this fungus, it sounds a bit like mealybug. I have to constantly be on guard against these insects, as they love the Amorph. tubers, particularly the emerging leaf or bloom. I hope I am not offending, but have you looked closely, even with a handlens, at that cottony substance? +More _________________/\/\/______________________ Doug Ewing, Greenhouse Manager (206) 543-0436 Department of Botany University of Washington Box 355325 Seattle, WA 98195-5325 On Wed, 14 Jul 1999, Eduardo Goncalves wrote: > Dear aroiders, > > I need EXTRA-urgent help!
