amorphophallus SICK Looking bulb HELP

From: "Greg Dorst" <gregg1- at charter.net> on 2004.11.15 at 14:11:11(12380) If it is injured or sick it finds its way to my house. Paeoniifolius Bulb, received from my friend, appears to have an injury from possible digging instrument used for its removal. It has been out of the soil for about 4 weeks. The gash is about 7" long and 4" wide. Ya it is a nice size one for sure. I have used a spoon yesterday 11-14-04 and removed the "Mush" and "decay", and some seemingly discolored tissue up to the point of clean healthy flesh. I would like to save this bulb if possible. There is a few spots remaining which appear as slight discoloration ( dark spots ) but still, "semi firm" that would require deeper and more radical tissue insult to remove. I would say that I extracted a good 15% of the bulbs mass. Is there anything else which I should do other than say a prayer? Is the extraction of the decay the proper means to save the bulb? Is there a wonder application to end future decay? The soil the plant was in, is it considered contaminated? My suggestion to that was, " dump it and avoid the risk of any possible contamination ". +More Thank you Gregg and Maggie Dorst gregg1-@charter.net _______________________________________________ Aroid-l mailing list Aroid-l@gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l

From: "Michael Marcotrigiano" <mmarcotr at email.smith.edu> on 2004.11.15 at 14:38:07(12381) If you know someone with a greenhouse that has a supply of fungicides you may want to apply Banrot (trade name) to the cut. It can be used as a powder and is often used for tuberous begonia etc and other easy to rot storage organs. Don't ask me where to get it but I have seen it used at a few places. +More _______________________________ Michael Marcotrigiano, Ph.D Director of the Botanic Garden and Professor of Biological Sciences Smith College Lyman Conservatory, 15 College Lane Northampton, MA 01063 email: mmarcotr@smith.edu voice: 413-585-2741; fax: 413-585-2744 www.smith.edu/garden www.science.smith.edu/~mmarcotr ----------------------------------------------------------------------------------- "Art is the unceasing effort to compete with the beauty of flowers and never succeeding."

From: Ron Kaufmann <kaufmann at sandiego.edu> on 2004.11.15 at 14:54:15(12382) Dusting the wound with powdered sulfur can be very effective in stopping the rot. Since most people (myself included) don't have powdered sulfur just lying around the house, a very good alternative can be powdered cinnamon. I've had very good luck saving tubers by doing exactly what you did, coating the exposed area with powdered cinnamon, and allowing the cinnamon to dry. Good luck!

From: "D. Scott Taylor" <staylor at brevardparks.com> on 2004.11.16 at 14:35:37(12384) I have posted previously a couple of times about similar problems I have had with paeoniifolius, and based on those communications I have surmised that it can be a 'problem' species. Now I am wondering/hoping that some clones are maybe less subject to this disorder. I have had ongoing problems with 'rot' in this species, particularly with larger tubers. I have tried cutting away the rot area and treating with fungicides (I have tried Captan and Mancozeb). I have also tried sulfur and treating lesions with bleach: sometimes this works and sometimes not: often the rot will continue until much of the tuber is consumed. Oddly enough, when I get rot on konjac, the simple cutting away of the lesion seems to solve the problem, so these two species seem different in this regard. The recommendation I have had is that damaged tubers not be replanted, and also do not reuse planting media. A well-drained media is also supposed to be very important. I have tried drenching the soil with Mancozeb throughout the growing season, and this really didn't seem to help; my suspicion at this point is the the problem may not be fungal in origin: in fact, I have sent two different samples to path labs with no definitive results. This remains somewhat of a (frustrating!) mystery!!! D. Scott Taylor +More On Nov 15, 2004, at 9:11 AM, Greg Dorst wrote: If it is injured or sick it finds its way to my house.
