I response to message 4 what type of antiviral treatment did you use. Years ago there was some work done on using heat to kill the virus. There must be some published work on this. As far as a chemical treatment I have not heard of any chemical that will kill the virus. Some antifungals will reduce some of the viral symptoms but do not cure anything. I have done a lot of propagation work with orchids which can get several non orchid viruses (TMV for one) and several european growers were trying hot water treatments to kill the viruse. There was some success but it was found using meristem tissue (fast growing new growth) did not have high amounts of virus in the tissue. By removing this tiny growing point and culturing on sterile medium you can produce virus free plants. I'm sure they are using a related procedure to mass produce Hippeastrum. My advice would be to isolate any infected plants and unless they are the last specimen in the world burn the whole plant. Most plant viruses are transmitted by insects through their sap. If you handle infected bulbs wear latex gloves or some other barrier. Remember the virus is all through the plant,leaves,roots and bulb as well as flowers.Most badly infected plants produce deformed flowers. The flower can be deformed or have color streaking/blotching/spotting.Oh throw away that dirt you had your infected plants in cause there could be some viruses lurking there that can spread to your healthy plants. Also some plant viruses can stand drying and still be infective. For those not familiar with plant viruses just do a search online and you will be stunned just how many types there are. So do yourself a favor and get rid of the virused plants. When cutting flower stems always use a sharp instrument,like a razorblade dipped in rubbing alcohol. The alcohol will kill the virus and the blade is reusable. Remember to keep infected plants separated from healthy ones. Russ H, BS, MS in Botany In a message dated 6/18/2013 9:02:57 A.M.

We have some LA iris in bloom both hybrids and the very late species I brevicaulis. Also a few I. psuedata. This name may be new to some of you. It is a hybrid of I pseudacorus x I ensata. Modern hybrids are far superior to older attempts and have large flowers in a range of colors and patterns. And they are sterile so unlike the pseudacorus parent do not seed about wildly. Recommended for pond or well watered garden spot. Check out Draycott Gardens for some pix http://www.draycott-gardens.com/psframe.html I don't think there are any pix on the PBS wiki yet.

I think the method is OK as a last resort. It certainly eliminated the of mosaic virus marking on the survivors, but I can't be certain it is really gone. The bulbs I treated were identified as H. equestre red, H equestre pink and two different H reticulatum striatafolium, all from Thailand. The 'equestre did the best with substantial leaf growth and decent root growth. The reticulatum bulbs keep aborting their leaves but had good root growth. I decided to dispose of the virused bulbs to protect all my others. -- Dr. Ellen Chernoff, Ph.D. Associate Professor of Biology IUPUI-Biology SL 360 723 W.

Buds are out but mostly green on other lilies. Late Pacific Coast iris are flowering; these are I. tenax selections and some hybrids (tenax x innominata), and dwarf I. douglasiana seedlings. Also one clump of I. hartwegii australis continues to toss out a flower every week or so. Colchicum foliage is dying down, so I am digging out bulbs to make room for more iris plants. Lobelia tupa has flower shoots with colored buds, though I don't expect flowers for some weeks to come. Ornithogalums are flowering, as is Sisyrinchium californicum, S. idahoense, and several selections with blue flowers. Seeds are ripening on several Erythroniums??and I may be able to send seeds to the exchange in several weeks.
