class="iAs" target="_blank">Hippeastrum forum lately and there is
a big scare going around with Tobacco Mosaic Virus. I actually found
two in my collection that have it. My question is are there any aroids
that are susceptible to this virus? I am especially worried about
amorphophallus species. I would burn every hippeastrum I have to
protect my amorphs. Thanks for any input."

I've never heard of this virus, can some of you guys and gals fill
us in on the details and potential dangers?

In regard to susceptible species, here is a quote from the University of Minnesota Extension:

http://www.extension.umn.edu/distribution/horticulture/DG1168.html

In Minnesota, common plant hosts for the mosaic virus are tomato, pepper, petunia, snapdragon, delphinium, and marigold. Tobacco mosaic virus also has been reported to a lesser extent in muskmelon, cucumber, squash, spinach, celosia, impatiens, ground cherry, phlox, zinnia, certain types of ivy, plantain, night shade, and jimson weed. Although tobacco mosaic virus may infect many other types of plants, it generally is restricted to plants that are grown in seedbeds and transplanted or plants that are handled frequently.

Tobacco Mosaic Virus (TMV) and Cymbidium Mosaic Virus (CyMV) are big problems for orchid growers.

I have even seen symptoms show up in lilies potted in used orchid pots.

There are home test kits called "ImmunoStrips" available through a company called Agdia.

The virus can be detected, but not cured.

Thanks to everyone for the info. I've never seen the problem but was
just curious about it.
