NOT ONE. So that

I must take exception here and quote the following from the Agdia Inc web
site. http://www.agdia.com/cgi_bin/catalog.cgi/44501
Agdia is the manufacturer of easy-to-use test kits, reagents and laboratory
testing services for the detection of more than 150 plant pathogens
(viruses, fungi, bacteria) in vegetable, orchard, ornamental and field
crops.
"Cucumber Mosaic Virus (CMV) naturally affects well over 400 species of
plants. While the most common symptom of CMV is mosaic, a number of other
symptoms can result from CMV infection, depending upon the type of plant
affected. Some of these symptoms are flecking, dwarfing, and fern leaf.
Cucumber Mosaic Virus is primarily transmitted by aphids. However, this
virus can also be spread through the seeds or bulbs of some species."
In addition the Research School of Biological Sciences of the Australian
National University http://life.anu.edu.au/viruses/ICTVdB/10040001.htm
states:
"Transmitted by a vector. Virus transmitted by mechanical inoculation;
transmitted by seed (in 19 species, but in variable extents). Transmitted by
an insect; more than 60 ssp. including Acyrthosiphon pisum, Aphis craccivora
and Myzus persicae; Aphididae. Transmitted in a non-persistent manner.
From the Department of Plant Pathology,CTAHR, University of Hawaii at Manoa

"EPIDEMIOLOGY
CMV is transmitted primarily by aphids, and also by seed, cucumber beetles,
parasitic plants, humans, and mechanically"
All due respect but clearly these Experts disagree with you that "There has
NOT been ONE RECORDED CASE of CMV being transmitted via seed".
Because of the expert comments above I suggest that you are probably
incorrect in your recall that Dr. Eddleman stated seeds were not a potential
CMV carrier.
> The key is ISOLATION.
The consensus is Not isolation but rather that varietal resistance is the
primary management tool. Of course eliminating weeds and infected perennial
ornamentals that may harbor the virus is critical.

A wasted effort as it takes but ONE tiny aphid to carry the virus in or out
of your protected environment.As siad above "varietal resistance is the
primary management tool", largely because you can't tent the world.

Please attempt to express your "opinions" without name calling. Most
people, yourself included I am sure, take offense when they are called
"simple-minded". Something about glass houses also comes to mind.
