The viruses that Agdia ELISA screen for are but only a few of the viruses that are carried by plants.
However, they are lethal to the plant. Maybe not today, but eventually.
Furthermore, one plant that handles virus well could infect another plant which will die from it very quickly.
I have compared this before to the testing of human blood for viruses prior to transfusion.
HIV and Hepatitis C are screened because these diseases are uniformly lethal. Maybe not today.....
Just because we cannot screen for every possible blood bourne virus does not mean we forgo screening for HIV and Hep C as one person can easily live a long life with HIV, and another will not.
This is the same concept we are using for our plants.
Many will argue what is the point of testing a healthy plant...the point is the healthy virused plant can infect your healthy non-virused plants and kill them. Period.
As far as vendors handling this, it is a nightmare of epic proportions.
As a vendor, how can you justify spending over $5 to test a plant that might have cost you even less?
And how does one recoup that expense? Pass it on to the consumer who struggles to pay $5 at Home Depot for a NOID? They will shop elsewhere!
And across the Pacific where these plants are mass produced and imported by our vendors, virus is not even considered. The attitude there is that it is a minor consequence for the availability of volume and variety supplied to our massive consumer market.
How does your business survive?
I guess a bad economy wasn't enough stress on orchid businesses
I call vendors and quietly and honestly tell them about my testing and collection preferences. I have had some very notable people request that I don't buy their plants.
Others, work with me and have become friends.
Either way, I respect their struggles in a business with (usually) very small profit margins.
