Gigi, shortly after arriving in Florida after my years on a sailboat,. I had purchased a mess of plants from a grower in Homestead Fl and a few of them were NOID. The staff at the nursery were super nice and told me the owner was an AOS judge and would be happy to identify them once they bloomed. When one of them bloomed I sent him the photo and got no answer. So I called and he gave me a different email address. That email was also ignored. I had recently joined a Facebook group called FOG (Florida Orchid Growers) and posted the photo there and within seconds there was a barrage of comments identifying it as virused.
I asked a bunch of questions and found out that there's many viruses that affect orchids but only 2 kinds of common viruses that can be tested for. It's transmitted by unclean clippers and unsanitary pots, basically any way that plant juices can get between plants. There is no cure. The only way to know for sure is to test.
Recently the experts have decided that thrips, scale and mites that pierce the orchid leaves or flowers then move to another plant can transmit the virus.
So while many people are ok with relocating a virused plant to the back 40…I am not ( because I show my plants at AOS judging)
