What's the etiquette rule?

David, how accurate are those tests? Is there a way to know? I'm just wondering if it's possible to get a false positive or anything like that. It'd be horrible to be throwing away plants that are not actually virused. Of course, even worse is for a bad plant to infect all the others (how do virii spread on orchids, through chewing insects or being near an infected one, or is that known?). At any rate, sorry about the issues, that's terrible.
