I just had the same experience today. I got back the results and 4 of the 13 I sent were positive for CymMV. So far I have not had any ORV. I'm debating on what to do with the plants that were in proximity. Only one was on a table near other plants, and I have had that one for awhile so who knows how long it has been infected. I'm very careful to sterilize pots and bleach/flame my pruning instruments before and after use. Any thoughts on anything else I should be doing?
