Rings on phal leaf

I'm no expert but this looks like it could be a virus to me. Should I bother getting a test kit or just pitch it? Or does it look like something else? Thanks
Jenny

I agree. Rings are not usually considered to be an encouraging sign. Sometimes it can be a fungus but usually it means that you should have your orchid tested for a virus.

Do all virused plants show color break in the flowers?

No, not all virused plants will show issues in the flowrs. Some virused plants will never show any issues at all.

That particular phal would worry me. Immensely. I would probably just pitch it because that's what I usually do. However, if it had sentimental value or is an expensive plant or one that's hard to find then I would test it.

Thanks. I will def pitch it. I've only had it a few months so no sentiment I just like the flowers. How concerned do I need to be about the plants that were around it? Water splashing and such?

Touching leaves won't transfer virus...as long as there is no open plant tissues.

Splashing water would only transfer virus if there is open tissue involved. For instance, a cut leaf to cut leaf or you cut roots on the "infected" plant and then cut the roots or leaves on the next plant w/out sterilizing the tool. Even then...as in humans and our viruses...it's not a guarantee of infection...some plants can fight things off better than others.

I once read an article that stated most collections have something like a 45%-65% virus infection rate...and most of the the plants never show any problems. I don't know how accurate that article was but I've always just gone w/the thought that I surely have virus in my collection somewhere and I practice good hygiene. I'm not perfect with it all but I do my best and I don't go all crazy over it. If something looks suspicious, I pitch. If I ever have one of my harder to find orchids, one of the larger ones, or one of my favorites ever suddenly looks suspicious then I will test.

In the end, I'm not "breeding" plants or starting a plant business so I'm not going to lose sleep over virus or the loss of a plant. IMO, there are far bigger things to get upset over and far scarier things to worry about.

Thanks kat. That makes sense. I have heard similar stats about infection rates in private collections. I won't worry too much and just toss anything that looks suspicious. Thanks for your advice. I really appreciate it

Color breaks can be a sign of ORSV infection, note the "can".

For the rings, yes, cercospora (fungus) can be very similar, the only way to be sure is to test. Meanwhile: separate it from others, it's under suspicion (save if you decide the bin is the thing to do).
