I am not certain, but my first reaction would be that it is a virus.

I am afraid that Phal has its destiny with Dr Bin....

Difficult to do anything about a virus attack like that.

Definaly looks like virus, best way to cure it is to place in an over at 200C for 30 minutes
In other words destoy it as it will soon spread it all your nearby orchids.
Sorry

alan-rr, sorry to say, but my first guess would also be that it is a virus. Some fungus infections can have a ring-like appearance, but I think a virus is more likely. Only way to know for sure is to have a plant tested (for example, through Critter Creek Labs).

Unless it is a prized, named, champion orchid, it is not worth the effort.

It would probably cost more than a replacement plant.

I've always wondered about the cost of virus tests in other countries. Anton what does it cost to have a plants tested down under?

The do it yourself tests that only test for the two most common virus are $5 and very reliable. If you send sample to a lab, it also averages about $5 per plant but the more samples you send the cheaper it gets. You can also request additional virus tests and the price for the additional tests is about the same.

Same as Catt Mandu, virus or some fungal disease.

If it started on an old leaf, it can be an indication for virus.

You can:
- trash it on sight
- isolate it, treat for fungus by 2 means simultaneously (watch out for no insect around), and if it stops, it may be fungal.
- test it (a few $ the test) if it's worthwhile then decide.

(Personally, I wouldn't test the limits and would trash or test -I have test bands)

Keep us updated if you decide not to trash, but be very careful not to spread the thingy.

May I keep the pic for reference and show? I'll be giving pest and diseases conferences soon. You'll be credited of course.

Phal problem

Thanks for all the replies to my Phal problem. It is ringspot, I bagged it in a plastic grocery bag and put it in the trash (and the pot and mix).

Its a hell of a lot more expensive here in Oz, not sure of the exact cost but will find out and let you know.

Hi Anton, good to hear of the todays cost at labs, a few years ago a member of our club member had some plants that members told to them were suspect virused and they send to a lab, AU$15 each and they were report came back as virused..My personal opionon is is if they look out of the ordinary or have funny patterns on the leafs or on the flowers I do not want them in my collection looking like that so into the bin.

I would not bother testing or spending money on testing, as I said if it looks funny into the bin, would you like to have all your Phallies leaves looking like the above one, well not me, bin it or better still burn it so no one will get a piece of it.
Just they way I love to keep my collection nice and clean!

Ron not all virused plants look like the leaf above. Many times the plant is symptom free but still has the plague.

And some mosaic manifestations can look just like some fungus, and one fungus can look a lot like ringspots. You can be suspicious, very suspicious, especially if it's the old leaves or if the plant is not thriving as it should. Maybe the only symptom that can be considered stamped "VIRUS" is recurring color breaks. If you have repeated color braks over 2 flowerings, I wouldn't bother: suspicious at the first occurrence and isolate, trash at the second.

In France, test bands are about 7-8€ apiece.
