Ray, I swear nothing has changed, not even the slightest thing. We did have
some cool nights, and the humidity was high. So, there you go. Believe it or
not, this has moved so fast that between the time I wrote the original post
until now, I can see more damage. It's clearer now than it was then. This is
not insects, though when we hit it with the soap and oil combo that's what
it looked like. It's either fungal or bacterial, most likely the latter. The
black spots are indeed the secondary problem, though. The major issue is the
yellowing from the outside of the leaves.

I have work to do in the morning, boys and girls. I have Physan on hand, so
that's what I'll use. And we'll do wound control to the best of our ability.

Sorry you had to agree with Gene again, Ray! G Don't sell me any plants
until I get this resolved.

Diana

Damn! Two days in a row I have to agree with Gene.

The dark wounds on the leaves are the lesser indicators, in my mind, and
the problem solver makes me want to ask what - no matter how seemingly
insignificant - has changed?

Diana,

Since it's sudden and hitting multiple plants I would guess this is
something in the culture. The black spots look to me a bacterial
infection.
The sudden yellow leaves would make me suspect something chemical.

Has there been any over spray from near by? Did someone spray the
azaleas
and the wind pick up the spray and it got on the orchids?

I think I remember you are in Florida? Was there a real quick change in
temps that could have caused a bacteria to florish? Some of the
pictures
look to me like the plant got chilled and as a result the leaves are just
not turgid.

I had a Phal schilleriana "Pink Butterfly" that was hanging and growing
like
a weed. A month ago I walked into the greenhouse and the newest leaf was
on
the ground. The crown rotted in a matter of days. I know water wasn't
collecting in the crown because the plant was mounted so everything
drains
out. The crown was all mushy.

I wish I could be of more help to you.

Gene

I just posted the following to rgo. It is *not* cross posted. I hope
someone
can ID this mess. Will post the pictures in succession in this thread.

Well, we have a little problem here. Walked out on the patio on Friday
morning and saw severe damage to a number of Phals. Mind you, seeing
them
every day is unavoidable, so I can assure you that these probs were not
evident the day before. Clearly, something had been in the works, but I
hadn't noticed.

The leaves are turning yellow starting at the outer edges. The under
sides
of the leaves look moldy and pitted. Some of them have what look like
sunken
areas on the top of the leaves, but those are not soft. There is no sign
of
snails/slugs, and those things would be unlikely to find them where they
live. There is no big web infestation, so I don't think it's spider
mites.
My guess is some kind of mites, however. Saturday we sprayed everything
(*everything*!) with soap and oil with some alcohol thrown in for good
measure - 6 tb/gallon.

Pictures going up in abpo in 1 minute. I'm really worried. Here I teach
a
class for newbies, and look what I've got.
