Bulb is turning soft,and you can see the one that rotted and fell off.What
fungicide works best here? A lot of reading indicates etridiazole, which I
have not tracked back to a brand name yet.

Bruce, I'm not usually one to give up easily, but that looks like a goner.
Which treatment at this point depends on what you can get very quickly. This
group recommended Cleary's 3336 to me when I spotted a large scale (not the
bugs!) problem. It's great stuff. For follow up, Physan or Phyton work very
well.

From what I can see, both the outside pbulbs are shot. Cut them away. I
think I see rot on the base of the middle one, too, but if I'm wrong, treat
that lone pbulb by soaking it in a fungicide/bacteriacide. Then do the spag
and bag trick and hope for some new growth.

I know that flower; I have that plant. It's gorgeous. Still, sometimes we
lose a few.

I read Diana's reply, I looked at your picture.
I agree that it is a goner. So much so that I wouldn't try any remedy at
all. It looks to me that the base of each pseudobulb is dead and the new
growth that started has died also. There is nothing left that can grow on.
This type of problem starts in the rhizome. It can spread the entire
length of the rhizome, dooming the plant, before it starts to travel up
the base of the pseudobulbs where it can be seen. I have a plant do this
once in a while. I discovered two plants heading down this path in the
last 3 months. Both had several growths (unlike your plant with only 3)
and I was able to find a section where the rot had not spread yet. One
looks like it will make it for sure. The other one I can't tell yet.
The rhizome of your plant seems to be covered by the medium. I plant
mine a little deep sometimes too because my humidity runs kind of low
and I've had roots dry up before they reach the medium. I do believe
planting deep makes this disease much more likely. Even more so if your
humidity is also high keeping the top layers moist longer.
Didn't mean to write a book.

Write away!!!! These small novels teach me more than the over the shelf
books.
I haven't pulled it from the pot to see what other growth may or may not be
there. I suspected it was a goner. I have another Chyong Guu Chaffinch that
is healthy (I split them a year ago) so I am not too attached to this one.

I run about 40-52% humidity in the house, although that spot is probably
lower since it is next to the window and air from a A/C and heating vent
hits that wall and runs over the flowers.

How deep would these normally be potted? I went by the pictures in a couple
of books I have.

This is going to be a long weekend fighting scale and rot!

Bruce,

potting depth, you don't want to completely bury the rhizome. Also, the
area on a pseudobulb where an eye either is or may form should not be
buried, or the eye will most likely rot. Basically, the base of the
pseudobulbs should be kind of sitting on top of the medium. If the plant is
wobbly when repotted, just use a pot clip, avoiding the edges of the bulbs.
