The good news is that you can spray and probably save your plant. Captan 50W, Liquid Copper, or Phyton 27 will treat both of these. Or if you want to treat separately, Daconil will treat the Erwinia and Mancozeb will treat Anthracnose.

The bad news is that you need to treat quickly. Erwinia can kill very fast. Anthracnose not so much...slower. Erwinia is way aggressive and most common especially in high humidity, high watering environments.

Thanks! I'll check it out. I've quarantined it already, but if it is then I am sad. Why me? Why? And of all the times, it chooses the busiest time of my semester!

Yes, if the leaves are dropping off and the infection starts from the stem, unfortunately, it isn't Iron deficiency.
I haven't used the other fungicides but if you use Captan, you need to spray it outside with protective gear and let it dry outside. It is what I use on my fruit trees. If your college has a greenhouse or does any research with plants, perhaps they would be willing to help you with treating your Amesiella.
Good luck!

Checking in! Been busy for the entire summer because we got a puppy, but my plant is still alive! I'm still growing it in the pot it was purchased in and so far, it seems to be doing fine. Lots of new root growth. I doubt I will see a spike this year, but I'll take the growth!

Default Amesiella monticola (project 16 [main] - spring 2015)

Did a close inspection of my monticola this morning and found that it is growing a new root and mmmmaybe something else? Too early to tell, it seems kinda big of a nubbin to be a spike, but only time will tell the clear new root is right in the middle of the two lowest leaves and the mystery nubbin is right about the lowest right leaf. Also, the new leaf is taking it's time to grow VERY slowly lol

It will be interesting to see if yours is developing a bud. I am just happy mine is continuing to grow.

Unhappy

I'm so disappointed. Most everyone has new growth, new roots, even a couple of spikes and I still have the same plant I got way back when. I have read all posts trying to see what I might have missed, but have not gleaned any answers
I have mine in a net pot with bark, water every 2 or 3 days, fertilize every other week, quantum (probiotic) every other week. It's under the t-5s about 18 inches away in a fish bowl with lava rock and water for humidity. The humidity in the room is 55 to 65%
I don't know what I'm missing. It looks healthy, roots are green, but nothing seems to be growing.

If everything else is fine, it's likely the humidity is too low.

I think the humidity is fine but I don't know why nothing is happening. Mine shows no signs of a future bloom but I notice a new root has started and it has gotten two leaves since I bought it. Mine does need a little more humidity. The older leaves look as if they are suffering in this drier weather.

It'll do something soon enough I am sure. Mine does not have a spike, I think you saw some sphagnum sticking up from the pot in my picture. But I do have a new leaf. Keep giving yours the good care you are giving and you will get growth soon. My stem seems to be swelling but it may just be from producing a leaf. I keep eyeballing it for a spike b/c it seems stems always swell when there is a spike coming (or sometimes leaf).

I found some more information that might be helpful. It seems that monticola may grow cooler than we might have expected.

Australian Orchid Council Inc. - Orchids Australia Magazine

The leaf loss and fungal issues may be brought on by heat stress. I'm going to see if moving mine to the cooler zone improves the growth habit.
