Thanks mmursuli and Betty for the LIKEs.
Angel, Take a picture of the roots and post it.
Also...cut a root that is still alive and look to see if it has a purple ring in it. Let us know.
Angel, you need to spray with a systemic fungicide.
I don't believe this has anything to do with watering. For the roots to just collapse and die makes me suspect fusarium.
Angel, Yes it does move and by all the typical avenues such as water splashing on a neighboring plant. I'm going to IM you a site to take a look at some photos.
Here is some info:
Fusarium blocks the flow of moisture through the plant’s vascular system plugging the phloem. Infected leaves are yellow, thin, shriveled, wrinkled or wilted and eventually die.
The diagnostic symptom in the plant is a circle or band of purple or pinkish-purple discoloration on the outer layers of the rhizome evident when the rhizome is cut. If the disease is extensive, the entire rhizome may turn purple, and the discoloration may extend to the pseudobulbs. Severely infected plants may die in 3-9 weeks, while mildly infected plants gradually decline over a year or so."
Cathy, I think I know why some of my orchids have died the way they did. Read my PM. Anyway, I hope my suspicion's correct. None of the dead orchids exhibited any of the usual signs of fusarium.
