Their fine thin roots are easily damaged so bacterial and fungal rot sets in quickly. NY do you use an anti fungal systemic or otherwise when you repot? I have started a regimen of once every couple months watering with a systemic antifungal in the water I use along with my usual fertilizer and rooting hormone. seems to cut down on root problems. Remember that almost all my orchids come damaged to some degree with fungal and bacterial problems. they're all rescues.

Well, I doubt one whole plant will rot in a day, rather the problem must have been present beforehand. I have left plant in water overnight and no problem.
No, I do not use any chemicals unless I really have to.
Unless you have thousands of plants packed in like a big greenhouse, preventive spraying is not a good idea.
It might as well kill us before it kills anything else.
Now, when my plants get sick, I usually cut off the affected part and that is the end of it usually.
More serious cases, which I have not had many of, unless the plant is super rare or otherwise valuable, which most cases they are not, I just toss and stop worrying.
When repotting, I do not apply anything. I try my best not to hurt any healthy roots. then I water a couple of days later. Some people like to water right away, some wait. I'm the latter type. I have not had any problems because of repotting.
I think when you have plants that are already affected by certain disease, it is quite difficult to get rid of, of course, depending on what it is.
By talking to growers, I was told they just spray all the time because they cannot check on their stuff. simply way too many plants to individually check.
Ones that are sick, may or may not come back to full health, and even then it can take months!
Plus, when you bring in affected plants, remember whatever they have, will release spores and whatever in the growing area making it worse for other healthier plants in the same room.
So, it is best to start with clean and healthy possible plants. and provide good culture to keep the plants healthy. then you usually do not see many problems at all. Remember plants are usually always fighting invading organisms and most of the time, they can fend off themselves.
When disease organisms take over, it means plants basically lost.
