Transplanting seedlings with root rot....HELP

[Starbuck-Dubay]

Hello Orchid Friends!
back in 2007 bought 5 test tube orchids while vacationing in Costa Rica. This week, I noticed 3 of the 5 have fungus or mold. This has prompted me to remove the seedlings from their tubes and work on transplanting them. I feel that anyone with experience would tell me to forget about it and trash them, but I'm sort of on a mission to try and work this out. So far I've cleaned off the roots and set the seedlings on a paper towel to aerate and dry out the problem spores. This is just instinct but if anyone has any other advise to give me involving rot, mold, or fungus, please send it to me. I don't currently have funguside and I'm not sure which one I should get or if I should get one at all. For me, this is almost like a test beore I pull the other two from the womb for their transplant.
