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.

If they were in a sealed environment you still need to keep their humidity up high (90%+) so I wouldn't let them dry out. Since you don't have any fungicide you can dunk them in some hydrogen peroxide for a few minutes doing 10-15 sec dunks followed by rinsing them off with water. Before you start the H2O2 dunks soak the plant in some sugar water for 5-10min. The sugar helps the spores 'germinate' so they can be killed by the peroxide. Good luck with the babies! What type are they anyway?

Starbuck, Test Tubes from Orchids of Costa Rica? I also received a six pack last week but a couple have like white fuss/mold growing on the roots. The seedlings are less than 2 inches tall, including roots. Is it safe to take them out of the flask at this stage? I also have one that has all brown leaves but the roots are still green.
Some advice will be highly apreciated.

Soonix you can take the babies out at any time but you really have to baby them if they are weak. After they come out of their sealed environment they have to stay in a 100% humidity environment and be slowly adjusted to the outside environment they will be living in. This can take a month or more. Put them in a semi sealed container and slowly open the lid more and more each day (we're talking millimeters a day or less). DO NOT put the container in sunlight, it will superheat the space inside and kill them. Put them under artificial lighting. If they have mold they will die in the container they are in and the one that lost it's leaves is browning out in the tube and more than likely will not make it although there is a small chance it will.

Starbuck, Listen to Orchidoholic. They need high humidity for a while. Physan 20 is good if you can get it, but any product (fert, fungicide, etc.) should be mixed in a dilute form to avoid hurting the little baby plants.

Soonix, Sometimes, there can be some leaf drop in vitro that doesn't hurt too much. If there is only a root system left, and no 'shoot' I fear it may be lost. Don't give up on it though, it may surprise you.

Also, sometimes, abnormal proliferation of roots, shoots, or protocorms can occur in flasks, especially with certain species and/or media. Sometimes root proliferation can look "white and fuzzy." Just my .

I just had a bit of a fungus issue with one of my baby batches. What fungicide do you guys recommend spraying them with to prevent further occurrences? What's the safest?
