fungus spreading?

[FinnBar]

Hi there. I got a phal as a present. the roots turned out to be rotted and the pot had fungus growing on it. I removed the plant and trimmed all dead roots, lots of them. it was left with just a couple. i treated it with cinnamon. if i put it in my tank to heal do i risk the fungus spreading into the Aerangis inside the tank, humidity is 90+?
no visible signs of fungus on the phal.

Yes you do. 90+ humidity is hard enough to deal with (I know 'cause mine runs up to 99% at times) with fungus. If it were mine, I would spray whole plant with Physan 20 and place in a plastic bag till new roots form. Be sure to keep plant and bag out of sun and real strong light. Keep kinda average light like a north or east window.

One word. . .quarantine. . .ur two more words. .that baby!

I think it would be nice to have an aquarium set up just for an intensive care unit. Set up with good light, humidity and a fan. . .but I am sure a bag would work well too.

I've only used the Physan 20 once, at Ross's advice, and it worked like a charm. So if you don't have any go ahead and buy a small bottle to keep in stock.

Thank You!

I haven't come across Physan 20 here in Finland but I'll
see if i can find something similar. could you give me the name of the active ingredient? I have the plant in a transparent plastic (ikea) box with a lid on an east-facing window. i'll install a fan today. sounds a little like the unit you were describing gmdiaz..?

Thanks, evidently i wasn't smart enough to google it myself.. fortunately the plant was quarantined as there's fungus growing on the remaining roots. should i just cut them all off? would neem oil be of any help?

[Ross]

Why not hunt up a garden fungicide locally? I'm not positive, but Captan, sulpher, etc. might work. I wouldn't cut off the roots just yet if you can get some fungicide onto them.

[FinnBar]

I gave the plant a treatment using Ray's alcohol-cinnamon recipe and added the fan. so far so good. the leaves look really wilted though. i'll send an update after i return in a week or so and start a search for the fungicides if necessary. I hope i don't come back to a case full of "cotton candy"..

i would wait awhile. it seems to me that orchids take forever to show you they are sick. i would isolate it for at least 3 months before i put it back. i have a problem right now and can't tell what started it or i would have had it outta there.

This fungus stuff is killing me. This spring I repotted and divided practically everything I have. I disposed of all old media and practically made all pots new again. I've been running into what I guess is black rot here and there on new growth. I bought some rather expensive BANROT to spray and even dunk my plants in it. Perhaps it takes a while but I'm still getting die off on new growth as it tunrs black. I have now covered my shade house to protect against the daily rain so that the orchids have a chance to dry out. I use cocohusk or aliflora as medium mixed with charcoal. Sometimes I mix the aliflora with the coconut. I know I just have to keep working this and hate to throw out a plant that has blackrot. I just cut off the affected part down to where it started to grow and hope for the best. Is this accepted policy or is the plant lost? The strange thing is other parts of such an orchid look good. Is the rot at the root level or only in the new growth. Here's a picture of one plant I just photographed. I then cut the bad stem off and have the pot standing on its own under roof. But others ar near other healthy plants. Can they hurt them even though I spray everything?
Note the black shoot on the right and a new good one on the left.
Just looking at the picture, I'm using bark here.
