Just did some checking and it is NOT the same stuff. I suspect it might have the same effect, but who knows? The page I found says isopropyl can be found here, but tends to be difficult to get hold of, expensive and might only be in swabs!

Got to go out now. Seedling looks much the same so, as before, I think it's probably stopped or it's already too late.

remove from the current moss to spray hydrogen peroxide on the whole plant then repot with fresh moss.

the first sign was the discoloration of the root meaning an infestation(either caused by algae or fungi ; its not bacteria= is fast and can kill the plant in a couple of days), then the mechanical bending of the new leaf due to a fall made them enter the cells of the new bud and had a feast....yet your plant is a hardy survivor.
cut the damaged part of the new leaf and repeat peroxide every day and then when the root is back to its normal color repot in fresh moss again....that plant can go bare root for a month as long as you peroxide it every morning....when the extra oxygen evaporates from peroxide=you only have water left so its like watering the plant every morning and doing away with the infestation

No, surgical spirits is not the same; it's usually ethyl alcohol with some other things added (like methyl salicylate, which is what usually accounts for the slightly odd smell).
Isopropyl is propanol (rather than ethanol).
I often use surgical spirits for point treating scale with those ear bud things.

Removing the dead leaf isn't an option: I'd damage healthy tissue doing it. I'm also not going to put anything down there that turns into water since it seems likely that it getting too wet in there is a factor. I think on that I'm going to have to stick to hoping it's stopped on it's own.

Not sure about treating the root: as I said, it's had it for months. It's also on the exposed bit of the root rather than the bits that are covered. If it's an infection it's secondary to that bit of the root drying out too much, which is probably the opposite problem to the leaf!

Just wanted to say thanks for all the sugestions, even if I'm too stuborn to follow most of them *G*

I'm thinking I might try the peroxide on the root if it does survive: I've had experienced growers I know in real life tell me that kind of thing is nothing to worry about, but even so it would be nice to clean it up! Especially if it is a potential source of more serious infection. Don't want to fuss the plant more than I have to at the moment though.

Angraecums are tough so you will likely be fine, either way. I might love the leaves and flowers but, what makes me a devoted fan of the angraecums is the ease of growing them. I am quite certain yours will recover without much fuss now that culture is corrected. :)

How is ur plant doing now? I agree with u that putting something in the crown that turns to water is risky! (:blushing: I had forgotten that peroxide turns to water (& oxygen) so thank u Leafmite! (I won't forget that again) I'm glad that u didn't listen to me Rowan! :blushing: I'm so sorry about that!) ...u should always listen to ur gut

Hi, it's still with me. It turns out folks were right about the root: it has now died off. It's just started a new root, so hopefully that will develop. I think I probably am going to do some cleaning with peroxide: I haven't had time as the last few days have been manic.

Fresh peroxide is actually great. It is just that you need to be certain it is fresh. I like alcohol as it displaces water, then quickly evaporates.
How is your elephantinum? I just moved mine off the mount into red lava rock/net pot as the roots needed more humidity around them.

Great to hear it is going to survive. :)
