browny black hair growing on some leaves

[arklan]

ok been googling this for about an hour and couldn't find any information
some of my plants have some little hairs growing on the lower leaves in my diy greenhouse
I already put in a bunch more holes in to the glad wrap for better airflow but I have no idea what this is or how to treat it
any advice?

hmmm. Do the those trees happen to be Port Jackson Figs? Jokes.

Some here are incredible in their IDing of diseases. But a photo of the problem would really help.

Gladwrap????? It's probably humidity induced mould that's come up from the soil. I would not have throught that gladwrap would be such a good idea.

They could be lace wing eggs.
Lace wings aren't bad, they are predators of other bugs.

I'd say your plants have had too much time to themselves.... you know what they say about the palms.

Seriously though.... wtf? picture mate!

How good is your eyesight? Could they be pests of some kind..... sounds odd.

sorry for lack of pic, i just saw it on my way to work and didnt get home until dark
is there any chance that this plant might live?

edit: its a narrow leaf paperbark

That is definitely a fungal infection. High humidity and lack of fresh air promotes infections like this. I think this one is a gonner. Spray everything with a fungicide as soon as possible and get them all into fresh air and sunshine and you might save some if they are not so badly infected yet.

Most of our seedlings do not need to be kept wrapped up. They will often grow just as well in the open air and there is definitely less chance of infections like this. Also fill up containers with mix when planting seeds or seedlings. The dead air when planted low in a pot will help fungal infections as well.
