All of my Japanese maple seedlings dying

I planted 100s Japanese maple couple of months ago, recently I noticed they don't produce no more green leafs or they star getting yellow and dying in a sickly Way some sort of white powder covering the leaves. unknowingly I planted them in a really bad soil whit very low drainage and they started poorly anyway. Is the root rot causing them to get fungi later? Can repotting with good soil and anti fungi like mancozeb can save some of them? Is this even a fungi infection?
Thanks

Without more detailed information, it is all speculation.
- Where are you located geographically?
- Are these planted in the ground or in containers?
- What sort of soil?
- What sort of watering routine?
- Any photos that illustrate your concerns?

thanks for your reply. for some reason I can't upload any images. but the questions you asked pointed me toward a fix. I'm located in Sydney NSW, we had wet and not so warm summer this year. the plants were planted in small containers in seed raising soil with not many drain holes! since then after removing some of them for inspection I realized there weren't any roots and the soil was soggy and wet all the time!!! lots of root rot and smell bad! I removed all the soil and mixed them with %60 woody and chunkey orchid mix for better aeration and drilled lots of holes on the containers (i used empty Coca-Cola can for the containers) since then they revived despite 4 weeks of constant rain and cold temperature. some of them were reduced to 1 thin trunk and since then they produced some buds and leaves!!! I think the root rot cause them to become very weak and then attacked by fungi and probably bugs... I try to upload some photos later. thanks again

Well, you're going to have to do something about it anyway...might as well put it in a container now. Spring is the best time to do it anyway. Are you sure it's Hemlock? Yew can look similar when really young and it's far more common to see seedlings in landscaped areas.

Is my Japanese red select maple dying?

I'd suspect you are simply looking at transplant shock. June is not a great time of year to plant a JM in the midwest and some negative reaction from the tree is to be expected. Just keep it properly (but not overly) watered and it should produce some replacement foliage. If you could contrive some sort of midafternoon shade until the tree becomes established, that would probably help a lot. Red Select is quite sun tolerant once established.

Congratulations on your success!...a lot easier than faffing about with bags in fridges.Those leaves are actually not proper leaves,they're called cotyledons and precede the normal leaves.I wouldn't transplant them until you've got a couple of pairs of real leaves,no hurry,they'll follow soon.Just a good draining medium will be required as usual and is best,though I admit I've used normal potting compost before and got away with it. Just noticed the seedling,doesn't look like a JM to me,that one may just be a weed.

I think my Japanese Maple is dying.

It has heartwood rot so unfortunately is not salvageable. However, that does not mean the tree is going to die tomorrow. Trees with heartwood rot, while a fatal affliction, can live for many years with just an occasional branch die off. It does tend to make the tree less structurally sound and they can become overly prone to breakage or wind damage. The flat brown exterior fungus, known as a conk or shelf or bracket fungus, is a classic indicator of heartwood rot. With a tree that appears to have multiple trunks or very low branching, it is hard to determine just from the photos what else you need to do to preserve the tree for as long as possible. Or if it is so far gone it should be removed promptly. Bringing in a certified arborist for at least a hazard consultation at this point would be helpful.
