What Fungicide is safe for seedlings?

[beachbum]

Is Daconil safe for seedlings or is there another fungicide that is considered safer?

[BeyondTheGarden]

I normally use regular hydrogen peroxide in a spray bottle.  It seems to work surprisingly well.  I've hit probably over a hundred seedlings with it.  I only thought I ever damaged one seedling (A Jubaea) but I'm not sure that H2O2 was the cause of the damage, as Jubaea seedlings seem to enjoy dying for any and every reason. 

I'm not super smart on anything, but I know that the way that H2O2 works is pretty unique, it's a powerful oxidizer (on a very small scale) and kills very small living things by chemically burning through its cell walls.  Then it chills out and turns into regular water.

I use chlorothalonil for seed storage, baggy germination and on seedlings. Just dont put it on a plant that is flowering and wash your hands after use.

It really depends on what you are growing. When I was germinating rare palms and cycads I used Subdue and Banrot with good results.

Physan20 is one I have used for many years.

You have used brand names. Telling rather active substance, is way more helpful to growers in other countries, where products even from same company are available under a different name.

Yes, of course you are correct, sorry.     

The package shows n-alkyl dimethyl benzyl ammonium chloride  10%, n-alkyl ethylbenzyl ammonium chloride 10 %,  and inert ingredients 80%.

The OP's location is South Carolina so he would have access to the brand names I mentioned. I learned about these brands right here on this forum several years ago when I was living in Mexico city and at the time, did a Google search of active ingredients. If mentioning brand names is against the forum rules them my bad, otherwise I was only trying to help.

My rare seed or expensive seed i spray with daconil literally one spray also use it on seedlings and I think it works . And I don’t see it effecting germination or any problems on seedlings . So I swear by daconil . But a little bit goes a long way .

Do a Google search with "brand name active ingredient" and probably the first result will tell you.

I also want to give you this link, it is very well done and is worth using the Google translator https://info.agrimag.it/principi-attivi. 

I use propamocarb, it is specificaly indicated for the fungi afflicting young plantlets, Pythium, Phytophthora, ...

Thanks for all who took time to reply.

Pythium and Phytophthora are usually guilty for preemergence damping-off.  For postemergent deaths of seedlings is usually guilty Rhizoctonia. (all of those fungi, included Thielaviopsis and Fusarium can kill though also juvenile palms established in the ground).  Banrot looks more suitable, as it treats all kinds of soil fungi and in a curative way too.  Has anyone tried a biological preventive treatment with Trichoderma asperellun or Trichoderma atroviride?

Can you find Banrot (etridiazole) in Greece? It is banned in Italy

I have never made a serach for this ingredient. On the other hand I can still find in the black market the other ingredient thiophanate-methyl under the brand name Neotopsin.
