Does this product contain any Fungicide or preventative treatment?

Not that I was aware of. And nor does any other hardener I've personally come across. Any hardener would presumably help resist fungi & beetles etc, but before using this I apply such other treatments separately, then put this stuff on the following day.

Can it be applied to wet wood?

The instructions on the tin say the wood should be "reasonably dry", so it's best to remove as much of the wet rot as possible and leave the remainder to dry for a while. It worked well that way. My only problem was that the supplier was unable to send this product outside mainland UK, presumably because of postal restrictions on the chemicals in it, and, being in Northern Ireland I ended up buying it from Screwfix.

Work on wood that will be put in soil at allotment, toxic to the soil? i have a spare bottle handy and putting some posts in.

Nor sure it will prevent new rot in fresh pressure-treated wood very well - it is very good at hardening existing rot. Probably not very good for the soil either, but possibly better than the creosote we used to use. Hammer-in or cemented base anchors probably a better long-term solution.

Why is this so seriously overpriced

Its definitely expensive . But great treatment for wood
