Fungi to fight crown rot in plants (rhubarb specifically)

Has anyone had experience using fungi to treat diseases like crown rot for plants? The one I'm thinking about is using rhubarb to treat crown rot, since it's still spring (frozen ground), and I was walking on water logged soil while fruiting started that's the same level as the rhubarb patch I put in last year. Last year it was very dry, and the creek dried out (think black mud).

I haven't got any experience to share, but thought I'd 'bump' this thread for you.
So I couldn't find any links to fungi treatment preventing crown rot, mostly the advice seems to be to dry out the soil a bit by raising the plant up. Are you talking using Rhubarb as a fungicide? that would be news to me too. It sounds more like you are worried about your Rhubarb getting crown rot because of the damp ground. Hopefully someone might have an idea for you.

No I'm asking what mushrooms eat root rot.
