Good fungi, bad fungi?

[philip_la]

I don't know if this has been addressed before, but has anyone ever used mycorrhizae in their seedling mix in an effort to stave off the bad fungi? I don't know if my understanding of such has any merit, but I have had seedlings push through fuzzy media in the past without any noticeable problems. I've been steam sterilizing recycled potting media lately, and I'm not sure but what this year's resultant fuzzies are more detrimental to this year's lot of seedlings.

(Not that I'm complaining too much -- I need some early culling. But is there any reason to believe that a tolerance of soil fungi in a very young seedling might translate to resistance as a full-grown plant?)

I have used mycorrhizae in my seedling mix. I have not run controlled test.
