Michael Phillips
asked:
But all this begs one big question:
How much do we undo of these mycorrhizal benefits when we use fungicides in the
orchard and vineyard? I dont know that it matters here if were talking captan
or sulfur, though maybe there are some gentle fungicides someone wants to point
out. Is there a balance point between the two where a minimal fungicide program
does not break the mycorrhizal chain?
As I understand it from long
discussions with Don Chapman, owner of Bio-Organics, fungicide drenches do the
most harm to mycorrhizae in the soil. Those sprayed on trees don't have as
much impact. I try to use fungicides like neem seed oil that act as
barriers to fungus spores, as opposed to fungicides that are taken up by plant
cells.

inoculates everything with mycorrhizal fungi and has the big harvests and
healthy plants to prove the power of
mycorrhizae.
