Hi Everyone,
Asked this question on the Pests board and wasn't getting much input so thought I'd copy it here:
Does anyone have experience using antifungal spray while trying to maintain soil mycorrhizae?
Seems like any drench application will wipe out the beneficial spores. Any input would be appreciated.

Good question, I guess the answer would be which is the worst evil, less myco organism or a nasty fungus that can get out of control. I've gone so far as using bleach on my leaves to kill powdery mildew that got out of hand. I guess you gotta do what you gotta do. thats just my 2 cents. then again I never grew a world record either.

Tom,
Thanks for the detailed info. That table is a great resource. Looks like my Bayer spray will be safe.
