If you do some targeted Google searches, you might find some info on how those various products interact. |
Just yesterday I got the same answer from both Ortho and Organic Labs Inc. (makers of Excel LG and Myco Stim). I was told by both that any killing of the soil based microbes would be minimal because the Daconil/chlorothanlonil is designed for foliage. Hopefully one of you will correct me if I'm wrong, but I believe I remember the mechanics of Daconil explained to me as providing a coating or protective barrier to the foliage.
The name has been changed from Daconil to Ortho Max Garden Disease Control and the label no longer has the "weather stick" logo, so I guess it rinses off more easily. I wonder if it's even still as effective.
