Hmm, thanks for that Info I was under the impression the MOA was different between those two Group 11's.
Unfortunately not. You might find this article useful, from the American Phytopathological Society about the QoI (strobilurin) fungicides. A quote:
"All QoI fungicides share a common biochemical mode of action: they all interfere with energy production in the fungal cell. To be precise, they block electron transfer at the site of quinol oxidation (the Qo site) in the cytochrome bc1 complex, thus preventing ATP formation. The preceding sentence may "seem like Greek" to even the most knowledgeable crop consultant, but it contains an important point-that the mode of action of the QoI fungicides is highly specific. Of the millions of biochemical reactions that occur in the fungal cell, these fungicides interfere with just one, very specific biochemical site."
