Allow me to correct myself, as Christina points out, AChE appeared to spike in the conventional fields in August. A spike in AChE would be expected if there were even a minimal exposure to carbaryl, which was detected in the samples at that date. One of the other things I found disturbing was they apparently made no effort to define the source of the Carbaryl, It would have been unusual in a commercial corn AG exposure to the best of my knowledge.
