Dale,
Since you are with Pioneer, I'd expect you to know that the natural
toxin created by the Bt soil bacterium, which is in an inactive form,
is different from the toxin created by the Bt corn plant, which is
already in activated form. Are you claiming you didn't know they are
different?

Stotzky has just very recently published a study showing that the Bt
corn toxin persisted in the soil for more than 243 days. This study
was widely posted on the Internet.
