Demystify:
When I was growing up in Minneapolis in the =E2=80=9840s, our leftover "Victory
Garden" was across the street until they built houses there. We had room
to grow sweet corn and I remember my Dad treating the seed corn kernels with
nicotine sulfate. He said he wasn't sure if the pheasants from the
adjacent meadow wouldn't dig up the kernels before they sprouted because of the
stench or because they knew it was toxic. Of course I asked if it was
toxic was it still there when we ate the sweet corn in the summer. He said no,
there was none left in the ears by then.
Since my 1st two jobs out of grad school were in ag chem labs, I still have
copy of the Chemical Week Pesticide Register. Nicotine sulfate was listed
as a contact insecticide and fumigant in closed spaces. The LD50 is
50-60.

Another
good example is nicotine, which was registered for use as a pesticide until
2008, when the last remaining producer requested that EPA cancel the
registration. And we all know about its other uses, not exactly regulated
by EPA.
