The good old '40s. Dad not only had nicotine sulfate (it was labeled Black Flag 40) but we also had a can of calcium cyanide for the gophers. It worked really well!

When I was growing up in Minneapolis in the ‘40s, 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.
