This product used to be available at retail. Does anyone know where in the US this can be purchased now?

No longer on retail shelves. Nicotine is nasty stuff.

So, what is it you're trying to manage? Perhaps we can suggest something else that works.

The product registration has been canceled by the USEPA so this stuff can no longer be sold, legally, in the USA.

Yeah, it can be nasty, but I liked it because it was relatively organic and very specific and handled a lot of bugs. After a day or two, it was totally degraded. Right now I've been going after tomato worms with an organic spray, to which I add a few drops of bacillus t. This gets squash bugs and the worms at the same time.

It seems like nicoine is no more deadly than some of the other chemicals on the market;it's effects are just more immediately apparent...

I'm wondering if I could produce something similar by simmering tobacco in water...?

At one time, for some reason, some people did consider Nicotine Sulfate "organic" but it is as organic as arsenic and cyanide. Arsenic was at one time also considered as an acceptable organic pesticide and was marketed as Paris Green, but knowledgable people would not use that any more than the Nicotine Sulfate.

Back in '50 and '51 I sprayed trees, getting soaked several times a day. We used arsenate of lead and nicotine sulfate. Something in there must be a preservative. I'm 80 and still gardening. Every time we find something that works, the government bans it. cyanogas was another, yellowjackets in the ground. dead in minutes.
