Nicotine sulfate canisters used to be readily available as greenhouse
fumigants. You poked a hole in the can, stuck in something in between a
sparkler and a punk, and the smoke would start rolling out.

If you look at the relative toxicity (LD50 Rat - dosage that will kill 50%
of the tested population), nicotine is pretty nasty - 50-60 mg/kg, versus
malathion at 800, Orthene (acephate) around 1000, Merit (imidicloprid)
around 2000.

You know, guys, aside from asking whether boiling destroys TMV (after all,
you burn it when you smoke it and yet you won't let a smoker touch your
orchids) nicotine concentrate is not really healthy for *you*.

Thats true, hense ''put some boiling water'' which deactivates TMV
which is actually the tobacco strain of ORV. I don t allow smokers
handling my plants also...

How about boiling the water gently for a minute? That would surely kill
the virus.
