You could always try the original paleonicotinoid by soaking some old

seeds of Nicotiana tabacum should supply you with enough leaves to do
all your plants.

Just don't mention it to elf'n'safety...

Interesting. I buy nicotine solution for ecigarettes. Not particularly
cheap but not too bad. The one I get comes in 72mg per ml (in a
propylene glycol or vegetable glycerine base). This isn't the strength
used in the final liquid - that is usually reduced to between 5 and 36
ml depending on choice/nicotine addiction by adding flavouring and more
pg/vg ).

Any idea what sort of concentrations should be in an imaginary spray?

Not of course that I'm going to do it - purely hypothetical.
