Though many of the would be Organic growers indulge in extremely
dangerous kitchen sink chemistry based on dubious recipes using
"natural" toxic ingredients on the web. Among the more dangerous ones
are those based on tobacco. It isn't all that hard to extract enough
nicotine from one or two cigarettes to kill a human if you use the right
solvent. And nicotine carries mosaic virus which is quite promiscuous in
the plants it will infect.

The use of nicotine is banned by law in any form of horticulture.

In favour of ones that fill the pockets of the agrochemical companies
and cause much worse damage to the environment. Yes, nicotine is
seriously poisonous, but that's not the reason it was banned. It
was banned because it isn't patentable, and no company was prepared
to spend 6 figures on getting it permitted.

And nicotine does NOT carry any form of virus, though tobacco may.
I have no idea whether alcohol extraction will kill the virus.
However, it is nonsense to worry about that too much, as the virus
is common in the UK and spread by aphids.
