The message
from "Mike Lyle" contains these words:

Another thing I found was that, as I think Rusty hinted, the
rhubarb-leaf stuff breaks down in the environment in twenty-four
hours. (I once tried boiling up some tobacco for garden purposes, but
the smell was so unbearable that I chucked it out.)

I used to grow tobacco, and cure the leaves. The baccy was good, too,
but I've given up smoking since. I did try making insecticide with the
waste, and it was effective, but didn't keep.
