The message
from Ann contains these words:

Jangchub expounded:

Ann, Janet said the pesticidal properties were in the leaves of the
marigold, which she said was pyrethrum. That is not true, and
inaccurate. It is not a common marigold which produces the pesticide
pyrethrum, but the mum and the pesticide is in the flowers not stems
of foliage.

Yea, V, I saw that further down the thread. I've always known
pyrethrum to be derived from mums, also. A google search does not
turn up any mentions of marigolds producing pyrethrins at all.

I gave the link, twice :-)

Regardless, Janet. The pesticide pyrethrum comes from the flower not
the foliage and smell has absolutely nothing to do with its
insecticidal properties in that it kills insects indiscriminately.
Kill is kill. I don't kill knowingly. And no, I don't eat meat
either.
