Where is the reference for the section on pryethrums as companion plants? Epizootic (talk) 05:17, 22 November 2007 (UTC)

Not too sure but should the sentence read pyrethrins attack the nervous system instead of Pyrethrum? Dmsar 18:54 12 Jul 2003 (UTC)

Yes, I think so too. Reworded. Now can someone fill in the details of synergised pyrethrins? All I know is that some compounds enhance the effects of pyrethrins, and that some pyrethrin formulations take advantage of this... Malcolm Farmer 18:58 12 Jul 2003 (UTC)

Ok, Malcom, isn't this becoming a separate article on pyrethrins??? Shouldn't we just split it and make a link? Dmsar 19:20 12 Jul 2003 (UTC)

Perhaps. I think there's more that can be said about pyrethrins (a chemical srtructure drawing, and I'm curious about how they work), and the pyrethrum article could use a photo of the plant, but we don't have that at the moment... Hey, this is Wikipedia - be bold and split the article if you want. If anyone objects they'll revert it (I won't) -- Malcolm Farmer 09:14 13 Jul 2003 (UTC)

I used to live in Kenya, and my parents farmed Pyrethrum. I heard that the difference between Pyrethrum and pyrethrins was that Pyrethrum had both right and left-handed (molecules ??) but only one was effective. Synthetic pyrethrins only contain one-hand - the correct one, naturally. Sorry to be so vague .. Wizzy…☎ 08:50, 24 October 2006 (UTC)

Well if I knew a nursery or a place, I'd run out and use my digital camera and make it so. It seems to work ok here on the articles I've written. Dmsar 09:20 13 Jul 2003 (UTC)

Thanks, Heron. I over-read the colors in my zeal to add info. the &laquo was just me trying to be cute and experimenting. The misspelling wasn't mine, but I did miss it. Dmsar 21:49 12 Jul 2003 (UTC)

Fine. I did wonder for a moment whether there was some chemical significance in those brackets. :-) -- Heron

[edit] Use in organic farming

Is the chemical called pyrethrum used in organic farming? What is its toxcity as it exists in residues on such organically produced food? Badagnani (talk) 05:20, 5 June 2008 (UTC)
