Ragwort Poisoning


common ragwortDerek Smith of Ragwort-UK very kindly wrote me an informative article about Ragwort poisoning in October 2002. I've had about a dozen e-mails over the years from people worrying about how they should deal with the plant. Now, in September 2011, there's a lively debate about just how poisonous Ragwort is to stock and to humans who handle it.

I thought of adding a few footnotes to Derek's article in the interests of balance but really it's beyond my skills to chair an informed debate about Ragwort poisoning so I've withdrawn the article and you now need to refer to his website (see link below) to understand his approach to dealing with the plant. I don't keep animals, I don't have a background in biochemistry and I've never been involved in clearing Ragwort, except for the odd rosette that springs up on our lawn.

I'd also make a plea for its value in biodiversity. We've cinnabar mothjust come back from a weekend in Scotland and the moors were purple with heather and some of the rough field edges golden with Ragwort. It must make a huge contribution to Scottish insect life even though Highlanders dubbed the weed 'Stinking Billy' after William, Duke of Cumberland, or 'Butcher Cumberland' as they called him after the Battle of Culloden.
