Ragwort Facts

  • The plant is poisonous to livestock but reports of large numbers of deaths are unreliable or false and the scientific literature shows that incidents are rare.
  • Ragwort does not spread rapidly into fields from roadside verges. In fact the research shows that very few seeds travel more than a few yards.
  • There is no automatic legal requirement for UK landowners to control it. Under extreme conditions landowners may be ordered to do so but in the absence of this they need do nothing.
  • There is no evidence that handling ragwort leads to liver damage in people. In fact the research shows that the alkaloids in ragwort have to be eaten before they are converted into a dangerous form.
  • Horses cannot be poisoned by inhaling seeds from nearby sites. The seeds do not blow, far are not inhaled and the dose is to small to have any effects.
