HORSE OWNERS have been warned to lookout for and remove Ragwort growing in their fields, given the toxic risk it poses to horses.

The British Horse Society is raising awareness of the common wildflower ragwort, which is often found thriving on wasteland, road verges and railway land.

It contains toxic compounds which can poison horses if eaten in any state and can damage the liver, resulting in severe disease and possibly even death.

Ragwort control is vital to stop the spread and the BHS has produced a toolkit that offers guidance on how to identify the plant, as well as how to remove it safely and effectively, and how to resolve issues with neighbouring landowners, including public bodies.

BHS welfare education manager, Emmeline Hannelly, said: “Ragwort has a bitter taste so horses don’t tend to eat it, however, when wilted or dried it becomes more palatable as it loses its bitterness but retains its toxicity. This is particularly dangerous for horses, especially if it is found in forage such as hay," she stressed. "Ragwort plays an important and significant role in the British ecosystem and the BHS does not advocate blanket removal of the plant, however it should be removed from areas with grazing livestock and horses, as well as forage production land.”

Horse owners are also being warned of the legal obligations, under the Weeds Act 1959, for landowners/occupiers to control the spread, if it poses a high-risk to land used for grazing or forage production.

Ragwort seeds can lie dormant for years so dealing with the issue as soon as possible will help decrease the risk of spread.

If ragwort is found growing within 50 metres of your land, this is deemed high-risk and the landowner/occupier should be contacted to discuss the risk and removal. Ragwort growing within 50-100 metres of your land is also deemed medium risk and it is recommended you contact the landowner.

If you are not getting the cooperation you need from a neighbouring landowner, then the only route to enforcement is through a formal complaint, raised under the Weeds Act, with your nation’s relevant public body.

The BHS is working with John Calder, of the Ragwort Alert Group to determine if a review of the complaint process is required. Contact, before the end of July, if you need help progressing a complaint this season.
