Common Ragwort

What is it?

A native plant growing up to a maximum height of about a metre with flat clusters of bright yellow daisy-like flowers generally in late June, July and August. There are other plants that look similar so careful identification is important (see the Government's Code of Practice for information) The flowers are followed by dandelion-like seed heads and the seeds can be dispersed by the wind over a wide area.

All parts of the plant are poisonous and are a hazard to grazing livestock. Stock do not generally eat the plant in its green state but consume it when dried in feed. The effect is likely to lead to the death of the animal. It is particularly a problem for cattle, horses, ponies and donkeys.

Ragwort is specified as an injurious weed in the Weeds Act 1959 and primary responsibility for its control rests with the occupier of the land concerned. In view of the quantity of seeds produced by each individual plant and the wide area over which they may spread rapid action is necessary once a problem is identified.

No. Ragwort, as a native plant, is very important for wildlife in the UK. It supports a wide variety of invertebrates and is a major nectar source for many insects. In many situations ragwort poses no threat to horses and other livestock. It is a natural component of many types of unimproved grassland and is used by some invertebrate species that have conservation needs. However it is necessary to prevent its spread where this presents a high risk of poisoning horses and livestock or spreading to fields used for the production of forage. A control policy should be put in place where a high or medium risk is identified.

Land not controlled by Cornwall Council

If you are concerned about ragwort adversely affecting your land you should contact the landowner/occupier of the land with the ragwort. If they fail to take action in line with the Government's Code of Practice then you should follow the Government's advice.

NB Cornwall Council have no responsibility for the control of ragwort other than on land within its control.

Land controlled by Cornwall Council

If you wish to report ragwort on land controlled by Cornwall Council please contact the numbers below. 

On the highway - Cornwall Councils responsibility extends to the surface, including verges, but not boundary hedges. Reports should be made to our Customer Services on 0300 1234 222.

Long term control of ragwort will involve co-operation between neighbours and may require changes in land management/ grazing regimes.

Herbicides can be effective but detailed advice should be sought from a BASIS qualified adviser (most good agricultural merchants can provide this advice).

For further information about control measures please see the Government's code of practice on how to prevent the spread of ragwort.

Pulling

The normal short term measure is to pull the plants up when they are flowering but prior to seeding and burning.

Please note that all parts of the plant are toxic and protective gloves must be worn when handling the plant.

Whichever method of control is selected, remember not to turn grazing animals into the field until any treated Ragwort plants have died and totally disintegrated.
