Ragwort
We have a ragwort problem on our 100 hectare dairy farm. Can you offer some advice on how best to get rid of it. Thanks.

Ragwort (Senecio jacobea) was introduced to New Zealand as a garden plant in the 1870ís. It is mainly spread by seeds. The young plant is most toxic, however sheep will eat ragwort with no ill effects. Plants need to be continuously grubbed, just before flowering to exhaust their reserves. The Cinnabar Moth is also showing signs of promising biological control.
