Ragwort (Senecio jacobaea L.) is a biennial or perennial plant with daisy like flowers. It reproduces from its crown, roots and stems and invades regions of high rainfall, especially rundown pastures and farm land.

The whole plant is toxic to humans and livestock.

Control Tips

Gusto Woody and Noxious Weed Herbicide is registered to control Ragwort

When using Gusto in a Hand Gun Application:


  • The best time to spray Ragwort is in the Spring or Autumn when the plant is in the seedling or rosette stage
  • Thoroughly wet foliage, stems and the crown of the plant to the point of run off
  • Use a high quality non ionic wetting agent like Weed Forces Holdfast for best results, helping to improve wetting and herbicide penetration of the plant foliage

  • DO NOT spray when the plant is stressed (i.e. Drought, physical damage, insect damage etc)
