Weed profile: Parthenium weed

Parthenium weed

Parthenium hysterophorus

Parthenium is the greatest weed threat to New South Wales. It spreads rapidly. Contact with the plant or pollen can cause serious allergic reactions in people. It is dangerous to grazing animals, and reduces crop and land values. Endemic to an area of central Queensland covering 18 million hectares.

New South Wales has made keeping this weed out a top priority. Although harvesters are high-risk, outbreaks can occur from various sources including any machinery or vehicles that have been in parthenium weed areas of Queensland. The emphasis on keeping parthenium weed out of New South Wales rests with you, the owners and operators of cross-border machinery. Therefore the operators of all machinery, not just harvesters, have a duty of care to prevent their machines from spreading parthenium weed.

Status

  • Declared in NSW under the Noxious Weeds Act 1993 (view details)
