Parthenium Weed colonises heavily stocked pastures and disturbed areas, reducing pasture production and causing health problems. It is a major pest plant in Central Queensland with the potential to spread to rangelands and summer cropping areas. It costs the Queensland beef industry in excess of $16 million per year and is estimated to cost Queensland Grain producers $6 million per year.
Currently, large infestations are found in Central Queensland, with serious outbreaks in the south and west of the State. The Taroom Shire is located on the Parthenium Buffer Zone. The Council aims to eradicate all isolated Parthenium outbreaks in the Nathan Catchment, and control all isolated outbreaks outside the Nathan Catchment.
Parthenium is a success reproducer. 1 plant can produce 15000 seeds. It can germinate, grow and set seed in just 28 days. Seeds are viable for 2-6 years (up to 20 years). The seeds are easily spread by water, machinery, animals, utes, people, fodder and grain movement.
Prevention and Control: The best prevention is to be aware of how, why and where Parthenium grows. Help with identification and control is available from Council or Landcare.
