Skeleton weed in Western Australia - management guide

This Management Guide has been designed to assist landholders and increase their capacity to manage and eradicate skeleton weed infestations on their properties and to prevent its further spread within the State. Without a coordinated program aimed at controlling spread, skeleton weed would now be much more abundant and widely established throughout the Wheatbelt.

Skeleton weed is a declared plant which can drastically reduce crop yields (more than 1 tonne/ha in cereals) by competing for moisture and nutrients (mainly nitrogen). 

Declaration categories and management implications

Skeleton weed is declared under section 22(2) of the Biosecurity and Agriculture Management Act 2007.

Area

Implications

C2

whole of the State except Narembeen and Yilgarn

  • eradicate infestations; destroy plants and prevent propagation each year, until no plants remain
  • prevent the spread of seed or plant parts
  • summer search is required 
  • winter control is required

C3

Narembeen and Yilgarn

  • manage infestations to prevent the spread of seed or plant parts
  • summer search is required
  • treat plants to prevent seed set
  • winter control is required to receive search assistance

All landholders need to prevent the movement of seed and/or root fragments from their properties in produce (grain, seed and hay), wool and machinery and vehicles.

​The skeleton weed program

The Skeleton Weed Program is a coordinated approach to manage skeleton weed in Western Australia. It is delivered by the Department of Primary Industries and Regional Development (DPIRD) under a service delivery arrangement with the Grains, Seeds and Hay Industry Management Committee. The Committee acts under the ‘Biosecurity and Agriculture Management Industry Funding Schemes (Grains) Regulations 2010’ to manage prioritised pests affecting the grains industry.

Services provided under the program are only available to landholders who contribute to the Grains Industry Funding Scheme through the sale of grain, seed or hay. Landholders not under the scheme but who have skeleton weed on their properties are still required to meet their obligations under the program but at their cost. 

Objective

Assisting Western Australian landholders to eradicate skeleton weed and to prevent its further spread within the State. 

Strategies

  • Improve landholders’ ability to find and eradicate skeleton weed.
  • Increase landholders’ awareness of skeleton weed as a highly undesirable weed.
  • Widely publicise descriptions and pictures of skeleton weed to help landholders identify infestations.
  • Inform landholders about the most up-to-date techniques available for the management and eradication of skeleton weed.
  • Encourage local grower groups (Local Action Groups) to participate in cooperative surveillance and reporting of infestations.
  • Encourage Local Action Groups to assist in the management and eradication of skeleton weed in their local areas.
  • Implement practical compliance regimes in affected areas.
  • Provide landholders with incentives to report infestations.
  • Provision of winter control treatments where landholders are compliant with program requirements

Our Program has very effective, well proven control methods for eradicating skeleton weed
– if YOU find it WE can treat it
