Control methods for golden dodder (Cuscuta campestris) a declared pest in Western Australia.

REPORT THE PRESENCE OF THIS PEST BEFORE UNDERTAKING CONTROL

Information about this pest can be found on the golden dodder: declared pest page.

Slashing or manual removal is not successful as it spreads the golden dodder. Remove the host plants and then have a program for at least four to five years to control growth of the host plants or any susceptible broadleaved plants.

Chemical requirements

When using any agricultural chemicals please ensure that you always follow instructions on the label and any permit. Users of agricultural chemical products must always strictly comply with the directions on the label and the conditions of any permit. To view permits or product labels go to the Australian Pesticides and Veterinary Medicines Authority website.

Chemical control options

Chemical control options can be found below. For other methods of control please refer to the declared plant control handbook.

Recommended herbicides        

  • Glyphosate
  • Paraquat + diquat
  • Triclopyr + picloram                                   

Herbicide: Glyphosate (Group M) (various trade names: see APVMA link)

Active ingredient

  1. Glyphosate 360g/L
  2. Glyphosate 450g/L    
  3. Glyphosate 540g/L

Other concentrations of glyphosate are available

Rate of product/10L water

  1. Glyphosate 360g/L = 100mL
  2. Glyphosate 450g/L = 80 mL
  3. Glyphosate 540g/L = 65 mL

Adjust rates when using another concentration of glyphosate

Time of application

Prior to flowering

Wetting Agent

Non ionic @ 1mL/L of water

Remarks

  • This is a non selective treatment as all vegetation will be controlled.
  • Repeat applications are necessary.
  • Paraquat + diquat @ 100mL/10L water can be used in place of glyphosate but this can only be applied by licensed spray contractors.

Herbicide: Triclopyr + picloram (Group I) (various trade names: see APVMA link)

Active ingredient

Triclopyr 300g/L + picloram 100g/L              

Rate of product/10L water

100mL

Time of application

Actively growing host plants

Wetting Agent

Pulse® @ 25mL/10L water

Remarks

  • Treat an area of 5m beyond the weed patch, and repeat annually or when broadleaved plants appear. This will give a grass dominant site. If a woodland site, replant to native species.
  • If area is arable, crop to cereals as these are not attacked by the golden dodder. The crops may have to be treated with in-crop herbicides to control broadleaved weeds.
