Management Notes (for the Swan NRM Region)
General Biology. Growth form. Vine. Life form. Annual. Reproduction. Dispersed by wind, water, animals, and machinery and planting material contaminated by dodder seeds. Seed production is prolific with up to 1,600 seeds per plant. Seedbank persistence. Up to 50 years.
Notes. Annual, leafless, parasitic plant. Yellow, thread-like stems (up to 0.8 mm) that twine around its host plant. It lacks normal roots and leaves but does bear flowers and fruits. Seeds are viable and germinate readily but can only survive the seedling stage if they get a host immediately after germination..
Additional information. Origin. Native to North America and parts of the Caribbean. Similar exotic species. Cuscuta pentagona and Cuscuta tasmanica.
Suggested method of management and control. All host and dodder plant material must be burnt, preferably on the infested site. Cut the host plant as close as possible to ground level and burn it. Burning can be carried out after cutting and drying. Burning is more effective following the application of a desiccant herbicide. Metsulfuron-methyl 300 g/kg + Aminopyralid 375 g/kg (Stinger™) Rate: 2 g in 100 L of water Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
