What you need to know
Although wonga wonga vine is not a legally declared pest plant, it may still be invasive in some situations. Consider lower-risk alternatives for your garden, such as native plants.
Disturbed forest, shrubland, coastal cliffs, rocky sites, gardens.
Seeds dispersed by wind. Vegetative spread from layering. Human-mediated dispersal through dumping of garden waste, deliberate plantings and movement of contaminated soil.
Impact on environment
Can form dense infestations and prevent native seedling recruitment.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
Method: Cut vines and leave upper stems to die in trees or dig out.
Plant parts requiring disposal: All parts (except vines if left to die in trees).
Disposal options: Compost in a composting weed bag or remove to greenwaste or landfill.
Biocontrol is currently not available for this species.
Community agrichemical control recommendations
For small infestations: Cut stump and paste freshly cut base of stems with metsulfuron gel.
Basic Growsafe certified:
For small infestations: Cut stump and spray freshly cut base of stems with 1g metsulfuron-methyl per 1L of water. Cut vines at waist height and foliar spray vines on the ground with 0.5g metsulfuron-methyl per 1L of water.
Certified Handler/Experienced agrichemical user:
For medium to large infestations: Cut vines at waist height and foliar spray vines on the ground with 5g metsulfuron-methyl per 10L of water and 20ml penetrant.
