Habitats

Forest.

Dispersal

Seeds dispersed by mammals, humans and possibly birds. Vegetative spread from stem fragments.

Impact on environment

Suppresses vegetation growth. Potential to compete with native vegetation and provide food resource to invasive mammals.

Control

Site Management

Cut and pull vines away from desirable trees and native plants before foliar spraying. 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.

Recommended approaches

Physical control

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

Biocontrol is currently not available for this species.

Community agrichemical control recommendations

No qualifications:

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.
