Impact on environment
Can invade intact canopy native vegetation and has the potential to dominate the mid-tier canopy.
Control
Site Management
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: Dig out. Ringbark and leave to die standing if safe to do so.
Plant parts requiring disposal: Seeds.
Disposal options: Remove to greenwaste or landfill if practical.
Biocontrol
Biocontrol is currently not available for this species.
Community agrichemical control recommendations
Certified Handler/Experienced agrichemical user: Foliar spray seedlings with 5g metsulfuron-methyl per 10L of water and 20ml penetrant.
