Seeds dispersed by birds.
Impact on environment
Forms dense stands, displacing native vegetation and preventing seedling establishment. Dominates canopy, altering vegetation structure and diversity. May cause an allergic reaction in some people, often as a cross-reactivity to main allergens.
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: Dig out.
Plant parts requiring disposal: Seeds.
Disposal options: Remove to greenwaste or landfill if practical.
Check for presence of agents: Privet lace bug (Leptopha hospita).

Community agrichemical control recommendations
No qualifications: Cut stump and paste freshly cut base of stems with metsulfuron gel or ringbark stem and paste with metsulfuron gel.
Basic Growsafe certified: Cut stump and spray freshly cut base with 5g metsulfuron-methyl per 1 L of water.
Certified Handler/Experienced agrichemical user: Drill and inject trees with 10g metsulfuron-methyl per 1L of water if safe to do so. Drill 18mm holes (tangentially angled downwards) in a spiral up the trunk. For 50mm stems drill one hole. For 100mm stems drill two holes. For larger stems drill holes 150mm apart. Foliar spray seedlings with 5g metsulfuron-methyl per 10L of water and 20ml penetrant.
Large trees must not be ringbarked or drilled that are closer than 1.5 times the height of the tree from paths, walkways and property.
Trees over 4 metres in height should be removed by a qualified arborist.
Caution: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
