Seeds dispersed by wind and water. Vegetative spread from suckering.

Forms dense stands and suppresses vegetation through allelopathy. May alter nutrient cycling regimes and facilitate establishment of pest plant species.

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.

Community agrichemical control recommendations

No qualifications
Cut stump and paste freshly cut base of stems with metsulfuron gel

Basic Growsafe certified
Cut stump and spray freshly cut base with 1g 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

Safety notes

Large trees must not be 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.
