Physical control
Method: Dig or pull out.
Plant parts requiring disposal: Seeds and epiphytes in trees.
Disposal options: Remove to greenwaste or landfill if practical.
Biocontrol
Biocontrol is currently not available for this species.
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 2g metsulfuron-methyl per 1 L of water.
Certified Handler/Experienced agrichemical user: Drill and inject trees with 5g 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.
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.
