See the Umbrella tree fact sheet (PDF, 2.6MB) for herbicide control and application rates.

• Umbrella tree is not a prohibited or restricted invasive plant under the Biosecurity Act 2014. However, by law, everyone has a general biosecurity obligation (GBO) to take reasonable and practical steps to minimise the risks associated with invasive plants under their control.
• Local councils must have a biosecurity plan that covers invasive plants in their area. This plan may include actions to be taken on Umbrella tree. Some of these actions may be required under local laws. Contact your local council for more information.
