What are the rules?

Advisory

The Bay of Plenty Regional Council does not enforce the control of advisory species. It is landowner/occupier responsibility to manage these pests. Council may provide advice on how to manage or control these species if required.

How do you get rid of it?

Recommended:

  1. Dig out small plants.
  2. Stump treat larger plants year around with herbicide. Treat ends of cut branches if they are left on site.
  3. Frilling (big stems only) in summer/autumn with herbicide.

Stumps often resprout even after treatment. Follow up treatment will likely be required.

 

CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and directions for the purchase, use and storage of the product, are followed and adhered to.
