When

Application may occur at any time during daylight hours, providing weather and tide conditions are suitable. As these pest plants are difficult to control, two to three follow-up applications may occur over the next 12 months. It is unlikely that spraying will occur during game hunting season.

Notifications

If you would like to be notified when herbicide control will be carried out and/or:

  • have a consented water take
  • take water for domestic purposes in the operational area
