Weed Spraying

As part of our roadside weed control program, Council uses a range of herbicides in accordance with the Biosecurity Act 2015. The most commonly used chemicals include:

• Glyphosate (Roundup)
• Metsulfuron-Methyl (Brush-Off)
•  Flupropanate (Tussock)
•  Triclopyr & Picloram (Grazon)
• Triclopyr, Picloram & Aminopyralid (Grazon Extra)

All applications are carried out by trained staff to ensure effective control while minimising environmental impact.

Weed Spraying Program Schedule

Our Pesticide Use Notification Plan sets out the process we follow to inform the community about pesticide use in the local area, including outdoor public places owned or controlled by Council.  

Council ensures that pesticides are applied to public places in a safe, responsible manner, minimising harm to the community and the environment. 

The plan allows members of the community to take action to avoid contact with pesticides, if they wish.

The following weeds have been identified as priorities for management within the Northern Tablelands Local Land Services region. They are categorised according to their risk rating under the NSW Biosecurity Framework.
