SHIRE OF IRWIN - A BRILLIANT BLEND
Weed control Weed Control
Weeds pose a significant threat to biodiversity in the Shire of Irwin by degrading natural bushland areas. They also impact on agricultural productivity and can affect human health and recreational activities.
The Shire uses a range of herbicides that comply with the Health (Pesticide) Regulations 2011. These regulations primarily relate to signage, notification and licensing.
Landholders responsiblities
All landholders, including Council, have a responsibility to manage weeds and pests on their own properties. Please make it your responsibility to be informed! It is important to ensure you are not contributing to the spread of these weeds into natural bushland areas or neighbouring properties.
Weed eradication programs
The Shire also conducts programmed weed eradication programs on roadsides, at the Port Denison foreshore and on several reserves. Reasons for this include asset protection, road user safety, fire mitigation and the control of introduced weed species.
The Shire aims to minimise the use of herbicides where possible. By frequently undertaking weed management on your own verge and keeping the verge well maintained, residents can actively assist the Shire and alleviate the need to spray the verge. This will assist with reducing the application of herbicide in front of your property.
