Before applying herbicide treatments, the City of Melville has considered the impact of control options on co-occurring native flora including trees, shrubs, geophytes, grasses and other native herbs and on fauna. The methods and chemical concentrations that we employ are considered Best Practice Management and are only applied when required and done in a safe and responsible manner.
The City of Melville is guided by regulatory advice from the Department of Health (DOH) and the Australian Pesticides and Veterinary Medicines Authority (APVMA) in relation to the use of glyphosate. The DOH advises that a recent review by the APVMA is that products containing glyphosate are safe to use, when used in accordance with the label instructions. The APVMA review considered the 2015 International Agency for Research on Cancer (IARC) assessment and concluded that the scientific weight of evidence indicates that exposure to glyphosate does not pose a carcinogenic or genotoxic risk to humans.
Guided by the APVMA and the DOH on the use of glyphosate, the City will continue to use glyphosate for weed control in selected areas in accordance with best practice procedures and in a safe and careful manner. All pesticides used by the City and its contractors are approved by the APVMA and are applied in accordance with the manufacturer’s instructions by staff who are trained in safe and proper application.
A fact sheet on Glyphosate Safety and Use is available should you wish to refer to it and details regarding the registration of products, registration and assessment of glyphosate are also available from the APVMA.
Please note that if requested by a resident, the City will avoid spraying adjacent to their property.
