Biological control
Biological control involves the release of a weed plant's natural enemies. These enemies, known as biocontrol agents, can limit a plant's growth, reproduction and spread by affecting various parts of the plant and different stages of a plant's lifecycle.

Roadside weed management
Roadsides can provide valuable native habitat but may also become a pathway for the spread of weeds. Weed control is needed on road reserves to reduce fire hazard, maintain visibility, protect native vegetation and prevent the establishment and spread of weeds along road corridors and into new areas.
The management of weeds on roadsides must comply with a range of legislation, including the Landscape South Australia Act 2019.
The roadside weed management manual includes information about the need for and benefits of roadside weed management, roles and responsibilities of stakeholders, a framework to guide best practice, and summaries of the relevant legislation and legal requirements.
