Biological control

Biological control of pests, weeds and diseases (pest) is an integral part of a successful Integrated Pest Management plan. Biological control is the management of a pest through the use of their natural enemies (biological control agent). A biological control agent is an organism such as a virus, insect or plant disease. The Department of Primary Industries and Regional Development:

  • works with landholders and grower/community/biosecurity groups on control
  • provides diagnostic services and information on prevention, management and treatment
  • provides biosecurity measures to prevent introduction, and to eradicate or manage current pests.

For advice on biological control search our website or contact our Pest and Disease Information Service (PaDIS).
