Mechanical, physical and cultural

Mechanical, physical and cultural control of pests, weeds and diseases (pests) are an integral part of a successful Integrated Pest Management plan.

Cultural controls are practices that reduce pest establishment, reproduction, dispersal, and survival. For example, crop rotation - replacing a susceptible crop with a less susceptible crop; and changing irrigation practices - less watering can reduce root disease and weeds.

Mechanical and physical controls kill a pest directly or make the environment unsuitable for it. For example, traps - for pest animals and insects; mulches - for weed management; steam sterilisation - for soil disease management; or barriers - such as screens or fences to keep animals and insects out.

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 control methods search our website or contact our Pest and Disease Information Service (PaDIS).
