National Action Plan for Pests of Horticultural Crops

 

Horticulture is Australia’s third-largest agricultural industry. It includes fruit, vegetables, nuts, flowers, turf and nursery products.

Pests that damage horticultural crops include species of:

  • bacteria
  • viruses
  • fungi
  • insects
  • nematodes.

The National Action Plan for Pests of Horticultural Crops is under development.

The plan will be a nationally agreed approach to:

  • prevent the introduction of pests of horticultural crops
  • prepare for a response if a pest is detected in Australia.

Success of the plan depends on cooperation and collaboration between stakeholders. These include: 

  • importers
  • shipping businesses
  • agricultural industries
  • all levels of government
  • non-government organisations 
  • individuals
  • experts and research agencies.

Implementation schedule

The plan’s implementation schedule will include activities and projects from 4 action areas:

  • prevention
  • detection
  • response
  • cross-cutting (actions that fit into 2 or more of the first 3 areas).

We will review activities annually and document progress.
