Horticulture and grains - pests and diseases watch list

Watching out for unusual pests and disease symptoms is just one of the ways you can help protect Australia's horticultural and grains industries.

Pests and diseases that you have not seen before could be exotic to Australia. Some of the more serious exotic plant pests and diseases to watch out for are listed below and sorted by industry.

The pests and diseases listed have been identified as threats through Plant Health Australia's Industry Biosecurity Planning process. Where available, links to fact sheets and images are provided to help with the recognition of the pests and diseases. 

You can help by reporting any plant pests and diseases that you suspect are exotic to Australia on 1800 084 881 (for more information see Spotted something unusual? Report plant pests and diseases).
