This project will develop advanced molecular diagnostic methods and immunological tools for the detection of plant viruses, which can be expediently applied in both post entry quarantine (PEQ) (import) and market access (export) context. Generic tests that are cost effective and reliable for plant virus detection will help reduce biosecurity risks from importations of plant material to Australia and New Zealand.

What is the biosecurity problem? 

Current tests used to screen imported plant materials rely heavily on visual inspection of goods, which can be erroneous especially when there is low level contamination and/or symptomless infections (i.e. seed transmitted diseases) not visible to the naked eye. Also, the use of pre-described tests for defined lists of pathogens does not allow for the detection of unknown strains and/or genera of pathogens. To better protect Australia's plant industries, there is an urgent need of the development and implementation of advanced immunological and molecular tests that are sensitive, efficient and reliable.

The main outputs of this project are to:

• establish a partnership with Trans-Tasman research and development capability to develop, validate and apply diagnostic platforms to enhance biosecurity and border protection
   
• develop new diagnostic systems to support improvements in both Australian and New Zealand PEQ protocols, and
   
• enhance management of trade and biosecurity risks for the Australian grains industry and the New Zealand and Australian nursery industries

Who will be the end-users of this research?

Protocols delivered by this research will be applied to Import Health Standards as well as PEQ. Tests developed will be used by biosecurity diagnosticians in federal and state government agencies and by industry, both nationally and internationally. The protocol will be automatically made available to industry, Australian Quarantine and Inspection Services pathologists and Department of Agriculture, Fisheries and Forestry staff.
