Draft pest risk analysis report for ‘

Acronyms and abbreviations

Summary

The pest risk analysis meets Australia’s obligations under the International Plant Protection Convention and the International Standards for Phytosanitary Measures (ISPM No. 13) to review emergency phytosanitary measures that were put in place on 6 June 2008 and revised on 4 December 2008.

The pest risk analysis has identified potato tubers, nursery stock and tomato-potato psyllid infected with ‘Ca. L. psyllaurous’ as potential pathways for the introduction of ‘Ca. L. psyllaurous’ with an unrestricted risk that exceeds Australia’s appropriate level of protection (ALOP).

This draft pest risk analysis report recommends that additional measures be applied to fresh fruit and nursery stock of plants in the Solanaceae family being sourced from areas where ‘Ca. L. psyllaurous’ is known to occur.

A combination of risk management measures and operational systems are proposed to reduce the risks associated with the importation of potato tubers, nursery stock and infected tomato-potato psyllids. Specifically, the proposed measures are:

For potato tubers:

• 
  area freedom or
  
• 
  processing in quarantine approved premises.
  

• 
  area freedom or
  
• 
  post-entry quarantine and testing for ‘Ca. L. psyllaurous’.
  

• 
  area freedom or
  
• 
  systems approach for fruit with pre- and post-harvest measures:
  

− washing and brushing to remove all life stages of the psyllid on the fruit or

• 
  application to fruit of a treatment known to be effective against all life stages of the psyllid (including but not limited to methyl bromide fumigation)
  
• 
  methyl bromide fumigation of nursery stock and
  
• 
  supporting operational systems to maintain and verify phytosanitary status.
  

Biosecurity Australia will consider any comments received in finalising the pest risk analysis and quarantine policy recommendations.
