Review: Importing Phytophthora ramorum host propagative material

April 15, 2015

Stakeholders are invited to provide comments on the ‘Draft review of policy: importation of Phytophthora ramorum host propagative material into Australia’ by 29 April 2015.

The review was initiated following a request from the nursery industry to revise the import conditions for nursery stock from countries where P. ramorum is known to occur. Surveys overseas have identified several new species of Phytophthora including P. kernoviae, P. nemorosa and P. pseudosyringae which share a similar host range, geographic range and cause symptoms indistinguishable from those of P. ramorum.

P. ramorum is the most destructive pathogen of oaks and a range of other host plants with significant commercial value, causing direct host mortality and increasing the cost of production due to its regulatory impact. The Department of Agriculture has therefore undertaken a comprehensive analysis of the scientific literature to review the appropriateness of the existing policy for the importation of propagative material for these Phytophthora hosts.

Comments on the draft report should be submitted by 29 April 2015.

The draft report is available at Biosecurity Risk Analysis.
