BAA 2010-30 Draft review of hops

Draft review of policy for the importation of hops (Humulus species) propagative material into Australia

This Biosecurity Australia Advice (BAA) invites stakeholders to provide comments on the Draft review of policy: importation of hops (Humulus species) propagative material into Australia by 28 November 2010.

The draft report recommends risk management measures for the importation of Humulus species propagative material which meet Australia’s appropriate level of protection (ALOP).

Australia’s policy for the importation of hops propagative material was suspended in 2004 due to disease concerns, pending the outcome of a pest risk analysis (PRA).

Subsequently, the Australian industry requested Biosecurity Services Group (BSG) to develop import conditions for propagative material of Humulus species and their cultivars.

Biosecurity Australia has now reviewed the policy for the importation of hops propagative material, and prepared a draft PRA report which is available for comment until 28 November 2010.

This review has identified insect pests and pathogens of quarantine concern associated with hops propagative material (soil free dormant rhizome, foliage free dormant cuttings, tissue culture and seed for sowing) and proposed quarantine measures to manage the risks.

Biosecurity Australia considers that the risk management measures proposed in this draft PRA report will achieve Australia’s ALOP against identified pests. Specifically, the proposed risk management measures for the different propagative materials are:

Soil free dormant rhizomes and foliage free dormant cuttings

  • Hot water treatment (50 °C for 30 minutes), surface sterilisation (1% NaOCl for 10 minutes), growth in closed government quarantine  facilities of mother plants at 15–25 °C for a minimum period of six months for visual observation; and 
  • Molecular testing techniques including polymerase chain reaction (PCR) test for fungal pathogens, herbaceous indexing and enzyme-linked immunosorbent assay (ELISA) and/or PCR for viruses and viroids and generic nested primer PCR for phytoplasma.

Seed for sowing

  • Hot water treatment (50 ºC for 30 minutes), surface sterilisation (1% NaOCl for 10 minutes); fungicidal treatment and growth in closed government quarantine  facilities at 15–25 °C for a minimum period of six months; and
  • Molecular testing techniques including PCR test for fungal pathogens, herbaceous indexing and ELISA and/or PCR for viruses. 

Tissue culture

  • Growth in closed government quarantine facilities at 15–25 °C for a minimum period of six months for visual observation; and
  • Herbaceous indexing and molecular testing techniques including ELISA and/or PCR test for viruses and viroids and generic nested primer PCR for phytoplasma.
