Biosecurity Australia Advice 2011/02 - Importation of fresh taro corms from all countries
This Biosecurity Australia Advice advises stakeholders of the release of the Draft review of import conditions for fresh taro corms. Comments on the draft report are invited by 20 May 2011.
Quarantine requirements for the importation of fresh corms of taro varieties under the genus Colocasia from all countries have been in place for many years, requiring taro corms to be topped and free of all leaf material.
In 2006, Australia implemented emergency measures that prohibited the importation of small corm taro (Colocasia esculenta var. antiquorum) in response to concerns that they could be used as planting material.
Biosecurity Australia initiated a pest risk analysis (PRA) to assess the quarantine risk associated with imported taro corms. This meets Australia’s obligation under the International Plant Protection Convention and the International Standards for Phytosanitary Measures (ISPM No. 13) to review the emergency phytosanitary measures. The draft report has now been completed and is being issued for stakeholder comments.
Five quarantine pests have been identified as requiring additional quarantine measures to manage the risks to achieve Australia’s appropriate level of protection (ALOP). These include taro planthopper (Tarophagus proserpina), taro leaf blight (Phytophthora colocasiae), Colocasia bobone disease virus (CBDV), Taro vein chlorosis virus (TaVCV) and Tomato zonate spot virus (TZSV).
The proposed quarantine measures include:
- inspection of taro corms on arrival to ensure that consignments are free of quarantine pests and other regulated articles
- removal of all petiole material and growing points of the corm from large corm taro (Colocasia esculenta var. esculenta) imported from countries where taro planthopper, Colocasia bobone disease virus, Taro vein chlorosis virus or Tomato zonate spot virus are present
- only importing taro corms sourced from areas declared free of taro leaf blight
- prohibiting imports of small corm taro from countries where taro leaf blight, Colocasia bobone disease virus, Taro vein chlorosis virus or Tomato zonate spot virus are present.
