Import Requirement 9 - (Potatoes – Import Condition)


Prior to import, a ‘Notice of Intention to Import Plants or Plant Products into Tasmania’ must be submitted to the relevant Biosecurity Tasmania Operations Centre.  Importation must occur in compliance with general Conditions and Restrictions for Prescribed Matter in Part 2 of the Plant Biosecurity Manual Tasmania.

9         Potatoes – Import Conditions

A person must not import, or cause to be imported, any potatoes, except in accordance with the following:

I.         Imported potatoes or parts of potatoes intended for propagation must be in the form of tissue culture plantlets or minitubers and meet the requirements detailed in Explanatory Note 1.

II.       Potato tubers intended for processing or consumption must be free of all other potato plant parts and washed completely free from soil and other extraneous matter. The potato tubers will be subject to a barrier inspection by Biosecurity Tasmania at the port of entry and must be accompanied by a Plant Health Certificate or Plant Health Assurance Certificate signed by an approved person stating that:

(a)     The potato tubers were grown in a State, Territory or Country that can demonstrate freedom from Potato Cyst Nematode (PCN) (Globodera rostochiensis (Wollenweber) Behrens). [Validation of State, Territory or Country freedom will be on provision of survey data, the requirements of which are outlined in Explanatory Note 2. Where such freedom cannot be demonstrated, potatoes may be imported under the Area Freedom conditions outlined in Clause IV (a) and (b); and

(b)     The potato tubers were grown in a State, Territory or Country that can demonstrate freedom from Bacterial Wilt (Ralstonia solanacearum (Smith) Yabuuchi et al. (syn. Pseudomonas solanacearum (Smith)). [Validation of State, Territory or Country freedom will be on the provision of survey data, the requirements of which are outlined in Explanatory Note 3. Where such freedom cannot be demonstrated, potatoes can be imported under the Area Freedom conditions outlined in Clause V (a) and (b)]; and

(c)     The potatoes tubers meet the conditions of Import Requirement 46 - Tomato Potato Psyllid - Hosts and Vectors; and

(d)     The potatoes were produced from certified seed (to be accompanied by a Red Certification Label and PCN Soil Test Certificate if grown in Victoria) which was grown in a region where PCN and Bacterial Wilt have not been recorded; and

(e)     The potatoes were produced on a property that does not share agricultural equipment with any properties in another State, Territory, Country or area unless that State, Territory, Country or area meets all the conditions of this Import Requirement for freedom from PCN and Bacterial Wilt; and

(f)    The potatoes have been packed in clean (free from soil, extraneous matter or other residues) containers (bags, bins etc).

III.      The consignment must be accompanied by a statutory declaration signed by the grower stating that he/she complies with Clause II (d) above.

IV.     Where State, Territory or Country Freedom from PCN cannot be demonstrated as outlined in Explanatory Note 2, in addition to complying with Clauses II (b) to (e) the following documentation must be supplied to validate Area Freedom from PCN:

(a)     Complete survey data for PCN from all the potato crops within a defined growing Area plus a 20 km buffer zone surrounding the Area, covering the 3 years prior to the proposed potato tuber importation. Survey requirements are outlined in Explanatory Note 2; and

(b)     A PCN soil test from the paddock in which the potatoes were grown, conducted either pre-planting, during the growing season, or post-harvest (Explanatory Note 2).

V.       Where State, Territory or Country Freedom from Bacterial Wilt cannot be demonstrated as outlined in Explanatory Note 3, in addition to complying with Clauses II (a) and (c) to (e), the following documentation must be supplied to validate Area Freedom from Bacterial Wilt:

(a)     Complete survey data for Bacterial Wilt from all the solanaceous crops within a defined growing Area plus a 20 km buffer zone surrounding the Area, covering the 3 years prior to the proposed potato tuber importation. Survey requirements are outlined in Explanatory Note 3; and

(b)     A soil test for Bacterial Wilt from the paddock in which the potatoes were grown, conducted either pre-planting, during the growing season, or post harvest.

Consignments must be accompanied by a Plant Health Certificate.

EXPLANATORY NOTE 1:  Importation of potatoes for propagation

·          Tissue culture:  Sterile potato plantlets produced at a ViCSPA accredited tissue culture laboratory and accompanied by a copy of the Certificate of Accreditation; or as released from a Post-entry Quarantine facility.

·          Minitubers:  Generation 0’ material (minitubers, microtubers etc) produced at a ViCSPA accredited facility and accompanied by a Black Certification Label indicating material variety and generation and a copy of the Certificate of Accreditation of the minituber facility that produced it; or as released from a Post-entry Quarantine facility.

EXPLANATORY NOTE 2:  Survey requirements for PCN.

In order to demonstrate State, Territory, Country or Area Freedom from PCN, the following information is required:

(a)     A survey of all of the potato crops in the defined Area for which freedom from PCN is being claimed must have been completed over the 3-year period prior to the proposed importation. The survey should also encompass a 20km buffer surrounding the Area. One third or greater of the crops in the Area must be surveyed each year. Survey information must be accompanied by a map detailing the Area for which freedom from PCN is being claimed. If freedom from PCN is to be claimed, survey data must indicate no cases of PCN within the Area or the buffer zone over the 3-year period.

(b)     The National protocol for soil sampling and testing for PCN must be followed (Hinch, 1991. National sampling strategies and standards for detection of potato cyst nematode. In: Potato Cyst Nematode- Impact on Australian Horticulture and a Proposed National Strategy. Horticultural Policy Council Industry Report No 6, 1993, pp 127-131). The minimum acceptable sampling intensity under this protocol is deemed to be the collection of 200 x 10cm3 samples on a 10 x 10m grid pattern for every 2 hectares, providing a combined 2kg field sample from which a 500g sub sample of dried soil is processed. In order to declare freedom from PCN, no cysts will have been found in any of the samples over the entire three-year period of testing.

EXPLANATORY NOTE 3:  Survey requirements for Bacterial Wilt.

In order to demonstrate State, Territory, Country or Area Freedom from Bacterial Wilt, the following information is required:

(a)     A visual survey of all solanaceous crops within the defined Area for which freedom from Bacterial Wilt is being claimed will have been completed over the 3-year period prior to the proposed importation. The visual survey should also encompass a 20km buffer surrounding the Area. One third or greater of the crops in the Area must be surveyed each year. Any suspect plants will have been serologically tested for Bacterial Wilt. Survey information must be accompanied by a map detailing the Area for which freedom from Bacterial Wilt is being claimed. If freedom from Bacterial Wilt is to be claimed, survey data must indicate no cases of Bacterial Wilt within the Area or the buffer zone over the 3-year period. Specimens suspected of infection with R. solanacearum must be laboratory tested for the presence of the bacterium.
