Philippines

Seed potatoes (updated 16 July 2019)

Export of seed potatoes to the Philippines is only allowed if an application for an import permit is approved.

The import permit will state the exact phytosanitary requirements which may be different from those listed below. 

Growing crop tolerances

Class tolerances apply, except if the tolerances below are stricter:

  • PVX & PVY: NIL 

Tuber tolerances

Minimum tolerances for seed export apply. 

Other requirements 

Import permit: required. 

Chemicals: the seed potatoes might have to be treated with a broad spectrum fungicide (see Import Permit). 

Packaging: If wood packaging is used (e.g. boxes, pallets), this should be treated and certified. Wood material should comply with International Standards for Phytosanitary Measures (ISPM 15) on wood packaging materials. 

Additional declarations to be inserted on the reverse of the phytosanitary certificate for seed potatoes

  1. Samples of soil from the land in which the potatoes were grown were drawn and tested by the Department prior to planting and revealed no trace of Potato cyst nematodes (Globodera rostochiensis and G. pallida).
  2. Potato wart disease (Synchytrium endobioticum) is not known to have occurred on the land in which the potatoes were grown.
  3. At the time of visual inspection there were no visible signs of Potato Virus X and Potato Virus Y.
  4. Potato spindle tuber viroid (PSTV), Potato ring rot (Clavibacter michiganensis ssp. sepedonicus) and Potato brown rot (Ralstonia solanacearum) are not known to exist in Scotland.
  5. The tubers are practically free from soil.
  6. The tubers listed overleaf are derived from initial material which form the basis of the Scottish Seed Potato Classification Scheme. They have been tested and found free from the diseases listed below and have been subsequently maintained in conditions which ensure that the material remains free. Every other year material from each clone is field planted to inspect for any variation to type. 

Disease testing carried out:

  1. Viroids: Potato spindle tuber viroid tested by c-DNA Probe
  2. Viruses: PVA, PLRV, PVM, PVS, PVY and PVV tested by DAS ELISA; PVX tested by Chloroplast Agglutination; Sap is also inoculated onto the following indicator plants: Capsicum annuum, Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Datura metel, Nicotiana clevelandii, Nicotiana debneyi, Nicotiana tabacum cv White Burley
  3. BacteriaRing rot (Clavibacter michiganensis ssp. sepedonicus) tested by inoculation of tuber heel end sap into egg plant (Solanum melongena); Potato brown rot (Ralstonia solanacearum) tested by semi-selective medium and PCR; Pectolytic Erwinia spp. tested by maceration of in vitro plants in enrichment media, incubating anaerobically and then plating onto a pectate medium.

Ware potatoes

Export of ware potatoes to the Philippines is only allowed if an application for an import permit is approved. The import permit will state the exact phytosanitary requirements which may be different from those listed below. 

Wart disease

Potato wart disease (Synchytrium endobioticum) must not be known to have occurred in the field where the potatoes were grown.

Potato cyst nematodes (PCN)

The field in which the potatoes were grown must have been tested for the presence of Potato cyst nematodes (Globodera rostochiensis and G. pallida) pre-planting or where this has not been carried out lot freedom from PCN using a consignment test must be demonstrated (PCN testing for export applies). There will be a charge for these tests.

Tuber tolerances

Minimum tolerances for ware export apply.

Other requirements

Import permit: required.

Chemicals: the ware potatoes might have to be treated with a broad spectrum fungicide (see Import Permit).

Packaging: If wood packaging is used (e.g. boxes, pallets), this should be treated and certified. Wood material should comply with International Standards for Phytosanitary Measures (ISPM 15) on wood packaging materials.

Additional declarations to be inserted on the reverse of the phytosanitary certificate for ware potatoes

  1. Samples of soil from the land on which these potatoes were grown were drawn and tested prior to planting by the official services and no trace was found of Potato cyst nematodes (Glodobera pallidaandG. rostochiensis) or lot freedom from PCN has been demonstrated by consignment test.
  2. Potato Wart Disease (Synchytrium endobioticum) is not known to have occurred on the land in which the potatoes were grown.
  3. Potato spindle tuber viroid (PSTV), Potato ring rot (Clavibacter michiganensis ssp. sepedonicus) and Potato brown rot (Ralstonia solanacearum) are not known to exist in Scotland.
  4. The tubers are practically free from soil.
