Potato exports guide
A to B

Brazil

Seed potatoes (updated 6 October 2021)

Potato cyst nematode (PCN)

A consignment test for potato cyst nematode (Globodera rostochiensis and G. pallida) is required before export (PCN testing for export applies). There will be a charge for this test.

Growing crop tolerances

Inspector's instructions BZ/2008/01 apply.

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

  • Potato mop top virus (PMTV): NIL
  • Tomato black ring virus (TBRV): NIL

Tuber tolerances

Inspector's instructions BZ/2008/01 apply.

Minimum tolerances for seed export apply, except for:

  • Gangrene (Phoma foveata): NIL
  • Pink rot (Phytophthora erythyroseptica): NIL
  • Skin spot (Polyscytalum pustulans): NIL
  • Spraing (PMTV and TRV): NIL
  • Tomato black ring virus (TBRV): NIL
  • Potato Bulb mite (Rhizoglyphus spp.): NIL
  • Adhering soil: NIL (brushing required)
  • Powdery scab (Spongospora subterranea): 0%
  • Shrivelled or dehydrated tubers: 0%
  • Loose soil: 0.2%

Common scab (Streptomyces scabies), Black scurf (Rhizoctonia solani) for each disease:

Surface area Tolerance by weight
less than 1/16th surface area affected no more than 30%
1/8th to 1/16th surface area affected no more than 20%
more than 1/8th surface area affected no more than 1.5%

 Silver scurf (Helminthosporium solani)

Surface area Tolerance by weight
less than 1/16th surface area affected no more than 30%
1/8th to 1/16th surface area affected no more than 20%
more than 1/8th surface area affected no more than 2%
of which dehydrated or shrivelled 0%

A post harvest test for skin spot is required if seed potatoes are being exported between 1 December and 31 January. A nil tolerance applies.

See below for additional advice.

Other requirements

  • Import permit: required.
  • Bill of Lading is considered to be the date of dispatch. The phytosanitary certificate must be issued no more than 14 days before the date of dispatch.
  • Varieties: only varieties registered in Brazil will be accepted unless they are for trials.
  • Varietal purity: lots have to be 100% pure.
  • Size: sprouting should not be excessive.
  • Treatment: all tubers should be brushed.
  • Chemicals: tubers can be treated with an approved fungicide to control gangrene but no symptoms of gangrene should be present in the stock at inspection.
  • Labelling: a label in Portuguese must be attached to each bag stating all information also given on the official Scottish label.
  • 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.

Laboratory tests

 Samples from each consignment may be laboratory tested by the Brazilian authorities for (latent) infection with viruses, fungi and nematodes.

The following tolerances are applied for virus infection:

  • PVA, PMTV, TRV, TBRV: NIL
  • PVX, PVS and PLRV: 0% each
  • PVY: 3.0%
  • Total PVX, PVY, PVS and PLRV: 4.0%

Additional advice

The Brazilian authorities check imported lots for the presence of free-living nematodes (Pratylenchus spp.) and other common soil-borne organisms including potato bulb mites (Rhizoglyphus spp.) . All lots for Brazil should be brushed and (practically) free from soil.

No assurance can be given that a consignment which complies with Brazil's tolerance for silver scurf at inspection in Scotland will pass import inspection in Brazil. The disease can develop very rapidly across the tuber surface if environmental conditions are favourable for its development.

Exporters should be aware of these commercial risks when exporting to Brazil.

Ministry of Agriculture, Livestock and Food Supply Normative Instruction No. 12 of June 10, 2005 on tolerances applied for regulated non-quarantine pests, damages and mixtures of seed potatoes intended for production, importation and trading in the country.

Ministry of Agriculture, Livestock and Food Supply Normative Instruction No. 52 of November 20, 2007 on the establishment of a list of quarantine pests which are absent (A1) and of quarantine pests which are present (A2) in Brazil, amended by Normative Instruction No. 41 of July 1, 2008 and Normative Instruction No 21 on July 3, 2015. 

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

  1. DA5 The growing crops were officially inspected on (enter date) and were found to be free from Phoma foveata. 
    Note use DA5 +DA2 if stock lots have been treated for gangrene.
    Insert the following at 1.
    DA5 + DA2 The growing crops were officially inspected on (enter date) and were found to be free from Phoma foveata. In addition the potatoes in this consignment have been treated with (state chemical/concentration) to control Phoma foveata under official supervision. This chemical is approved for efficacy and safety by the Chemicals Regulation Directorate of DEFRA.
  2. DA5 The growing crops were officially inspected on (enter date) and were found to be free from Pink rot (Phytophthora erythroseptica), Skin spot (Polyscytalum pustulans) and Wart disease (Synchytrium endobioticum).
  3. DA5 The growing crops were officially inspected on (enter date) and were found to be free from Potato mop top virus (PMTV) and Tomato black ring virus (TBRV).
  4. DA1 The area of production is free from Ditylenchus destructor.
  5. DA5 + DA15 The growing crops were officially inspected on (enter date) and were found be free from (Globodera rostochiensis and G. pallida). Samples of soil from the land, in which the potatoes were grown, were drawn and tested prior to planting by the Scottish Government and revealed no trace of viable cysts of Potato Cyst Nematode (Globodera rostochiensis and G. pallida). In addition the lots to be loaded were identified and samples of soil obtained from each lot making up the cargo were tested for Potato Cyst Nematode. None of the samples from the lots revealed the presence of viable cysts of Potato Cyst Nematode. The shipment is free of Globodera rostochiensis and G. pallida, in accordance with the results of Official Lab Analysis number:
  6. R11 The tubers were brushed and are free of dirt and substrate.
  7. The lots or shipments of seed-potato were produced on fields under an official certification system approved by the National Plant Protection Organization - NPPO of Brazil.
