For information on:

 

SASA provides the following scientific support on plant health to the Scottish Government in support of Scottish and EU plant health legislation. All plant health work is overseen by the Chief Plant Health Officer for Scotland (CPHOS).

If you wish to find out more information or contact us about a non-urgent plant health issue, please email Plant Health at SASA. For plant health inspections or urgent enquiries, refer to the section below relating to the Horticulture and Marketing Unit.

Further information on plant health can be found on the Scottish Government's Plant Health webpages or the Gov.uk website.

PLANT HEALTH ADVICE

SASA provides scientific, technical and policy advice to the Scottish Government on:

  • the implementation of plant health legislation;
  • contingency planning for eradication or containment of plant pests or pathogens;
  • risk assessments for plant pests and pathogens moving in or on traded plant material; and
  • all aspects of the technical and scientific services provided (below).

SASA staff also represent the Scottish Government and UK Plant Health Service nationally and internationally on committees, as editors and in consultancy work.

TECHNICAL SUPPORT AND SCIENTIFIC SERVICES

Horticulture and Marketing Unit (HMU)

HMU staff provide technical advice (see above) and undertake inspections to ensure compliance with:

HMU staff also support the implementation of the fruit and vegetable regime in Scotland.

For more information in relation to inspections, or to notify the appearance, or suspected appearance, of a harmful plant pest, please contact HMU.

Pests and pathogen diagnosis and surveillance -

  • Plant pathology - Viral, bacterial and fungal pathogens of plant health concern in Scotland are diagnosed on plants in trade. Surveillance for specific pathogens is also undertaken.
  • Pest identification - Entomological and nematological plant pests are identified in traded plant material, on plant products and on material subject to plant passporting.

Plant health licensing

SASA issues plant health licences on behalf of Scottish Ministers for work with organisms and materials that are normally prohibited under Plant Health legislation.

Plant health research

SASA undertakes research projects in support of plant health functions.

Potato quarantine

SASA runs the Potato Quarantine Unit on behalf of the UK Plant Health Authorities.

Pest and pathogen diagnosis and surveillance

Pest and pathogen diagnosis is an essential part of the plant health support for the Scottish Government and is the basis of much of the plant health advice given.

Quarantine and other pests and pathogens are diagnosed:

  • in traded plants (imported and exported plants and as required for plant passporting ) and plant products. Organisms for which surveillance is done include  Bemisia tabaci on Poinsettia plants, and Meloidogyne chitwoodii on potatoes and Plum pox virus on Prunus;
  • to meet requirements for surveillance by EC Member States in emergency legislation. Examples include Potato spindle tuber viroid (PSTVd, Commission Decision 2007/410/EC) and Phytophthora ramorum on host plants (2002/757/EC);  Pepino mosaic virus on tomato (2004/200/EC); Diabrotica virgifera on maize (2003/736/EC);
  • for potato quarantine testing (see the potato quarantine page);
  • for Scottish Government certification schemes (potatoes, soft fruit and bulbs);
  • on potato as required in the relevant control directives. This includes annual surveys for potato brown rot (Ralstonia solanacearum) and potato ring rot (Clavibacter michiganensis subsp. sepedonicus) as required in the EC Brown Rot Control Directive (98/57/EC as amended) and the EC Ring Rot Control Directive (93,85/EEC as amended). Surveys on ware land for potato cyst nematode (Globodera pallida and Globodera rostochiensis, 2007/33/EC) and other testing in Scotland to meet seed potato certification requirements (See the soil testing page for details of the sampling and testing for PCN);
  • wart (Synchytrium endobioticum) susceptibility testing of potato varieties as required in EC Wart Disease Directive (69/464/EEC);
  • as required for maintenance of protected zone status or to support statements on  pest freedom for example Bemisia tabaci surveillance, freedom from rhizomania (Beet necrotic yellow vein virus)

Samples from Scottish Government inspectors are examined for pests and pathogens using microscopic, microbiological, serological, molecular, electron microscopic and bioassay methods. SASA collaborates internationally to introduce and develop new techniques for the diagnosis of quarantine and other harmful organisms and is involved with EC evaluation of existing and new methods (see the R&D section).

Plant Health Licensing

SASA issues plant health licences on behalf of Scottish Ministers

 for the following activities in Scotland:

  • work with non-indigenous and quarantine plant pests and pathogens;
  • for work on certain imported soils and plant material;
  • for potato quarantine testing.

Licences are issued following inspection of premises and assessment of the risks associated with the activities, in accordance with EC legislation. Particular attention is given to the containment procedures to be used when handling the licensed material and its disposal on completion of the work.  Please see the guidance notes or email Plant Health Licensing for further information.

Download the application form for soil, plant material and prohibited organisms and send the completed form to:

The Plant Health Licensing Officer
SASA
Roddinglaw Road
Edinburgh
EH12 9FJ

For potato quarantine testing see the Potato Quarantine page or download the PQU Licence Application form.

The Scottish Government issues plant health licences for collection of wild plant material. Contact hort.marketing@gov.scot for further information.

For information on imports of plants and plant material, see the Plant Health Guide for Importers on the Scottish Government website.

SASA also provides advice to the Scottish Government in support of legislation on the contained use of genetically modified organisms.

Potato Quarantine

 

Entry of stolon- and tuber-forming Solanum material into the EU for further propagation is prohibited ( EC Plant Health Directive (2000/29/EC as amended). Material may, however, enter the EU under a derogation specified in Commission Directive 2008/61/EC. The material must undergo official post-entry quarantine testing.

In the UK potato quarantine testing is done at the UK Potato Quarantine Unit (UKPQU), a purpose-built facility at SASA.

A plant health import licence is required prior to import.

The UKPQU is overseen by a Review Committee  comprising stakeholders including the Scottish Government, the Department for Environment and Rural Affairs (DEFRA), Department of Agriculture and Rural Development for Northern Ireland (DARD-NI), British Society of Plant Breeders and research and commercial interests. The committee meets every several years. A report of the work of the UKPQU is prepared for these meetings and can be viewed here.

TESTING PROCEDURE

Each unit of potato material is established as in vitro microplant cultures, observed over a growing season in the glasshouse for the presence of diseases and tested for specific pathogens. The testing done by the UKPQU exceeds EC requirements. 

Material released by the UKPQU is issued with a plant passport and may be planted without further testing anywhere in the EC. You can obtain a copy of our testing procedures from the Potato Quarantine Unit

OTHER SERVICES

Virus elimination and rapid multiplication services are provided for customers.

The UKPQU has been involved in quarantine testing programmes for true potato seed from UK gene banks. Tested seed is held in the Commonwealth Potato Collection at the Scottish Crop Research Institute.

The UKPQU collaborates with other potato quarantine scientists internationally to develop new methods, evaluate existing methods for pathogen diagnosis for potato quarantine purposes and to develop guidelines for the safe movement of potato germplasm.

Plant Health Regulation

Plant Health elements of the Official Controls and Plant Health Regulations - GUIDANCE

The Official Controls Regulation (OCR) and Plant Health Regulation (PHR) became applicable in the UK from 14 December 2019 and are part of the Smarter Rules for Safer Food (SRSF) package. Although we are no longer a member of the EU, we are in a transition period where all EU laws will continue to apply.

What is Smarter Rules for Safer Food?

The Smarter Rules for Safer Food (SRSF) package is a set of EU regulations for the protection against animal disease and plant pests. The package will modernise, simplify and improve existing health and safety standards for the agri-food chain. It will take a risk-based approach to animal, plant and public health protection, introducing more efficient pest and disease control measures.

The package includes 3 principal EU regulations: 

The 3 principal EU regulations are supported by EU negotiated tertiary legislation that adds the detail to the legislation. The technical detail in the tertiary legislation can be updated quickly in response to changing situations and new technology. The Scottish Government has been working with Defra, the devolved administrations, the European Commission and other EU member states on the content of the tertiary legislation.

In order to ensure a co-ordinated approach to regulatory implementation is made across the UK, the Scottish Government and UK Government are working closely with delivery bodies, the devolved administrations and crown dependencies to ensure any new rules protect the UK’s biosecurity without putting any unnecessary burden on industry.

Plant Health Regulation

The Plant Health Regulation (PHR) became applicable in the UK from 14 December 2019 alongside the Official Controls Regulation.

The PHR helps the agricultural, horticultural and forestry sectors remain sustainable and competitive, as well as protecting domestic biodiversity and ecosystems. Globalised trade and climate change now present a greater risk to these sectors. The new PHR sets out controls and restrictions that will apply to imports and internal movement of certain plants, plant pests, and other materials like soil, to help reduce these risks.

Some of the areas changing include:

  • The use of plant passports is being extended to cover all plants for planting and the format of the plant passport label is changing.  New requirements for authorisation will also be introduced.
  • More goods being imported into the EU will require a phytosanitary certificate.
  • New requirements for the registration of professional operators.
  • Strengthened measures for protected zones.
  • New requirements applying to high risk plants and regulated non-quarantine pests (RNQPs).
  • A more precautionary approach to new trade flows and a commitment to undertake thorough pest risk assessments.
  • A new category of priority pests will be introduced, including annual surveying requirements and outbreak contingency planning.

Please see the plant passports page for more details.
