Science and Advice for Scottish Agriculture (SASA). The Scottish Government

Scotland (UK)
National Plant Protection Organisation. Certification Agency. SASA is A Division of the Scottish Government Agriculture and Rural Economy Directorate, our primary role is to provide scientific services and advice in support of Scotland’s agriculture and wider environment. Although much of our work is in support of arable agriculture we also provide services in food safety, wildlife management and crime whilst providing specialist advice to Scottish Ministers.

SASA’s remit:

  • Ensuring the quality of seeds and tubers, and new crop varieties;
  • Keeping field and horticultural crops free of damaging diseases;
  • Keeping serious pests of plants out of the UK and Scotland;
  • Acting as the Scottish Government's Inspectorate of genetically-modified crops;
  • Developing new and sensitive diagnostic tests for pests and diseases;
  • Preserving and maintaining a wide range of historic, heritage and other varieties of potatoes, cereals, peas and brassicas;
  • Monitoring the pesticide load in our diet, and the pattern of use of pesticides in Scotland;
  • Protecting wildlife against deliberate or accidental poisoning;
  • Understanding the ecology of important vertebrate species
