The laboratory's missions

The Plant Health Laboratory (LSV) is in charge of the identification of biological risks to plant health, the detection of genetically modified organisms, the determination of beneficial insects (which help protect plants) and insect vectors of disease, and the quarantine of plants introduced under import regulation waivers. Its missions cover cultivated land, forests, and natural environments.

The LSV is the National Reference Laboratory (NRL) for all plant pests. Three of its units are also European Union Reference Laboratories (EURLs), for fungi and oomycetes, insects and mites, and nematodes. Moreover, it quarantines plants introduced under import regulation waivers and coordinates assessments of biological risks to plant health. The LSV jointly leads the French plant health network (RFSV) and participates in numerous collaborative research and development projects. It is also actively involved in the work of the National epidemiological surveillance platform for plant health (ESV platform). The laboratory makes its data available to the platform as needed and provides it with scientific support in analytical fields.

The laboratory is regularly asked to carry out work and expert appraisals at national (formal requests and requests for support from the Directorate General for Food) and international (European and Mediterranean Plant Protection Organization, European Food Safety Authority, International Plant Protection Convention, etc.) levels.

A laboratory with several sites

The laboratory is spread out across six geographical sites:

  • Angers, in charge of bacteria, viruses, GMOs and the coordination of reference and expert appraisal activities relating to biological risks;
  • Clermont-Ferrand, which hosts the quarantine unit;
  • Montpellier, specialising in insects (pests, beneficial organisms and vectors) and invasive plants;
  • Nancy, in charge of fungi and oomycetes;
  • Rennes, focusing on nematodes, which are microscopic worms that can destroy crops;
  • Saint-Pierre (Reunion Island), specialising in tropical pests and pathogens.

Des citrons contaminés par la maladie des taches noires des agrumes

Improving identification of a fungal pathogen of citrus to prevent it from arriving in Europe

The Mycology Unit of ANSES's Plant Health Laboratory has developed a PCR test to distinguish the fungus responsible for citrus black spot from that of a recently discovered related species. This test will improve the ability to detect this pathogenic fungus, thus preventing it from being introduced into Europe.
