It proposes methods for official adoption by the Ministry of Agriculture and coordinates the revision of analytical protocols. It calls on a network of 20 approved laboratories responsible for first-line screening.
The Bacteriology, Virology & GMO unit has five National Reference Laboratory (NRL) mandates in its three fields of competence. As part of its mandates, it carries out expert appraisal work to help the authorities make decisions; it also develops and validates official analytical methods and coordinates a network of approved laboratories by regularly organising inter-laboratory proficiency tests. Still as part of its mandates, it performs numerous specific analyses for regulated and emerging organisms and has developed a diagnostic service in bacteriology and virology aiming to prevent any new emerging threats.
The unit's five NRL mandates are as follows:
The Entomology and Invasive Plants unit has two National Reference Laboratory mandates.
Every year, it identifies thousands of samples belonging to over 500 different taxa. Based on this experience, it develops tools for the identification of insects and mites using morphological or molecular (barcoding) methods. This activity enables it to contribute greatly to the drafting of methods at European or international level (European and Mediterranean Plant Protection Organization, International Plant Protection Convention). It is a partner of research programmes, for example on vectors of plant diseases and on current plant health crises (Xylella, Epitrix, etc.).
This NRL is involved in epidemiological surveillance and phytopharmacovigilance activities focusing on emerging invasive plants, in France and other countries, which may constitute threats to plant health. It provides support to the National Biological Surveillance (SBT) network, run by the Ministry of Agriculture. In this framework, it develops and improves protocols for monitoring weed flora, analyses and interprets data, and participates in the scientific promotion of the results. The NRL develops knowledge on the biology, ecology and impact of these emerging invasive plants. These data are taken into account in pest risk analyses (PRAs) and also improve knowledge of invasion factors.

This NRL develops and validates reference methods aiming to detect the quarantine fungi and oomycetes listed in the European Plant Health Regulation, directly in the plants they parasitise. The new methods it develops aim to provide high analytical performance and very rapid results. The NRL trains and supervises a network of approved laboratories for the implementation of some of these methods, by regularly organising training courses and inter-laboratory proficiency tests.

This NRL carries out expert appraisal activities for public decision-making; it also performs analyses and coordinates networks of approved laboratories for the detection of plant-parasitic nematodes. It develops analytical and detection methods in its sphere of competence. Its analytical activities are focused on detecting nematodes of importance, whether officially regulated, included on quarantine lists, or emerging in France or third countries, which potentially pose a risk to plants in France.

This NRL manages an active network of five laboratories approved for the detection of plum pox virus based on the official method using the enzyme-linked immunosorbent assay (ELISA) technique. It has revised this method, and the method enabling it to confirm the results, twice. The unit assesses laboratory proficiency every two years.
For the other two types of viruses, the NRL itself performs official analyses.

The Tropical Pests and Pathogens (RAPT) unit has two National Reference Laboratory mandates:
These mandates provide it with a scope of action covering all of overseas France, the Indian Ocean area (as part of regional cooperation), metropolitan France and, more broadly, the European Union, for issues shared with tropical regions, in particular those affecting the citrus fruit sector. The NRLs have also developed international partnerships (South Africa, Australia, etc.).

This EURL coordinates a network of 26 National Reference Laboratories, which it informs of diagnostic advances through workshops, training, and literature monitoring. It promotes analytical methods for the detection of priority quarantine fungi and oomycetes in the European Union. Lastly, it organises training sessions and inter-laboratory tests, to ensure they are correctly implemented in all Member States. It provides these MSs’ National Reference Laboratories with access to a collection of reference strains. See the website of the EURL for fungi and oomycetes
This EURL, in consortium with the Institute for Sustainable Plant Production of the Austrian Agency for Health and Food Safety (AGES, Vienna, Austria), coordinates a network of 27 National Reference Laboratories (NRLs) in the European Union. Its role is to ensure the accurate identification of regulated and invasive insect and mite species. The consortium can rely on broad knowledge for the morphological identification of Coleoptera, Lepidoptera, Diptera, Thysanoptera, Hemiptera and Acari. Molecular diagnostics (e.g. barcoding and PCR assays) supplement morphological identification and improve accuracy. The EURL ensures the proper use of reference methods, disseminates technical information, organises annual proficiency tests, and trains NRL personnel. The species monitored more particularly are Spodoptera frugiperda, Epitrix spp., Thrips palmi, Agrilus planipennis, Bactrocera zonata and Bactrocera dorsalis. See the website of the EURL for insects and mites
The European mandate for nematodes is held in consortium with the Flanders Research Institute for Agriculture, Fisheries and Food (Belgium). Its activities aim to provide scientific and technical support to the European Commission and the NRLs in the different European Union Member States, for the implementation of the European plant health regulations. It provides the knowledge and tools required to ensure the high-quality, uniform and reliable detection and identification of regulated and emerging plant-parasitic nematodes. In this capacity, the EURL coordinates the network of European NRLs. See the website of the EURL for nematodes
