Conférence sur Xylella fastidiosa : 29-30 octobre 2019
Deuxième conférence européenne sur Xylella fastidiosa
Environ 350 spécialistes phytosanitaires du monde entier se sont réunis en Corse pour deux jours de discussions intensives sur la manière dont la science peut contribuer à trouver des solutions à Xylella fastidiosa, cet agent pathogène qui engendre des dommages environnementaux et économiques sérieux en Europe. Des centaines de personnes ont également pu suivre les débats via une rediffusion en direct de l'événement.
Les dernières découvertes issues des projets de recherche européens portant sur X. fastidiosa ont été présentés, en particulier les résultats du projet Horizon 2020 POnTE. La conférence a également constitué une occasion pour les participants de se familiariser avec les dernières avancées en la matière ainsi que les progrès accomplis dans d'autres activités de recherche en cours dans le monde. La conférence a également constitué une opportunité de discuter des moyens de renforcer la coordination et les synergies dans ce domaine.
Le programme comprenait des présentations et des discussions sur les données dispnibles et les connaissances les plus récentes concernant X. fastidiosa, ses plantes hôtes, les vecteurs ou encore les options de lutte contre cet agent pathogène. Les présentations et des extraits vidéos de la conférence sont disponibles ci-dessous.
Cette conférence a été organisée conjointement par l'EFSA, l’Institut national de Recherche agronomique français (INRA); l’Agence française de sécurité sanitaire de l'alimentation, de l'environnement et du travail (Anses); l’Office de l’environnement de la Corse (OEC) par l’intermédiaire du Conservatoire botanique national de Corse, les projets financés par l'UE (POnTE, XF-ACTEURS et CURE-XF EuroXanth) ainsi que le réseau Euphrescode coordination et de financement en recherche phytosanitaire.
