Description du projet
Pour une gestion efficace des maladies post-récolte de la pomme de terre
Les pommes de terre sont sensibles aux maladies post-récolte, qui entraînent des pertes économiques et un gaspillage alimentaire. Candidatus Liberibacter solanacearum (CLso) est à l’origine de la maladie de la chip zébrée, elle est introduite par le psylle Bactericera cockerelli. Des réglementations européennes strictes sont en place pour garantir la qualité et la sécurité des importations et de la production de pommes de terre. Mais des facteurs tels que la mondialisation, le changement climatique, les considérations économiques et le paysage politique augmentent le risque d’infiltration des organismes nuisibles et des pathogènes transmis par le sol. Le projet PATAFEST, financé par l’UE, permettra d’identifier des variétés de pommes de terre résistantes à CLso et aux pathogènes post-récolte en examinant les voies écologiques de propagation des ravageurs au niveau moléculaire. Il vise ainsi à prévenir la transmission des maladies par les plantes et le sol grâce à des traitements avant et après la récolte.
Objectif
Potato is a key crop in Europe (€12.4 billion, 2020). However, it is considered vulnerable to a variety of pests and soil-borne pathogen diseases. One of the most important pests is caused by bacteria Candidatus Liberibacter solanacearum (CLso), causing a disease known as zebra chip (ZC). The introduction of CLso bacterium on potato is mainly linked to the presence of the vector psyllid Bactericera cockerelli (BC) causing severe damage, both in terms of yield losses and quality. Main potato postharvest diseases as dry rot, black dot and silver scurf, are caused by soil-borne pathogens that have incidence in both field and storage. All these potential threats may result. in significant economic losses in the potato industry and food losses. The European regulatory framework for potato’s imports and production is very strict. However, globalisation, climate change, economical drivers, as well as the political context (EU Green Deal target of 50% pesticides reduction) are threatening the entrance of emerging potato pests and the incidence of soil-borne pathogen disease in postharvest storage. PataFEST and its 18 complementary partners, including the international cooperation with Ecuador, aims: 1) to characterise at molecular level the ecological pest spread pathway and identify potato disease resistance varieties against CLso and postharvest pathogens, 2) provide effective preharvest plant and soil treatments against CLso vector and soil-borne pathogens combined with other cutting-edge digital technologies such as image analysis tools (mobile app) and artificial intelligence predictive models; 3) develop postharvest technologies (biocontrol coating solution, controlled atmosphere storage and volatile organic compounds (VOCs) sensors) to control the incidence of soil pathogens and maintain the quality of potato tubers stored. These strategies and technologies will be incorporated into an Integrated Pest Management approach to evaluate their performance at final TRL5.
