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.

马铃薯是欧洲的主要作物（124亿欧元，2020年）。然而，它被认为容易受到各种害虫和土传病原体疾病的侵害。其中最重要的害虫之一是由念珠菌（Candidatus Liberibacter solanacearum, CLso）引起的斑马片病（zebra chip， ZC）。CLso细菌在马铃薯上的引入主要与病媒木虱cockerelli Bactericera （BC）的存在有关，造成了严重的产量损失和质量损失。干腐病、黑点病、银屑病等马铃薯主要采后病害是由土传病原菌引起的，在田间和贮藏中均有发生。所有这些潜在的威胁都可能导致。在马铃薯产业的重大经济损失和粮食损失中。欧洲对马铃薯进口和生产的监管框架非常严格。然而，全球化、气候变化、经济驱动因素以及政治背景（欧盟绿色协议减少50%农药的目标）正在威胁着新出现的马铃薯害虫的进入和采后储存中土壤传播的病原体疾病的发病率。PataFEST及其18个互补伙伴，包括与厄瓜多尔的国际合作，旨在：1)在分子水平上表征生态害虫传播途径，鉴定马铃薯对CLso和采后病原体的抗性品种；2)结合图像分析工具（移动应用程序）和人工智能预测模型等前沿数字技术，提供有效的收获前植物和土壤防治CLso病媒和土壤传播病原体的措施；3)开发采后技术（生物防治包衣液、可控大气贮藏和挥发性有机物（VOCs）传感器），控制土壤病原菌的发生，保持贮藏马铃薯块茎的品质。这些战略和技术将被纳入虫害综合管理方法，以在最后TRL5评估其绩效。
