Potato Crop Effective Management Strategies to Tackle Future Pest Threats (PATAFEST)

马铃薯是欧洲的主要作物(2020年，124亿欧元)。然而，它被认为容易受到各种害虫和土壤传播的病原体疾病的影响。最重要的害虫之一是由假丝酵母(Candidatus Liberibacter Solanacearum，CLSO)引起的，它会引起一种被称为斑马片(ZC)的疾病。CLSO细菌在马铃薯上的引入主要与介体木虱公鸡杆菌(BC)的存在有关，在产量和品质方面都造成了严重的危害。马铃薯采后主要病害如干腐病、黑斑病和银屑病是由土传病原菌引起的，土传病原菌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。马铃薯产业的重大经济损失和粮食损失。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%杀虫剂的目标)正在威胁着新出现的马铃薯害虫的进入和采后贮藏中土传病原体疾病的发生。PataFEST及其18个互补伙伴，包括与厄瓜多尔的国际合作伙伴，旨在：1)在分子水平上表征有害生物生态传播途径，鉴定马铃薯抗病品种对CLSO载体和采后病原菌的抗性；2)结合其他前沿数字技术，如图像分析工具(移动APP)和人工智能预测模型，提供有效的采前植物和土壤处理；3)开发采后技术(生防涂层溶液、气调贮藏和挥发性有机化合物传感器)，以控制土壤病原菌的发生，维护马铃薯块茎贮藏的质量。这些战略和技术将纳入虫害综合管理办法，以在最后目标5评估其绩效。

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.
