Fruit and vegetables represent a major source of food worldwide. However, pathogenic infection alone means more than one third of these products fail to reach the customer. Several economically important crops are grown largely in soil-less/hydroponic systems that can enhance production in a sustainable manner. However, hydroponic cultivation can encounter challenges with controlling pathogens. Current methods of control depend on the use of chemicals that are increasingly regarded as unsustainable. Therefore, it is urgent to develop alternative strategies to control diseases in a safe, environmentally friendly and sustainable manner. Research that exploits the plant's immune system to confer protection against diseases provides a sophisticated source for future IDM.The use of plant defence elicitors (i.e. agents of different origin that activate mechanisms of resistance) has recently emerged as a safer approach to reduce crop waste to diseases. Besides, little is known about the potential side effects of elicitors in nutrient intake, plant growth, fruit quality or their performance in more intensive commercial settings. In addition, our understanding of the molecular plant mechanisms of action is limited, which hinders their potential application to a wider market. Importantly, key aspects such the application methods, concentrations and formulations enhance the level of complexity for a successful implementation in hydroponic systems.

水果和蔬菜是全世界食物的主要来源。然而，仅病原体感染就意味着超过三分之一的产品无法到达客户手中。几种重要的经济作物主要在无土/水培系统中种植，可以以可持续的方式提高产量。然而，水耕栽培可能会遇到控制病原体的挑战。目前的控制方法依赖于使用越来越被认为是不可持续的化学品。因此，迫切需要制定替代战略，以安全、环境友好和可持续的方式控制疾病。利用植物的免疫系统来提供对疾病的保护的研究为未来的IDM提供了一个复杂的来源。使用植物防御激发子（即激活抗性机制的不同来源的试剂）最近已经成为减少作物废物对疾病的更安全的方法。此外，人们对诱导子在营养摄入、植物生长、果实品质或其在更密集的商业环境中的表现方面的潜在副作用知之甚少。此外，我们对植物分子作用机制的了解有限，这阻碍了它们在更广泛市场的潜在应用。重要的是，关键方面，如应用方法，浓度和配方提高了在水培系统中成功实施的复杂性。
