Although the Green Revolution was a milestone in agriculture, it was accompanied by intensive use of synthetic pesticides, which has raised serious concerns due to their impact on human and environmental health. This is increasingly stimulating the search for safer and more eco-friendly alternative means to control plant diseases and prevent food spoilage. Among the proposed alternatives, pomegranate peel extracts (PPEs) are very promising because of their high efficacy. In the present review, we discuss the complex mechanisms of action that include direct antimicrobial activity and induction of resistance in treated plant tissues and highlight the importance of PPE composition in determining their activity. The broad spectrum of activity, wide range of application and high efficiency of PPEs against bacterial, fungal and viral plant pathogens suggest a potential market not only restricted to organic production but also integrated farming systems. Considering that PPEs are non-chemical by-products of the pomegranate industry, they are perceived as safe by the public and may be integrated in circular economy strategies. This will likely encourage agro-pharmaceutical industries to develop commercial formulations and speed up the costly process of registration.
尽管绿色革命是农业领域的一个里程碑，但它伴随着合成农药的大量使用，由于其对人类和环境健康的影响，这引发了严重的担忧。这越来越促使人们寻找更安全、更环保的替代方法来控制植物病害和防止食物变质。在提出的替代方案中，石榴皮提取物因其高效性而非常有前景。在本综述中，我们讨论了其复杂的作用机制，包括直接抗菌活性和在处理过的植物组织中诱导抗性，并强调了石榴皮提取物的成分在决定其活性方面的重要性。石榴皮提取物对细菌、真菌和病毒植物病原体具有广泛的活性谱、广泛的应用范围和高效性，这表明其潜在市场不仅限于有机生产，还包括综合农业系统。鉴于石榴皮提取物是石榴产业的非化学副产品，它们被公众视为安全的，并且可以纳入循环经济战略。这可能会鼓励农业制药行业开发商业配方，并加快成本高昂的注册过程。
