Plant essential oils (EOs) are gaining interest as biopesticides for crop protection. EOs have been recognized as important ingredients of plant protection products including insecticidal, acaricidal, fungicidal, and nematicidal agents. Considering the growing importance of EOs as active ingredients, the domestication and cultivation of Medicinal and Aromatic Plants (MAPs) to produce chemically stable EOs contributes to species conservation, provides the sustainability of production, and decreases the variations in the active ingredients. In addition to these direct effects on plant pests and diseases, EOs can induce plant defenses (priming effects) resulting in better protection. This aspect is of relevance considering that the EU framework aims to achieve the sustainable use of new plant protection products (PPPs), and since 2020, the use of contaminant PPPs has been prohibited. In this paper, we review the most updated information on the direct plant protection effects of EOs, focusing on their modes of action against insects, fungi, and nematodes, as well as the information available on EOs with plant defense priming effects.
植物精油作为用于作物保护的生物农药正越来越受到关注。精油已被公认为是植物保护产品的重要成分，包括杀虫剂、杀螨剂、杀菌剂和杀线虫剂。鉴于精油作为活性成分的重要性日益增加，对药用和芳香植物进行驯化和种植以生产化学性质稳定的精油，有助于物种保护，确保生产的可持续性，并减少活性成分的差异。除了对植物病虫害有这些直接影响外，精油还能诱导植物防御（引发效应），从而提供更好的保护。考虑到欧盟框架旨在实现新型植物保护产品的可持续利用，并且自2020年以来已禁止使用有污染物的植物保护产品，这一方面具有重要意义。在本文中，我们综述了关于精油直接植物保护作用的最新信息，重点关注其对昆虫、真菌和线虫的作用方式，以及具有植物防御引发效应的精油的相关信息。
