由于抗药性的进化，合成农药控制农作物中的杂草、害虫和病原体的能力已经减弱。因此，可持续管理变得更具挑战性。需要新的解决方案，并且鉴于自然界中生物活性次生代谢物的普遍存在，此类化合物需要进一步探索，作为新型作物保护化学的先导。尽管人们对化感化学的了解有所提高，特别是在其用于杂草控制的潜力方面，但迄今为止，它们与多个生物界的相互作用主要是在单个化合物中进行研究，而不是作为一种反复出现的现象。在这里，通过定义对各种生物体的影响来介绍化感化学的多界效应，然后探索目前对这些化合物在进化军备竞赛和剂量反应关系方面的诱导性和可能的生态作用的理解。描述了在植物防御的多个方面具有功能益处的化感化学物质。将这些孤立的科学领域聚集在多界化感作用的统一框架下，鼓励开发天然化学物质，同时防御多种离散的生物胁迫，最大限度地提高杂草、昆虫和病原体控制的效益，同时潜在地规避耐药性。 © 2020 作者。 《害虫管理科学》由 John Wiley & Sons Ltd 代表化学工业协会出版。植物有潜力合成代谢物来防御多个王国；其他植物、动物害虫或微生物病原体的发育都可以被单一化合物抑制。
The capability of synthetic pesticides to manage weeds, insect pests and pathogens in crops has diminished due to evolved resistance. Sustainable management is thus becoming more challenging. Novel solutions are needed and, given the ubiquity of biologically active secondary metabolites in nature, such compounds require further exploration as leads for novel crop protection chemistry. Despite improving understanding of allelochemicals, particularly in terms of their potential for use in weed control, their interactions with multiple biotic kingdoms have to date largely been examined in individual compounds and not as a recurrent phenomenon. Here, multi‐kingdom effects in allelochemicals are introduced by defining effects on various organisms, before exploring current understanding of the inducibility and possible ecological roles of these compounds with regard to the evolutionary arms race and dose–response relationships. Allelochemicals with functional benefits in multiple aspects of plant defence are described. Gathering these isolated areas of science under the unified umbrella of multi‐kingdom allelopathy encourages the development of naturally‐derived chemistries conferring defence to multiple discrete biotic stresses simultaneously, maximizing benefits in weed, insect and pathogen control, while potentially circumventing resistance. © 2020 The Authors.

Plants have potential to synthesize metabolites for defence against multiple kingdoms; development of other plants, animal pests or microbial pathogens may all be inhibited by a single compound.
