Global agricultural systems are under increasing pressure to deliver sufficient, healthy food for a growing population. Seasonal inputs, including synthetic pesticides and fertilizers, are applied to crops to reduce losses by pathogens, and enhance crop biomass, although their production and application can also incur several economic and environmental penalties. New solutions are therefore urgently required to enhance crop yield whilst reducing dependence on these seasonal inputs. Volatile Organic Compounds (VOCs) produced by soil microorganisms may provide alternative, sustainable solutions, due to their ability to inhibit plant pathogens, induce plant resistance against pathogens and enhance plant growth promotion. This review will highlight recent advances in our understanding of the biological activities of microbial VOCs (mVOCs), providing perspectives on research required to develop them into viable alternatives to current unsustainable seasonal inputs. This can identify potential new avenues for mVOC research and stimulate discussion across the academic community and agri‐business sector.

利用微生物挥发物代替农药和化肥。

全球农业系统面临着越来越大的压力，需要为不断增长的人口提供充足、健康的食物。季节性投入，包括合成农药和化肥，被应用于农作物，以减少病原体造成的损失，并提高农作物生物量，尽管它们的生产和应用也会招致一些经济和环境处罚。因此，迫切需要新的解决方案来提高作物产量，同时减少对这些季节性投入的依赖。土壤微生物产生的挥发性有机化合物（VOC）可以提供替代的、可持续的解决方案，因为它们能够抑制植物病原体，诱导植物对病原体的抵抗力并增强植物的生长促进作用。这篇综述将重点介绍我们对微生物挥发性有机化合物 (mVOC) 生物活性的理解的最新进展，提供将其开发为当前不可持续季节性投入的可行替代品所需的研究观点。这可以确定 mVOC 研究的潜在新途径，并激发学术界和农业企业部门的讨论。
