Abstract

Biotic stress, including pest attacks, plant diseases caused by pathogenic microbes, and competition from weeds, significantly limit the optimal crop productivity. The use of beneficial microorganisms has been shown to enhance plants' tolerance to these stressors. Numerous laboratory studies have investigated the effectiveness of microbial secondary metabolites as biological control agents against pests, diseases, and weeds. However, a critical challenge remains in determining whether microorganisms applied in the field will produce the same secondary metabolites as those observed in the laboratory, and whether their effectiveness will be comparable, better, or worse. This review examines the comparative effectiveness of microbial agents in producing secondary metabolites that enhance plant tolerance to biotic stress, considering both laboratory and field settings.

生物胁迫（包括害虫侵袭、病原微生物引起的植物病害以及杂草竞争）显著限制了作物的最佳生产力。研究表明，利用有益微生物可增强植物对这些胁迫因子的耐受性。大量实验室研究已证实微生物次生代谢产物作为生防制剂在防治害虫、病害和杂草方面的有效性。然而，当前仍面临一个关键挑战：如何确定田间应用的微生物是否能产生与实验室观察结果相同的次级代谢产物，以及其效果是否与实验室相当、更优或更差。本综述通过比较实验室与田间环境，系统考察了微生物制剂在产生增强植物生物胁迫耐受性的次级代谢产物方面的相对有效性。
