Plants are exposed to different environmental stresses (biotic or abiotic) in their habitats, these stresses often result in several diseases and decline in crop production which are major concerns to crop producers and scientists. Habitat‐imposed biotic stress is one of the most common problems of crop production. The use of chemical‐based pesticides has been widely reported to control plant diseases but the residual effects of excessive application of pesticides necessitates the use of biological control agents known to play important safety roles in plant disease management. Symbiotic associations between diverse microorganisms and plant roots have also been proven to have enormous impacts on their respective growths and survival; induced systemic resistance (ISR) is part of the mechanism through which plant‐growth‐promoting bacteria and fungi stimulate plant growth and resistance to pathogens. Many of these microorganisms act as stimulants which can be exploited for boosting nutrient uptake, pest control and to protect crops from environmental stresses for better growth. This review focuses on the plant diseases, microbial stimulants and their mechanisms as nutrient enhancers in crop production as well as their potentials in biological control of plant diseases through ISR.

在植物病害管理中诱导系统抗性的微生物刺激剂的探索

植物在其生境中暴露于不同的环境胁迫（生物或非生物），这些胁迫通常导致多种疾病和农作物减产，这是农作物生产者和科学家关注的主要问题。生境施加的生物胁迫是农作物生产中最常见的问题之一。广泛报道了使用化学农药控制植物病害的方法，但是过量使用农药会产生残留效应，因此必须使用已知在植物疾病管理中起重要安全作用的生物防治剂。多种微生物与植物根系之间的共生联系也被证明对其各自的生长和存活产生巨大影响。诱导的系统抗性（ISR）是促进植物生长的细菌和真菌刺激植物生长和抵抗病原体的机制的一部分。这些微生物中有许多可作为刺激物，可用于促进养分吸收，害虫防治以及保护农作物免受环境压力，以实现更好的生长。这篇综述着重于植物病害，微生物刺激物及其在作物生产中作为营养增强剂的机理，以及它们在通过ISR生物防治植物病害中的潜力。
