The agriculture is extremely important for the life of human beings. Therefore, it is needed to control the enemies that destroy vast areas of crops causing great economic losses. Chemical pesticides were the option for many decades, but the damage that they cause to environment and human health led to the idea of changing the use of these for more sustainable options such as biopesticides as a biological control. Among microbial pesticides, Serratia species have been found as suitable options to apply against several pests or pathogens. Serratia species produce a wide range of secondary metabolites with several biological activities such as antifungal, antibacterial, and pesticides which can be used in sustainable agriculture. It has been reported that several Serratia species are able to suppress some crop diseases caused by Fusarium oxysporum, Rhizoctonia solani, Phytophthora parasitica, Sclerotinia sclerotiorum, Verticillium dahlia, and Phytophthora capsici among others. Therefore, they have been used as biocontrol agents in agriculture. In this review, we summarized the genus Serratia describing its history and development and the metabolites it secretes, which are responsible for their antibacterial and antifungal activity. We have analyzed the insecticide capacity of several Serratia species as well antifungal properties of Serratia species against most important crops' pathogens. In conclusion, the use of Serratia as a biological control agent against plant pathogens can be a good option for a sustainable agriculture. More work is needed to assess the safety of the isolated new strains and their effectiveness against pathogens in in vivo conditions.
农业对人类的生活极其重要。因此，需要控制那些破坏大片庄稼、造成巨大经济损失的害虫。几十年来，化学农药一直是人们的选择，但它们对环境和人类健康造成的损害促使人们想到改变使用方法，选择更可持续的选项，如生物农药作为生物防治。在微生物农药中，发现沙雷氏菌属的某些物种是对抗几种害虫或病原体的合适选择。沙雷氏菌属产生广泛的次生代谢物，具有多种生物活性，如抗真菌、抗菌和杀虫剂，可用于可持续农业。据报道，几种沙雷氏菌属能够抑制由尖孢镰刀菌、立枯丝核菌、寄生疫霉、核盘菌、黄萎轮枝菌和辣椒疫霉等引起的一些作物病害。因此，它们被用作农业中的生物防治剂。在这篇综述中，我们总结了沙雷氏菌属，描述了它的历史和发展以及它分泌的代谢物，这些代谢物是其具有抗菌和抗真菌活性的原因。我们分析了几种沙雷氏菌属的杀虫剂能力以及沙雷氏菌属对大多数重要作物病原体的抗真菌特性。总之，将沙雷氏菌属作为防治植物病原体的生物防治剂可能是可持续农业的一个不错选择。需要更多的工作来评估分离的新菌株的安全性及其在体内条件下对病原体的有效性。
