As the environmental and health concerns alert the necessity to move towards a sustainable agriculture system, biological approach using indigenous plant growth-promoting rhizobacteria (PGPR) gains a strong impetus in the field of plant disease control. In this context, the present review article addresses the usage of rhizospheric antagonistic bacteria as a suitable alternative to control tomato fungal diseases namely Fusarium wilt and early blight disease. Biological control has been considered to be an eco-friendly, safe and effective method for disease management. The inherent traits of PGPR to antagonize a pathogen through various mechanisms has been investigated extensively to utilize them as potent biocontrol agents (BCA). Hence, the article provides a detailed account on different biocontrol mechanisms displayed by BCA. It is also suggested that the use of bacterial consortium ensures consistent performance by BCA in field conditions. Likewise, this review also deals with the opportunities and obstacles faced during commercialization of these antagonistic bacteria as biocontrol agents in the market.
随着环境和健康问题凸显了转向可持续农业系统的必要性,利用本土植物促生根际细菌(PGPR)的生物学方法在植物病害控制领域获得了强大动力。在此背景下,本综述文章探讨了根际拮抗细菌作为控制番茄真菌病害(即枯萎病和早疫病)的合适替代方法的应用。生物防治被认为是一种生态友好、安全且有效的病害管理方法。人们广泛研究了PGPR通过各种机制拮抗病原体的内在特性,以将它们用作有效的生物防治剂(BCA)。因此,本文详细阐述了BCA所展示的不同生物防治机制。还建议使用细菌联合体可确保BCA在田间条件下表现稳定。同样,本综述也探讨了这些拮抗细菌作为生物防治剂在市场商业化过程中面临的机遇和障碍。
