番茄青枯病发生机制及主要防治技术研究进展

Research Progress on Pathogenic Mechanism and Main Control Techniques of Tomato Bacterial Wilt

番茄青枯病是一种典型的由劳尔氏青枯菌引起的维管束土传病害。该病害的病原菌致病力强,被侵染的宿主死亡率高,发病严重时,可使番茄大面积死亡甚至绝收,造成番茄产量降低,质量下降,严重影响番茄产业的健康发展。本文根据近年来番茄青枯病的研究状况,阐述了番茄青枯病的作用机制、病害症状、发病途径以及主要生物防治方法,并提出目前番茄青枯病研究方面存在的问题以及对该病害的防治进行了展望。

Tomato bacterial wilt is a typical soil-borne vascular disease caused by Ralstonia solanacearum.The pathogen of the disease has strong pathogenicity,and the mortality of the infected host is high.When the disease is serious,it can reduce the yield and quality of tomato,and cause large-scale death or even no yield of tomato,in the end,seriously affects the healthy development of tomato industry.Based on the research status of tomato bacterial wilt in recent years,this paper expounds the pathogenic mechanism,disease symptoms,pathogenesis and main biological control methods of tomato bacterial wilt,and proposes the problems existing in the current research on tomato bacterial wilt,moreover,prospects related research direction of prevention and control of this disease.
