栎枯萎病菌检测防控研究进展

栎枯萎病菌是造成栎枯萎病的致病菌,也是我国进境植物检疫性病原菌。该病菌目前主要分布于美国,主要侵染栎属和栗属植物,可造成毁灭性危害。国内对此病菌研究较少,不利于对该病菌的认识和控制。本文对国内外关于栎枯萎病菌的研究进行了总结,重点归纳了栎枯萎病菌的分类学、分布、寄主、症状、形态学和生物学特征、检疫鉴定技术、侵染循环及防治措施等方面的信息。截至目前,该病害的防治工作方面仍面临挑战,扎实开展检疫工作仍然是防控该病菌的最重要手段。为应对栎枯萎病可能对我国林业生产造成的威胁,应加强口岸检疫鉴定、监测、处理工作及开展国内外合作。

Research progress on detection and control of oak wilt caused by Bretziella fagacearum

Bretziella fagacearum, which causes oak wilt, is listed as a quarantined pathogen in China. The pathogen is currently mainly distributed in the United States and mainly infects Quercus spp. and Castanea spp. plants, resulting in devastating diseases. There is scant research on this pathogen in China, which is not conducive to the understanding and control of this pathogen. Here, we review B. fagacearum as the causal agent of oak wilt, particularly focusing on taxonomy, distribution, host, symptoms, and morphological and biological characteristics. Related detection and quarantine information were also included in this study. However, the use of chemicals and other control measures is still in its early stages, and there are challenges regarding the control of oak wilt. This review includes a comprehensive comparison and summary of the applications, possible challenges, and potential improvements for the control of oak wilt. To date, the prevention and control of this disease remain a challenge, and solid quarantine work is considered the most important means of preventing and controlling it. To deal with the threat that oak wilt may pose to biosecurity in China, this paper puts forward relevant suggestions for strengthening quarantine identification, surveillance, treatment, and cooperation.
