为了加强油菜黑胫病的认识,提高防控和检疫意识,控制病害的扩散、流行和危害,保护中国油菜安全生产,促进油菜产业健康发展.笔者通过油菜黑胫病菌的国内外分布状况、经济危害性、入侵可能性、防控难度等方面的分析,结合油菜经济效益、生态效益和社会效益的重要性,参照国际有害生物风险性分析方法对油菜黑胫病危害风险性进行了综合分析评估.结果表明,中国油菜黑胫病(L. maculans )菌风险值为2.59,属特别危险风险等级.病原菌的入侵将会给中国油菜产业带来巨大威胁,应加强油菜籽进口检验检疫,病原菌监测工作,做好病害防治和抗病育种研究.%The study aims to strengthen the understanding of Leptosphaera maculans of rapeseed, improve the prevention and quarantine awareness, control the spread, epidemic and harm of the disease, protect the safe production of rapeseed in China and promote the healthy development of rapeseed industry. By analyzing the distribution, economic harmfulness, invasion possibility and difficulty of prevention and control of L. maculans at home and aboard, and taking into consideration the economic, ecological and social benefits of rapeseed, the authors evaluated the hazard risk of L. maculans with reference to the international pest risk analysis method. The results showed that: the risk value of L. maculans in China was 2.59, belonging to special high risk level. Since the invasion of the pathogen might bring a tremendous threat to the rapeseed production in China, we should take strategies such as import quarantine, inspection of the pathogen and resistance breeding.
