火龙果腐烂病是一种对我国新兴的火龙果果业潜在风险较高的真菌病害。近年来,我国口岸多次从越南进口的火龙果鲜果中截获该病害。本文介绍了其病原真菌仙人掌平脐蠕孢(Bipolaris cactivora(Petrak)Alcorn)地理分布、寄主范围、经济危害性、症状及病原菌形态特征、形态学鉴定和分子检测方法 ;分析了病原菌的进入风险和定殖与扩散风险,提出了加强口岸植物检疫,严防病原菌传入及病害在国内发生扩散和蔓延等风险管理措施。
Dragon fruit rot disease is a fungus disease that is potentially high risk to our country’s emerging pitaya fruit industry. In recent years, many of the fruits of dragon fruit imported from Vietnam at the ports of China have intercepted this disease. In this paper, the geographical distribution, host range, economic hazard, symptoms and morphological characteristics of pathogenic bacteria, morphological identification and molecular detection of its pathogenic fungi, Bipolaris cactivora (Petrak) Alcorn were introduced. The risk of entry of pathogens and Colonization and proliferation risk, put forward to strengthen the port phytosanitary, to prevent the introduction of pathogens and disease spread in the country and other risk management measures.
