The use of and research on medical cannabis (MC) is becoming more common, yet there are still many challenges regarding plant diseases of this crop. For example, there is a lack of formal and professional knowledge regarding fungi that infect MC plants, and practical and effective methods for managing the casual agents of disease are limited. The purpose of this study was to identify foliar, stem, and soilborne pathogens affecting MC under commercial cultivation in Israel. The predominant major foliage pathogens were identified as and , while the common stem and soilborne pathogens were identified as and . Other important fungi that were isolated from foliage were those producing various mycotoxins that can directly harm patients, such as spp. and spp. The sampling and characterization of potential pathogenic fungi were conducted from infected MC plant parts that exhibited various disease symptoms. Koch postulates were conducted by inoculating healthy MC tissues and intact plants with fungi isolated from infected commercially cultivated symptomatic plants. In this study, we report on the major and most common plant pathogens of MC found in Israel, and determine the seasonal outbreak of each fungus.
医用大麻（MC）的使用和研究正变得越来越普遍，但这种作物的植物病害仍存在许多挑战。例如，对于感染MC植物的真菌，缺乏正式的专业知识，且管理病害病原体的实用有效方法有限。本研究的目的是确定在以色列商业种植条件下影响MC的叶部、茎部和土传病原体。主要的叶部病原体被鉴定为[具体病原体1]和[具体病原体2]，而常见的茎部和土传病原体被鉴定为[具体病原体3]和[具体病原体4]。从叶部分离出的其他重要真菌是那些产生各种可直接危害患者的霉菌毒素的真菌，如[具体真菌1]属和[具体真菌2]属。潜在致病真菌的采样和鉴定是从表现出各种病害症状的受感染MC植物部位进行的。通过用从受感染的商业种植有症状植物中分离出的真菌接种健康的MC组织和完整植株来进行柯赫氏法则验证。在本研究中，我们报告了在以色列发现的MC的主要和最常见植物病原体，并确定了每种真菌的季节性爆发情况。
