Avoidance of root-infecting microorganisms was originally considered one of the advantages of cultivation of crops in a soilless, recirculating nutrient solution. However, to date, four viral, three bacterial and 21 fungal pathogens have been identified as causal agents of root disease in hydroponically-grown crops. Root-infecting fungi, particularly those which produce a motile stage known as a zoospore, have been the primary pathogens associated with extensive crop losses. Documented sources of these root pathogens in hydroponic systems include peat, surface water such as rivers and streams, and insects. The severity of disease caused by these introduced root pathogens is primarily governed by the genetic susceptibility of each crop and the temperature of the recirculating nutrient solution.
避免根部感染微生物最初被认为是在无土循环营养液中种植作物的优势之一。然而，迄今为止，已鉴定出四种病毒、三种细菌和21种真菌病原体是水培作物根部疾病的致病因子。感染根部的真菌，特别是那些产生游动孢子这一游动阶段的真菌，一直是导致大量作物损失的主要病原体。水培系统中这些根部病原体的记录来源包括泥炭、河流和溪流等地表水以及昆虫。这些引入的根部病原体所引起疾病的严重程度主要取决于每种作物的遗传易感性和循环营养液的温度。
