Japanese knotweed has been in the UK since the early 19^<th> Century, but it is only in relatively recent times that the plant has shown itself to be a cost to urban development and a threat to biodiversity. The weed distributed in the UK is one female clonal plant originated in Japan, so species specific to the host hold a great potential to control this weed biologically. The objectives of this study were survey natural enemies, especially phytopathogenic fungi infected to the weed, identification of the collected phytopathogenic fungi, and investigation of possibilities of the potential phytopathogenic fungi as biocontrol agents. Mycosphaerella polygoni-cuspidati was identified as a causal pathogen of leaf spot disease, and evaluated as an effective biocontrol agent. Moreover, many kind of endphytic fungi were isolated from the Japanese native plants. Among these isolates, disease enhanced fungi were detected.

自19世纪初以来，日本虎杖一直在英国<th>，但只是在相对较近的时期，这种植物才显示出自己是城市发展的成本和对生物多样性的威胁。分布在英国的杂草是一种起源于日本的雌性克隆植物，因此对宿主具有特异性的物种具有很大的生物防治潜力。本研究的目的是调查杂草的天敌，特别是植物病原真菌，鉴定收集的植物病原真菌，并探讨潜在的植物病原真菌作为生物防治剂的可能性。经鉴定，尖叶球腔菌（Mycosphaerellaisi-cuspidati）为叶斑病的病原菌，是一种有效的生防菌。此外，还从日本本土植物中分离到多种内生真菌。在这些分离物中，检测到病害增强真菌。
