| Research Abstract |
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.
