| Research Abstract |
Japanese knotweed has become weedy and invasive, and has become seriously problematic in Europe and North America. Therefore, the utilization of the phytophagous insects inhabiting the Japanese knotweed and phytopathgenic fungi living in Japan for development of traditional biological control method was promoted. Based on the results of research provided so far, a field-experiment of Aphalara itadori as a biobontrol agent was started in the UK. However, the expected biocontrol effect is not provided to date, and introduction-plan of Mycosphaerella polygoni-cuspidati(Mp) as second agent is drawn up. In this study, investigation of occurrence situation of leafspot disease caused by Mpin Japan, development of the technique for the artificial inoculation and the molecules chase of Mp, and search of useful endophytic fungi as a helper of biocontrol agent were performed to get the ecological knowledge on the leafspot disease which is next introduction of a biocontrol agent in the UK.
