Erwinia amylovora(ERWIAM)
Distribution details in Japan (Hokkaido)
Current pest situation evaluated by EPPO on the basis of information dated
2010: Absent, unreliable record
Bacterial shoot blight occurs on Asian pear (EPPO Reporting Service (1996/108) ). This fireblight-like disease only occurs on Hokkaido and not on the other islands. It has been suggested that it is caused by E. amylovora. In 1992, the NPPO of Japan had denied the presence of fire blight.
According to Thapa et al. (2010), Japanese Erwinia isolates (from pears in Hokkaido) are more closely related to E. pyrifoliae than to E. amylovora. It is sugggested that they belong to the species E. pyrifoliae or possibly to a new Erwinia species.
