Erwinia amylovora(ERWIAM)
Distribution details in Japan
Current pest situation evaluated by EPPO on the basis of information dated
2010: Absent, unreliable record
From NPPO: Absent, confirmed by survey
FAO Plant Protection Bulletin 22 (2) indicates that an earlier unconfirmed record is in fact erroneous. From country itself (1993): absent.
EPPO Reporting Service (1996/108) refers to a recent publication of Beer et al. in 7th International Workshop on fireblight at St Catherines, Ontario (CA) showing that bacteria causing "bacterial shoot blight" on Asian pear in Hokkaido seem to be identical with E. amylovora.
According to Thapa et al. (2010), Japanese Erwinia isolates (from Asian pears in Hokkaido) are more closely related to E. pyrifoliae than to E. amylovora. It is suggested that they belong to the species E. pyrifoliae or possibly to a new Erwinia species. According to Mizuno et al. (2010), the Erwinia isolates found on European pears in Yamagata Prefecture (the disease was subsequently eradicated) were distinct from E. amylovora and E. pyrifoliae.
