Peronosclerospora maydis(PRSCMA)

Distribution details in Japan

Situation
Current pest situation evaluated by EPPO on the basis of information dated 2021: Absent, invalid record
From CABI Disease map 510 (1993): Present, no details
Comments
The record appearing in the 1993 version of CABI distribution was based on a misunderstanding of a paper by Hirose and Nojima (1978). This paper was in fact describing experiments on Peronosclerospora maydis conducted in thee eastern part of Java, Indonesia and NOT in Japan. The absence of the pathogen has been confirmed by the NPPO of Japan via correspondance to CABI in 2021.
