among 1175 isolates collected from 6 prefectures of Kyushu in 2002 and 2003, 647 are resistant to MBI-D fungicides (inhibitors of melanin biosynthesis), each due to a single point mutation of the scytalone dehydratase gene. Isolates possessing the mutation in the scytalone dehydratase gene would have been selected and then multiplied rapidly in each region of Kyushu as a result of the wide-spread introduction of MBI-D fungicides in a short period
