Subject: Monilia polystroma, a new species of brown rot on Japanese pome fruits

Netherlands researchers declared a new species of brown rot, Monilia polystroma Van Leeuwen, from molecular sequencing of Japanese Monilinia fructigena isolates. Hosts include Malus, Pyrus, Cydonia, and Prunus species. The pathogen survives in mummified fruits. Because Monilia polystroma is biologically very similar to Monilinia fructigena, found in Europe, extra precautions should be taken to prevent the introduction of this new species from Japan. Currently Monilinia fructigena is a regulated pest for the United States.
