General Comments

Fungal pest of various bean species and soya. Known to be present in much of the world, where it can cause impacts, but has not been recorded from the UK. Following assessment this pest does not meet criteria for an RNQP in GB due to its absence, but is recommended for regulation as a quarantine pest. A PRA will help to better establish the risk to the UK.
