EFSA Scientific Opinion on Pest risk assessment made by France on Mycosphaerella eumusae considered by France for French Guiana, Guadeloupe, Martinique and Réunion
This document presents the opinion of the Panel on Plant Health on the simplified pest risk assessment conducted by France on Mycosphaerella eumusae with Guadeloupe and Martinique considered as endangered area.
Three related fungal species within the genus Mycosphaerella induce important leaf spot diseases on Musa spp.: Mycosphaerella eumusae, M. musicola and M. fijiensis are responsible for eumusae leaf spot disease, Sigatoka leaf spot disease and black leaf streak disease, respectively.
M .fijiensis and M. musicola are known to cause serious economic damage on banana. M. eumusae is a recently described species and was first detected in a survey carried out in 1992-1995 in south and south-east Asia to determine the distribution of M. fijiensis and M. musicola. The pathogen has now been found in India, Malaysia, Mauritius, Nigeria, Réunion, Sri Lanka, Thailand and Vietnam, but its distribution may be greater than currently reported because of similarities of symptoms with the other Mycosphaerella leaf spot diseases.
M. eumusae is not known to be present in the PRA area of Guadeloupe and Martinique
