Aetiology of garlic rot, an emerging disease in France

The incidence of garlic rot has constantly increased in France since the early 2000s. To set up an efficient method protection against this disease, we have clarified its aetiology. This was achieved by surveying from two main French basins production over 3 years. Fungi were isolated 5,493 cloves belonging to pink, purple, and white types. Sequencing translation elongation factor 1α gene 1,171 strains revealed that 94% belonged species Fusarium proliferatum 6% F. oxysporum. pathogenicity both on confirmed artificial inoculations reisolations. There significantly more oxysporum with symptoms coming southeast basin (9.44%) than southwest (2.76%). study confirms is present However, pink type harbours less frequently (1.59%) (9.39%) purple (7.34%) rpb1, rpb2, ITS, IGS regions a subsample there little genetic diversity population proliferatum.
