First report of Turnip crinkle virus infecting garlic mustard (Alliaria petiolata) in Germany.
In May 2018, three samples of wild garlic mustard (Alliaria petiolata) were collected from a private garden in Koenigslutter, Germany. While sample EPV_18_002 was asymptomatic apart from slight yellowing, samples EPV_18_003 and EPV_18_004 showed stunting, yellowing, necrosis and severe crinkling. The causal pathogen was isolated and identified as Turnip crinkle virus (TCV) based on molecular and pathogenicity analyses. This is thought to be the first report of a TCV strain from Germany occurring on garlic mustard.
