First report of necrotic streaking of Asiatic lilies caused by Plantago asiatica mosaic virus in Chile.
In Quillota, Chile, a survey was done during the spring of 2015 on greenhouse Asiatic hybrid lilies being grown for cut flowers. Symptomatic plants of the cultivars Amsterdam, Indian Summerset, Litouwen and Serengeti were found. Symptoms consisted of brown necrotic streaking associated with irregular leaf chlorosis and severely infected plants also showed brown streaks in the stem and irregular necrosis in tepal tips. The causal pathogen was identified as Plantago asiatica mosaic virus (PlAMV) based on molecular and pathogenicity analyses. This is thought to be the first report of Koch's postulates for PlAMV on Lilium plants worldwide and the first report of necrotic streaking of lily caused by PlAMV in Chile affecting Asiatic cultivars.
