Phytophthora tentaculata

Phytophthora tentaculata is a plant pathogen that causes root and stalk rot. It was first isolated in 1993 in a nursery in Germany infecting Chrysanthemum, Verbena and Delphinium ajacis. It has since been found infecting a Verbena in Majorca, Spain in June 2001 but was thought to be restricted to nurseries in Germany and the Netherlands.[1] Other species have since been found to be infected, Santolina chamaecyparissus (Lavender cotton) in Spain in 2004,[2] Gerbera jamesonii in Italy 2006,[3] and Aucklandia lappa in China in 2008.[4]
