Marguerite daisy (Argyranthemum frutescens) is an ornamental plant, that is used as a potted and landscape plant. In 2006, disease symptoms were observed on marguerite daisy (A. frutescens cv. 'Butterfly') in greenhouses in Brno-Tuřany. The pathogen primarily affected newly expanded young leaves and shoot tips. They were chlorotic, twisted and stunted. The affected leaf tips were necrotic. Bud flowers and flowers were deformed and get dry. The extensive purplish brown growth of downy mildew colonized the lower surface of infected leaves. Older leaves were unaffected.
