Popis:	Wintercreeper euonymus (Euonymus fortunei (Turcz.) Hand.-Mazz. ‘Emerald ‘n Gold’) plants were grown in containers on gravel beds that were covered or not covered with black polyethylene sheeting. Half of the beds in each bed treatment were sprayed with a 0.6% sodium hypochlorite (10% bleach) solution immediately after rating plants or performing needed cultural practices such as shearing and weeding (about monthly) to attempt to suppress anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. Plants were rated for disease severity monthly from May through September at one site in 2005 and at two sites in 2006. Presence or absence of polyethylene sheeting or sodium hypochlorite did not affect disease ratings. Disease ratings increased curvilinearly as the growing season progressed. In vitro tests showed that sodium hypochlorite did not inhibit mycelia growth of C. gloeosporioides but eliminated conidial germination.
