Nursery production of Euonymus fortunei: Chemical and cultural practices for controlling anthracnose

Euonymus fortunei (Turcz.) Hand.-Mazz. is a popular landscaping shrub that is extensively produced by commercial nurseries. However, it suffers during production from symptoms of anthracnose caused by the fungus Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. Symptoms include leaf and stem lesions, defoliation and stem dieback. Cultivars tested included 'Emerald 'n Gold', 'Emerald Gaiety' and 'Canadale Gold'. The objectives of this research were to (1) determine the effect of copper sulfate pentahydrate and mancozeb on C. gloeosporioides growing on E. fortunei in production and in vitro and (2) determine the effect of growing plants on plastic or gravel beds with or without periodic sodium hypochlorite treatment on incidence of C. gloeosporioides on E. fortunei.
