Euonymus ground cover

Disease	Symptoms	Pathogen/Cause	Management
Anthracnose	Small spots pepper the leaves of evergreen euonymus. An orange brown, slightly raised stem canker may develop and cause branch dieback.	Glomerella cingulata (asexual stage is Colletotrichum gloeosporiodes)	Avoid overhead watering in the nursery and landscape. Inspect containerized plants and do not use those already infected. Apply a fungicide to protect healthy leaves.
Crown gall	Galls 1/4 inch to several inches in diameter form on stems or roots. These are white at first and firm like cauliflower, but they become hard and dark brown with age.	Agrobacterium tumefaciens carrying a gall-causing plasmid	Purchase gall-free plants. Never plant galled material. Plants not severely affected should be cared for well so that they are not under other stresses. Severely affected plants should be removed. Do not replace the plant with gall-susceptible woody or herbaceous plants. Dip cuttings in Agrobacterium radiobacter, a biological control agent.
