Botryosphaeria Dieback/Canker
Botryosphaeria dothidea
Cankered dogwood stem
Severity: 3.5 out of 5
Frequency: 3 out of 5
Symptoms: Botryosphaeria spp. in general cause cankers that girdle infected branches and stems. The girdling causes foliage to wilt turn brown and die. All plant tissue, from the girdling canker out to the tip, eventually dies.
Cycle: Varies with the species of Botryosphaeria and the host plant.
Management: The pathogen cannot usually attack healthy plants. Control by pruning out the dead and dying tissue, fertilize correctly, and improve growing conditions.
