Twig Blight

Washington State University has several excellent resources you can access. Contact your local county Extension office or look at the many web resources such as

I suspect the problem is mummy berry, but it could be Botrytis, Phomopsis, or Botryosphaeria. Knowing which one is important for management options. You should consider submitting a sample to the WSU Plant Diagnostic Clinic.
