U.P. Michigan blueberry stem issues
It's been a long, cool and somewhat wet spring here in the U.P. and a local resident brought blueberry stems to our office looking for a diagnosis and information regarding the best way to combat whatever is affecting their blueberries. Plants started looking "funny" last year but are much worse this year. Botryosphaeria Stem Canker or Phomopsis Twig Blight are about the best I could come up with but don't want to misdiagnose so your assistance would be greatly appreciated.
