I have confirmed from our local Water and soil conservation district that Cytospora Canker is on our blue spruce …after cutting down dead branches, Is there a fungicide that you can recommend to treat the tree?
Becker County Minnesota
Expert Response
Sadly there is no cure, it can be managed with practices that strengthen the tree and fungal sprays don’t really help.
