Hello, Several fungi can cause needle cast in spruce but the most likely culprit is the Rhizosphaera fungus. I’m attaching an article from the University of Wisconsin Extension office which outlines the way to treat it. https://hort.extension.wisc.edu/articles/rhizosphaera-needle-cast/ Of course if your tree is too large to treat by yourself, i suggest that you contact a certified arborist.
