Spruce Tree Disease

From your photos it appears your Spruce have Rhizosophaera Needle Cast. It is fungus that readily affects Spruce in the Midwest. If you notice this early there is a treatment that can be applied. It looks as though your tree/s are highly effected. I would recommend you have an arborist from a local tree care company come and take a look at them. http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/spruce-tree-diseases/rhizosphaera-needle-cast/index.html
