Trees, Shrubs and Conifers: Dead leader on serbian spruce, 1 by pdools_NJ

The tree is about 3 years old and 9 feet tall now in a partially shaded part of the yard. Soil is slightly clay so stays moist, but I wouldn't say wet. Attached is a cross-section of the branch- the length displayed is about 6 inches. Does look like some type of larva was in the middle although it was just mush when I poked it with a toothpick. Would you suggest spraying the tree as a proactive measure or just stick with pruning?

Again, thanks everyone for your input and advice.
