Rhizosphaera Needle Cast
Rhizosphaera Needle Cast is a disease affecting spruce, some fir species, pine, and some cedars.
Symptoms often appear the next season after the initial infection. It often begins in the lower canopy of the tree where air circulation is slower and this results in moisture staying on the needles for a longer period of time.
A closer look at infested needles will reveal black spots along the needles.
