Sphaeropsis (Diplodia) Blight
Description
This disease is caused by the fungus Sphaeropsis sapinea. The blight occurs on many pines and some other conifers.

Symptoms
The fungus attacks young, healthy, unwounded needles of new candles. However, on stressed evergreens, twigs may be attacked. Since the fungus increases inoculum on old dead cones, trees thirty years and older are more likely to be attacked.
