Sphaeropsis blight (Diplodia tip blight) is caused by the fungal pathogen Sphaeropsis sapinea (also known as Diplodia pinea) and the symptoms include browning and stunting of the needles, branch dieback, cankers, and root disease.
Brown, yellow, gray, or straw-colored needles at tip of current season's growth; needles usually stunted and shoot may curl. Branch dieback. Small, black fruiting bodies on needles, cones, or shoot tissue. Cankers on stems or branches. Oozing resin that adheres to blighted needles.
