Diplodia Tip Blight
Sphaeropsis sapinea (formerly Diplodia pinea) (fungus)
A fungal disease primarily affecting pine species, causing tip blight and cankers. Most severe on trees planted outside their natural range and under stress conditions. The disease is rare in normal forest conditions but common in urban environments.

Potential Damage
Lifecycle
Dark brown conidia appear as brown specks at tips of pycnidia under needle sheaths. Spores are splash-dispersed by rain from early spring to late fall, entering needle and bud tissues directly. Lesions grow rapidly into twigs for about 3 weeks during spring bud elongation. Cones become infected and produce copious spores the second year.
Professional Treatment Approach
Fungicide injection for preventive treatment
Remove and destroy infected tips before spore release
Improve growing conditions to reduce stress
Avoid planting susceptible species outside natural range
Maintain proper spacing and drainage
