Sphaeropsis sapinea (fungal pathogen)

Sphaeropsis sapinea is a type of fungus that primarily affects pine trees. It can cause a disease known as "diplodia tip blight," leading to needle browning, stunted growth, and dieback of the tree's tips. This pathogen spreads through spores, particularly in warm, wet conditions. Infected trees can exhibit reduced vigor and may become more susceptible to other pests and diseases. While it primarily impacts forestry and landscaping, managing this fungus involves proper tree care, avoiding overhead watering, and, in some cases, applying fungicides to protect healthy trees from infection.
