Sphaeropsis blight

Sphaeropsis blight is a disease that affects pines worldwide. This disease was previously known as Diplodia tip blight. Sphaeropsis blight is considered to be a "disfiguring disease" that attacks pine trees that are growing under stressful conditions. Sphaeropsis blight does not typically kill the tree, but will significantly disfigure the tree if not properly cared for or controlled. Most commonly, Sphaeropsis blight attacks Austrian (Pinus nigra), Scotch (P. sylvestris), and red (P. resinosa) pine trees. This disease is a problem in the United States, nationwide, from coast to coast, and can be found worldwide.
