Diplodia Tip Blight of Pine (PPFS-OR-W-21)

Diplodia tip blight is a serious disease of landscape pines in Kentucky, resulting in needle death and dieback. Austrian (Pinus nigra), Scots (P. sylvestris), and Mugo (P. mugo) pines are most commonly affected.  As branch dieback progresses upward in diseased pines, trees may become disfigured and unsightly.  Severe infections that occur during consecutive years weaken and eventually kill affected pines.

This fact sheet covers symptoms, cause, and disease spread.  Recommendations on managing and reducing the risk of tip blight disease are also provided.

Diplodia Tip Blight of Pine (PPFS-OR-W-21) is available online.
