Korean Snow Pear Dieback: Fire Blight or Natural Aging

Branches dying from tips, progressing. Started last year. Other limbs okay.

Possibilities

Fire blight: Sudden blackening, scorched look. Prune dead, clean debris, spray preventive (best before symptoms).
Borers: Holes circling branches, sap ooze. Spray borer spray.
Natural dieback: Common in older pear trees; prune dead, seal with paint, tree recovers.

Recent bad fire blight years suggest that. Prune dead, seal, monitor.
