What Is Oak Wilt?
Oak Wilt is a deadly fungal disease caused by the pathogen Bretziella fagacearum. It affects oak trees and spreads through root grafts and insect carriers, particularly sap-feeding beetles. Once infected, oak trees can succumb to the disease quickly, often within a single growing season, making early detection and management critical.
How Does Oak Wilt Spread?
Oak Wilt spreads in two primary ways:
1. Root Grafts: Oak trees growing close together can develop interconnected root systems, allowing the fungus to pass from an infected tree to a healthy one.
2.
Insect Vectors: Beetles are attracted to sap from freshly pruned or wounded oak trees and carry the fungal spores to healthy trees.
What Are the Symptoms of Oak Wilt?
Recognizing the signs of Oak Wilt early can help mitigate its spread. Common symptoms include:
Wilting Leaves: Leaves begin to brown from the edges inward, often curling and falling prematurely.
Discoloration: Leaves may turn dull green, bronze, or tan before wilting.
Rapid Leaf Drop: Affected trees may lose many leaves quickly.
Dark Streaks in Wood: When the bark is removed, dark streaks may be visible in the tree’s vascular system.
Crown Dieback: The upper canopy may show thinning or complete dieback.
Is Oak Wilt Deadly?
Yes, Oak Wilt is often fatal, particularly for red oaks. Once infected, red oaks can die within weeks, while white oaks may decline more slowly. The disease can spread rapidly through neighborhoods or forests without intervention, devastating oak populations.
