Oak wilt is a fungal disease that can quickly kill an oak tree. It is caused by the fungus Ceratocystis fagacearum. Symptoms vary by tree species but generally consist of leaf discoloration, wilt, defoliation, and death. The fungus is spread from diseased to healthy trees by insect vectors or via connections between tree roots.

Chemical treatments are available and are mostly preventive as well. Oak wilt is an important disease of oak for timber production and of oak trees in urban areas.

Famous quotes containing the words oak and/or wilt:
“Yet poetry, though the last and finest result, is a natural fruit. As naturally as the oak bears an acorn, and the vine a gourd, man bears a poem, either spoken or done. It is the chief and most memorable success, for history is but a prose narrative of poetic deeds.”
—Henry David Thoreau (1817–1862)
“Constant you are,
But yet a woman, and for secrecy,
No lady closer, for I well believe
Thou wilt not utter what thou dost not know,
And so far will I trust thee, gentle Kate.”
—William Shakespeare (1564–1616)
