Oak wilt - Bretziella fagacearum (previously known as Ceratocystis fagacearum)
Oak wilt is caused by the fungus Bretziella fagacearum which develops in the outer sapwood of the tree. The infected tree reacts by developing tyloses and gums which subsequently restrict the flow of water and nutrients in affected vascular tissues with the result that the tree wilts and subsequently dies.
If you think you have found a plant pest, report it to the Canadian Food Inspection Agency.
