Main Disease. Oak wilt is caused by the fungus Ceratocystis 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 (French & Stienstra, 1980). Host Range.
To prevent spreading oak wilt, itâs also important to not move oak firewood from trees killed by oak wilt. If infected wood is moved to a different site and new wounding of oaks occurs in this area, sap beetles could transport the disease from the infected firewood and create a new pocket of this lethal disease.
