Oak decline
Trees are weakened by environmental stresses such as drought, waterlogging, frost or by pests such as defoliating or sucking insects. Weakened trees are then invaded and killed by insects and diseases that cannot successfully attack healthy trees. Usually the progression of decline is slow, and it occurs over several years.

Oak wilt
Oak wilt is a lethal disease of oaks, especially species in the red oak group. A fungus invades the tree, which causes it to die. In Missouri, the oak wilt fungus is spread primarily when sap-feeding beetles carry oak wilt spores to fresh wounds during the early part of the growing season.

Rapid white oak mortality
Beginning in August 2011 and continuing through fall 2013, the Missouri Department of Conservation’s Forest Health staff received many reports of rapid white oak decline and mortality, often occurring within one growing season. In 2013, a majority of reports came from east central and southeast Missouri.

Now is the time to look for TCD symptoms
Although not detected in Missouri, TCD could easily get here on infested walnut wood used for woodworking or firewood from western or eastern states where TCD has been confirmed. Late July and early August is the best time to watch for possible symptoms of TCD.
