TCD Symptoms
Symptoms of thousand cankers disease resemble drought stress, which causes this disease to often go undetected. One of the first symptoms of this disease is flagging – one or more branches with yellow foliage. Other symptoms include wilting, clinging foliage, limb and/or canopy dieback, and profusion of epicormic shoots (i.e., water sprouts) near the base of the trunk.
