Pest identification and confirmation—Oak
branch dieback
Unlike oak twig blight, which causes dead white or tan leaves in scattered patches throughout the canopy,
oak branch dieback generally occurs in a whole section of the tree while other parts of the plant appear
healthy. Oak twig blight is associated more with wet conditions; oak branch dieback is more prevalent
during and after periods of drought. Both diseases may become more prevalent when trees are stressed from
environmental conditions. |
