Continue Reading to recognize and address common diseases affecting Southern Red Oaks in our region.
Anthracnose (Apiognomonia quercina): Anthracnose is a fungal disease that often impacts Southern Red Oaks during cool, wet springs. Certified arborists should be on the lookout for symptoms such as irregularly shaped brown spots on leaves, wilting, and premature leaf drop. To manage anthracnose, consider fungicidal treatments and preventive measures like proper pruning to improve air circulation.
Powdery Mildew (Microsphaera spp.): Powdery Mildew is a common fungal disease that manifests as a white powdery substance on the leaves. Certified arborists should monitor for distorted leaves and stunted growth. To manage Powdery Mildew, ensure proper spacing between trees for adequate air circulation and consider fungicidal treatments if the infection is severe.
Bacterial Leaf Scorch (Xylella fastidiosa): Bacterial Leaf Scorch is a bacterial disease that affects the xylem vessels of trees, leading to leaf discoloration and wilting. You should observe for browning of leaf margins and interveinal areas. There is no cure for Bacterial Leaf Scorch, but a certified arborist, like Louisiana Tree Pro, can implement preventive measures such as avoiding stress to the tree and managing insect vectors.

Inspect the base of the tree for signs of decay, wilting, and sparse foliage. Implementing proper water management, improving soil drainage, and applying fungicides can aid in preventing and managing root rot.
