Common Tree Pests and Diseases

With massive limbs and deep roots, trees can give the impression that they’re impervious – invincible, even – but this simply isn’t true. Despite their immense strength, trees can fall victim to a range of pests and diseases. These can lead to a variety of issues, including the death of the tree. Since early detection and intervention is the best defense, we’ve put together this information on common tree pests and diseases in the Southeast – and what you can do if you think you’re dealing with them.

Follow along as we discuss the risks and treatments of common tree pests and disease threats here in the southeastern United States.

Watch Out for These Tree Pests and Diseases

Unfortunately, the threats to your trees have been rapidly increasing in recent years. Pests and diseases that used to be found only in certain parts of the country have migrated here. Catching pests and tree maladies early will help preserve your trees and keep them healthy.

Here are some common pests and tree diseases you should be aware of in the Athens GA, Atlanta GA, and Nashville TN areas:

• Southern Pine Beetle (Dendroctonus frontalis): This destructive insect targets pine trees, particularly stressed or weakened ones. Infestations can lead to widespread pine mortality, impacting forest ecosystems and the timber industry in the Southeast.
• Dogwood Anthracnose (Discula destructiva): Dogwood trees in the Southeast are susceptible to anthracnose, a fungal disease causing leaf spots, stem cankers, and dieback. Severe infections can result in defoliation and the decline of these iconic trees in the region.
• Emerald Ash Borer (Agrilus planipennis): Infesting ash trees, the emerald ash borer is an invasive beetle that disrupts nutrient flow, causing canopy dieback and eventual tree death. The presence of this pest poses a significant threat to ash tree populations in the Southeast.
• Oak Wilt (Ceratocystis fagacearum): Oak wilt is a vascular disease affecting various oak species in the Southeast. It spreads through root grafts and insect vectors, causing leaf discoloration, wilt, and death. The disease poses a risk to both urban and natural oak forests.
• Pecan Scab (Venturia effusa): Pecan trees in the Southeast are susceptible to pecan scab, a fungal disease affecting leaves, nuts, and twigs. Severe infections can lead to defoliation and reduce nut quality, impacting the region’s pecan industry and orchards.
