Annosus Root Rot

Caused by a fungus infection that enters pines from airborne spores on freshly-cut stump surfaces; attacks and kills all species and ages of Southern pines; fruiting bodies are greyish-brown, bracket-shaped, and vary in size

Leaf Spot

Caused by a fungi that reside in leaf tissue, and whose spores disperse in rain and wind.  Causes small round-to-angular spots onleaf; can be red to rusty-brown to brown and vary in size

Needle Cast

Fungi caused by Lophodermium sp. and Hypoderma sp.; attacks species of conifers and more than 25 fungi exist in the Southeast; first indication is brown or yellowish appearance on needles; spores transported by wind and rain

Nectria Canker

Most common canker to deciduous trees; does not usually kill tree but severely reduces quality and quantity of wood; ridges of callous material form and expand each year

Pitch Canker

Fungus attacks Southern pines;  originates in wounds in the tree; causes sunken cankers that typically secrete pitch; girdle main stem and can kill part or all of tree

Damping-Off Disease

Fungi attacks newly-germinated seedlings at or just below the ground line; common in coniferous tree nurseries; seedling will fall over in beds when stem tissue cells are destroyed

Slime Flux

Affects hardwood trees through existing wounds; caused by bacterial growth in the sap that flows from tree wounds; as bacteria grows, area darkens and a foul odor is produced; results in loss of quality of wood

Rust

Fungus that attacks several species of trees; needs a living host to survive; restricts growth of tree

Heart Rot

Caused by many different species of fungi; appearance of conks on the outside of the trunk or major limb; fungi enters through wounds in the tree

Brown Spot Needle Blight

Needles are encircled with irregular brown spots; needles die; affected most are longleaf pine seedlings

Littleleaf

Affects shortleaf and loblolly pines; needles appear malnourished, decline slowly, and die prematurely; in early stages needle appear yellow and appear shorter than normal; leads to high mortality and growth reduction; occurs in heavy wet soil with poor aeration and low fertility
