Thousand Cankers Disease Poses Threat to Pahokee Walnut Trees

Pahokee residents are advised to be vigilant regarding the potential threat of Thousand Cankers Disease (TCD) to local walnut trees. While not yet confirmed in the immediate Pahokee area, this aggressive disease, caused by a fungus carried by the walnut twig beetle, has been identified in other parts of Florida and poses a significant risk to native walnut populations.

TCD primarily affects black walnut trees, which are present in various residential yards and natural areas around Pahokee, including those near the shores of Lake Okeechobee. The disease manifests as numerous small cankers that eventually girdle branches and the main trunk, leading to tree death within a few years of infection. Early signs include yellowing leaves, thinning canopies, and branch dieback.

Local arborists and agricultural extension offices are encouraging property owners to inspect their walnut trees for any unusual symptoms. If residents suspect their trees may be infected, they should contact the Palm Beach County Cooperative Extension Service for guidance on identification and management strategies. Early detection is crucial in mitigating the spread of this destructive disease and protecting Pahokee's valuable tree canopy.
