The Tennessee Department of Agriculture (TDA) is advising forest landowners to monitor their sassafras trees after detecting new cases of laurel wilt disease in Robertson and Hamblen Counties. In the last quarter of 2019, the disease was detected in trees in Montgomery, Cheatham, Dickson and Williamson Counties. "These new detections of this invasive disease show a significant geographic jump across the state," State Forester David Arnold said. "This is yet another unfortunate example of an invasive pest impacting our forests. Landowners should take caution to prevent the spread of this disease if detected on their property."

Laurel wilt is a fungal disease caused by an invasive pathogen, Raffaelea lauricola, which can affect a range of plants, including sassafras and spicebush in Tennessee. Choked of water, trees wilt and die within a few weeks or months. Currently, no treatment has been developed that can cure laurel wilt disease or protect trees from infection. The best way to prevent the spread of laurel wilt is to avoid movement of firewood or other untreated timber. Tennesseans are urged to monitor their sassafras trees for browning of leaves, leaf loss, and staining in the inner bark. If you suspect your trees might have laurel wilt disease, contact Forest Health Program Specialist Sam Gildiner at 615-837-5439 or sam.gildiner@tn.gov. TDA Division of Forestry staff will assist in identifying the disease and recommending management actions, if appropriate.

Three Tennessee counties have been quarantined for Emerald Ash Borer (EAB) after detection of the forest-devastating insect, bringing the total number of Tennessee counties under a state and federal EAB quarantine to 62. Cheatham, Giles, and Maury counties have been added to the list of areas restricted for the movement of firewood, ash nursery stock, ash timber, and other material that can spread EAB. The tree-killing beetle was recently found in these three counties through the United States Department of Agriculture’s EAB detection program.

Outreach and education is the most effective way to combat the spread of aquatic invasive species. The more people are made aware of the necessity of cleaning and drying boating and fishing equipment before using it in another waterbody, the less likely the aquatic invasive species will be spread to new waters.

A plant disease that presents a serious threat to the U.S. citrus industry has been detected in Alabama. Federal and state plant health officials have confirmed the identification of citrus greening (CG), also known as Huanglongbing or HLB, which is caused by the bacterial pathogen Candidatus Liberibacter asiaticus. This is the first confirmation of citrus greening in Alabama despite biannual surveys for the pathogen by the Alabama Department of Agriculture and Industries (ADAI).

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today confirmed that spotted lanternfly (SLF), an invasive pest from Asia, has been found in Albany and Yates counties. A single adult insect was discovered in a vehicle in the Capital District. In addition, a single adult insect was reported on a private Keuka Lake property in Penn Yan, Yates County. Anyone that suspects they have found SLF is encouraged to send a photo to spottedlanternfly@dec.ny.gov. Please note the location of where the insect was found, egg masses, and/or infestation signs. DEC and DAM also encourage the public to inspect outdoor items such as vehicles, furniture, and firewood for egg masses. Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.
