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 Delaware Department of Agriculture (DDA) announced today that they expanded the spotted lanternfly quarantine to include all portions of New Castle County north of the Chesapeake and Delaware Canal. This is due to recent detections of established populations outside of the initial quarantine zone enacted in February 2019 that included eleven zip codes. "This expansion is necessary in our attempt to eradicate, control, and prevent the spread of spotted lanternfly in Delaware and to surrounding states," said Secretary of Agriculture Michael T. Scuse. The spotted lanternfly is a destructive invasive plant hopper that attacks many hosts including trees, shrubs, orchards, grapes, and hops. For more detailed information regarding the quarantine, permitting, treatment, or to report a sighting of spotted lanternfly, visit the Delaware Department of Agriculture’s dedicated spotted lanternfly webpage at https://de.gov/hitchhikerbug or call the dedicated spotted lanternfly hotline at (302) 698-4632.

The emerald ash borer (EAB), Agrilus planipennis, is an exotic insect pest from Asia. The flattened, creamy white larval stage feeds below the bark and cuts off the living, water and nutrient conducting vessels causing tree death. EAB has been found in 13 Iowa counties (Allamakee, Black Hawk, Boone, Bremer, Cedar, Des Moines, Henry, Jasper, Jefferson, Muscatine, Story, Union, and Wapello). As of February 2014, all 99 counties in Iowa have been quarantined (Treatment Map) by the Iowa Department of Agriculture and Land Stewardship to slow the movement of this destructive pest to non-quarantined areas/states.

Emerald ash borer (EAB), a destructive insect from Asia that attacks and kills ash trees, has been confirmed at two new sites in Delaware: one near Middletown, New Castle County, and another near Seaford, Sussex County. Originally found in northern Delaware in 2016, the new detections create added urgency for homeowners and municipalities to determine if they have ash trees on their property and decide on possible management options. Current guidelines recommend the removal or treatment of ash trees if located within 15 miles of a known infestation. Because Delaware is geographically small and EAB can go undetected for years, residents are urged to educate themselves now and take action.
