Georgia has been put under a federal quarantine to help prevent the spread of a devastating citrus disease. The quarantine follows the discovery in Georgia of "citrus greening" (CG), a disease that causes citrus fruit to be bitter and unusable. The disease is also known as Huanglongbing or HLB and is caused by the bacterial pathogen Candidatus Liberibacter asiaticus. The disease was found on a lemon tree in Savannah. More details can be found at the Georgia Department of Agriculture and USDA APHIS Plant Protection and Quarrentine.

Florida Cogongrass Cost-Share Program
The initial focus of the program is to impede the spread of cogongrass (Imperata cylindrica), one of the world’s worst weeds, from Florida into Georgia. Therefore the nine counties sharing borders with Georgia - Baker, Columbia, Gadsden, Hamilton, Jackson, Jefferson, Leon, Madison, and Nassau - will be the first priority. If funding allows, the program may be expanded to include Wakulla, Suwannee, Union, Washington, Calhoun, Liberty, Clay, Duval, Bradford, Holmes and Taylor counties.

Soybean Rust and Kudzu: An invasive species tag team
For the first time, soybean rust (Phakopsora pachyrhizi) has been documented as overwintering on kudzu (Pueraria montana) without any break in detection in Alabama, Georgia and Louisiana. Scientists are still exploring what the full effect of this may be, but it is possible for infected kudzu in these areas to act as a primary source for the disease.
For more information, take a look at the full story in The Gleaner. For the latest information on the distribution and spread of soybean rust, see the Soybean Rust ipmPIPE.
