CG is caused by the bacterium Candidatus Liberibacter asiaticus, which is vectored by an insect, the Asian citrus psyllid (ACP). This disease has been reported in several southeastern US states since 2005 and was confirmed in Texas on January 2012. CG is also found in Asia, Africa, the Arab peninsula, South and Central America, and the Caribbean.
There is no cure for CG, but it can be eradicated if detected early. The best ways to ensure that the disease does not infect trees in Texas are prevention and early intervention. No one should bring in citrus plants from states where the disease and/or ACP have been detected. (For quarantine information, visit saveourcitrus.org.) Look for symptoms, inspect citrus trees often, and report any symptoms you see to the Texas Department of Agriculture (512-463-7476; or toll free, 800-835-5832).
