› Alabama
Entire state is under quarantine for Asian citrus psyllids.
In order to ship host plants of the Asian citrus psyllid from Alabama, the plant must be treated, inspected and accompanied by a limited permit that prevents distribution to any citrus-producing states or territories where the Asian citrus psyllid is not present.
› California
All of Los Angeles and Orange counties, as well as parts of San Diego, Imperial, and Riverside counties are under quarantine for Asian citrus psyllids.
According to Federal law, host plants cannot be moved from these quarantined areas to the American Samoa, Arizona, the Northern Mariana Islands, the U.S. Virgin Islands, nor to areas of California and South Carolina that have NOT been quarantined because of the presence of Asian citrus psyllid.
In order to ship host plants from locations under quarantine for the Asian citrus psyllid to areas other then those listed above, however, the plant must be treated, inspected and accompanied by a limited permit that prevents distribution to any citrus-producing states or territories where the Asian citrus psyllid is not present.
› Florida
Entire state is under quarantine for citrus greening disease and Asian citrus psyllids.
It is illegal to move live citrus plants, plant parts, budwood, or cuttings from Florida. (Note: Dooryard citrus fruit cannot be moved from Florida unless the fruit is packed at a certified packinghouse and has been issued a Limited Permit by USDA. Florida gift fruit must also come from a certified packinghouse and be shipped under a Limited Permit issued by USDA. In either case, dooryard citrus or gift fruit cannot be shipped to California, Texas, Arizona, Hawaii, Louisiana, American Samoa, Puerto Rico and the U.S. Virgin Islands.)
› Georgia
Entire state is under quarantine for citrus greening disease and Asian citrus psyllids.
It is illegal to move live citrus plants, plant parts, budwood, or cuttings from Georgia.
› Guam
Entire island is under quarantine for Asian citrus psyllids.
In order to ship host plants of the Asian citrus psyllid from Guam, the plant must be treated, inspected and accompanied by a limited permit that prevents distribution to any citrus-producing states or territories where the Asian citrus psyllid is not present.
› Hawaii
Every island is under quarantine for Asian citrus psyllids.

Entire state is also under quarantine for Asian citrus psyllids.
In order to ship host plants of the Asian citrus psyllid from the state (except for Orleans and Washington parishes), the plant must be treated, inspected and accompanied by a limited permit that prevents distribution to any citrus-producing states or territories where the Asian citrus psyllid is not present.
› Mexico
Asian citrus psyllids have been detected in Mexico, including Tijuana city, close to the California border. Although authorities between the U.S. and Mexican governments are working closely to monitor and inspect citrus plants and plant materials, it is advised that no host plants—including all live citrus plants, budwood, and cuttings—be shipped or moved from Mexico to the United States.

› South Carolina
Beaufort and Charleston counties are under quarantine for citrus greening disease. Host plants of citrus greening—including all live plants, budwood, and cuttings—are prohibited from being shipped or moved outside of these counties.
Three counties are also under quarantine for Asian citrus psyllids—Beaufort, Charleston, and Colleton.
According to Federal law, host plants from Colleton County cannot be moved to the American Samoa, Arizona, the Northern Mariana Islands, the U.S. Virgin Islands, nor to areas of California and South Carolina that have NOT been quarantined because of the presence of Asian citrus psyllid. (Currently, the only South Carolina counties where host plants originating from Colleton County can be moved are Beaufort and Charleston.)

Citrus greening is one of the most serious citrus plant diseases in the world. It is also known as Huanglongbing (HLB) or yellow dragon disease. Once a tree is infected, there is no cure. While the disease poses no threat to humans or animals, it has devastated the citrus crops in Asia, Africa, the Arabian Peninsula and Brazil. Citrus greening is now a serious threat to the U.S. citrus industry. Infected trees produce fruit that are green, misshapen and bitter, unsuitable for sale as fresh fruit or for juice. Most infected trees die within a few years.
The Asian Citrus Psyllid
Citrus greening disease is primarily spread by a tiny insect, the Asian citrus psyllid. No bigger than the head of a pin, the infected insect spreads the disease as it feeds on the leaves and stems of citrus trees. Once the Asian citrus psyllid picks up the disease, it carries it for the rest of its life. Citrus greening is then spread by moving infected plant material, such as potted plants, bud wood and even leaves.
The psyllids develop from an egg through five nymphal stages that look similar, but increase in size after each molt.
Symptoms
Citrus plants infected by the citrus greening bacteria may not show symptoms for years and these symptoms can resemble those of other diseases and nutritional deficiencies. Here’s what to look for:
- Blotchy mottling of leaves and leaf yellowing that may appear on a single shoot or branch
- Small, lopsided, and bitter fruit that remains green even when ripe
- Twig dieback
- Stunted, sparsely foliated trees that may bloom off season
In areas of the world affected by citrus greening, the disease has seriously threatened or even wiped out citrus crops. Until a treatment or cure is found, stopping the spread of this deadly disease by halting the movement of plants is our only hope of saving America’s citrus.
