Deadly citrus greening disease is on the move.

Named for its green, misshapen fruit, citrus greening disease has destroyed millions of acres of citrus plants around the world. It is spread by a disease-infected insect, the Asian citrus psyllid, and has put the future of America’s citrus at risk. Help stop the spread of this deadly plant disease. Don’t risk citrus. Don’t move citrus plants.

Charleston County is 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 the county

Three counties are under quarantine for Asian citrus psyllids.

In order to ship host plants of the Asian citrus psyllid from the following counties, 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:
Beaufort
Colleton

Citrus greening disease has spread throughout the state of Florida and has been found in Louisiana.
The entire state of Florida is now under quarantine.
Asian citrus psyllids have also been found in Mexico, southern California and other citrus-producing states.

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.
