How is HLB transmitted?
HLB is spread by two methods, the Asian citrus psyllid (ACP) and grafting. The most frequent method is the ACP. The insect has piercing, sucking mouthparts that allow it to acquire and transmit the bacteria to and from the plant phloem, part of the tree’s vascular system.
What causes Huanglongbing?
Huanglongbing is the most destructive disease of citrus worldwide and has recently been introduced to the US. The disease is caused by the phloem-dwelling pathogenic bacterium Candidatus Liberibacter asiaticus, the asian strain. The bacterium is vectored by the Asian Citrus Psyllid (Diaphorina citri).
How do I know if my tree has HLB?
You can tell the difference because leaves that are yellow due to a nutrient deficiency have a similar pattern of yellowing on both sides of the leaf. In contrast, HLB causes blotchy yellow mottling that varies from one side to the other. This appearance is why HLB translates directly to “yellow dragon disease.”
Is there a cure for Huanglongbing?
There is no cure for this disease and all commercial varieties of citrus are susceptible to HLB. In citrus-producing areas with little or no HLB incidence, early detection and removal of infected trees are critical to prevent spread of the disease.

How can HLB be prevented?
HLB can kill a citrus tree in as little as 5 years, and there is no known cure or remedy. All commonly grown citrus varieties are susceptible to the pathogen. The only way to protect trees is to prevent the spread of the HLB pathogen by controlling psyllid populations and destroying any infected trees.
