Citrus Pest & Disease Prevention Program
California Department of Food & Agriculture (CDFA)
Information on Citrus Disease - "Huanglongbing" (HLB) (pronounced Wong-Long-Bing) is a devastating plant disease threatening citrus trees in Southern California, including the San Bernardino area where citrus trees are found in abundance on small farms and at homes.
- Kills citrus trees
- No cure
- NOT harmful to humans or animals
- Has a latency period of 2 - 5 years
- If you think that your tree may be infected with HLB, you may simply call 800-491-1899. In response, a representative of the CDFA will return your call and ask a few questions to determine if your tree should be tested.
- If the CDFA believes that the tree may be infected, they will send out an inspector to take a sample from the tree for laboratory testing to see if it tests positive for the disease.
- If your tree is found to be infected with Huanglongbing (HLB), the CDFA will remove the tree at no cost.
