Citrus Greening (Huanglongbing, HLB)

Huanglongbing (also known as HLB or citrus greening) is a disease affecting citrus production all over the globe. Citrus greening affects all citrus cultivars and causes tree decline, a serious threat to Florida's citrus industry. The disease is believed to be caused by the bacterium Candidatus Liberibacter asiaticus. The Asian citrus psyllid transmits the bacterium and is found throughout Florida.
