Huanglongbing

Huanglongbing (HLB), or Asian Citrus Greening, is caused by the bacterium Candidatus Liberibacter asiaticus, which is mostly spread by the insect vector Asian Citrus Psyllid (ACP), Diaphorina citri. As a well-publicised example, HLB has destroyed >80% of the US Florida citrus industry, where growers did not strictly follow the best-practice control measures.
