Interpretive Summary: Citrus Huanglongbing (HLB), also known as citrus greening, is a highly destructive disease currently threatening citrus production worldwide. HLB was observed in Guangdong of China over a hundred years ago. Researchers and local citrus growers have battled with the disease through research and exercising various control practices. This study reviews the history of HLB in southern China focusing on the Guangdong area. The disease system was analyzed in terms of symptomatology, etiology, and strategies for diagnostics and control. HLB researchers, regulatory agents, and citrus growers will benefit from this information.

Technical Abstract: Citrus Huanglongbing (HLB) is a highly destructive disease currently threatening citrus production worldwide. In China, the disease is exclusively associated with “Candidatus Liberibacter asiaticus” (CLas), a nonculturable proteobacterium. HLB was observed in Guangdong of China over a hundred years ago. Researchers and local citrus growers have dealt with the disease through research and exercising various control practices. Much of the early work was not well-known outside of China. This review aimed to fill in gaps of historical information by reviewing selected literature records. Along the way, the HLB system within southern China was evaluated. Emphases were on comparison of symptomatology, evolution of etiology, control practice, and impacts of using next generation sequencing technology on CLas research and HLB diagnostics.
