Huanglongbing (HLB) is the most severe bacterial disease of citrus crops caused by Liberibacter spp. It causes a reduction in fruit yield, poor fruit quality, and even plants death. Due to the lack of effective medicine, HLB is also called citrus "AIDS." Currently, it is essential for the prevention and control of HLB to use antibiotics and pesticides while reducing the spread of HLB by cultivating pathogen-free seedlings, removing disease trees, and killing Asian citrus psyllid (ACP). New compounds [e.g., antimicrobial peptides (AMPs) and nanoemulsions] with higher effectiveness and less toxicity were also found and they have made significant achievements. However, further evaluation is required before these new antimicrobial agents can be used commercially. In this review, we mainly introduced the current strategies from the aspects of physical, chemical, and biological and discussed their environmental impacts. We also proposed a green and ecological strategy for controlling HLB basing on the existing methods and previous research results.
黄龙病（HLB）是由韧皮部杆菌属引起的柑橘类作物最严重的细菌性病害。它会导致果实产量下降、果实品质不佳，甚至植株死亡。由于缺乏有效的药物，HLB也被称为柑橘“艾滋病”。目前，通过培育无病苗木、清除病树以及杀灭亚洲柑橘木虱（ACP）来减少HLB传播的同时，使用抗生素和杀虫剂对于HLB的防控至关重要。还发现了具有更高效力和更低毒性的新化合物[如抗菌肽（AMPs）和纳米乳剂]，并且它们已经取得了显著成果。然而，在这些新型抗菌剂能够商业化使用之前，还需要进一步评估。在本综述中，我们主要从物理、化学和生物学方面介绍了当前的策略，并讨论了它们对环境的影响。我们还基于现有方法和先前的研究结果，提出了一种控制HLB的绿色生态策略。
