柑橘黄龙病药物防治策略

Strategies on drug prevention and control of citrus Huanglongbing

柑橘黄龙病(HLB)是世界范围内柑橘生产上的毁灭性病害,已在全球范围造成了巨大的经济损失。黄龙病由韧皮部限制性寄生菌Candidatus liberibacters spp.引起,主要通过柑橘木虱Diaphorina citri(Kuwayama)在田间传播。目前,黄龙病的主要防治方法有:一是传统的“三板斧”防治策略,即种植无病苗木、严防木虱(大面积连片统防统治)和挖净病树;二是药物防治,主要包括抗生素化学药物、窄谱靶向化学药物、免疫诱导物、纳米制剂等在内的多种抗菌剂。本文对近年来国内外柑橘黄龙病药物防治的相关研究进行了系统论述,以期为柑橘黄龙病菌新型防治药剂研发提供理论依据和参考。

Huanglongbing(HLB)is one of the most devastating disease of citrus worldwide,which has caused huge economic losses.It is caused by phloem-limited bacteria Candidatus liberibacters,and disseminated in orchards by Diaphorina citri(Kuwayama).At present,the main prevention methods of HLB disease are as follows:first,the traditional“three-axes”prevention and controlling strategy,namely,planting pathogen-free citrus,removing the infected plants,and large scale successive killing of psylla;second,drug control,mainly including antibiotic drugs,narrow-spectrum targeted drugs,immune inducers,nano-agents and other antibacterial agents.This review systematically discusses the development on drug control of citrus HLB at home and abroad,hoping to provide theoretical basis and reference for the research and development of new drug for citrus HLB.
