柑桔黄龙病是我国南方柑桔产区的危险性病害,它可通过苗木接穗和柑桔木虱传播。建国以来,柑桔黄龙病病原的探讨、生态条件与发病关系以及防治措施等研究工作都取得很大进展。目前虽然对病原问题尚未取得一致认识。但对培育无病苗发展新区、改造老病区和实施苗木检疫是发展柑桔生产当务之急的看法已渐趋一致。林孔湘等于1956～1966年试验:柑
Citrus Huanglongbing is a dangerous disease in southern citrus producing areas of our country. It can be transmitted through seedling scion and citrus psyllid. Since the founding of the People’s Republic of China, great progress has been made in the research on the pathogen of citrus Huanglongbing, the relationship between ecological conditions and disease and the prevention and treatment measures. Although at present there is no consensus on the pathogen. However, the idea of developing a new zone for developing disease-free seedlings, reforming old ward areas and implementing seedling quarantine is a top priority for developing citrus production.
