柑桔黄龙病经用抗菌素树干灌注法治疗轻病树可以恢复健康,疗效一年,重病树仅见少数新梢生长正常,8～12个月后又重现症状;采用抗菌素叶面喷布法治疗,对抑制病情发展有一定作用,但效果差且不持久;采用抗菌素根际浇灌法治疗无效。病接穗用抗菌素浸泡1～2小时,或49℃温热处理,50分钟,疗效颇佳。除土霉素500单位/毫升组有2株福桔苗木发病外,迄今三年未见一株发病。嫁接成活率:大部分处理组为80～90%,金霉素1000单位/毫升组成活率最低,仅0～12.1%,苗木生长较弱且缓慢。热处理组苗生木长较弱。抗菌素各处理组苗木生长正常。
Citrus Huanglongbing by antibiotic trunk perfusion method of treatment of light tree can restore health, curative effect for one year, only a few serious sick tree growth of normal shoots, 8 to 12 months after the recurrence of symptoms; the use of antibiotic foliar spray treatment , To inhibit the progression of the disease have a certain effect, but the effect is poor and not durable; antibiotic rhizosphere irrigation method invalid. Sclerosis with antibiotics soak 1 to 2 hours, or 49 ℃ warm treatment, 50 minutes, the effect is quite good. In addition to oxytetracycline 500 units / ml group 2 Fukao seedlings disease, so far no case of a three-year incidence. Survival rate of grafting: The majority of the treatment group was 80-90%, the chlortetracycline 1000 units / ml composition lowest survival rate, only 0-12.1%, seedling growth is weak and slow. Heat treatment group seedling wood weaker. Antibiotic treatment groups seedlings grow normally.
