对柑桔溃疡病苗化学治疗试验结果指出:病苗在1000～2000单位/毫升链霉素+1:100酒精的混合药液中浸1～3小时,便能把病苗治好。处理过的果苗,生长仍然良好。病苗在1:1000～1500的升汞水+1:100酒精的混合药液中1～3小时,也有同样的治疗效果,但苗木生长略差,死亡率略高。用链霉素、升汞水或波尔多液喷射经剪掉病枝叶,或不剪掉病枝叶的病苗,均不能把病苗完全肃清。对柑桔溃疡病的防治,许多国家(如南非、美国等),认为只有毁灭病株,才有可能彻底消灭病原。有时病菌能潜伏数年,如南非有一果园在1918年毁灭病株,1924年重种,当年又发生病害。因此,毁灭病株后,需要连续数年检查,证实无病,才能复种。
The results of the chemical treatment test on the citrus canker disease vaccine indicate that the vaccine can be cured by soaking the mixed vaccine solution of 1000-2000 units / ml streptomycin + 1: 100 alcohol for 1-3 hours. Processed seedlings, growth is still good. Disease vaccine in 1: 1000 ~ 1500 mercuric chloride water +1: 100 alcohol mixed solution 1 to 3 hours, also have the same treatment effect, but slightly worse growth of seedlings, the mortality rate is slightly higher. With streptomycin, mercuric chloride or Bordeaux mixture jet off diseased branches, or do not cut off diseased branches and leaves of disease, can not completely eliminate the vaccine. Citrus canker disease prevention and control, many countries (such as South Africa, the United States, etc.), that only the destruction of diseased plants, it is possible to eliminate pathogens. Sometimes the germs can lurk for years, such as an orchard in South Africa that destroyed the diseased strains in 1918 and re-grown in 1924, when the disease took place again. Therefore, the destruction of diseased strains, the need for several consecutive years of examination, confirmed disease-free, in order to multiple cropping.
