柑桔溃疡病高效防除技术研究及应用

Study and Application on Effective Technique for Eradicating Citrus Canker

通过7年的研究、试验与示范,从33种对比处理中,筛选总结出一套快速防除柑桔溃疡病的新方法和操作程序。1986年以来,先后在贵州省9个县、市的38个点对74564株病树及676732株病苗进行一次性处理,均获成功。首批被治愈的大树和苗木,历时7年未再发病;用敏感的酶联免疫(ELISA)吸附技术对病原进行定性动态监测,未查到溃疡病菌。

A set of rapid'new eradicating technique of citrus canker without cutting out infected trees or destroying infected seedlings has been confirmed through 33 comparison tests after 7 years, study. Based on these proce-dures 74564 infected trees and 676732 infected seedlings were successfully cured by only once treatment in 38 area of 9 counties (city) of Guizhou Province since 1986. The symptom of citrus canker of the trees cured hasn't been found for 7 years and the bacteria have not been detected by using sensitive enzyme-linked im-munosorbent assay (ELISA).
