柑桔溃疡病防治药剂的筛选研究

 对24种药剂进行柑桔溃疡病菌的室内毒力筛选。结果表明，噻霉酮、溴菌腈和农用链霉素的抑菌效果较好。选择噻霉酮、溴菌腈、农用链霉素、菌立清、松脂酸铜、甲基硫菌灵·异菌脲等10种药剂进行田间药效试验，春雷霉素400倍液（防效7863%）、噻霉酮900倍液（防效7701%）、琥胶肥酸铜600倍液（防效7346%）、农用链霉素1000倍液（防效7277%）对柑桔溃疡病防治效果较好，推荐生产上使用生物制剂春雷霉素及农用链霉素。

Screening of Control Bactericides of Xanthomonas axonopodis pv. citri

In order to screen high effective medicaments, 24 fungicides which had strong antimicrobial effect on the strain Xanthomonas axonopodispv.citriwere chosen. The results showed that the effect of benziothiazolinone, JP2]streptomycin and bromothalonil were stronger. Field experiments of 10 tested fungicides indicated that the control effects of kasugamycin 400×（the efficacy values of 78.63%）, benziothiazolinone 900×（the efficacy values of 77.01%）and copper（succinate+glutarate+adipate）600×（the efficacy values of 73.46%）were significant. Kasugamycin and streptomycin, derived from biological agents, were recommended as the routine bactericides for the control of citrus canker.
