摘　　要：本文研究了桑疫病菌的侵染循环,并进行了药效测定及田间防治试验。结果表明,桑疫病菌随病残体在灭菌土内,自然土表,自然土内10cm 深处以及桑树上均可存活到翌年5月份。病菌在灭菌土内和自然土表可存活到翌年6月份。说明在我省桑疫病菌可在病残体上越冬。室内药效测定表明,利克菌、70%百菌清、卡郡霉素和硫酸链霉素对桑疫病菌具有较好的抑制作用,其次为DTMZ 和多氧霉素,田间防治试验指出DT 防治效果最好,其次为DTMZ,其防治效果分别为85.5%和45%。Studies on infection cycle and control of mulberry bacterial blight and the inhibition of pesticides or antibiotics against the pathogen of the disease (Pseudomonas syringae p.v.mori (Boyer & Lambert 1893) Young,Dye & Wilkie 1978) revealed that pathogen in dis-eased tissues of mulberry could survive till May next year in sterilized soil,on the surfaceand 10cm deep under the surface of field soil as well as on the mulberry trees.Thepathogen even survived till June next year in sterilized soil and on the surface of field soil.Itwas suggested that P.syringae p.v.mori could over-winter in diseased tissues in Shandongprovince.On Petri dishes,Likejun,75% chlorothalonil,kanamycin and streptomycinsulfate gave excellent inhibition against the pathogen.Next came DTMZ and ployoxin.Inthe fields DT gave the best control effects and next came DTMZ.Their control effects were85.5% and 45%,respectively.
