春雷霉素

应用三环唑与春雷霉素的复配制剂灭稻瘟1号或采取三环唑与春雷霉素轮换施用均可有效地防治稻瘟病，防治效果达90%以上，同时减少化学农药施用量50%以上。

1 , a compound chemical of tricyclazole and kasugamycin . It is also effective by applying tricyclazole and kasugamycin alternatively . The prevention and control effect exceeded 90 % and the quantity of chemicals applied decreased more than 50 % .

春雷霉素的残留试验结果表现出随着施药剂量的增加而增大、施药次数的增加而增加的规律，而且春雷霉素主要残留在植烟土壤中，而在干烟叶中残留较小。

The results of residue of Kasugamycin followed the law that the residues increased with the increase of pesticide dose and the frequency of pesticide application , and the residue of kasugamycin was major in the soil planted tobacco , but less in the dry tobacco leaves .

这说明该方法可用于春雷霉素在烟田中的残留行为研究。

This shows that the method can be used to kasugamycin residues in the tobacco fields in behavior .

用建立的反相离子对高效液相色谱法和高效毛细管电泳法对春雷霉素发酵液、提炼液和原粉进行了含量测定，并对两种分析方法进行了比较。

The fermentation broth , extract liquor and the product of kasugamycin were determined by two established methods , i.e. ion pair reverse phase high performance liquid chromatography and high performance capillary electrophoresis .

春雷霉素和灭瘟素在叶瘟病发生初期及破肚期、齐穗期各喷施1次，对叶瘟防效为50.54%～72.67%，穗瘟为76.66%～87.42%，与化学杀菌剂三环唑相当。

Applied kasugamycin and blasticidin at the initial of rice leaf blast and the booting as well as heading stage , the efficacy was 50.54 % ~ 72.67 % for rice leaf blast and 76.66 % ~ 87.42 % for rice head blast , equal to tricyclazole .
