春雷霉素
Kasugamycin
化合物简介
Kasugamycin (Ksg) is an aminoglycoside antibiotic that was originally isolated in 1965, from Streptomyces kasugaensis, a Streptomyces strain found near the Kasuga shrine in Nara, Japan. Kasugamycin was discovered by Hamao Umezawa, who also discovered kanamycin and bleomycin, as a drug which could prevent growth of a fungus causing rice blast disease. It was later found to inhibit bacterial growth also. It exists as a white, crystalline substance with the chemical formula C14H28ClN3O10 (kasugamycin hydrochloride). It is also known as kasumin.

生产方法及用途
生产方法
我国春雷霉素是一种小金色放线菌(Actinomycetes microaurous)所产生的代谢物。日本春日霉素是放线菌(Streptomyces kasugaensis)产生的代谢物。 1.该品是农医两用抗菌素。春雷霉素对稻瘟病菌有强烈的抑制作用,用春雷霉素40μg/ml(每亩用量4g)喷雾,对苗瘟、叶瘟、穗颈瘟具有显著的治疗和保护用作,防治效果达70-85%,略优于或相当于600倍稻瘟净。与稻瘟净混用,可将防治效果提高到97%,还可延缓抗菌株的产生。低毒、内吸性杀菌剂。主要用于防治稻瘟病,在水稻抽穗期和灌浆期施药,通过内吸治疗作用发挥药效。防治稻瘟病用2%可湿性粉剂500~700倍液在发病初期施药,7~10d喷一次,叶瘟、穗颈瘟各2次。
