有效霉素及井岗霉素是近年来国内外研制成功的新农用抗菌素。有效霉素(Validamycin)是一种从吸水放线菌中提取出来的抗菌素,其产生菌为吸水放线菌柠檬变种(Streptomyces hygrosropicus Var.Limoneus)。日本在1966年开始研制,1972年正式投产,目前年产2000多吨,被定为防治稻纹枯病的特效新药剂。有效霉素对稻纹枯病及其他作物菌核类病害(包括水稻小球菌核病)有很好的防效,与田安相比,防效稳定在80～90％。对人畜安全,
Validamycin and Jinggangmycin is a new agricultural antibiotic successfully developed at home and abroad in recent years. Validamycin is an antibiotic extracted from actinomycetes that is an actinomycete that produces Streptomyces hygrosropicus var. Limoneus. Japan started its research in 1966 and formally put it into operation in 1972. At present, it has an annual output of over 2,000 tons and is designated as a new pharmaceutical agent for the control of rice sheath blight. Validamycins against rice sheath blight and other crops sclerotiorum disease (including rice sclerotinia) has a good control effect, and Tian security, the control effect is stable at 80 ~ 90%.
