宁南霉素是一种胞嘧啶核苷肽型新抗生素,是一种广谱性生物农药,对烟草花叶病毒病,小麦白粉病、蔬菜白粉病、水稻白叶枯病等有显著的防治增产效果。以毒性试验证明,该抗生素属低毒、低残留、无“三致”和蓄积作用。成品在常温下存放两年。仍保留90%的生物活性,表明该抗生素稳定,符合市场农药要求。经四川、云南、山东三省六点四年共33832亩的大田试验证明宁南霉素对烟草花叶病毒病、小麦白粉病、蔬菜白粉病、水稻白叶枯病相对防治效果一般为70-95%,最高达100%,增产效果一般为25%-37%。达到或优于现有化学农药粉锈宁、硫磺胶悬剂、植物灵、83增抗剂和菌毒清。用药成本除略高于植物灵外,均低于其他化学农药亩用
Ningnanmycin is a new cytosine peptide-type antibiotic and is a broad-spectrum biological pesticide. It has significant prevention and treatment of tobacco mosaic virus disease, wheat powdery mildew, vegetable powdery mildew, rice bacterial leaf blight and so on. Increase production effect. The toxicity test showed that the antibiotic was low-toxicity, low-residue, non-reactive, and accumulative. The finished product is stored at room temperature for two years. 90% of the biological activity is still retained, indicating that the antibiotic is stable and meets the market pesticide requirements. A total of 33,832 acres of field trials in Sichuan, Yunnan, and Shandong provinces demonstrated that the relative control effect of ningnanmycin on tobacco mosaic virus disease, wheat powdery mildew, vegetable powdery mildew, and rice bacterial blight was generally 70-95. %, up to 100%, and the effect of increasing production is generally 25% -37%. Reached or better than existing chemical pesticide triadimefon, sulfur rubber suspension, plant spirit, 83 activator and mycotoxin. The cost of medication is slightly higher than that of plant spirits and lower than that of other chemical pesticides.
