抗生素在临床治疗方面起了相当大的作用。在农业上,作为杀菌剂的开发方面,也取得了卓越的成效。但在害虫防治上,虽有金链菌素(Aureothin)、抗霉素A(AntimycinA)、杀粉蝶素(Piericidin)、环已酰亚胺(Cycloheximide)等杀虫抗生素的报道,因毒性大、对植物有药害、不稳定等各种缺点而不能商品化。迄今只有四抗菌素(Tetranactin)由于其药效好、对螨类不易产生抗性、对温血动物几乎无毒、不留残毒、不污染环境等优点,在1973年被批准商品化,成 Antibiotics play a considerable role in clinical treatment. In agriculture, the development of fungicides has also achieved remarkable results. However, although there are reports of insecticide antibiotics such as Aureothin, Antimycin A, Piericidin and Cycloheximide in pest control, Plants have phytotoxicity, instability and other shortcomings can not be commercialized. To date, only Tetranactin has been approved for commercialization due to its good efficacy, resistance to mites, little to no toxicity to warm-blooded animals, no residual toxicity, no environmental pollution, etc.
