三唑类杀菌剂是重要的农用杀菌剂,具有高效、广谱的杀菌作用,具有内吸性,有保护、治疗和铲除作用,其作用机制是抑制菌体内的麦角甾醇的生物合成,这类杀菌剂从70年代开始发展以来,迄今已30余年,还经久不衰,至今还有较多的新品种上市,有较多的科学家继续在保留三唑环的结构下修饰结构,以期获得新的杀菌剂。我国从70年代后期首先由南开大学有机元素研究所、上海市农药研究所和江苏省建湖农药厂等 Triazole bactericide is an important agricultural bactericide, has high efficiency, broad-spectrum bactericidal effect, has systemic absorption, protection, treatment and eradication. Its mechanism is to inhibit the biosynthesis of ergosterol in bacteria. Since the development of fungicides in the 1970s, they have been used for more than 30 years and are still enduring. There are still many new varieties on the market. More scientists continue to modify the structure under the structure of the triazole ring in order to obtain new ones. Fungicides. In the late 70’s in China, the Institute of Organic Elements of Nankai University, Shanghai Institute of Pesticides, and Jianhu Pesticide Factory of Jiangsu Province were the first
