Description
技术领域
本发明涉及化合物制备技术领域,尤其涉及一种霜脲氰铜及其制备方法、应用。
背景技术
霜脲氰是一种高效、低毒杀菌剂,其作用机理是通过抑制病原菌的细胞线粒体中的电子转移、使其氧化和磷酸化的作用停止,从而使病原菌细胞丧失能量来源而死亡。主要对真菌的类脂化合物的生物合成和细胞膜机能起作用,抑制孢子萌发、牙管伸长、附着胞和菌丝的形成。是触杀和预防性杀菌剂,对卵菌纲的霜霉、疫霉和单轴霉有效。
但是霜脲氰存在杀菌谱较窄的缺点,除卵菌外对其它真菌和细菌无效。此外,霜脲氰持效期短,且易诱使病菌产生耐药性。
因此,现有技术还有待于改进和发展。
发明内容
鉴于上述现有技术的不足,本发明的目的在于提供一种霜脲氰铜及其制备方法、应用,旨在解决现有霜脲氰作为杀菌剂杀菌谱窄的问题。
