铜制剂靠释放出铜离子与真菌体内蛋白质中的-SH、-NH2、-COOH、-OH等基团起作用,导致病菌死亡。铜制剂分为无机铜、有机铜两大类,目前仍以无机铜为主。市场上流行的无机铜制剂有:硫酸铜、碱式硫酸铜、氧化亚铜(铜大师)、氧氯化铜(王铜)、氢氧化铜等。但是,无机铜制剂有几点不足: Copper preparations by the release of copper ions and fungi in vivo proteins - SH, -NH2, -COOH, -OH and other groups play a role, leading to death of bacteria. Copper preparations into inorganic copper, organic copper two categories, is still mainly inorganic copper. The market of inorganic copper preparations are: copper sulfate, basic copper sulfate, cuprous oxide (Master Copper), copper oxychloride (copper), such as copper hydroxide. However, inorganic copper preparations have several shortcomings:
