人类使用铜制剂已有200多年历史了,铜制剂堪称杀菌剂中的“老字号”。1761年,人们用硫酸铜处理小麦种子防治腥黑穗病;1800年,法国发现波尔多液的化学性质;1882年,法国波尔多大学教授米拉德(P.M.A.Millardet)发现波尔多液防治葡萄霜霉病的作用;1922年,哈利尔(M.Khalil)报道硫酸铜处理水坑防治钉螺有效。铜制剂之所以一直沿用至今,青春永驻,历久不衰,是因为它具有卓越的综合性能:①生产原料易得,工艺相对简单;②抗药性发展缓慢,药效稳定;③低毒低残,安全无公害。全国农技中心
Human use of copper preparations for more than 200 years of history, copper agents called fungicides in the “old name.” In 1761, people treated the seeds of wheat with copper sulfate for the control of the fish head smut. In 1800, France discovered the chemical properties of the Bordeaux mixture. In 1882, PM Salillarde, a professor at the University of Bordeaux, France, discovered that Bordeaux mixture against grape downy mildew In 1922, M. Khalil reported that copper sulfate treatment of potholes was effective in controlling snails. The reason why copper has been used up to now, youth forever, everlasting, because it has excellent overall performance: ① production of raw materials is easy, the process is relatively simple; ② drug resistance slow development, efficacy and stability; ③ low toxicity and low residue , Safe and pollution-free.
