波尔多液（法语：bouillie bordelaise）是硫酸铜（CuSO4）和熟石灰（Ca(OH)2）按不同比例配制成的蓝色胶状悬浊液，用作杀真菌剂。波尔多液自19世纪末期于法国波尔多地区的葡萄酒庄首先使用，故此得名，后来广泛用于苹果、梨、柑橘和香蕉的防护。波尔多液开创了将无机化学品用于防止植物病害的先河，之后价廉易得的各种无机杀菌剂不断出现。

Bordeaux mixture 波尔多液
Bordeaux mixture (also called Bordo Mix) is a mixture of copper(II) sulfate (CuSO4) and slaked lime (Ca(OH)2) used as a fungicide. It is used in vineyards, fruit-farms and gardens to prevent infestations of downy mildew, powdery mildew and other fungi. It is sprayed on plants as a preventative; its mode of action is ineffective after a fungus has become established. It was invented in the Bordeaux region of France in the late 19th century. If it is applied in large quantities annually for many years, the copper in the mixture eventually becomes a pollutant.
