What is a Bordeaux mixture?

Bordeaux mixture, Bordo Mix in short, is a widely used fungicide made from the blend of slaked lime (Ca(OH)2) and copper(II) sulfate (CuSO4). Infestations of downy and powdery mildew as well as other fungi can be prevented in gardens, fruit farms and vineyards using this fungicide.

Preparation process of Bordo Mix:

Bordeaux mixture is a mixture of copper sulphate, hydrated lime (calcium hydroxide) and water in  various strengths. Traditionally, its composition can be described through the weight of copper sulphate, the weight of hydrated lime (calcium hydroxide) and the volume of water. The concentration of the Bordo Mix is determined by the percentage of the copper sulphate weight to the water weight. Thus, a 1% Bordeaux mixture has the formula 1 :1:100 (1 kg copper sulphate :1 kg hydrated lime :100 litres water). The copper content of a 1% Bordeaux mixture is between 0-25 % copper, as copper sulphate contains 25% copper metal. During the composition, lime quantity can be considerably reduced, as one kilogram of copper sulphate just requires 0.225 kilogram hydrated lime (calcium hydroxide) to deposit all the copper in the solid form. Presently, many good brands of hydrated lime is freely available, but the quality of it deteriorates on storage, therefore, it is recommended to do not exceed the a ratio of 2:1. (1:0.5:100 mixture) to be on safer side.

In the preparation process of  this mixture, a plastic or wooden container is used to dissolve copper sulphate in half the required amount of water. The hydrated lime is blended with the rest available water in another container. These two different solutions are then filtered using strainer and filled into any container or spray tank.
