Comment

Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. The toxicity of copper sulfate depends on the copper content. Copper is an essential mineral. It can be found in the environment, foods, and water. Copper sulfate has been registered for use in pesticide products in the United States since 1956.

Uses of Copper Sulphate

Copper sulphate, blue stone, blue vitriol are all common names for pentahydrated cupric sulphate, CuSO₄5H₂O, which is the best known and the most widely used of the copper salts. Indeed it is often the starting raw material for the production of many of the other copper salts.

Today in the world there are more than 100 manufacturers and the world’s consumption is around 275,000 tonnes per annum. It is estimated that approximately three-quarters of this is used in agriculture, principally as a fungicide, but also for treating copper-deficient soils.

Uses

Copper sulphate is a very versatile chemical with as extensive a range of uses in industry as it has in agriculture. Its principal employment is in agriculture, and, up to a generation or so ago, about its only uses in industry were as a mordant for dyeing and for electroplating. Today it is being employed in many industrial processes:

The synthetic fibre industry has found an application for it in the production of their raw material
The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining, for copper coating steel wire prior to wire drawing and in various copper plating processes
The mining industry employs it as an activator in the concentration by froth flotation of lead, zinc, cobalt and gold ores
The printing trade takes it as an electrolyte in the production of electrotype and as an etching agent for process engraving
The paint industry uses it in anti-fouling paints and it plays a part in the colouring of glass.

Indeed, today there is hardly an industry which does not have some small use for copper sulphate. In the table below, some of the many uses of copper sulphate are listed.

Uses of Copper Sulphate

Classification	Application
Agriculture
Major uses	Preparation of Bordeaux and Burgundy mixtures for use as fungicides Manufacture of other copper fungicides such as copper-lime dust, tribasic copper sulphate, copper carbonae and cuprous oxide Manufacture of insecticides such as copper arsenite and Paris green Control of fungus diseases Correction of copper deficiency in soils Correction of copper deficiency in animals Growth stimulant for fattening pigs and broiler chickens Molluscicide for the destruction of slugs and snails, particularly the snail host of the liver fluke
Other uses	Seed dressing Soil steriliser, e.g Cheshunt compound (a mixture of copper sulphate and ammonium carbonate) to prevent ‘damping-off’ disease of tomato etc. Control and prevention of foot rot in sheep and cattle Bacteriastat for addition to sheep dips Disinfectant in prevention of the spread of swine erysepelas and white scours in calves Control of scum in farm ponds Plant nutrient in rice fields Preservative for wooden posts, wooden buildings, etc Ingredient of vermin repellents, e.g for application to bark of trees against rabbits Stimulant of latex yield on rubber plantations Protection against algal growths on flower pots
Public health and medicine
	Destruction of algal blooms in reservoirs and swimming pools Prevention of the spread of athletes foot in warm climates, by incorporation in the flooring mixture of swimming baths Control of bilharzia in tropical countries, as a molluscicide Prevention of malaria, in the preparation of Paris green for use against mosquito larvae Antiseptic and germicide against fungus infections Catalyst or raw material for the preparation of copper catalysts used in the manufacture of pharmaceutical products
