Copper Sulfate


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 sulfate, copper carbonate 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   Tree stump removal.
