Copper Sulfate

Applications


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. The idea is that you cut down a tree, drill a hole in the trunk, and pour copper sulfate down the hole and it will kill the tree.     

​(Other Uses)  Seed Dressing    Soil sterilizer, e.g. Cheshunt compound (a mixture of copper sulfate 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 erysipelas and white scours in calves    Control of scum in farm ponds    Plant nutrient in rice fields    Preservative for wooden posts, wooden buildings, etc.    Preservative for wooden fruit boxes, planting baskets and other containers    Ingredient for vermin repellents, e.g. for application to bark of trees against rabbits    Stimulant of latex yield on rubber plantations    Protection against algal growth on flower pots
