copper sulfate pentahydrate Copper Sulphate Pentahydrate CuSO4.5H2O blue powder
Copper(II) sulfate pentahydrate is a fungicide. However, some fungi are able to adapt to increased levels of copper ions. Mixed with lime it is usually called Bordeaux mixture and is used to control fungus on grapevines, melons and other berries.
Its use as a herbicide is not agricultural, but to control attacks on aquatic plants and plant roots with pipes containing water. It is also used in swimming pools as an algaecide. An aqueous solution of copper sulfate is used to treat aquarium fish for parasitic infections, and is also used to remove snails from the aquarium.
Copper(II) sulfate pentahydrate is dissolved in water along with additives before the wood is placed in the tube. When the tube is pressurized, the chemicals are absorbed by the wood, giving the wood fungicide, insecticide, and ultraviolet light reflecting properties that help preserve it.
