Copper sulfate pentahydrate is a fungicide. However, some fungi
were capable to adapt to elevated levels of copper ***** with lime
it is called Bordeaux mixture and used to control fungus on grapes,
melons, and other berries.Another application is Cheshunt compound,
a mixture of copper sulfate and ammonium carbonate used in
horticulture to prevent damping off in seedlings. Its use as a
herbicide is not agricultural, but instead for control of invasive
aquatic plants and the roots of plants near pipes containing water.
It is used in swimming pools as an algaecide. A dilute solution of
copper sulfate is used to treat aquarium fish for parasitic
infections, and is also used to remove snails from aquariums.
Copper ions are highly toxic to fish, so care must be taken with
the dosage. Most species of algae can be controlled with very low
concentrations of copper sulfate. Copper sulfate inhibits growth of
bacteria such as Escherichia coli.
