Copper Sulfate, CAS No. : 144-55-8

Copper sulphate can be used to kill fungi. It is mixed with lime water to form Bordeaux mixture.
It is used as a fungicide to control fungi on crops such as lemon and grape, and to prevent fruit from decaying. Dilute solutions are used for sterilization in aquariums and for removing snails. Since copper ions are toxic to fish, the amount must be strictly controlled. Most fungi can be killed with very low concentrations of copper sulfate, and E. coli can also be controlled. In addition, the aquaculture industry is also used as the main raw material for trace element copper in feed additives.
