Copper(II) sulfate CAS# 7758-98-7

Copper(II) sulfate can be used to kill fungi. It is mixed with lime water to produce a Bordeaux solution, which is used to control fungi on crops such as lemons and grapes. 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 require only very low concentrations of Copper(II) sulfate to be killed. In addition, Copper(II) sulfate can also be used to control E. coli. The aqueous solution of ketone sulfate has a strong fungicidal effect and is mainly used in agriculture to control many diseases of fruit trees, malt, potatoes, and rice with good effect, but it has a poor effect on rust and powdery mildew. At the same time, the plant produces drug damage, while only on the copper ion drug tolerance of crops or dormant fruit trees used. It is a preventive fungicide and needs to be used before the onset of disease. It can also be used to remove algae from rice fields and ponds. It is also a trace element fertilizer, which can improve the stability of chlorophyll, prevent chlorophyll from being destroyed prematurely, promote crop absorption, crop loss of green when copper is deficient, and fruit trees when copper is deficient, the fruit is small, the flesh becomes hard, and in serious cases, the fruit trees die. crops sensitive to copper are cereal crops such as wheat, barley, oats, etc. It is mainly used for seed treatment and extra-root fertilization.
