Copper sulfate pentahydrate CAS NO.7758-99-8

1. After copper sulfate is applied to the affected crop plants, the liquid will be attached to the surface of the bacterial body, and copper ions can enter the bacterial body and act on the cell protein, so that the bacterial body can not carry out metabolic activities and die.

2, at the same time, copper ion is the main component of a variety of biological enzymes, after being absorbed by crops, can enhance the ability of vegetable plants to resist the invasion of pathogens. 3. According to the determination, applying copper sulfate once can meet the absorption and utilization of copper in crops for 2-3 years, the pH value in the soil can be below 7, and the content of organic matter is relatively high, especially the application of copper sulfate in old vegetable fields has a better effect of disease prevention and growth promotion.

4, Copper sulfate, copper hydroxide, quinoline copper and other copper preparations are commonly used in the prevention and control of vegetable diseases, with a wide bactericidal spectrum, long duration characteristics, especially copper sulfate as a plant protective inorganic agent, applied before the onset of vegetable crops, has a defensive role, in the early onset of the application has a rapid killing of bacteria, but also stimulate wound healing.
