What disease is treated by basic copper sulfate?

Basic copper sulfate is a commonly used fungicide, which is suitable to be used before and at the initial stage of the disease, so what disease does basic copper sulfate treat?

The basic shape of basic copper sulfate

Basic copper sulfate is a green monoclinic crystal with little solubility in water and can dissolve in dilute acid and ammonia.

The crude drug is a light blue viscous flow suspension with a suspension rate of more than 90%, pH 6: 8, qualified cold and hot storage stability, stable storage for 3 years at room temperature, fine particle size, and can be mixed with water in any proportion to form a relatively stable suspension.

Basic copper sulfate does not contain any harmful impurities, is not easy to produce drug damage, is resistant to Rain Water erosion, does not leave any residue on the plant surface, has no drug resistance, and can be mixed with general pesticides, such as 1605, omethoate, monocrotophos, malathion, phoxim and pyrethroids pesticides.

Second, what disease does basic copper sulfate treat?

Basic copper sulfate is a broad-spectrum protective fungicide, which can treat most of the fungal damage and bacterial diseases of plants. Basic copper sulfate is generally used before or at the initial stage of the disease, and should not be mixed with stone-sulfur mixture and pesticides decomposed by copper.

The mechanism of action is as follows: when the agent is sprayed on the plant surface, because the plant secretes acidic liquid in the process of metabolism and the acidic substance secreted by bacteria invading plant cells, the basic copper sulfate is transformed into soluble matter, and a small amount of soluble Cu2+,Cu2+ is produced to coagulate the cell protein.

At the same time, Cu2+ can also destroy some enzymes in the cells, thus hindering the normal metabolism. Cu2+ can also be poisoned by exchange and adsorption with cations (H +, Cd2+, K +, NH4+) on the plasma membrane.
