What diseases can basic copper sulfate prevent and control?

Basic copper sulfate is a commonly used fungicide, suitable for use before the onset of disease and in the early stages of infection, so what diseases does basic copper sulfate treat?

1. Basic physical form of basic copper sulfate

Basic copper sulfate is a green monoclinic crystal, with very low solubility in water, and is soluble in dilute acids and ammonia water.

The technical material is a light blue viscous flowing suspension, with a suspension rate greater than 90%, pH 6 to 8, qualified cold and heat storage stability, stable for 3 years under normal temperature storage conditions, 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 prone to causing phytotoxicity, resists rain erosion, leaves no residue on plant surfaces, has no resistance, and can be mixed with general pesticides, such as 1605, omethoate, monocrotophos, malathion, phoxim and pyrethroid pesticides, etc.

2. What diseases does basic copper sulfate treat?

Basic copper sulfate is a broad-spectrum protective fungicide that can treat most fungal damage and bacterial diseases of plants. Basic copper sulfate is generally used before the onset of disease or in the early stages of infection, and should not be mixed with lime sulfur mixture or pesticides that decompose upon contact with copper.

The mechanism of action is: after the agent is sprayed on the plant surface, because the plant secretes acidic liquid during metabolism, as well as the acidic substances secreted when pathogens invade plant cells, basic copper sulfate is converted into soluble substances, producing a small amount of soluble Cu2+, and after Cu2+ enters the pathogen cells, it coagulates the cell proteins.

At the same time, Cu2+ can also damage a certain enzyme in the cells, thereby hindering the normal progress of metabolism. Cu2+ can also undergo exchange adsorption with cations on the cytoplasmic membrane (H+, Cd2+, K+, NH4+) and thereby cause poisoning.
