Cuprous oxide is a monovalent copper oxide, and cuprous oxide produced by Taihe Metal is mainly used for antifouling paints and insecticides in ships.
An important product of cuprous oxide for insecticides is the master of copper. The master of copper is a protective and therapeutic broad-spectrum inorganic copper fungicide produced by Norwegian laboratories (the world famous mineral source fungicide manufacturer). It is used to control fungal and bacterial diseases of crops such as fruit trees, vegetables, flowers and food. The general name is cuprous oxide, the dosage form is 86.2% cuprous oxide wettable powder high-electric type, 86.2% cuprous oxide water-dispersible granules, and the mastery of copper masters in the global manufacturing technology is the leading competitive scale. The world’s top copper preparations have become the first choice for government procurement, organic agriculture and farmers’ disease prevention.
Mechanism of action: mainly by releasing copper ions, and acting on groups such as -SH, -N2H, -COOH, -OH in proteins in fungi or bacteria, leading to the death of pathogens. The content and release capacity of copper ions are the main factors determining the bactericidal and disease-preventing effect of copper preparations.
Pharmacy characteristics
1) High content and high activity copper-containing fungicides rely on copper ions. 86.2% cuprous oxide contains 1-4 times more copper than other copper preparations, and has stronger bactericidal power.
2) Safety High-tech upgraded copper masters have better mix and safety. Copper masters are monovalent copper. When sterilizing, monovalent copper is converted into divalent copper, and copper ions are slowly released. Most of the inorganic copper is divalent copper, which releases copper ions directly, aggregates, and rapidly erupts. So the copper master is safer.
3) Non-polluting low residue Low toxicity is certified by organic products in the United States, Japan and the European Union, and can be used in organic agricultural production, which is conducive to the export of agricultural products.
Control object and method of use
86 countries around the world are widely used in fruit trees, vegetables, flowers, lawns, oilseeds and food crops;
