1. What is potassium dihydrogen phosphite, an organosilicon elastomer?
Potassium dihydrogen phosphite, a chemical with the molecular formula KH2PO3, can be used as a direct sterilizer in industrial circulating antioxidant water. agent and complexing agent for calcium and magnesium ions. : Water treatment agent that can replace organophosphines to reduce environmental pollution.
2. The current market status of potassium dihydrogen phosphite
In China, potassium dihydrogen phosphite is often added as a chemical intermediate by a few fertilizer companies. Overseas, potassium dihydrogen phosphite is used as a A pesticide ingredient is officially registered for use as a fungicide. It is mainly used as an auxiliary in fungicides to enhance efficiency. At present, potassium phosphite has not yet obtained a registration certificate in China. Many companies are operating in the form of a large number of element certificates or high-content phosphorus and potassium exemption from registration. .
3. How potassium dihydrogen phosphite works
Phosphite is a highly mobile molecule that can be easily absorbed by the leaves and roots of plants and circulates throughout the plant. move. Therefore, phosphorous acid can be applied through foliar sprays and fertigation, and is quickly moved and absorbed through the xylem and phloem.
IV. Functional characteristics of potassium dihydrogen phosphite:
1. It is a high-phosphorus and high-potassium fully water-soluble fertilizer. After application, crops can quickly replenish phosphorus, potassium and other nutrients. Plant trace elements to control and strengthen crop shoots, promote flower bud differentiation, fruit expansion, early maturity, increase yield, and improve quality.
2. Reduce nutrient deficiency symptoms in crops, such as leaf yellowing, deformity, small leaves, flower drop, fruit cracking, etc.
3. It is not easily fixed in the soil, easy to be absorbed, and has high absorption and utilization rate.
4. It is not easy to antagonize trace elements, has a neutral pH value, and can be mixed with most pesticides and fertilizers.
5. When pathogenic bacteria invade, potassium dihydrogen phosphite can induce seedling cells to produce lignin, increase the thickness and hardness of cell walls, and prevent the invasion and expansion of pathogenic bacteria.
6. Trivalent phosphorus ions have a strong killing effect on fungi and bacteria, and have preventive and therapeutic effects on most diseases such as ulcers.
7. Potassium dihydrogen phosphite is a registered fungicide abroad, resistant to diseases such as downy mildew, powdery mildew, scab, Phytophthora, root rot, etc.
