Action Principle of Potassium Dihydrogen Phosphite
Phosphite is a highly mobile molecule that can be easily absorbed by the leaves and roots of plants and moved throughout the plant. Therefore, phosphite can be used by foliar spraying and irrigation fertilization, and is quickly moved and absorbed through xylem and phloem.
Functional Characteristics of Potassium Dihydrogen Phosphite
1. It is a kind of water-soluble fertilizer with high phosphorus and high potassium. After application, crops can quickly supplement phosphorus, potassium and various trace elements, control and strengthen shoots, promote flower bud differentiation, expand fruit, mature early, increase yield and improve quality.
2. It can reduce the symptoms of element deficiency in crops, such as yellowing of leaves, deformity of leaves, leaflets, falling flowers, fruit cracking, and so on.
3. It is not easy to fix in the soil, it is easy to be absorbed, and the absorption and utilization rate is high.
4. It is not easy to antagonize with trace elements, and its pH value is neutral, so it can be mixed with most pesticides and fertilizers.
5. When the pathogen invaded, potassium dihydrogen phosphite could induce the seedling cells to produce lignin, increase the thickness and hardness of the cell wall, and prevent the pathogen from invading and expanding.
6. Trivalent phosphorus ion has a strong killing effect on fungi and bacteria, and can prevent and treat most diseases such as ulcers.
Applications of Potassium Dihydrogen Phosphite
- Agricultural Field: Potassium dihydrogen phosphite has important applications in the agricultural field. It is a highly effective phosphate fertilizer and antibiotic and is often used as a nutritional supplement for plants. Potassium dihydrogen phosphate can provide the phosphorus needed by plants and promote plant growth and development. At the same time, it also has antioxidant and antiviral effects, which can enhance the disease resistance of plants and improve yield and quality.
- Fungicides and Preservatives: Potassium dihydrogen phosphite can also be used as a fungicide and preservative. Because it has inhibitory effects on a variety of pathogenic bacteria and true shade, it is often added to pesticides to prevent and treat crop diseases. At the same time, potassium dihydrogen phosphate can also delay the decay process of fruits and vegetables, extend their shelf life, and reduce food loss.
- Industrial Production: In addition to its application in agriculture, potassium dihydrogen phosphite also plays an important role in industrial production. It can be used as an oxidizing agent, reducing agent and catalyst. In organic synthesis, potassium dihydrogen phosphite can participate in the oxidation reaction of alcohols and ethers to obtain the corresponding ketones and acids. At the same time, it can also reduce certain organic compounds to alcohols or ethers. In addition, potassium dihydrogen phosphite can also catalyze certain organic reactions and increase reaction rate and yield.
- Pharmaceutical Field: In the pharmaceutical field, potassium dihydrogen phosphite also has certain applications. Due to its antioxidant and antiviral properties, it can be used to prepare antioxidant and antiviral drugs. In addition, potassium dihydrogen phosphate can also be used as an antibacterial agent to treat some bacterial infections.
It should be noted that although potassium dihydrogen phosphite has a variety of applications, it still needs to pay attention to safety in the process of use. It has a certain irritation and corrosiveness, after contact with the skin and eyes should be cleaned in time to avoid long-term contact. At the same time, in the process of storage and transportation, it is also necessary to avoid reacting with other substances, fire sources, and high temperatures.
As an important compound, potassium dihydrogen phosphite is widely used in agriculture, industry, medicine, and other fields. It can not only be used as a plant nutritional supplement to promote plant growth and development, but also can be used as a fungicide and preservative to prolong the shelf life of food. In addition, potassium dihydrogen phosphite also plays an important role in industrial production and medicine. However, in the process of use, we need to pay attention to safety and avoid adverse reactions with other substances. Through reasonable application, potassium dihydrogen phosphite can make a positive contribution to human agricultural production and industrial development.
