| introduction | potassium dihydrogen phosphite, a chemical with molecular formula KH2PO3, can be used as a direct fungicide and complexing agent for calcium and magnesium ions in industrial circulating water.: Water treatment agent that can replace organic phosphine and reduce environmental pollution. |
| Principle of Action | Phosphite is a highly mobile molecule that can be easily absorbed by the leaves and roots of plants and move throughout the plant. Therefore, phosphorous acid can be used by foliar spraying and irrigation fertilization, and is quickly moved and absorbed through xylem and phloem. |
| effect | 1. it is a water-soluble fertilizer with high phosphorus and potassium. after application, crops quickly supplement phosphorus, potassium and various trace elements to control and strengthen crops, promote flower bud differentiation, expand fruits, mature early, increase yield and improve quality. 2, reduce crop deficiency symptoms, such as leaf yellowing, deformity, leaflet, flower, fruit cracking and other phenomena. 3. It is not easy to fix in the soil, easy to be absorbed, and the absorption utilization rate is high. 4. It is not easy to antagonize with trace elements, the PH value is neutral, and it 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 wall, 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 in foreign countries, resistant to diseases, frost mold, powdery mildew, black star disease, Phytophthora, root rot, etc. |
| use | can be used as a direct fungicide and complexing agent for calcium and magnesium ions in industrial circulating water, which can replace organic phosphorus water treatment agent and reduce environmental pollution |
