Introduction: Potassium dihydrogen phosphite, a chemical with the molecular formula KH2PO3, can be used as a direct fungicide and a complexing agent for calcium and magnesium ions in industrial circulating water A water treatment agent that can replace organic phosphines and reduce environmental pollution. The principle of action is that phosphite chemicalbook salts are highly mobile molecules that can be easily absorbed by the leaves and roots of plants and move throughout the entire plant body. So, phosphite can be used through foliar spraying and irrigation fertilization, and is quickly moved and absorbed through the xylem and phloem.
Uses of potassium dihydrogen phosphite
- In terms of pesticides, it is mainly used as intermediates of pesticides and fungicides. Potassium dihydrogen phosphite (KH2PO3) has obvious bactericidal effects, especially killing Botrytis cinerea, Fusarium oxysporum Cucumber Specialized Type, Fusarium oxysporum Watermelon Specialized Type, Gibberella Zea, Pythium Fruit, Pythium Rhizoctonia cerealis, Sclerotinia sclerotiorum and Verticillium dahliae have significant effects. It is currently the first choice for non-pesticide control and environmentally friendly raw materials.
- 2 In the field of fertilizer application, potassium dihydrogen phosphite (KH2PO3) is an important source of high-purity potassium fertilizer. In the later stage, phosphorous acid can be metabolized by soil microorganisms into phosphoric acid in the roots, and it becomes one of the main fertilizers for plants. It has the dual functions of potash fertilizer and phosphate fertilizer. After use, it has the advantages of non-polluting, non-toxic, and no residue.
- Potassium dihydrogen phosphite (KH2PO3) can be used as a direct bactericide and complexing agent of calcium and magnesium ions in industrial circulating water, which can replace organic phosphine water treatment agent and reduce environmental pollution.
