EC No.: 604-162-9
Molecular Weight: 120.0776
Molecular Formula: KH2PO3
Structure: 
MPP (KH2PO3) has obvious bactericidal effect, especially killing Botrytis cinerea, Fusarium oxysporum cucumber-specific type, Fusarium oxysporum watermelon-specific type, Gibberella zeae, Pythium graminosa, and Rhizoctonia glutinosa, Sclerotinia sclerotiorum and Verticillium dahliae and have significant effects.
It is currently the first choice for non-agrochemical control and environmentally friendly raw material.
2. In the field of fertilizer application, mono potassium phosphite (MPP) is an important source of high-purity potassium fertilizer.
Phosphorous acid can be metabolized into phosphoric acid by soil microorganisms in the roots and becomes one of the main fertilizers for plants. It has the dual functions of potassium fertilizer and phosphate fertilizer.
No pollution, no toxicity & no residue.
3. In industrial circulating water, Mono potassium phosphite (MPP) can be used as bactericide and a complexing agent for calcium and magnesium ions, which can reduce environmental pollution.
