| [Uses]
Monopotassium phosphite can be used as a fungicide and as a chelating agent for calcium and magnesium ions. It can also serve as a substitute for organophosphorus-based water-treatment agents, thereby reducing environmental pollution. | [Preparation]
Potassium dihydrogen phosphite is synthesised by the reaction of phosphorous acid with potassium hydroxide. | [Mechanism of action]
Mixed mode of application including direct toxicity to plant pathogens reducing populations and promotion of plants natural defences | [Pesticide Type]
