The most important use of phophrous acid is the production of phosphites which are used in water treatment. Phosphorous acid is also used for prepareing phosphite salts, such as potassium phosphite. These salts, as well as aqueous solutions of pure phosphorous acid, are fungicides. Phosphites have shown effectiveness in controlling a variety of plant diseases, in particular, treatment using eigher trunk injection or foliar containing phosphorous acid salts is indicated in response to infections by phytophthora and pythium-type plant pathogens (both within class oomycetes, known as water molds), such as dieback/root rot and downymildew.
Raw material of the manufacture for phosphite and plastic stabilizers. Reducing agent in chemical reaction, And used synthetic fibre and agro-chemicals industry.
