NOVELTY - Manufacturing an aqueous fungicide, bactericide and fertilizer solution, comprises: dissolving phosphorous acid in phosphoric acid to form a solution of an acid mixture; reacting the acid mixture with aqueous potassium hydroxide solution at 65-260 degrees C in continuous reactor while maintaining the ratio of potassium to phosphorus at 1:1-2:1 to form a reaction mixture comprising potassium phosphates, potassium polyphosphates, potassium phosphites, and potassium polyphosphites and potassium phosphate phosphite copolymers; and cooling the reaction mixture rapidly at least 1-60 degrees C, to below 35-65 degrees C.    USE - The processes are useful for manufacturing aqueous fungicide, bactericide and fertilizer solution, which is useful for fertilizing and treating a plant for a microbial infection, fungal infection and/or bacterial infection (all claimed). Test details are described but no results given.    ADVANTAGE - The process: is a single step process and does not produce any toxic byproducts, hence economical and safe; and utilizes the polymeric components that have a higher analysis with long term storage stability, thus providing the fungicidal and fertilizer composition, which can remain, as a clear solution, when stored for extended periods of time without salting out, than the conventionally produced orthophosphorus products, and causes less foliage burn when applied directly to the plants.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) manufacturing (II) an aqueous fungicidal and bactericidal solution having fertilizer properties, comprising: dissolving phosphorous acid in water to form an aqueous phosphorous acid solution having a concentration of 50-80 wt.% phosphorous acid; reacting the aqueous acid solution with an aqueous potassium hydroxide solution at 50-200 degrees C in a continuous reactor while maintaining the ratio of potassium to phosphorus in a molar ratio of 2:1-3:1, thus forming an aqueous potassium polyphosphite solution comprising potassium phosphites, dipotassium phosphite, and potassium polyphosphites; and cooling the reaction mixture rapidly at least 25 degrees C to below 25-75 degrees C;    (2) the aqueous solutions made by the above processes having a pH of 6-8.5;    (3) a dual phosphorous acid combination solution formed by dissolving phosphorous acid and phosphoric acid in a ratio of 1:99-99:1 parts; and    (4) a batch process for manufacturing of an aqueous fungicide, bactericide and fertilizer solution, comprising: dissolving phosphorous acid in phosphoric acid to form a solution of an acid mixture; reacting the acid mixture with aqueous potassium hydroxide solution while controlling the temperature at 50-200 degrees C in a temperature controlled reactor, and controlling the ratio of potassium to phosphorus in a molar ratio of 1:1-2:1, thus forming a reaction mixture comprising potassium phosphates, potassium polyphosphates, potassium phosphites, and potassium polyphosphites and potassium phosphate phosphite copolymers; and cooling the reaction mixture rapidly at least 25 degrees C to below 25-75 degrees C.
