(US10212937) What is claimed is: 1. An aqueous solution comprising (a) monochloramine in an amount of 1 ppm to 100 ppm, and (b) at least one peracid in an amount of 1 ppm to 100 ppm, wherein the peracid is peracetic acid and wherein components (a) and (b) are present in a synergistically microbicidally effective combined amount to control the growth of at least one microorganism, wherein said synergistically microbicidally effective combined amount is demonstrated by a formula of QA/Qa+QB/Qb, wherein   Qa=Concentration of said monochloramine in parts per million, acting alone, which produced an end point to completely prevent growth of a bacteria,   Qb=Lowest concentration of said peracid in parts per million, acting alone, which produced an end point to completely prevent growth of said bacteria,   QA=Lowest concentration of said monochloramine in parts per million, in said aqueous solution, which produced an end point to completely prevent growth of said bacteria,   QB=Lowest concentration of said peracid in parts per million, in said aqueous solution, which produced an end point to completely prevent growth of said bacteria, and where the sum of QA/Qa and QB/Qb is less than one, and wherein said bacteria is Pseudomonas aeruginosa or Enterobacter aerogenes. 2. The aqueous solution of claim 1, wherein the pH of the aqueous solution is from about 5 to about 12. 3. The aqueous solution of claim 1, wherein the aqueous solution further comprises at least one base. 4. The aqueous solution of claim 1, wherein at least one pH control agent is present in a concentration so that the aqueous solution has a pH of from about 5 to about 12. 5. The aqueous solution of claim 2, wherein the pH is from 7 to 10. 6. The aqueous solution of claim 3, wherein the base comprises sodium hydroxide. 7. The aqueous solution of claim 3, wherein the base is present in a concentration so that the aqueous solution has a pH of from about 5 to about 12. 8. The aqueous solution of claim 3, wherein the base is present in a concentration so that the aqueous solution has a pH of from 7 to 10. 9. The aqueous solution of claim 4, wherein the pH control agent is at least one base or at least one acid. 10. The aqueous solution of claim 1, wherein the monochioramine is present in the aqueous solution at a concentration of 1 ppm to 75 ppm, and the at least one peracid is present in the aqueous solution at a concentration of from 1 ppm to 100 ppm. 11. A method of controlling the growth of at least one microorganism in or on a product, material, or medium susceptible to attack by a microorganism, the method comprising treating the product, material or medium with the aqueous solution of claim 1. 12. The method of claim 11, wherein the pH of the aqueous solution or the product, material or medium, or both, is from about 5 to about 12. 13. The method of claim 11, wherein the monochloramine is present in the aqueous solution at a concentration of from 1 ppm to 50 ppm, and the at least one peracid is present in the aqueous solution at a concentration of from 5 ppm to 100 ppm. 14. The method of claim 12, wherein the pH is from 7 to 10. 15. The method of claim 11, wherein the aqueous solution further comprises at least one base. 16. The method of claim 15, wherein the base comprises sodium hydroxide. 17. The method of claim 15, wherein the base is present in a concentration so that the aqueous solution has a pH of from about 5 to about 12. 18. The method of claim 15, wherein the base is present in a concentration so that the aqueous solution has a pH of from 7 to 10. 19. The method of claim 11, wherein at least one pH control agent is present in a concentration so that the aqueous solution has a pH of from about 5 to about 12. 20. The method of claim 15, wherein monochloramine and at least one base are combined in an aqueous fluid before adding the aqueous fluid to said product, material, or medium, and where at least one peracid is further added to the aqueous fluid before the adding or separately applied to the said product, material, or medium. 21. The method of claim 11, wherein said monochloramine is formed in-situ in said medium or in the presence of said product or material. 22. The method of claim 11, wherein the microorganism is a bacterium. 23. The method of claim 11, wherein the material or medium is wood pulp or paper, wood chips, lumber, paints, leathers, adhesives, coatings, animal hides, tanning liquor, paper mill liquor, fiberglass, dairy processing, poultry processing, meat packing facilities, meat processing, metalworking fluids, petrochemicals, pharmaceutical formulations, cooling water, recreational water, dyes, clays, mineral slurries, cationic surfactants, formulations with cationic surfactants, influent water, waste water, pasteurizers, retort cookers, cosmetic formulations, toiletry formulations, textiles, geological, drilling lubricants, or agrochemical compositions for crop or seed protection. 24. The method of claim 11, wherein the material or medium is in the form of a solid, a dispersion, an emulsion, or a solution. 25. A method for preventing or slowing down spoilage of a product, material, or medium caused by microorganism selected from bacteria, fungi, algae, or mixtures thereof, wherein the method comprises applying the aqueous solution of claim 1 to the product, material, or medium. 26. The method of claim 25, wherein the pH of the aqueous solution or the product, material, or medium, or both, is from about 5 to about 12. 27. The method of claim 25, wherein the material is seeds or crops. 28. The method of claim 25, wherein said product is a meat, vegetable, or fruit. 29. The method of claim 25, wherein said product is a food product. 30. The method of claim 25, wherein monochloramine and at least one peracid are applied separately to said product, material, or medium. 31. The method of claim 25, wherein the aqueous solution further comprises at least one base and wherein monochloramine and at least one base are combined in an aqueous fluid before adding the aqueous fluid to said product, material, or medium, and wherein at least one peracid is further added to the aqueous fluid before adding or separately applied to the said product, material, or medium. 32. The method of claim 25, wherein said material or medium is a surface, device, and/or machinery utilized in meat, vegetable, or fruit preparation or processing or packing.
