Abstract: An environmentally friendly process for treating crops, especially sweet potatoes, to prevent or at least inhibit deterioration of the edible plant matter, involves contacting the plant matter with an aqueous composition including phosphonic acid, also known as phosphorous acid, together with at least one of citric acid, phosphoric acid and sulfuric acid, preferably at least phosphoric acid, sufficient to lower the treating water to a pH of less than 4, and also containing at least one of the metals or metal ions of silver, copper and zinc in an amount of 1 to 1,000 ppm. The composition may optionally also contain hydrogen peroxide.

Abstract: Environmentally friendly processes for prevention of qualitative deterioration and quantitative loss of plant matter and foodstuffs, during all stages of storage and handling, including pre- and post-harvest, pre- and post-planting, distribution and marketing involves the use of H2O2 compositions including Ag and at least one of Cu and Zn ions. The processes can also be used to prevent sprouting and rooting, and to promote fecundity of certain plant matter, and can also be used to eliminate or reduce quantities of harmful organisms and substances from soil, other growth media and substrates, equipment, materials water, workspaces and surfaces.
