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 H 2 O 2 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.

Claims (11)

1. A method of treating soil or other plant growth media to kill pathogens in or on said soil or other plant growth media, comprising:

contacting said soil or other plant growth media with an amount sufficient of a hydrogen peroxide solution having a pH of less than 6, to kill pathogens in or on said soil or other plant growth media;

wherein said hydrogen peroxide solution contains metallic ions or silver and at least one of copper and zinc, said metallic ions being present in said hydrogen peroxide solution in an amount of 10 ppb to 5%;

wherein said hydrogen peroxide solution further contains at least one of peracetic, nitric, sulfuric and phosphoric acid, and

optionally one or more of salicylic acid, phosphonic acid, citric acid and glycerin.

2. The method of claim 1 , wherein said solution has a pH no greater than 4.

3. The method of claim 1 , wherein said solution contains both of said ions of copper and zinc.

4. The method of claim 1 , wherein said solution contains at least one of said salicylic acid, phosphoric acid and citric acid.

5. The method of claim 3 , wherein said solution contains at least one of said salicylic acid, phosphoric acid and citric acid.

6. The method of claim 1 , wherein said solution contains both phosphoric acid and peracetic acid.

7. The method of claim 3 , wherein said solution contains both phosphoric acid and peracetic acid.
