Abstract

The present invention is compositions and methods for improving seed germination rates or speed using a composition comprising at least one high valency silver ion. The compositions and methods of the present invention are effective in treating biofilms.

Claims

1. A method for improving the germination rate or speed of a seed, comprising contacting said seed with an agent comprising at least one form of high valency silver.

2. The method of claim 1 wherein said agent is an anti-biofilm agent.

3. The method of claim 2 wherein said biofilm is from a microorganism selected from the group consisting of Pseudomonas ssp., Xanthomonas ssp., Curtobacterium ssp., Fusarium ssp., Rhizoctonia spp., Pythium ssp., Phytophthora spp., Aspergillus ssp., and variants thereof.

4. The method of claim 1 further comprising contacting said seed with an at least one additional active agent.

5. The method of claim 4 wherein the active agent is selected from one or more agents comprising an antimicrobial agent, a fungicide, a preservative, a viricide, a parasiticide, an insecticide, a bactericide, a bacteristatic agent, a pesticide, and a chemical agent.

6. The method of claim 1 wherein said at least one form of high valency silver comprises an at least one form of stable soluble silver ion selected from the group consisting of Ag++ and Ag+++.

7. The method of claim 6 wherein said at least one form of a high valency silver comprises oxysilver nitrate, silver periodate, silver (II) biguanide, silver (III) biguanide, or combinations thereof.

8. The method of claim 1 wherein contacting the seed comprises contacting a soil or growth medium intended to receive the seed.

9. A composition for improving the germination rate or speed of a seed comprising a composition comprising at least one form of high valency silver.

10. The composition of claim 9 wherein the composition is a powder, or an aqueous suspension or solution of high valency silver ions.

11. The composition of claim 9 wherein the composition is a solution of high valency silver ions.

12. The composition of claim 10 wherein the composition includes silver periodate.

13. The composition of claim 9 wherein the composition comprises oxysilver nitrate, silver periodate, silver (II) biguanide, silver (III) biguanide, silver II oxide, or combinations thereof.

14. The composition of claim 9 further comprising at least one additional active agent.

15. The composition of claim 14 wherein the additional active agent is selected from the group consisting of an antimicrobial agent, a fungicide, a preservative, a viricide, a parasiticide, an insecticide, a bactericide, a bacteristatic agent, a pesticide, and a chemical agent.
