Abstract

A composition that includes ethylhexyl sulfate or a salt thereof, an alkylbenzenesulfonic acid or a salt thereof, and a carrier. The ethylhexyl sulfate, or salt thereof, and the alkylbenzenesulfonic acid, or salt thereof, are present in a weight ratio of at least about 1:2. The composition can be used for killing or inhibiting a microorganism or pathogen (e.g., bacteria, gram-negative bacteria, gram-positive bacteria, enteric bacteria, virus, fungus, mold, mildew or powdery mildew).

Claims

1. A method of killing or inhibiting a microorganism or a pathogen located on a surface of a plant, the method comprising contacting the microorganism or the pathogen with an effective amount of a composition comprising:

(a) ethylhexyl sulfate of the formula

2. The method of claim 1, wherein n has an average value of about 9 to about 11.

3. The method of claim 1, wherein the sodium hydroxide, potassium hydroxide, or combination thereof is present in ratio of less than about 1:

4, relative to the ethylhexyl sulfate, or salt thereof.

4. The method of claim 1, wherein the composition comprises:

(a) at least about 4 wt. % ethylhexyl sulfate, or salt thereof;

(b) at least about 6 wt. % dodecylbenzenesulfonic acid, or salt thereof;

(c) at least about 0.5 wt. % sodium hydroxide, and

(d) water.

5. The method of claim 1, wherein the microorganism or the pathogen is at least one of a bacteria, a virus, a fungus, a mold and a mildew.

6. The method of claim 1, wherein the microorganism or pathogen is at least one of a gram-negative bacteria, gram-positive bacteria and an enteric bacteria.

7. The method of claim 1, wherein the period of time effective to kill or inhibit the microorganism or the pathogen is less than about 30 seconds.

9. The method of claim 1, wherein the composition is formulated as a fluid liquid.

10. The method of claim 1, wherein the composition is formulated for application by spraying the composition.

11. The method of claim 1, wherein the composition optionally comprises a disinfectant selected from the group consisting of chlorine gas (Cl₂), ozone (O₃), lactic acid, ultraviolet light, peroxides, peracetic acid, potassium sorbate, lactic acid, and combinations thereof.

12. The method of claim 1, wherein the composition does not comprise chlorine dioxide.

13. The method of claim 1, wherein the contacting the microorganism or the pathogen comprises contacting an edible part of the plant.

14. The method of claim 1, wherein the contacting the microorganism or the pathogen comprises contacting the plant before harvesting.

15. The method of claim 1, wherein the contacting the microorganism or the pathogen comprises contacting the plant after harvesting.

16. The method of claim 1, wherein the microorganism or pathogen comprises at least one of:

bacteria,

gram-negative bacteria,

gram-positive bacteria,

enteric bacteria,

virus,

DNA virus,

reverse transcribing virus,

fungus,

rice blast fungus,

tree pathogen,

fruiting and flowering vegetables,

podded vegetables,

bulb and stem vegetables, and

root and tuberous vegetables.

18. The method of claim 1, wherein the plant is afflicted with, or at risk of, at least one of the following diseases or disorders:
