Abstract
A herbicidal composition is described comprising an aqueous solution of from 9% to less than 15% by mass acetic acid. An effective quantity of a natural adjuvant surfactant selected from the group consisting of yucca, sugar beet juice, and natural insecticidal soap is also provided as a part of the composition.
Description
HERBICIDAL COMPOSITION COMPRISING ACETIC ACID AND A
NATURAL ADJUVANT SURFACTANT
TECHNICAL FIELD
The present invention relates to the field of herbicides.
The present invention is in respect of a natural herbicide, that utilizes acetic acid, i.e.
vinegar, to kill weeds.
BACKGROUND OF THE INVENTION
There are many weed killers known in the art. Many chemical weed killers have been banned because of perceived harmful side effects, and the effects of new federal and provincial laws. It is an object of the present invention, then, to provide a weed killing or herbicidal composition that is environmentally acceptable and non-toxic, and which is safe for consumer use, and subject to minimal regulation.
SUMMARY OF THE INVENTION
In a broad aspect, the present invention provides:
(1) A herbicidal composition comprising an aqueous solution of from 9% to less than 15% by mass acetic acid, and an effective quantity of a natural adjuvant surfactant selected from the group consisting of yucca, sugar beet juice, and natural insecticidal soap.

SUMMARY OF THE INVENTION
In a broad aspect, the present invention provides:
(1) A herbicidal composition comprising an aqueous solution of from 9% to less than 15% by mass acetic acid, and an effective quantity of a natural adjuvant surfactant selected from the group consisting of yucca, sugar beet juice, and natural insecticidal soap.
(2) The composition of (1), wherein said acetic acid solution is 9 to 11%
acetic acid by mass.
acetic acid by mass.
(3) The composition of (1) or (2), wherein said surfactant comprises 0.1 to 3% by mass of said composition.
(4) The composition of (1), (2) or (3), wherein said surfactant comprises 0.1 to 1% by mass of said composition.
(5) The composition of any one of (1) to (4), wherein said composition comprises an aqueous solution of about 10% acetic acid by mass, and 0.2%
surfactant, by mass.
surfactant, by mass.
(6) The composition of any one of (1) to (5), wherein said surfactant is sugar beet juice or yucca.
(7) The composition of any one of (1) to (5), wherein said surfactant is natural insecticidal soap.
(8) The composition of (7), wherein said soap contains 2% potassium salts of fatty acids.
DETAILED DESCRIPTION
It has been discovered that vinegar/acetic acid, at a strength of between about 9% to less than 15%, mixed with about 0.1 to about 3% of a natural adjuvant surfactant will function as an effective herbicide.
A preferred formulation is 10% acetic acid, mixed with 0.2% yucca as a natural adjuvant surfactant. A preferred form of yucca is yucca extract in ethanol, available from Desert King International under the trademark Yucca Ag-Aide 50J.
The yucca functions as a surfactant, and helps the acetic acid to stick to the leaves of plants. The acetic acid then kills the plant. Other natural adjuvant surfactants can be used, if desired, with good effect.
The mixture of the present invention, i.e., 10% acetic acid, with a natural adjuvant surfactant, is very effective to kill unwanted vegetation growing in cracks, gaps and the like. Accordingly, it is very effective as a cleaner for use on concrete, stone, and interlocking paves, to keep weeds from growing.
The herbicide of the present invention consists of a vinegar (10%) (all percentages herein are by mass) plus an organic plant extract (0.2%) as a wetting agent.
White vinegar is an aged and filtered product obtained from the acetous fermentation of diluted distilled ethanol of natural origin. The herbicide of the present invention is a totally organic product.
It will be understood that the present invention is a refinement and improvement on the invention described and claimed in applicant's Canadian Patent No. 2,732,386.
In that patent, a herbicidal composition is described having an acetic acid composition of 15 to 25%. This strength of acetic acid yielded greatly improved results over known 5%
acetic acid compositions.
The applicant has discovered, however, that acetic acid strength under 15%, to as low as

In that patent, a herbicidal composition is described having an acetic acid composition of 15 to 25%. This strength of acetic acid yielded greatly improved results over known 5%
acetic acid compositions.
The applicant has discovered, however, that acetic acid strength under 15%, to as low as
9% will provide results comparable to the use of 15% acetic acid. The applicant has particularly discovered that a composition of 10% acetic acid provides an excellent herbicide. This is important because solutions of 10% acetic acid are considered safe for consumers, i.e., homeowners to use, and use is subject to minimal regulation.
Therefore, the present invention provides the first effective acetic acid based herbicide for homeowner use.
