Abstract
The present invention is in respect of a natural herbicide that utilizes acetic acid, i.e. vinegar, to kill weeds. The acetic acid is combined with a natural surfactant, such as yucca extract.
Description
HERBICIDAL COMPOSITION COMPRISING ACETIC ACID AND A
NATURAL 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.
SUMMARY OF THE INVENTION
The present invention therefore provides a herbicidal composition comprising a solution of vinegar/acetic acid and a natural food grade surfactant, such as yucca extract.
Preferably in the composition of the present invention, the acetic acid is an aqueous solution of 15-25% acetic acid.
More preferably, the vinegar/acetic acid solution is about 19-21 % acetic acid.
The surfactant may comprise about 0.1-3% of said composition.
Preferably, the surfactant comprises about 0.2% of said composition.
In a preferred embodiment, the composition of the present invention comprises an aqueous solution of vinegar at about 20% acetic acid, and about 0.2%
surfactant.
DETAILED DESCRIPTION
The applicant has discovered that vinegar/acetic acid, at a strength of between about 15% to about 25%, mixed with about 0.1 to about 3% of a surfactant will function as an effective herbicide.
A preferred formulation is 20% acetic acid, mixed with 0.2% yucca as a surfactant. A preferred form of yucca is yucca extract in ethanol, available from Desert King International under the trademark Yucca Ag-Aide 50TH
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 surfactants, such as TKOTM
(an orange derivative) can be used instead of yucca, if desired with good effect.
The applicant has found that a 20% acetic acid, 0.2% yucca, water mixture will provide a sprayable herbicide with a coverage potential of about 700 sq. feet per litre. If it is desired to use, e.g. TKOTM, about 2% should be added instead of yucca.
The mixture of the present invention, i.e., 20% acetic acid, with a surfactant, is very effective to kill unwanted vegetation.
