Definitions
- the present invention relates to herbicidal compositions.
- a novel herbicidal composition which is composed of edible material and hence can be safely applied to vegetation without risk of harm to animals, including humans.
- composition of the invention can be formulated to effectively kill all vegetative growth, including normally hard-to-kill weeds as well as grasses, in a rapid period of time.
- the composition may be formulated as a selective herbicide, for example, to kill common lawn weeds, while leaving the grass unaffected.
- the composition of the invention also is useful as a defoliant.
- composition of the invention comprises a synergistic combination of acetic acid and another organic acid, preferably citric acid.
- the acetic acid component conveniently is provided by domestic white vinegar while the citric acid is conveniently provided by lemon juice or the juice of another citrus fruit.
- the composition of the invention may be formulated as a concentrate comprising glacial acetic acid and citric acid or other organic acid, such as ascorbic acid, dissolved in water, which then may be diluted for use.
- acetic acid alone exhibits some effect as a herbicide, the presence of small quantities of citric acid considerably enhances the effect.
- Citric acid at high concentrations exhibits some effect as a herbicide.
- the weight ratio of acetic acid to citric acid in the composition may vary from about 10:1 to about 1:1, preferably about 4:1 to about 2:1.
- the composition in use may contain up to about 10 wt% of acetic acid, preferably about 1 to about 5 wt.%.
- the composition in use may contain about 0.25 to about 2.5 wt% citric acid.
- a particularly-useful composition according to the invention comprises about 2 parts vinegar and about 1 part of lemon juice or other citrus fruit juice. This composition is diluted with water to provide the composition ready for use. The degree of dilution of the composition determines whether the herbicidal composition will kill all vegetation and whether it is selective.
- composition which has been found useful as a total vegetation kill composition comprises: 500 mis of vinegar 250 is of lemon juice
- composition 750 to 1250 mis of water If the dilution is increased to about 2300 mis of water, the composition becomes a selective herbicide. Too much dilution results in no herbicidal properties. For example, dilution by 5000 mis of water produces no herbicidal response.
- Another useful composition comprises: 10 wt.% glacial acetic acid
- One useful formulation of concentrate comprises: 160 g acetic acid 40 g citric acid 800 ml water This concentrate then is diluted for use to the desired strength.
- the composition of the invention is composed of natural and edible components, namely acetic acid and citric acid or other organic acid, and hence, not only is efficacious as a herbicide, either for total or selective kill of vegetation, but is safe to use. In contrast, most herbicides require chemical synthesis and exhibit toxic side effects on animals.
- the present invention relates to a novel herbicidal composition
- a novel herbicidal composition comprising synergistic combinations of acetic acid and citric acid, most conveniently provided by vinegar and lemon juice, which are diluted with water to provide the desired herbicidal properties. Modifications are possible within the scope of this invention.
