Herbicide Composition
Field of the Invention
The invention relates to a herbicide composition, to a method of preparing the same and to a method of controlling the growth of plants using the composition.
Background to the Invention
Many herbicides have been developed over the years but in many cases these have deleterious effects. For example, they may poison crops, adversely impact other plants or animals, and/or introduce toxins into the environment or soil. In addition, many herbicides presently on the market are highly toxic to humans.
Most chemical herbicides are dangerous to humans. Because of the widespread concern of the deleterious side effects of many herbicides, there is much concern as to the long-term use of complex and highly dangerous chemicals, especially when they enter into the food chain. Further, the use of toxic chemicals in production of foods prevents such foods from being marketed as organic products in a majority of countries.
Herbicides having low or no toxicity that can be used in the production of organic products and for home use is desirable in view of the growing demand for organic products. Notably, there is an increased shift toward organic food production and the desire to protect our living environment from toxic materials.
In light of the above, there is a continuing need for more natural, safer, cost effective, and environmentally-friendly herbicides having adequate efficiency and efficacy that can be formulated to provide a herbicide suitable for use in, for example, organic agricultural production in compliance with regulatory requirements.
Summary of the Invention
The present invention provides a herbicide composition comprising:
(i) naturally fermented vinegar providing a carboxylic acid content in the composition ranging from 1 to 25% w/w;
(ii) sodium chloride in an amount ranging from 5 to 25 % w/w; and
(iii) phosphatidycholine in an amount ranging from 0.5 to 10 % w/w;
with the proviso the composition does not comprise a source of naturally occurring phosphatidycholine.
The present invention also provides a method of producing a herbicide composition, said method comprising mixing together:
(i) naturally fermented vinegar in an amount to provide a carboxylic acid content in the composition ranging from 1 to 25% w/w;
(ii) sodium chloride in an amount ranging from 5 to 25 % w/w; and
(iii) phosphatidycholine in an amount ranging from 0.5 to 10 % w/w;
with the proviso the phosphatidylcholine is not provided by using a source of naturally occurring phosphatidycholine.
The present invention further provides a method for controlling the growth of a plant which comprises applying a herbicide composition according to the invention to the plant.
Surprisingly, it has now been found that naturally fermented vinegar, sodium chloride and phosphatidylcholine can be formulated to provide for an effective and efficient herbicide composition.
Without wishing to be limited by theory, it is believed the naturally fermented vinegar, sodium chloride and phosphatidycholine act synergistically to provide a formulation having superior uptake into plants.
- 2a
It is known that acetic acid based compositions can be used as herbicides. However, it is also known that the uptake into plants of such conventional compositions is relatively poor and they require acid concentrations of 20 % w/w or more to be practically effective as a herbicide.
Herbicide compositions according to the present invention demonstrate improved uptake into plants relative to conventional acetic acid based herbicide compositions. Without wishing to be limited by theory, it is believed compositions according to the invention facilitate transmission of the sodium chloride and carboxylic acid from the
H:\sxn\lnteoven\NRPortbl\DCC\SXN\15501993_1.docx-10/08/2017
-3
naturally fermented vinegar through the plant cuticle and into the underlying plant cells to invoke a desiccant effect that damages or kills plant growth.
Herbicide compositions according to the invention advantageously demonstrate efficacy when the carboxylic acid content of the composition from the naturally fermented vinegar is as low as 1 % w/w.
Detailed Description of the Invention
As used herein the term "herbicide" is intended to mean a composition that controls or modifies the growth of plants. The term "herbicidally effective amount" means the quantity of one or more components in the compositions that is capable of producing a controlling or modifying effect on the growth of plants. Controlling or modifying effects include all deviation from natural development, for example: killing, retardation, leaf burn, albinism, dwarfing and the like. The term "plants" refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, foliage, and fruits.
Compositions according to the invention comprise naturally fermented vinegar. Those skilled in the art will appreciate that naturally fermented vinegar is not merely an aqueous solution of acetic acid.
Naturally fermented vinegar is a solution derived from the fermentation of sugar in to alcohol which is then fermented by bacteria into a carboxylic acid such as acetic acid. While naturally fermented vinegar may contain acetic acid, it will also contain other components, including bacteria, derived from the fermentation process.
A variety of materials can be used to provide sugar that is fermented to produce naturally fermented vinegar. In one embodiment, sugar cane is used to provide the source of sugar that is fermented to produce the naturally fermented vinegar.
Naturally fermented vinegar will generally be produced so as to have a carboxylic acid (e.g. actetic acid) content ranging from about 2-25 % w/w.
Compositions according to the invention comprise sodium chloride.
In one embodiment, the sodium chloride is provided in the form of sea salt. Those skilled in the art will appreciate that sea salt is not merely sodium chloride.
Sea salt is derived from sea water and in addition to sodium chloride will contain trace minerals such as sulphate, magnesium, calcium, potassium, bicarbonate, bromide, borate, strontium, and fluoride.
Without wishing to be limited by theory, the presence of such trace minerals is believed to also facilitate the uptake of the herbicide composition into plants.
Compositions according to the invention also comprise phosphatidylcholine. Phosphatidycholines are a class of phospholipids that incorporate choline as a head group. Phosphatidylcholines can be readily obtained from a variety of sources such as egg yolks and soybeans.
However, it will be appreciated the present invention is not intended to embrace using in the compositions of the invention merely a source of natural occurring phosphatidycholine (e.g. egg yolk or soybean product). Rather, compositions according to the invention comprise phosphatidylcholine per se, such as phosphatidylcholine extracted from such natural sources.
In one embodiment, the phosphatidylcholine is egg yolk extracted phosphatidylcholine.
Owing to the nature of the components used in the compositions according to the invention, the compositions can advantageously be certified as being organic.
In one embodiment, the herbicide composition according to the invention is an organic certifiable herbicide composition.
In one embodiment, the herbicide composition is in the form of an emulsion.
In another embodiment, the naturally fermented vinegar is present in the form of a chelate.
- 4a
The naturally fermented vinegar is used in a herbicidally effective amount.
The naturally fermented vinegar may comprise about 1, 2, 5, 8, 10, 15, 20 or 25
% w/w of carboxylic acid.
In one embodiment, the naturally fermented vinegar is present in an amount that provides the composition with a carboxylic acid content of about 1, 2, 5, 8 or 10 or 20% w/w.
In one particular form of the invention the naturally fermented vinegar is present in an amount that provides the composition with a carboxylic acid content of about 8 or 10% w/w.
In another embodiment, the naturally fermented vinegar is present in an amount ranging from about 2, 5, 8 or 10 or 20% w/w.
Without wishing to be limited by theory, the naturally fermented vinegar is believed to function as an active agent in the herbicide. The naturally fermented vinegar is believed to work as an active agent together with at least one other component, such as the sodium chloride (sea salt) in the herbicide to enhance the herbicidal activity of that component and/or the herbicide. The naturally fermented vinegar is generally present at a concentration in the herbicide that is synergistic insofar as it enhances the herbicidal activity of another component such as the sodium chloride (sea salt). The effective concentration of the naturally fermented vinegar in the herbicide is generally less than that would otherwise be required in the absence of the sodium chloride (sea salt).
The naturally fermented vinegar is generally present in an amount that allows it to function as a desiccant upon contact of the composition with a plant.
The sodium chloride may be selected from: sea salt, rock salt, magnesium salts or salts derive from other sources.
The sodium chloride is used in a herbicidally effective amount.
The sodium chloride will generally be present in an amount of about 5, 10, 15, 20 or 25% w/w of the herbicide composition.
In one embodiment, the sodium chloride is present in an amount of about 5-15% or 12-20% of the herbicide composition.
Without wishing to be limited by theory, the sodium chloride is believed to function as an active agent in the herbicide composition. The sodium chloride is believed to work as an active agent together with at least one other component, such as the naturally fermented vinegar in the composition to enhance the herbicidal activity of that component and/or the herbicide.
The effective concentration of the sodium chloride in the herbicide is generally less than would otherwise be required in the absence of the naturally fermented vinegar.
The sodium chloride is also believed to function as a preservative to maintain the integrity of other components in the herbicide. In that regard, the sodium chloride is believed ability to at least minimises and preferably eliminates micro-organism growth and thus has a preservative effect.
Phosphatidycholine used in the composition is believed to improve the activity of the sodium chloride and naturally fermented vinegar.
Phosphaidycholine will generally be present in an amount of about 0.001-10, or 0.001-5, 0.005-5 or 0.5-5 % w/w of the herbicidal composition.
The herbicide may further comprise a surfactant.
Preferably the surfactant is organic.
Preferably, the surfactant is also adapted to function as the metal binding agent i.e. a single component can provide both the metal binding agent and the surfactant.
The surfactant may function as an emulsifier.
Preferably, the surfactant comprises or is derived from oil, such as palm oil or other organic oils derived from vegetable extracts.
Preferably, the surfactant may be comprised of lauryl dimethyl amine oxide, polyoxypropylene, octylphenol ethoxylates (5EO to 12EO), nonylphenol ethoxylates, polyoxyethylene block copolymers alcohol ethoxylate, polyethoxylated castor oil (POE from 16-40), polyoxyethylenesorbitans, polyoxyethylenesorbitan monooleate, anionic surfactants such as salts of fatty acids, alkyl sulphates, alkyl ether sulphonates and alkyl aryl sulphonates, nonionic surfactants such as nonylphenolethoxylate

surfactants, esters of monoglycerides of fatty acids that are made from natural fatty acids, glycerol and an organic acid such as acetic, citric, lactic or tartaric where the fatty acid component may be from a vegetable or animal source, nonylphenol polyoxyethylene 10 phosphate ester, alkylether mono & di-phosphate ester, 2,6,8 trimethyl-4-nonyl ether ethoxylate, poly(oxy-1,2-ethanediyl), alpha(nonylphenyl omega-hydroxy) and combinations thereof.
Preferably, the surfactant is present in an amount sufficient to render the herbicidally active component(s) in the composition miscible in the water or another hydrophilic solvent.
Preferably, the surfactant comprises about 0.1-5% of the herbicide. In one particular form of the invention, the surfactant comprises about 0.5% of the herbicide.
The herbicide may further comprise iodine.
The pH of the herbicide will generally be acidic. In one form of the present invention the pH of the herbicide is about 2-6, 2-5.5, 3-5 or 2, 3, 4, 5 or 6.
When the pH of the herbicide requires adjustment it may be raised or lowered by including a pH modifier in the herbicide composition. Examples of pH modifiers that can be selected for use in connection with the invention include, without limitation, potassium carbonate, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium hydroxide, potassium carbonate, calcium hydroxide and calcium carbonate.
The remainder of the herbicide composition will generally comprise water.
Preferably, the components of the composition are at least partially dissolved in the water.
The herbicide may be an oil/water emulsion.
The herbicide may further comprise a wetting agent effective to improve the wetting properties, and possibly also the penetration properties, of the herbicide. When a
H:\sxn\lnteoven\NRPortbl\DCC\SXN\15501993_1.docx-10/08/2017
-8
wetting agent is included in a herbicide of the invention, the composition sprayed on the weeds or other vegetation can be applied at a lower rate to achieve an equivalent result because the wetting agent causes each droplet of the composition to spread over a greater surface area of the plant.
Preferably, the wetting agent is organic.
Examples of wetting agents for the present invention include nonylphenol ethoxylate, octylphenol ethoxylate, dodecyl sulfate and anionic, cationic and nonionic (including silicone based) surfactants and methylated seed oil. For organic formulations, the wetting agent may be any agent certified by a regulatory authority such as the EPA see for example wetting agents listed in Table 4.
Preferably, the wetting agent comprises about 0.05-15%, 0.5-10% or 2-8% w/w% of the herbicide.
One or more other components may optionally be included in the herbicides of the invention in order to provide aesthetic or other beneficial properties thereto. Such optional ingredients are, for example, antimicrobial agents, additional preservatives, deodorizers, colouring agents, fragrances, additional emulsifiers, additional solubilizers, corrosion inhibitors and additional solvents. Preferably, the other components are also organic.
By way of example, optional ingredients that can be incorporated include the following: an antimicrobial, such as, for example, phenolic compounds such as ophenylphenol and o-benzyl[p-chlorophenol]; quaternary ammonium compounds such as alkyldimethylbenzylammonium chloride, octyldecyldimethylammonium chloride, dioctyldimethylammonium chloride, didecyldimethylammonium chloride and alkyldimethylbenzylammonium saccharinate; a deodorizer, such as, for example, N alkyl-N-ethylmorpholinium ethyl sulfate.
The herbicide composition can be prepared by adding component to water or some other hydrophilic solvent. Thus, the present invention also provides a method of producing a herbicide composition, said method comprising mixing together:
H:\sxn\lnteoven\NRPortbl\DCC\SXN\15501993_1.docx-10/08/2017

(i) naturally fermented vinegar;
(ii) sodium chloride; and
(iii) phosphatidylcholine.
The method may also include the addition of water during or after the other components have been mixed.
The sodium chloride and the phosphatidycholine may be combined togetherfirst and then the naturally fermented vinegar is added.
The herbicide may be an emulsion. In that regard, the method mayfurther comprise a step of adding a surfactant. The surfactant may be added prior to the other components.
The method may comprise the step of mixing after the addition of each component.
Preferably, the method further comprises the resting the herbicide prior to use.
It will be appreciated that the herbicide of the present invention can be formulated in a final or ready to use ("RTU") format or as a concentrate that an end user can use to prepare a RTU formulation by diluting the concentrate with water or another hydrophilic solvent.
Thus, the herbicides of the present invention can be packaged as ready-to-use herbicides, or can be packaged as herbicide concentrate formulations. Where an inventive herbicide is to be used in a relatively small quantity, such as for home uses, the herbicide can be packaged in a conventional ready-to-use dispensing system. In contrast, when the end user is a farmer or professional applicator who intends to use the herbicide on a large area, it would be more desirable to provide a herbicide concentrate formulation that is ready for dilution.
In contrast, the amount of the other components such as the phosphatidylcholine, sodium chloride and naturally fermented vinegar that would desirably be included in
H:\sxn\lnteoven\NRPortbl\DCC\SXN\15501993_1.docx-10/08/2017
-10
the herbicide can depend upon the volume and the initial pH of the rest of the formulation.
The invention also includes a method for controlling the growth of a plant which comprises applying the herbicide composition to the plant.
The herbicide may be applied by conventional means such as spaying.
The control effected by application of the herbicide to a plant will typically cause the the plant, where contacted, to wilt, bleach, or brown, which results in necrosis of the leaf ("burn down") and death of the plant. That effect may occur within 3-5 days after application with the plant displaying visible effects of the herbicide 2 days after application of the herbicide.
The process of applying the herbicide to the plant may comprise applying the herbicide to at least 60, 70, 80, 90 or 99% of the surface area of the plant.

Phosphatidylcholine is used and can be obtained from commercial sources or prepared, if required.
Surfactant is used and can be obtained from commercial sources or prepared if required.
Example 2 -Preparation of herbicide
Method/materials
Add 50% of the total water required to a container of sufficient size.
Connect the inlet of a chemical resistant transfer pump to the base of the container and the outlet of the pump to a port at the top of the container to allow for the pump to cycle the contents of the container.
Connect another pump, such as a venturi or chemical dosing pump, preferably a peristaltic pump to the pump intake line at the closest appropriate point of the container.
Turn on the cycling pump to commence circulation.
(Optionally) add the surfactant to the system via the pump and run the cycling pump until three times the volume of the fluid in the system is cycled. The volume of cycled liquid can be measured by a flow meter connected to the outlet of the pump.
Add the sodium chloride (e.g. sea salt) to the system via pump and cycle a further two times the volume of the fluid in the system.
Add the reactive agents (e.g. Phosphatidylcholine) and cycle two times the volume of the fluid in the system.
Add the Naturally fermented vinegar and cycle four times the volume of the fluid in the system. The mixed formulation is then rested for a minimum of eight hours before dispensing for use.
Example 3 - Field trials
A herbicide composition according to the invention was prepared by mixing 8 %w/w naturally fermented vinegar (having a 20 %w/w carboxylic acid content), 12 % sea salt, 2 % w/w egg yolk phosphatidylcholine up to 100 % w/w with water.
The herbicide composition was applied once by spray to flat weeds. After 2 days 99 % over 1 m2 of the weeds were killed.
The herbicide composition was applied once by spray to thistles that were about 200 mm high and 30 plants to 1 m2. After 2 days 94 % of the thistles were killed.
