The present invention relates to methods of pest control employing clear, stable, water-based microemulsion formulations, compositions and methods comprising one or more anionic surfactants, one or more acylglycerol derived emulsifiers, a water-soluble organic cosolvent, and optionally fatty acids and/or salts thereof.
While the first recorded use of chemicals to control pests dates back to 2500 BC, only in the last 60 years has chemical control has been widely used. Early pesticides included hellebore to control body lice, nicotine to control aphids, and pyrethrin to control a wide variety of insects. Lead arsenate was first used in 1892 as an orchard spray, while at the same time it was discovered that a mixture of lime and copper sulphate (Bordeaux mixture) controlled downy mildew, a fungal disease of grapes. Many of the more recent pesticides have been developed to target specific biochemical reactions within the target organism, e.g. an enzyme necessary for photosynthesis within a plant or a hormone required for normal development in an insect.
Recently, there has been increased research into the deleterious effects of chemical pesticides, with concomitant efforts to develop safer alternatives to current commercial pesticides. Some of this research has focused on the use of natural products, such as combinations of chemicals obtained from plants, such as essential oils.
In general, synthetic chemical pesticides and natural pesticides are applied in particular formulations that facilitate their use against pests in the field. For example, hydrophobic pesticidal compounds, such as many agrochemicals and plant essential oils are poorly soluble in water, but have been used in formulations, such as emulsions, that permitted admixture with water to form a spray. However, in general, these formulations have simply been employed to facilitate application of the pesticide directly to the pests or to the surfaces or environments inhabited by the pests.
Microemulsions are uniform and thermodynamically stable liquid mixtures of oil, water and one or more surfactant, in which the dispersed phase size range is roughly on the order of 5 to 100 nm in diameter. A microemulsion forms spontaneously upon mixing the components of the formulation; this is in contrast to the high-shear conditions required for the formation of a typical emulsion. The surfactant system is necessary to produce an ultra-low interfacial tension between the water and oil phases, thereby lowering the energy required to produce the high surface area required for a microemulsion. Because the surfactant component is a wetting agent that lowers the surface tension of liquid, microemulsions tend to consist of a mixture that can be spread easier than other mixtures and thus provide greater surface area. Perhaps for this reason, considerable attertion has been directed toward microemulsion-based pesticidal formulations, and microemulsion formulations appear to be an emerging standard for the formulation of hydrophobic pesticides in water-based carriers.
In addition, suspension concentrates, dispersions of sparingly soluble active ingredients in water or in organic solvents, are also employed in conjunction with pesticidal compositions. Suspension concentrate pesticidal compositions are concentrated suspensions of water-insoluble pesticides, frequently containing 10% to 80% by weight of pesticides, and can provide a method of handling relatively water-insoluble pesticides in an aqueous medium. In general, it can be desirable to formulate pesticides in suspension concentrates due to the advantage of not requiring the use of organic solvents, often present in emulsifiable concentrates. These formulations also include suspensions of microencapsulated or nanoencapsulated pesticides for use as emulsifiable or suspendable pesticide concentrates.
Furthermore, pesticides can also take the form of suspo-emulsions, also known as suspension emulsions, which are mixtures of suspensions and emulsions. These formulations are popular for combining several types of compounds into a single formulation, with stabilization through the choice of inert components and process control parameters.
Efforts to improve pesticides have been mainly directed toward discovering new compounds that may act as active ingredients of the pesticide. To date, however, attertion has not been focused on the optimization of formulations specifically as a route to improve the aesthetics, stability, and activity of pesticidal formulations.
Unless otherwise noted, terms are to be understood according to conventional usage by those of ordinary skill in the relevant art.
As used herein, “oil” shall refer to any homogenous substance that is not miscible with water and exists as a liquid below 35° C. Oils may refer to pure compounds or mixtures of two or more compounds, including solutions of solid, liquid, or gaseous compounds in an oil to make a homogenous, non-water-miscible solution.
The present disclosure relates to emulsion-based formulations of pesticides, specifically pesticidal blends of essential oils and other ingredients, that have been found to enhance the aesthetics, stability, and activity of the pesticidal formulations. Surprisingly, the addition of the surfactant, emulsifier, and cosolvent to water in the correct proportions allows for the production of colorless, transparent oil-in-water microemulsions (“OWM”) capable of emulsifying water-immiscible oils and solids with poor aqueous solubility to a significant extert without becoming turbid while additionally retaining low viscosity.
Of additional interest are concentrates containing little or no water that may be diluted through the addition of water to form a clear, colorless OWM. As used herein, “concentrate” shall refer to any formulation that is intended to be mixed with water in a ratio of 2:1 to 100:1 of formulation to water to provide an emulsion or suspension of a pesticide for application.
As used herein, “pests” can mean any organism whose existence it can be desirable to control. Pests can include, for example, bacteria, cestodes, fungi, insects, nematodes, parasites, plants, and the like. “Pesticidal” can mean, for example, antibacterial, antifungal, antiparasitic, herbicidal, insecticidal, and the like.
As used herein, the term “pest control” shall refer to having a repellant effect, a pesticidal effect, or both. “Repellant effect” is an effect wherein more pests are repelled away from a host or area that has been treated with the composition than a control host or area that has not been treated with the composition. “Pesticidal effect” is an effect wherein treatment with a composition causes at least about 1% of the pests to die. In this regard, an LC1 to LC100 (lethal concentration) or an LD1 to LD100 (lethal dose) of a composition will cause a pesticidal effect. In some embodiments, the pesticidal effect is an effect wherein treatment with a composition causes at least about 5% of the exposed pests to die. In some embodiments, the pesticidal effect is an effect wherein treatment with a composition causes at least about 10% of the exposed pests to die. In some embodiments, the pesticidal effect is an effect wherein treatment with a composition causes at least about 25% of the pests to die. In some embodiments the pesticidal effect is an effect wherein treatment with a composition causes at least about 50% of the exposed pests to die. In some embodiments the pesticidal effect is an effect wherein treatment with a composition causes at least about 75% of the exposed pests to die. In some embodiments the pesticidal effect is an effect wherein treatment with a composition causes at least about 90% of the exposed pests to die.
The production of clear, colorless or nearly colorless microemulsions containing herbicidal, insecticidal, fungicidal, nematocidal, bactericidal, algicidal, or other pesticidal or pest repellent compounds or mixtures is of significant commercial interest. For example, such water-based, transparent formulations are appealing because they connote safety, purity, and spontaneity of use that are not typically associated with traditional synthetic pesticide chemistries. Additionally, the United States Environmental Protection Agency (“EPA”) and state regulatory agencies require that many pesticides have low volatile organic compound (“VOC”) contert; the current microemulsion formulations may be composed of compounds with no significant VOC contribution or are VOC-exempt, providing an additional commercial advantage. Furthermore, the microemulsion compositions can be produced containing only ingredients exempt from EPA registration by virtue of their appearance on the United States Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) 25(b) list or Class 4(a) inert ingredient list making the composition safe for use, and potertially eligible for classification as an organic pest control agent.
As used herein and known to one of skill in the art, the spectrum of various types of emulsions in terms of both water out and oil out, as well as size distribution of the emulsion are incorporated in the term “emulsions,” including microemulsions. Nevertheless, in particular embodiments of the present invention the formulation agents are not such as to form a microemulsion. Embodiments encompassing all or some formulations other than microemulsions are specifically contemplated.
As used herein, the term “RTU” means Ready-To-Use.
As used herein, “component of a composition” refers to a compound, or a subset of compounds included in a composition, e.g., the complete composition minus at least one compound.
As used herein, the term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system, i.e., the degree of precision required for a particular purpose, such as a pharmaceutical formulation. For example, “about” can mean within 1 or more than 1 standard deviations, per the practice in the art. Alternatively, “about” can mean a range of up to 20%, preferably up to 10%, more preferably up to 5%, and more preferably still up to 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, preferably within 5-fold, and more preferably within 2-fold, of a value.
As used herein, the term “substantially,” means at least about 70%, preferably at least about 80%, more preferably at least about 90%, and even more preferably at least about 99%, for example at least about 99.9%. In some embodiments, the term “substantially” can mean completely, or about 100%.

Geraniol is a monoterpenoid and an alcohol. It is the primary part of oil-of-rose and palmarosa oil. It is used in perfumes and as a flavoring. It is also produced by the scent glands of honeybees to help them mark nectar-bearing flowers and locate the entrances to their hives. In certain embodiments, where geraniol is employed, it may be mixed with 10%, 20%, 30%, or 40% or more nerol. Commercially obtained geraniol may be designated by the amount of geraniol it contains. For example, a 60/40 mixture of geraniol and nerol is termed “geraniol 60.” Nerol is a monoterpene (C10H18O), the Z-isomer of geraniol, which can be extracted from attar of roses, oil of orange blossoms and oil of lavender. Citral (3,7-dimethyl-2,6-octadienal or lemonal) is the generic name for the aldehyde form of nerol and geraniol, and can be obtained from lemon myrtle, Litsea cubeba, lemongrass, Lemon verbena, lemon balm, lemon, and orange. The E-isomer of citral is known as geranial or citral A. The Z-isomer is known as neral or citral B. Where an embodiment describes the use of any form of geraniol, other embodiments are specifically contemplated in which the geraniol is replaced by another form of geraniol (such as Geraniol Fine FCC or any geraniol/nerol mixture), nerol, geranial, neral, citral, or a mixture of any of these with each other or with any form of geraniol. Similarly, where an embodiment describes the use of any form of citral, other embodiments are specifically contemplated in which the citral is replaced by a form of geraniol (such as Geraniol Fine FCC or any geraniol/nerol mixture), nerol, geranial, neral, or a mixture of any of these with each other or with citral.
Vanillin (also known as methyl vanillin, vanillic aldehyde, vanillin, and 4-hydroxy-3-methoxybenzaldehyde) is the primary component of the extract of the vanilla bean. In addition to vanillin, natural vanilla extract also contains p-hydroxybenzaldehyde, vanillic acid, piperonal, and p-hydroxy-benzoic acid. Synthetic vanillin is used as a flavoring agent in foods, beverages, and pharmaceuticals. Where an embodiment describes the use of vanillin, other embodiments are specifically contemplated in which the vanillin is replaced by natural vanilla extract, p-hydroxybenzaldehyde, vanillic acid, piperonal, ethyl vanillin, or p-hydroxybenzoic acid, or a mixture of any of these with each other or with vanillin.
Methyl salicylate is found in betula oil. Methyl salicylate is a major component of oil of wintergreen and is sometimes referred to interchangeably with oil of wintergreen. It is a natural product of many species of plants, is the methyl ester of salicylic acid, and can be produced chemically from the condensation reaction of salicylic acid and methanol. Some of the plants producing it are called wintergreens, hence the common name. Methyl salicylate can be used by plants as a pheromone to warn other plants of pathogens (Shulaev, et al. (February 1997) Nature 385: 718-721). The release of methyl salicylate can also function as an exopheromone aid in the recruitment of beneficial insects to kill the herbivorous insects (James, et al. (August 2004) J. Chem. Ecol. 30(8): 1613-1628). Numerous plants produce methyl salicylate including species of the family Pyrolaceae and of the genera Gaultheria and Betula. It is noted that, where a given blend or formulation or other composition is disclosed herein as containing wintergreen oil, an alternative embodiment, containing methyl salicylate in place of wintergreen oil, is also contemplated. Likewise, where a blend or formulation of other composition includes methyl salicylate, an alternative embodiment, containing wintergreen oil, is also contemplated.
Wintergreen oil is oil from the shrub genus Gaultheria. Methyl salicylate, the main constituent of the oil, is not present in the plant until formed by enzymatic action from a glycoside within the leaves.
Thyme oil is a natural product that can be extracted from certain plants, including species from the Lamiaceae family; for example, thyme oil can be obtained from Thymus vulgaris (also known as, T. ilerdensis, T. aestivus, and T. velantianus), generally by distillation from the leafy tops and tender stems of the plant. Two commercial varieties of thyme oil are recognized, the ‘red,’ the crude distillate, which is deep orange in color, and the ‘white,’ which is colorless or pale yellow, which is the ‘red’ rectified by re-distilling. Thyme oil principally contains the phenols thymol and carvacrol, along with borneol, linalool, and cymene, and rosmarinic and ursolic acids. Where an embodiment describes the use of thyme oil white, other embodiments are specifically contemplated in which the thyme oil white is replaced by thyme oil red, thymol, carvacrol, borneol, linalool, cymene, rosmarinic acid, ursolic acid, or a mixture of any of these with each other or with thyme oil white. Particularly preferable are mixtures of thyme oil white and thyme oil red that contain 10% or less thyme oil red, more preferably 5% or less, and most preferably 1%.
Thymol is a monoterpene phenol derivative of cymene, C10H14O, isomeric with carvacrol, found in thyme oil, and extracted as a white crystalline substance. It is also known as 3-hydroxy-p-cymene, 5-methyl-2-(1-methyl ethyl)phenol, and 2-isopropyl-5-methylphenol. Where an embodiment describes the use of thymol, other embodiments are specifically contemplated in which the thymol is replaced by carvacrol, thyme oil white, thyme oil red, or a mixture of any of these with each other or with thyme oil white. Carvacrol, also known as 2-hydroxy-p-cymene, 2-methyl-5-(1-methylethyl)phenol, and 5-isopropyl-2-methylphenol, is a colorless liquid substance found in the oil of Origanum vulgare and other plants in family Lamiaceae.
Linalool is a naturally occurring terpene alcohol chemical found in many flowers and spice plants. It is also known as 3,7-dimethyloct-1,6-dien-3-ol. It has two stereoisomeric forms: (S)-(+)-linalool (known as licareol) and (R)-(−)-linalool (known as coriandrol). Linalool can be obtained as linalool coeur (a racemic mixture, CAS number 78-70-6), or in preferred derivative forms such as tetrahydrolinalool (the saturated form), ethyl linalool, linalyl acetate, and pseudo linalyl acetate (7-octen-2-ol, 2-methyl-6-methylene:acetate). Where an embodiment describes the use of any form of linalool, other embodiments are specifically contemplated in which the linalool is replaced by licareol, coriandrol, tetrahydrolinalool, ethyl linalool, linalyl acetate, pseudo linalyl acetate, or a mixture of any of these with each other or with any form of linalool.

In some embodiments, the active components for controlling pests and methods for preparing and using these compositions can include compounds that are generally regarded as safe (GRAS compounds). In some embodiments, the compositions can include compounds of a plant origin, such as plant essential oils or terpenes of plant essential oils.
As used herein, “water-immiscible phase” shall refer to the one or more solid or liquid substances that, together or separately, are neither fully miscible in a liquid state, nor sufficiently soluble to fully dissolve in water.
In various embodiments of the composition of the present invention, the ratio of surfactant to acylglycerol-derived emulsifier, on a by-weight basis, may vary from 1000:1 to 1:1000, preferably 100:1 to 1:100, more preferably, 20:1 to 1:20, and most preferably, 10:1 to 1:10.
In some embodiments, the ratio of the total mass percentage of the microemulsion system to active component may vary from 1000:1 to 1:2, preferably 100:1 to 2:3, more preferably 25:1 to 1:1, and most preferably, 10:1 to 1:1.
In some embodiments, the ratio of the total mass percentage of the microemulsion system to active component may vary from 10:1 to 1:20, preferably 5:1 to 1:15, and most preferably, 2:1 to 1:10.
In various embodiments of the composition of the present invention, the concentration of surfactant, on a by-weight basis as a percentage of the total weight of the formulation, may vary from 0.1% to 60%, preferably 0.1% to 30%, and most preferably 0.5% to 20%.
In various embodiments of the composition of the present invention, the concentration of acylglycerol-derived emulsifier, on a by-weight basis as a percentage of the total weight of the formulation, may vary from 0.1% to 50%, preferably 0.1% to 30%, and most preferably 0.5% to 20%.

Surprisingly, by blending certain compounds in certain relative amounts, the resulting composition demonstrates a repellant or pesticidal effect that exceeds the repellant or pesticidal effect of any component of the composition.
Surprisingly, by combining certain pest control chemicals, and compounds or blends of the present invention, pest control activity of the resulting compositions can be enhanced, i.e., a synergistic effect on pest control activity is achieved when a certain chemical or chemicals, and a certain compound or compounds are combined. In other words, the compositions including certain combinations of at least one chemical, and at least one compound or at least one blend of compounds can have an enhanced ability to control target pests, as compared to each of the chemicals or compounds taken alone.
Some fatty acids, particularly C8-C14 fatty acids, possess herbicidal activity on their own; additionally, some terpenes and plant essential oils are also herbicidal. The combination of a suitably herbicidal fatty acid, preferably a C8-C14 fatty acid, more preferably a C10-C12 fatty acid, used together with a plant essential oil and a terpene, produce a synergistic herbicidal effect.
Lauric acid (also known as dodecanoic acid, dodecylic acid, or laurostearic acid) is a saturated fatty acid with a 12-carbon atom chain and is found naturally in coconut oil, palm kernel oil, and laurel oil. Lauric acid is a low-odor white solid at room temperature. The combination of lauric acid and at least one essential oil or terpene appears to provide a synergistic increase in efficacy against various pests.
In certain embodiments of the present invention, “synergy” can refer to any substantial enhancement, in a combination of at least two ingredients, of a measurable effect, when compared with the effect of one active ingredient alone, or when compared with the effect of the complete combination minus at least one ingredient. Synergy is a specific feature of a combination of ingredients and is above any background level of enhancement that would be due solely to, e.g., additive effects of any random combination of ingredients. Effects include but are not limited to repellant effect of the composition; pesticidal effect of the composition; perturbation of a cell message or cell signal such as, e.g., calcium, cyclic-AMP, and the like; and diminution of activity or downstream effects of a molecular target.
As used herein, “synergy” and “synergistic effect” can refer to any substantial enhancement, in a composition of at least two compounds, of a measurable effect, e.g., an antiparasitic, pesticidal, or herbicidal effect, when compared with the effect of a component of the composition, e.g., one active compound alone, or the complete blend of compounds minus at least one com-pound. Synergy is a specific feature of a blend of compounds and is above any background level of enhancement that would be due solely to, e.g., additive effects of any random combination of ingredients.
In some embodiments, a substantial enhancement of a measurable effect can be expressed as a coefficient of synergy. A coefficient of synergy is an expression of a comparison between measured effects of a composition and measured effects of a comparison composition. The comparison composition can be a component of the composition. In some embodiments, the synergy coefficient can be adjusted for differences in concentration of the complete blend and the comparison composition.
Synergy coefficients can be calculated as follows. An activity ratio (R) can be calculated by dividing the % effect of the composition (AB) by the % effect of the comparison composition (Xn), as follows:
R=A
B
/X
n (Formula 1)
A concentration adjustment factor (F) can be calculated based on the concentration (Cn), i.e., % (wt/wt) or % (vol/vol), of the comparison composition in the composition, as follows:
F=100/Cn (Formula 2)
The synergy coefficient (S) can then be calculated by multiplying the activity ratio (R) and the concentration adjustment factor (F), as follows:
S=(R)(F) (Formula 3)
As such, the synergy coefficient (S) can also by calculated, as follows:
S=[(AB/Xn)(100)]/Cn (Formula 4)
In Formula 4, AB is expressed as % effect of the blend, Xn is expressed as % effect of the comparison composition (Xn), and Cn is expressed as % (wt/wt) or % (vol/vol) concentration of the comparison composition in the blend.
In some embodiments, a coefficient of synergy of about 1.1, 1.2, 1.3, 1.4, or 1.5 can be substantial and commercially desirable. In other embodiments, the coefficient of synergy can be from about 1.6 to about 5, including but not limited to about 1.8, 2.0, 2.5, 3.0, 3.5, 4.0, and 4.5. In other embodiments, the coefficient of synergy can be from about 5 to 50, including but not limited to about 10, 15, 20, 25, 30, 35, 40, and 45. In other embodiments, the coefficient of synergy can be from about 50 to about 500, or more, including but not limited to about 50, 75, 100, 125, 150, 200, 250, 300, 350, 400, and 450. Any coefficient of synergy above 500 is also contemplated within embodiments of the compositions.
Given that a broad range of synergies can be found in various embodiments described herein, it is expressly noted that a coefficient of synergy can be described as being “greater than” a given number and therefore not necessarily limited to being within the bounds of a range having a lower and an upper numerical limit. Likewise, in some embodiments described herein, certain low synergy coefficients, or lower ends of ranges, are expressly excluded. Accordingly, in some embodiments, synergy can be expressed as being “greater than” a given number that constitutes a lower limit of synergy for such an embodiment. For example, in some embodiments, the synergy coefficient is equal to or greater than 25; in such an embodiment, all synergy coefficients below 25, even though substantial, are expressly excluded.
In some embodiments, synergy or synergistic effect associated with a composition can be determined using calculations similar to those described in Colby, S. R., “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations,” Weeds, 1967 15:1, pp. 20-22, which is incorporated herein by reference. In this regard, the following formula can be used to express percent effect (E) of a composition including two compounds, Compound X and Compound Y:
E=X+Y−(X*Y/100) (Formula 5)
In Formula 5, X is the measured actual percent effect of Compound X in the composition, and Y is the measured actual percent effect of Compound Yin the composition. The expected percent effect (E) of the composition is then compared to a measured actual percent effect (A) of the composition. If the actual percent effect (A) that is measured differs from the expected percent effect (E) as calculated by the formula, then the difference is due to an interaction of the compounds. Thus, the composition has synergy (a positive interaction of the compounds) when A>E. Further, there is a negative interaction (antagonism) when A<E.
Formula 5 can be extended to account for any number of compounds in a composition; however it becomes more complex as it is expanded, as is illustrated by the following formula for a composition including three compounds, Compound X, Compound Y, and Compound Z:
E=X+Y+Z−((XY+XZ+YZ/100)+(X*Y*Z/1000) (Formula 6)
An easy-to-use formula that accommodates compositions with any number of compounds can be provided by modifying Formulas 5 and 6. Such a modification of the formula will now be described. When using Formulas 5 and 6, an untreated control value (untreated with composition or compound) is set at 100%, e.g., if the effect being measured is the amount of target insects killed, the control value would be set at 100% survival of the target insect. In this regard, if treatment with compound A results in 80% killing of the target insect, then the treatment with compound A can be said to result in a 20% survival, or 20% of the control value. The relationship between values expressed as a percent effect and values expressed as a percent-of-control are set forth in the following formulas, where E′ is the expected percent of control of the composition, Xn is the measured actual % effect of an individual compound (Compound Xn) of the composition, Xn′ is the percent of control of an individual compound of the composition, and A′ is the actual measured percent of control of the composition.
X=100−E′ (Formula 7)
X
n=100−Xn′ (Formula 8)
A=100−A′ (Formula 9)
By substituting the percent-of-control values for the percent effect values of Formulas 5 and 6, and making modifications to accommodate any number (n) of compounds, the following formula is provided for calculating the expected % of control (E′) of the composition:
According to Formula 10, the expected % of control (E′) for the composition is calculated by dividing the product of the measured actual % of control values (Xn′) for each compound of the composition by 100n-1. The expected % of control (E′) of the composition is then compared to the measured actual % of control (A′) of the composition. If the actual % of control (A′) that is measured differs from the expected % of control (E′) as calculated by Formula 10, then the difference is due to an interaction of the compounds. Thus, the composition has synergy (a positive interaction of the compounds) when A′<E′. Further, there is a negative interaction (antagonism) when A′>E′.
Compositions containing two or more compounds in certain ratios or relative amounts can be tested for a synergistic effect by comparing the pesticidal effect of a particular composition of compounds to the pesticidal effect of a component of the composition. Additional information related to making a synergy determination can be found in the examples set forth in this document. While synergy has been described in terms of a coefficient of synergy and in terms of the Colby synergy calculations, it is noted that synergy by other measures or determinations known in the art is, in some embodiments, also within the meaning of synergy as described and claimed herein.
