Patent Application
20230337663
An agricultural composition comprising farnesene is provided for controlling plant pathogens. Particularly, the agricultural composition is used to control powdery mildew and other fungi, as well as certain insects.
Plant crops are susceptible to disease causing pathogens, which when left uncontrolled may destroy crops, Pathogens typically include, but are not limited to, fungi, such as powdery mildew. Pathogens often proliferate due to agricultural practices and/or environmental factors, e.g., high temperature and humidity. Providing effective control of pathogens in home or commercial agricultural operations is desirable to ensure productivity.
Effective control of pathogens in an environmentally acceptable manner is also desirable. Environmentally friendly agricultural compositions that may control and/or treat and/or reduce and/or remove pathogen populations from plant crops and animals are desirable amongst consumers, who seek out foods that have been grown, cultivated or produced in an environmentally friendly manner, typically utilizing organic and/or biodegradable and/or human and animal safe products.
There remains a need to provide for new and improved agricultural compositions to control pathogen populations, and to control and/or treat disease caused by pathogens.
An agricultural composition is provided comprising at least one sesquiterpene.
The sesquiterpene can be farnesene, e.g., β-farnesene.
The farnesene can act as a fungicide, bactericide, insecticide, pesticide or a combination thereof. The farnesene may be a fungicide, e.g., that is effective against powdery white mildew. The farnesene can be a pesticide, e.g., that is effective against flies, aphids, mosquitos, and ants.
The composition may further include a detergent or surfactant, e.g.; an anionic surfactant, a cationic surfactant, and/or a nonionic surfactant.
The agricultural composition may be provided as a concentrate. The farnesene and a carrier, e.g., an oil, can be provided in concentrated form and diluted, e.g., with water, to provide the agricultural composition for application to plants.

The compositions of the various embodiments were precisely developed to prevent and control pest in powdery mildew in commercial and home gardens. The compositions of the various embodiments use an ecofriendly blend of nontoxic ingredients as well as an exclusive bug block technology. The compositions of the various embodiments comprise a blend of sesquiterpenes that is one of nature's most powerful pest repellents and found in many natural sources.
The compositions of the various embodiments are EPA registration exempt as a low risk pesticide and QR Code enabled linked to pesticide lab analysis to ensure consumers that the compositions of the various embodiments are pesticide free.
The compositions of the various embodiments are a breakthrough product developed under Project Hemp for Victory, which is operated by Hempyre Genetics of Oklahoma City, OK, the general contractor for Northwestern Oklahoma State University's industrial hemp pilot program. The program is the world's first advanced research project to acquire multiple varieties of Cannabis growing across the state of Oklahoma for research. Hempyre Genetics acquired over 100 varieties of industrial hemp growing wild and began growing each in a closed environment immediately. Upon planting multiple of the selected varieties of landrace Cannabis, it was noted that the different cultivars had various traits.
Selected varietals went through numerous tests for stress factors such as heat, cold, deprivation of nutrients, high and low humidity, root bounding, light deprivation and sensitivity changes. Signs of pests and other problems such as powdery white mildew were immediately observed. Regulations and restrictions set forth by the Oklahoma Department of Agriculture made it very difficult to combat these problems without the use of traditional pesticides and mildew control products.
It was observed that one specific variety of hemp from a remote location in Oklahoma was virtually unaffected by many of these problems that were becoming detrimental to all of the other cultivars. Upon the completion of the grow cycle and harvesting the mature plants, samples were sent off for analysis. This unique strain of hemp found in the wild on the plains of Oklahoma contained a unique terpene complex of six sesquiterpenes, commonly referred to as farnesene.
The term farnesene refers to a set of six closely related chemical compounds which all are sesquiterpenes. α-Farnesene and β-farnesene are isomers, differing by the location of one double bond α-Farnesene is 3,7,11-trimethyl-1,3,6,10-dodecatetraene and β-farnesene is 7,11-dimethyl-3-methylene-1,6,10-dodecatriene. The alpha form can exist as four stereoisomers that differ about the geometry of two of its three internal double bonds (the stereoisomers of the third internal double bond are identical). The beta isomer exists as two stereoisomers about the geometry of its central double bond. Two of the α-farnesene stereoisomers are reported to occur in nature. (E,E)-α-Farnesene is the most common isomer. It is found in the coating of apples, and other fruits, and it is responsible for the characteristic green apple odor. Its oxidation by air forms compounds that are damaging to the fruit. The oxidation products injure cell membranes which eventually causes cell death in the outermost cell layers of the fruit, resulting in a storage disorder known as scald. (Z,E)-α-Farnesene has been isolated from the oil of perilla. Both isomers are also insect semiochemicals they act as alarm pheromones in termites or food attractants for the apple tree pest, the codling moth. α-Farnesene is also the chief compound contributing to the scent of gardenia, making up ˜65% of the headspace constituents. β-Farnesene has one naturally occurring isomer. The E isomer is a constituent of various essential oils. It is also released by aphids as an alarm pheromone upon death to warn away other aphids. Several plants, including potato species, have been shown. to synthesize this pheromone as a natural insect repellent. The farnesene can act as a fungicide, bactericide, insecticide, pesticide or a combination thereof. The farnesene may be a fungicide, e.g., that is effective against powdery white mildew. The farnesene can be a pesticide, e.g., that is effective against flies, aphids, mosquitos, and ants.
After attempting to utilize over 40 different methodologies, an ecofriendly product was developed containing an ecofriendly blend of ingredients along with the same ratio of farnesene components observed in the hemp observed earlier to be resistant to pests. Not only was a turnaround in the number of pests observed after treatment, but also a complete eradication of powdery white mildew. Powdery white mildew is a very common problem to indoor gardens around the world, especially in regions of high humidity. It was observed that the plant responded positively to application of the composition after the first application, and within 24 hours drooping and yellowing in the leaves diminished, with the leaves beginning to reach upward and regain color. The varieties most affected by the powdery white mildew were 95% free of any visible mildew within 24 hours, and within 48 hours began regaining lost color and turning green where the mildew was affecting the leaf.
The compositions of the embodiments have numerous applications from small indoor gardens to agronomic scale farming, and are the next generation solution to the control and management of many problems currently faced by cultivators and farmers globally in every field. The ecological impact in reduction of the need to use modern pesticides will improve environmental conditions. Hempyre Genetics has developed these formulations having specific Sesquiterpene percentages with B-Farnesene effective in BlueMagic™. Hempyre Genetics has developed BlueMagic™ as a new product category called Hempicide™. The special method and process applied are referred to as BlueGreenEarthScience™. Slogans for industry category identifier such as PlantsLoveIt™, PestHateIt™, AvoidTheTragic-UseBlueMagic™, Bug Block™, Bug Block Technology™, Eco Friendly Pesticide™ and Ecological Sustainability™ are used in conjunction with the special method and process.
Farnesene is labeled as non-toxic in Ecolabel Lubricant Substance Classification List. Farnesene-derived base oils have undergone extensive toxicity testing for many regulatory registrations (see below attached image), in all tests they were found to be as safe as white oils, which are known to have low toxicity. See, e.g., Table 26.5, reproduced below, from “Synthetics, Mineral Oils, and Bio-Based Lubricants: Chemistry and Technology”, Leslie R. Rudrick, CRC Press, Jan. 29, 2020.

Farnesene, mixture of isomers (https://www.scbt.com/p/farnesene-mixture-of-isomers-502-61-4?lang=en&cur=usd#CertificateAnalysis-collapse) has CAS No. 502-61-4, Molecular weight: 204,35, and Molecular Formula: C15H24. The formulations provided herein are suitable for use in the mitigation and/or prevention of one or more pathogens selected from the group consisting of powdery mildew, leaf aphids, thrips, white flies, russet mites, spider mites, and broad mites.
The formulation is typically provided as a concentrate which is diluted with a suitable diluent, e.g., water, then applied to an infestation or a plant. In one aspect, the concentration comprises an oil as a carrier, along with a surfactant and the sesquiterpene. For example, the concentrate can comprise a mixture of soybean oil 25% by weight, sodium lauryl sulfate 15% by weight, and farnesene 0.02% by weight, with the remainder of the formulation comprising other ingredients 60% by weight (e.g., sodium citrate, citric acid, water, detergent and alcohol) is provided. For regular use or maintenance 1 ounce of the concentrate can be mixed with 1 gallon of water. For treatment of an infestation, 2 ounces of the concentrate can be mixed with 1 gallon of water.
In a typical application, e.g., to a Cannabis sativa or Cannabis indica plant, it is recommended not to apply to plants under a grow light when powered on. Typically, the concentrate is diluted in water, and can be advantageously mixed in a spray bottle by shaking. The plant is sprayed with the diluted concentrate so as to spray the entire plant thoroughly, covering all leaves, stems, and stalk, The plan is allowed to dry before turning grow lights on, as exposure to strong light while wet may cause damage to plants.
The production and use of an agricultural composition for application to plants, such as Cannabis sativa, including a sesquiterpene mixture, namely, a type of farnesene, are provided. Typically, the farnesene formulation is manufactured as a concentrate which is then admixed to provide the agricultural composition. The farnesene formulation may be diluted prior to admixture. Alternatively, the farnesene formulation may be admixed and diluted thereafter. The agricultural composition is typically diluted with water providing a stable spray or tank mix form of diluted agricultural composition prior to use and application onto, or adjacent to, agricultural crops to control pathogen populations and/or control and/or treat disease related to the pathogens, particularly powdery white mildew, e.g., in nursery stock, Cannabis plants, and table and wine grapes. The disclosure extends to application of the agricultural composition to, or adjacent to, soil, buildings, equipment and the like. The agricultural composition according to this disclosure is stable prior to and when in use.
The farnesene is typically provided in admixture with an oil, such as a vegetable oil, e.g., soybean oil. A typical concentrate comprises from 0.005% by weight to 1% by weight of the farnesene, from 10-90% of the oil, with the remainder other ingredients as are typically employed in agricultural compositions. These can include diluents (water, ethanol), buffering agents (sodium citrate and citric acid), and a detergent/surfactant. The farnesene formulation is suitable for dilution in water and is stable as both a concentrate and as a spray or tank mix.
The term “stable” as used herein is a broad term, combined or related with the term “emulsion”, and is to be given its ordinary and customary meaning to a person of ordinary skill in the art (and is not to be limited to a special or customized meaning), and refers without limitation to the emulsion stability, i.e. the ability of an emulsion to resist change in its properties over tune so that the size of the droplets in emulsion does not change significantly with time, more specifically during the time of an application to the targets mixed with water, it is thus to be given its ordinary meaning that is customary to a person skilled in the art. The term “stable” as used herein is a broad term, combined or related with the term “accelerated storage stability”, means that the formulation keep similar performance in terms of physico-chemical properties after samples be stored during 15 days in at least 3 conditions: room temperature (around 20° C.); cold temperature (0° C. or 5° C.); hot temperature (54° C.). Storage stability tests were conducted according Method CIPAC MT 36.
The term “solvents” as used herein is a broad term, and is to be given its ordinary and customary meaning to a person of ordinary skill in the art (and is not to be limited to a special or customized meaning), and refers without limitation to compounds with some characteristics of solvency for other compounds or means, that can be polar or non-polar, linear or branched, cyclic or aliphatic, aromatic, naphthenic and that includes but is no limited to: alcohols, esters, diesters, ketones, acetates, terpenes, sulfoxides, glycols, paraffins, hydrocarbons, anhydrides, heterocyclics, among others.
The term “alcohol” as used herein is a broad term, and is to be given its ordinary and customary meaning to a person of ordinary skill in the art (and is not to be limited to a special or customized meaning), and refers without limitation to any compound as described herein incorporating one or more hydroxy groups, or being substituted by or functionalized to include one or more hydroxy groups.

It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations, ” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not he limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
All numbers expressing quantities of ingredients, reagents, reaction conditions, and so forth used in the specification are to be understood as being modified in all instances by the term ‘about. ’ Accordingly, unless indicated to the contrary, the numerical parameters set forth herein are approximations that may vary depending upon the desired. properties sought to be obtained. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of any claims in any application claiming priority to the present application, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
The agricultural composition according to this disclosure provides for an environmentally friendly, stable, and effective farnesene formulation for pathogen control, e.g., white powdery mildew. The agricultural composition allows easy dosage and easy use. Further, the composition allows for use, alone or in combination with other agricultural treatment protocols in pre-harvest or post-harvest plant crops, seeds, flowers, fruits, vegetables, trees, animals, equipment, cleaning tools, greenhouses, soils, and other spaces on the farm or industrial facilities.
Furthermore, although the foregoing has been described in some detail by way of illustrations and examples for purposes of clarity and understanding, it is apparent to those skilled in the art that certain changes and modifications may be practiced. Therefore, the description and examples should not be construed as limiting the scope of the invention to the specific embodiments and examples described herein, but rather to also cover all modification and alternatives coming with the true scope and spirit of the invention.
