This disclosure features methods for the delivery of combinations (e.g., compositions, e.g., fungicidal compositions) that include a paraffinic oil to one or more plants for, e.g., promoting the health of the one or more plants.
Rusts are plant diseases caused by fungal pathogens of the order Pucciniales. Rusts can affect a variety of plants, including monocotyledons and dicotyledons, as well as various plant organs, including leaves, stems, fruits and seeds. Rust is typically observed as colored powdery pustules composed off tiny spores that form on the lower plant organ surfaces. Common rust-causing fungal species include Gymnosporangium juniperi-virginianae (Cedar-apple rust) which attacks apple and pear and hawthorn; Cronartium ribicola (White pine blister rust); which attacks white pines and currants; Hemileia vastatrix (Coffee rust) which attacks coffee plant; Puccinia graminis (wheat stem rust) which attacks Kentucky bluegrass, barley, and wheat; Puccinia coronata (Crown Rust of Oats and Ryegrass) which attacks oats; Phakopsora meibomiae and P. pachyrhizi (soybean rust) which attacks soybean and various legumes; Uromyces phaseoli (Bean rust) which attacks bean; Puccinia hemerocallidis (Daylily rust) which attacks Daylily; Puccinia persistens subsp. triticina causes (wheat rust in grains, also known as ‘brown or red rust’); P. sriiformis (yellow or stripe rust); Uromyces appendeculatus which attacks bean.
Wheat stem rust is caused by the fungus Puccinia graminis and is a significant disease affecting cereal crops, particularly wheat (Triticum spp.) An epidemic of stem rust on wheat caused by race Ug99 is currently spreading across Africa, the Middle East, and Asia, and threatening large numbers of people who are dependent on wheat for sustenance. The rust fungus attacks the parts of the plant which are above ground. Spores that land on green wheat plants form a pustule that invades the outer layers of the stalk. Where infection has occurred on the stem or leaf, elliptical blisters or pustules called uredia develop. Infected plants produce fewer tillers and set fewer seed.
Soybean rust is a disease that primarily affects soybeans and other legumes. It is caused by two species of fungi, Phakopsora pachyrhizi and Phakopsora meibomiae. Soybean rust has been reported in Asia, Australia, Africa, South America and North America. Soybean rust is spread by wind-borne spores, which are released in cycles of seven days to two weeks. Yield losses can be severe with this disease and losses of 10-80% have been reported.
Multi-pronged approaches are desirable to address the spread of fungal infection. A variety of preventative methods may be employed. For example, rust diseases are correlated to relatively high moisture. Accordingly, avoidance of overhead watering at night, using drip irrigation, reducing crop density, and the use of fans to circulate air flow may serve to lower the relative moisture and decrease the severity of rust infection.
Other strategies may include reducing the area of the plant that the pathogen destroys, or slowing down the spread of the fungus. Fungus-resistant plants may be used to interrupt the disease cycle because many rusts are host-specific. This approach has proven very successful in the past for control of wheat stem rust; however, Ug99 is currently virulent against most wheat varieties. Currently, there are no commercial soybean varieties with resistance to soybean rust. Accordingly, soybean rust is managed with fungicides.
In large agricultural operations, conventional synthetic fungicides can be used to control fungal pathogens. De-methylation inhibitors (DMI) such tebuconazole (Folicur™, Bayer) and propioconazole (Tilt™) may be effective for the control of wheat stem rust, while tetraconazole (Domark™, Valent) be effective for the control of soybean rust. Quinone Outside Inhibitors (QoI), such as pyraclostrobin (Headline™, BASF), may be effective for the control of soybean rust, while azoxystrobin (Quadris™) may be effective for the control of wheat stem rust.
Conventional fungicides are generally applied by air to the foliage as contact between the pathogen with the fungicide is required for efficacy. This process can expensive and fungicide application is often reserved for seasons when foliar diseases are severe. Second, conventional fungicides typically target specific sites of important pathogen proteins. Accordingly, strains may develop resistance to the fungicide after repeat applications. Third, the efficacy of conventional chemical fungicides is not always satisfactory for some of the diseases, such as Fusarium Head Blight (Scab). Finally, conventional fungicides are generally not acceptable for use in organic farming.
As an alternative approach to conventional chemical fungicides, oil-in-water emulsions comprising paraffinic oils (paraffinic oil-in-water emulsions) and paraffinic spray oils have been used in turfgrass management practices for controlling turfgrass pests (see, for example, Canadian Patent Application 2,472,806 and Canadian Patent Application 2,507,482). In addition, oil-in-water formulations comprising paraffinic oils and a pigment for controlling turfgrass pests have been reported (see, for example, WO 2009/155693). For example, Petro-Canada produces CIVITAS™, is a paraffinic oil-in-water emulsion that functions as a broad spectrum fungicide and insecticide for use on golf course turf and landscape ornamentals, used for example to control powdery mildew, adelgids and webworms on landscape ornamentals (US EPA REG. NO. 69526-13). Product labeling indicates that CIVITAS™ may be applied as part of an alternating spray program or in tank mixes with other turf and ornamental protection products; and that CIVITAS™ may be used as a preventative treatment with curative properties for the control of many important diseases on turf, including fairways and roughs.
This disclosure features methods for the delivery of combinations (e.g., compositions, e.g., fungicidal compositions) that include a paraffinic oil to one or more plants. The methods include applying the combinations (e.g., compositions, e.g., fungicidal compositions) to one or more plants in a manner that facilitates plant uptake of the paraffinic oil primarily by absorption through the root system of the one or more plants. It has been surprisingly found that that combinations (e.g., compositions, e.g., fungicidal compositions) applied in this manner are effective for promoting the health of the one or more plants (e.g., at least as effective as a foliar application of the combinations (e.g., compositions, e.g., fungicidal compositions).
Advantageously, the methods described herein can provide ease of use to the end-user. For example, the methods described herein can facilitate the treatment of particularly large and/or tall plants (e.g., trees) since the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied at ground level, e.g., at the base of the large and/or tall plants (e.g., trees), for example during regular watering. As another example, the methods described herein can make use of existing irrigation infra-structure, thereby obviating the need for the additional acquisition of spraying equipment to apply the combinations (e.g., compositions, e.g., fungicidal compositions). As a further example, the methods described herein provide an alternative to aerial application of pesticide (e.g., crop dusting) which can be associated with environmental concerns, including spray drift and occupational health. In some cases, In still yet another example, the methods described herein can also avoid the potential injury (e.g phytotoxicity) on the foliage that can sometimes be associated with foliar application of a fungicide.
While not wishing to be bound by theory, it is believed that applying the combinations (e.g., compositions, e.g., fungicidal compositions) described herein to the root tissue in a plant increases the amount of endophytiic bacteria living inside the roots of the plant. It is believed that Root endophtyes invade openings in the roots from the soil, and live inside plants without causing disease. Endophytes may activate ISR in the plant and result in the activation of faster and stronger resistance to later attack by pathogens. In some instances, many of these endophytes, along with bacteria associated with the root surface, not only result in ISR, but also enhance plant growth. It is thought that plants can detect various compounds produced by these bacteria and then respond to them.
The combinations (e.g., compositions, e.g., fungicidal compositions) can further include (but are not limited to) one or more of the following: one or more emulsifiers, one or more pigments, one or more silicone surfactants, one or more anti-settling agents, one or more other active agents (e.g., conventional chemical fungicides (e.g., a DMI or a QoI); or one or more plant growth regulators), and water. In some implementations, the combinations can be in the form of a single composition (e.g., which is contained within a storage pack). Typically, the composition is applied after dilution with water (e.g., by soil drench). In other implementations, the combinations can include two or more separately contained (e.g., packaged) compositions, each containing one or more of the above-mentioned components. Said compositions can be combined and applied after dilution with water; or each composition can be applied separately either simultaneously or sequentially, and after dilution with water (e.g., by soil drench).

In one aspect, methods for promoting the health of a tree are featured, which include applying a composition that includes a paraffinic oil to trunk of the tree.
The methods described herein are useful for promoting the health of a plant (e.g., controlling a disease, condition, or injury caused by a pest of a plant; e.g., controlling a disease caused by fungal pathogen; e.g., controlling infection of a plant by a fungal pathogen; e.g., controlling infection of a plant by a biotic agent). Such methods are featured in this disclosure along with uses of the combinations (e.g., compositions, e.g., fungicidal compositions) for any one or more of the above-described utilities.

The composition can be applied to a growing medium that is in proximity to a base and root system of the plant, wherein the amount of the composition that is applied to the growing medium is sufficient to penetrate the growing medium and contact the root tissue for uptake by the plant.
In general, the combinations (e.g., compositions, e.g., fungicidal compositions) are applied in an amount that is greater than the amount, which would contact the growing medium by run-off after spraying the ariel portions of the plant with the same amount of the combinations (e.g., compositions, e.g., fungicidal compositions). Examples of such amounts are provided throughout this disclosure.

In some implementations, an oil-in-water emulsion is prepared by a process that includes combining the paraffinic oil, water, and any other components and the paraffinic oil and applying shear until the emulsion is obtained. Typically a white milky color is indicative of the formation of an emulsion in the absence of any pigment; and a green color is observed in the presence of a pigment.
The oil-in-water emulsion can be used in a range from 200 to 400 gallons per acre for soil drench application or water-in application (including irrigation water).

In some implementations, applying is carried out by soil drenching. In some implementations, applying is carried out by drip irrigation.
As used herein, the term “crop plant” refers to a non-woody plant, which is grown, tended to, and harvested in a cycle of one year or less as source of foodstuffs and/or energy. Examples of crop plants include, without limitation, sugar cane, wheat, rice, corn (maize), potatoes, sugar beets, barley, sweet potatoes, cassava, soybeans, tomatoes, legumes (beans and peas).
As used herein, the term “tree” refers to a woody perennial plant having a single stem or trunk and bearing lateral branches at some distance from the ground. In certain implementations, the tree is deciduous. In other implementations, the tree is evergreen (e.g., coniferous). In still other implementations, the tree is deciduous or evergreen and is grown, tended to, and harvested in a cycle of one year or less as source of foodstuffs. In a further implementation, the plant is a shrub. Examples of trees include, without limitation, maple trees, citrus trees, apple trees, pear trees, an oak tree, an ash tree, a pine tree, and a spruce tree.
In some implementations, the plant is a turf grass. As used herein, the term “turf grass” refers to a cultivated grass that provides groundcover, for example a turf or lawn that is periodically cut or mowed to maintain a consistent height. Grasses belong to the Poaceae family, which is subdivided into six subfamilies, three of which include common turf grasses: the Festucoideae subfamily of cool-season turf grasses; and the Panicoideae and Eragrostoideae subfamiles of warm-season turf grasses. A limited number of species are in widespread use as turf grasses, generally meeting the criteria of forming uniform soil coverage and tolerating mowing and traffic. In general, turf grasses have a compressed crown that facilitates mowing without cutting off the growing point. In the present context, the term “turf grass” includes areas in which one or more grass species are cultivated to form relatively uniform soil coverage, including blends that are a combination of differing cultivars of the same species, or mixtures that are a combination of differing species and/or cultivars.
Examples of turf grasses include, without limitation:
As used herein, the term “controlling infection of a plant by a biotic agent” (and the like) means to diminish, ameliorate, or stabilize the infection and/or any other existing unwanted condition or side effect that is caused by the association of a pest organism with the plant include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes, parasitic plants and insects.
As used herein, the term “control a fungal pathogen of a plant” or “control a disease caused by a fungal pathogen” (and the like) means to diminish, ameliorate, or stabilize the disaease and/or any other existing unwanted condition or side effect that is caused by the association of a fungal pathogen with the plant.
As used herein, the term “controlling infection of a plant by a fungal pathogen” (and the like) means to diminish, ameliorate, or stabilize the infection and/or any other existing unwanted condition or side effect that is caused by the association of a fungal pathogen with the plant.
As used herein, the term “controlling a disease, condition, or injury caused by a pest of a plant” (and the like) means to diminish, ameliorate, or stabilize the disease, condition, or injury and/or any other existing, unwanted condition(s) or side effect(s) that caused by the association of a pest of a plant with the plant.
As used herein, the term “pest of a plant” (and the like) is used to refer to living organisms occurring on plants that are not desired to occur on plants or that cause injury or disease to plants. Examples include fungi, bacteria, viruses, spiders, ticks, mites, nematodes, gastropods and insects.
In certain implementations, the combinations, e.g., fungicidal compositions, exhibit a synergistic response, for example in controlling a fungal pathogen in a crop plant. In certain implementations, the combinations, e.g., fungicidal compositions may be synergistic fungicidal compositions for treating a fungal pathogen in crop plants. In selected implementations, the fungicidal compositions may exhibit a synergistic response, for example in controlling stem rusts in crop plants. As for example is suggested by Burpee and Latin (Plant Disease Vol. 92 No. 4, April 2008, 601-606), the term “synergy”, “synergistic”, or the like, may refer to the interaction of two or more agents so that their combined effect is greater than the sum of their individual effects, this may include, in the context of the invention, the action of two or more fungicidal agents in which the total response of a fungus to the fungicidal agent combination is greater than the sum of the individual components. Applying the approach to identifying synergy a set out in S. R. Colby, “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, 20-22 (1967), expected efficacy, E, may be expressed as: E=X+Y(100−X)/100, where X is the efficacy, expressed in % of the untreated control, of a first composition, and Y is the efficacy, expressed in % of the untreated control, of the second composition.
The details of one or more implementations of the combinations and methods described herein are set forth in the accompanying description below. Other features and advantages of the combinations and methods described herein will be apparent from the description and drawings, and from the claims.
This disclosure features methods for the delivery of combinations (e.g., compositions, e.g., fungicidal compositions) that include a paraffinic oil to one or more plants. The methods include applying the combinations (e.g., compositions, e.g., fungicidal compositions) to one or more plants in a manner that facilitates plant uptake of the paraffinic oil primarily by absorption through root system of the one or more plants. It has been surprisingly found that that the combinations (e.g., compositions, e.g., fungicidal compositions) applied in this manner are effective for promoting the health of the one or more plants (e.g., at least as effective as a foliar application of the combinations (e.g., compositions, e.g., fungicidal compositions).

[B] Paraffinic Oil
The paraffinic oil confers properties (e.g., fungicidal properties) that are useful for promoting the health of a plant (e.g., crop plant). While not wishing to be bound by theory, it is believed that the paraffinic oil is able to provoke an induced systemic resistance (ISR) response, a systemic acquired resistance (SAR), or other defense response in a plant.
[1]
In some implementations, the paraffinic oil includes an oil enriched in paraffin.
In certain implementations, the paraffinic oil includes a paraffin having from 12 carbon atoms to 50 carbon atoms (e.g., 12 carbon atoms to 40 carbon atoms, 16 carbon atoms to 35 carbon atoms, 12 carbon atoms to 21 carbon atoms; e.g., 16 carbon atoms to 35 carbon atoms).
In certain implementations, the paraffinic oil includes a paraffin having an average number of carbon atoms that is less than or equal to about 20 (e.g., 16).
In certain implementations, the paraffinic oil includes a paraffin having an average number of carbon atoms of from 16 to 30 e.g., 23 or 27).
In certain implementations, the paraffinic oil includes a paraffin having from 16 carbon atoms to 35 carbon atoms and an average number of carbon atoms of 23.
In certain implementations, the paraffin is an isoparaffin (e.g., a synthetic isoparaffin manufactured from two-stage Severe Hydrocracking/Hydroisomerization process).
In some implementations, a paraffin is present in the paraffinic oil in an amount, that is at least 80% (e.g., at least 90%, at least 99%).
[2]
In some implementations, the paraffinic oil has been refined to remove compounds that are associated with plant injury, for example, aromatic compounds or compounds containing sulfur, nitrogen, or oxygen. In certain implementations, the paraffinic oil includes relatively low levels of aromatic compounds and/or compounds containing sulfur, nitrogen, or oxygen, e.g., less than 10 weight percent (less than 5 weight percent, less than 2 weight percent, less than 0.5 weight percent) of aromatic compounds and/or compounds containing sulfur, nitrogen, or oxygen.
[3]
Non-limiting examples of suitable paraffinic oils include, HT60, HT100, High Flash Jet, LSRD, and N65DW (available from Petro-Canada, Calgary, AB, Canada).
[C] Emulsifier
In some implementations, the combinations include both paraffinic oil, emulsifier, and water. It can be advantageous to store and/or apply such combinations as oil-in-water (O/W) emulsions.
Emulsions tend to be thermodynamically unstable due to excess free energy associated with the surface of the dispersed droplets such that the particles tend to flocculate (clumping together of dispersed droplets or particles) and subsequently coalesce (fusing together of agglomerates into a larger drop or droplets) to decrease the surface energy. If these droplets fuse, the emulsion will “break” (i.e., the phases will separate) destroying the emulsion, which in some cases can be detrimental to the storage shelf-life of the combinations. While not wishing to be bound by theory, it is believed that the addition of one (or more) emulsifying agents or emulsifiers can prevent or slow the “breaking” of an emulsion. As the skilled artisan will appreciate, the type and concentration of a particular emulsifying agent will depend, inter alia, on the emulsion phase components and the desired result.
[1]
In some implementations, the emulsifier is a “fast break” or “quick break” emulsifier. While not wishing to be bound by theory, it is believed that a “fast break” or “quick break” emulsifier allows the paraffinic oil to be quickly released from the O/W emulsion upon application to the turfgrass for contact, e.g., with a fungal pathogen. When a “fast break” or “quick break” emulsifier is present in a suitable amount (for example a selected proportion or ratio with respect to the paraffinic oil), the resulting “fast break” or “quick break” O/W emulsion quickly releases the oil phase upon application to the turfgrass. As such, there is less runoff of the O/W emulsion from the grass blades (as compared to more stable O/W emulsions) resulting in more oil adhering to the turfgrass for a longer period of time to more effectively contact and control, e.g., associated fungal pathogen. In certain implementations, the oil phase resides on the turfgrass for a period of not less than one hour. In certain implementations, the oil phase resides on the turfgrass for a period of from not less than 1 hour but not more than 30 days. In certain implementations, the “fast break” or “quick break” emulsion may be, for example, an emulsion having an oil phase that, after mixing with water, is reconstituted in 0.5 to 15 minutes according to the following test:
In some implementations, the oil phase is reconstituted in from 2 minutes to 5 minutes according to the test described above. In some instances, the “fast break” or “quick break” property of the O/W emulsion is balanced with the need to provide an O/W emulsion with a suitable shelf life under suitable storing conditions, and for a suitable timeframe.

In certain implementations, (2-a) applies; or (2-a), (2-b) and (2-c) apply; or (2-b), and (2-c) apply. In certain implementations, (2-d) further applies to any one of the above-listed combinations of (2-a), (2-b) and (2-c).
In some of the implementations described in section [II][A][1], one or more of the following applies:
(2-aa) the concentrate includes from 50 to 300 parts per weight (e.g., 200-300, e.g., 260; e.g., 50-150, e.g., 100) parts per weight of the paraffinic oil;
(2-bb) the concentrate includes from 1 to 10 parts per weight (e.g., 3-7, e.g., 5; e.g., 1-5, e.g., 1.9, e.g., 2) parts per weight of the emulsifier;
(2-cc) the concentrate includes from 1 to 15 parts per weight (e.g., 7-11, e.g., 9; e.g., 2-5, e.g., 3.5) parts per weight of the pigment;
(2-dd) the concentrate includes from 0.1 to 10 parts per weight (e.g., 0.5-1, e.g., 0.8, e.g., e.g., 2-5, e.g., 3.1) parts per weight of the silicone surfactant;
(2-ee) the concentrate includes from 0.5 to 20 parts per weight (e.g., 6-10, e.g., 8; e.g., 2-5, e.g., 3.1) parts per weight of the anti-settling agent; or
(2-ff) the concentrate includes from 0.01 to 10 parts per weight (e.g., 0.5-1, e.g., 0.8, e.g., e.g., 1-3, e.g., 2) parts per weight of the conventional chemical fungicide.
In certain implementations, (2-aa) and (2-bb) apply; or (2-cc) and (2-dd) apply; or (2-aa), (2-bb), and (2-ff) apply; or (2-cc), (2-dd), and (2-ff) apply; or (2-aa), (2-bb), (2-cc), and (2-dd) apply, or (2-aa), (2-bb), (2-cc), (2-dd), and (2-ff) apply. In certain implementations, (2-ee) further applies to each of the above-listed implementations.
In some implementations, any one or more of the features described in one or more of (2-a) and (2-d) can be combined with any one or more of the features described in one or more of (2-aa) and (2-ff).
In some implementations, the pigment is dispersed in compatible oil, e.g., a paraffinic oil, e.g., the same paraffinic oil as is used to provide the fungicidal properties as described herein, for addition to the other components of the combinations described herein. In certain implementations, a silicone surfactant and/or emulsifier and/or anti-settling agent can be included, e.g., to stabilize the pigment in the oil-based combination.
For example, polychlorinated Cu (II) phthalocyanine can be dispersed in a paraffinic oil, such as N65DW (available from Petro-Canada) to provide about 18% polychlorinated CU (II) phthalocyanine (SUNSPERSE® EXP 006-102, available from Sun Chemical Corp. Performance Pigments, Cincinnati, Ohio USA) prior to mixing with the remaining components. In certain implementations, a silicone surfactant and/or emulsifier and/or anti-settling agent can be included. While not wishing to be bound by theory, it is believed that the addition of these components can provide an intermolecular hydrophilic and lipophilic balance within the fungicidal formulation so as to substantially prevent the polychlorinated Cu (II) phthalocyanine from separating out of suspension during application, e.g., to a turf grass.
In some of the implementations described in section [II][A][1], the composition includes the components present in Civitas™ 1-pack and those present in commercially available conventional chemical fungicides described anywhere herein.
[3]
In some of the implementations described in sections [II][A][1] and [II][A][2], the composition further includes water. In certain implementations, weight percent ratio of the undiluted composition to water is from 1:1 to 1:100 (e.g., from 1-50, 1-30, 1-20, 1-15). In certain implementations, the weight percent of the paraffinic oil in the diluted compositions is from 2 to 50 weight percent (e.g., 15%). In certain implementations, the composition is in the form of an oil in water emulsion as described anywhere herein.
In some implementations, the pigment is dispersed in water for addition to the other components of the combinations described herein. In certain implementations, a silicone surfactant and/or emulsifier and/or anti-settling agent can be included, e.g., to stabilize the pigment in the oil/water-based combination.
For example, polychlorinated Cu (II) phthalocyanine can be dispersed in a water to provide about 40% polychlorinated CU (II) phthalocyanine (SUNSPERSE® GREEN 7, available from Sun Chemical Corp. Performance Pigments, Cincinnati, Ohio USA) prior to mixing with the remaining components. In certain implementations, a silicone surfactant and/or emulsifier and/or anti-settling agent can be included. While not wishing to be bound by theory, it is believed that the addition of these components can provide an intermolecular network so as to substantially prevent the polychlorinated Cu (II) phthalocyanine from separating out of suspension during application, e.g., to a turf grass.

In certain implementations, (2-aaa) applies; or (2-aaa), (2-bbb) and (2-ccc) apply; or (2-bbb), and (2-ccc) apply. In certain implementations, (2-ddd) further applies to any one of the above-listed combinations of (2-aaa), (2-bbb) and (2-ccc).
In some of the implementations described in section [II][B][1], one or more of the following applies:
(2-aaaa) the composition (concentrate) includes from 50 to 300 parts per weight (e.g., 100) parts per weight of the paraffinic oil;
(2-bbbb) the composition (concentrate) includes from 1 to 10 parts per weight (e.g., 1.9, e.g., 2) parts per weight of the emulsifier;
(2-cccc) the composition (concentrate) includes from 1 to 10 parts per weight (e.g., 3.5) parts per weight of the pigment;

[3]
In some of the implementations described in sections [II][B][1] and [II][B][2], each of the compositions, independently, further includes water. In certain implementations, the combination of compositions (concentrates) described above are combined and diluted with water ((e.g., volume of the diluted end product is 100 to 800 gal/acre, e.g., 200 to 400 gal/acre). In certain implementations, oil in the end product is from 80 to 640 oz/acre (other components can be calculated based on ratio with oil).
[C] As the skilled artisan will appreciate, the weight percent of a given component(s) can vary, e.g., due to dilution with water or whether the combination is in the form of a single composition or two or more separately contained compositions. In some implementations, the weight ratio of any two or more components is essentially the same regardless of whether the combination is in the form of a single composition (diluted with water or undiluted) or in the form two or more separately contained compositions (diluted with water or undiluted). In the latter case, this can be achieved by adjusting the component amounts in each of the separately contained compositions to match, for example, a weight percent ratio employed in single composition combination.
III. Application of Combinations
[A]
In some implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) described herein can be applied by contacting the surface of the growing medium with a combination as described anywhere herein (e.g., by pouring), contacting an area that is beneath the surface of the growing medium with a combination as described anywhere herein, or any combination thereof.
In some implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied to a growing medium that is in proximity to a base and root system of the plant, wherein the amount of the composition that is applied to the growing medium is sufficient to penetrate the growing medium and contact the root tissue for uptake by the plant.
In certain implementations, the growing medium (e.g., soil) can include any surface of the growing medium that is from 0 inches to six feet (e.g., 0 inches to five feet, 0 inches to four feet, 0 inches to three feet, 0 inches to two feet, 0 inches to 12 inches, 0 inches to six inches, 0 inches to one inch, 0 inches to 0.5 inch) from the base of the plant and any growing medium that is from 0 inches to 24 inches beneath said surface of the growing medium. In other implementations, the length of the surface of the growing medium can be determined on the basis of the height of the plant, e.g., can correspond to the shade radius of the plant (i.e., the distance around the plant that is shaded during daylight hours due to the height of the plant).
In certain implementations, when the plant is a tree, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied to the trunk of the tree.
In general, the combinations (e.g., compositions, e.g., fungicidal compositions) are applied in an amount that is greater than the amount, which would contact the growing medium by run-off after spraying the ariel portions of the plant with the same amount of the combinations (e.g., compositions, e.g., fungicidal compositions).
For example, the plant can be a crop plant (e.g., wheat, barley, soybean, tomatoes, potatoes, or corn, or any combination thereof; e.g., wheat or tomatoes). In certain implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) further includes from 50 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion). In certain implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied at a rate of from 100 gal/acre to 800 gal/acre (e.g., 200 gal/acre to 400 gal/acre). In certain implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) further includes from 50 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion), and the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied at a rate of from 100 gal/acre to 800 gal/acre (e.g., 200 gal/acre to 400 gal/acre). In certain implementations, the oil can be applied at a rate of from 1 gal/acre to 20 gal/acre.
As another example, the plant can be a tree (e.g., a maple tree, a citrus tree, an apple tree, a pear tree, an oak tree, an ash tree, a pine tree, or a spruce tree, or any combination thereof; e.g., a maple tree). In certain implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) further includes from 5 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion). In certain implementations, the oil can be added at a rate of from 1 oz to 2 gallons of the combinations (e.g., compositions, e.g., fungicidal compositions) per inch of tree diameter. In certain implementations, the composition further includes from 5 to 99 parts per weight of water (e.g., the composition can be an oil-in-water emulsion), and the oil can be added at a rate of from 1 oz to 2 gallons of the combinations (e.g., compositions, e.g., fungicidal compositions) per inch of tree diameter.
In some implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied over a time period of at least ten seconds (e.g., at least five seconds, at least two seconds).
In some implementations, the aerial exterior portion of the plant is free (e.g., contains less than 5%, or 4%, or 3%, or 2%, or 1%, or 0%) of the combinations (e.g., compositions, e.g., fungicidal compositions) during application of the composition to the root tissue. In certain implementations, the composition is not applied to any aerial portion of the plant during application of the combinations (e.g., compositions, e.g., fungicidal compositions) to the root tissue.
In some implementations, the aerial exterior portion of the plant is free (e.g., contains less than 5%, or 4%, or 3%, or 2%, or 1%, or 0%) of the combinations (e.g., compositions, e.g., fungicidal compositions). In certain implementations, the composition is not applied to any aerial portion of the plant.
In some implementations, the method can further include applying one or more conventional chemical fungicides to the plant (e.g., the one or more conventional chemical fungicides can be applied to an aerial portion of the plant).
In some implementations, applying is carried out by soil drenching (e.g., by pouring the combinations described herein as a bolus on the surface of the growing medium or soaking a plant tray in the combinations described herein, e.g., root bathing).
In some implementations, applying is carried out by drip irrigation.
In some implementations, applying is carried out by soil injection.
In some implementations, the combinations (e.g., compositions, e.g., fungicidal compositions) may be reapplied as required.
In some implementations, the method can further include adding water (e.g., to the growing medium) after the composition has been applied. In certain implementations, the methods can further include “watering in” the combinations (e.g., compositions, e.g., fungicidal compositions). For example, the combinations (e.g., compositions, e.g., fungicidal compositions) can be applied first to a growing medium (e.g., soil) and then watered in with, e.g., 0.5 to 2 inches of water.
In some implementations, the combinations include both paraffinic oil and water. It is advantageous to apply such combinations as oil-in-water (O/W) emulsions. In some implementations, an oil-in-water emulsion is prepared by a process that includes combining the paraffinic oil, water, and any other components and the paraffinic oil and applying shear until the emulsion is obtained.
In other implementations, the combinations can include two or more separately contained (e.g., packaged) compositions, each containing one or more of the above-mentioned components. Said compositions can be combined and applied to an area of the growing medium with or without prior dilution with water; or each composition can be applied separately to the same to an area of the growing medium either simultaneously or sequentially, and each independently applied with or without prior dilution with water.
In the above-described implementations, application of any one (or more) compositions can be repeated one or more times.

Civitas™ Harmonizer™, and combinations thereof were applied to test plants, by foliar application, on March 10th, seven days before inoculation (DBI) on March 17th as indicated in Table
The efficacy of Civitas™ alone or in combination with Harmonizer™, Folicur™ or Quilt™ in controlling infection of wheat (Triticum aestivum ‘Norin43’) by Pgt was tested between May and July. A field was treated with Roundup™ on May 9th and cultivated twice before planting. Plots were planted on May 28 using a seeding rate of 1.25 bu/A, and were 15 ft long by 5 ft wide with 7 rows. Due to flooding in the field shortly after planting, plots lengths were reduced to 7 ft long prior to cutting of the alleys. Plots consisting of a highly susceptible rust spreader mixture were alternated with the experimental units.
The experimental design was a randomized complete block with five replicates. Puma™ (0.4 pt/A) and Bronate Advanced™ (0.8 pt/A) were applied on June 10th to control weeds. On July 14th, urediniospores of Pgt were collected from nearby trap plots and applied to the spreader rows in a 0.1% water agar suspension using a hand-powered backpack sprayer. On July 20th, fungicide treatments were applied with a CO2-powered backpack sprayer in a carrier volume of 20 gal/A using XR8002 flat fan nozzles and an application pressure of 40 PSI. The plants in each plot were at Feekes 10.51 (early anthesis). At 48 hr after fungicide application, the experimental plots were inoculated as previously described with Pgt and misted at night for 7 days (3 min on per each 30 min) to facilitate infection and disease development. One treatment received a second application 7 days later (Treatment 5, see Table 8 below). Plots were rated for stem rust severity at 14 d after inoculation by visually estimating the percentage of stem area covered with pustules for 50 plants per plot (5 randomly chosen locations of 10 plants each). Plots were harvested with a small plot combine and yield was determined. Data were analyzed using an ANOVA and pair-wise comparisons were performed using Tukey's HSD (P=0.05).
The efficacy of Civitas™/Harmonizer™, alone or in combination with Folicur™ in controlling infection of wheat (Triticum aestivum ‘Baart’) by Bipolaris sorokiniana was tested under greenhouse conditions. Briefly, each treatment consisted of three pots (4″ by 4″) containing three plants each. Plants were planted on March 1st. Civitas™/Harmonizer™, Folicur™, and combinations thereof were applied to test plants, by foliar application on March 8 (seven DBI), by soil drench on March 8th (7 DBI), or by foliar application on March 14th (1 DBI), as indicated in Table 9 (rates of Civitas, Harmonizer, and Folicur are expressed in oz/acre). For foliar application, the treatments were applied in 0.2 mL per pot, which is the equivalent of 20 gal/A. For soil drench, treatments were applied in 3.8 mL, which is the equivalent of 400 gal/A. Plants were innoculated on March 15th. The average severity of infection, in terms of % leaf area infected, was evaluated 14 days after inoculation on March 29th.

The efficacy of Civitas™, Harmonizer™, and Folicur™ alone or in combination, in controlling infection of wheat (Triticum aestivum ‘Sonalika’) by Fusarium graminearum was tested under greenhouse conditions. Briefly, each treatment consisted of four pots (4″ by 4″) containing nine plants each. Plants were planted on March 2nd. Civitas™ Harmonizer™, Folicur™, and combinations thereof were applied to test plants, by foliar application or by soil drench on March 10 (39 DBI), or 35 DBI by foliar application on March 16th, as indicated in Table 11 (rates of Civitas, Harmonizer, and Folicur are expressed in oz/acre). For foliar application, the treatments were applied in 0.2 mL per pot, which is the equivalent of 20 gal/A. For soil drench, treatments were applied in 3.8 mL, which is the equivalent of 400 gal/A. Plants were innoculated on April 18th. The average severity of infection was evaluated 14 days after inoculation on May 2nd.
The efficacy of Civitas™, Harmonizer™, and Headline™ (Pyraclostrobin, BASF), and Domark®230 ME (Tetraconazole, Valent), alone or in combination, in controlling infection of soybean (Glycine max) by Phakospora pachyrhizi was tested in the field in Georgia. Civitas was tested at 640 oz/a (5 gal/a) and 320 oz/a (2.5 gal/a), with and without Harmonizer. Two conventional chemical fungicides that are labelled for soybean rust, Headline® and Domark®230 ME were used alone, as well as tank mix partners with Civitas. The total spray volume is 15 gal/a, significantly lower than the spray volume for turf applications (50-100 gal/a). Accordingly, the concentrations of the Civitas solution were much higher than in turf application (16% to 33% in this study). The treatments are listed in Table 12. The results of this study are provided in Table 13. Civitas showed significant control of Phakospora pachyrhizi on soybean. The incidence and severity were equal to or exceeded control by the conventional fungicides. The combination of the conventional fungicides with Civitas alone or Civitas/Harmonzier provided better efficacy than the conventional fungicides used alone.

Leaf rust field trial was carried out on spring wheat cultivars. Spores from the spreader plots were served as innoculum source for the natural infection of experimental plots. Treatments were applied at heading (Feekes 10.1/10.2) using a CO2-powered backpack sprayer operating at the pressure of ca. 276 kPa, fitted with flat-fan spray tip (TeeJet SS8003; Spraying Systems Co., Wheaton, Ill.), at the rate of 20 gal per acre. Prosaro (Bayer Crop Science) was used as the standard chemical control.
Disease rating was done 19 days after chemical spray. Leaf rust severity was rated as percent leaf area infected on 12 randomly selected flag leaves per plot. Data were analyzed using ‘R’ statistical package. Data on leaf rust severity was transformed using square root and arcsin function for analysis of variance. Means presented for rust severity in the graph and tables are back transformed mean value.
The treatments of Civitas/Harmonizer (160:10 oz/acre) and Civitas/Harmonizer (320:20 oz/acre) resulted in significantly low rust infection compared to control plots. The efficacy of Civitas treatments are at par with the chemical standard Prosaro (6.5 oz/acre).
Gray Leaf Spot (Cercospora zeae-maydis) field trial was conducted on hybrid corns (NK 67 3000GT) with natural infection. Civitas treatments were applied at R1 and R3 growth stage with the spray rate of 20 gal per acre. Headline (BASF) and Stratego (Bayer Crop Science) were applied at R1 as the standard chemical control.
Disease rating was done about 16 days and 40 days after R1 application. Gray leaf spot severity was rated as percent leaf area infected in the plots.
All of the chemical treatments resulted in lower disease severity than control plots.
Although various embodiments of the invention are disclosed herein, many adaptations and modifications may be made within the scope of the invention in accordance with the common general knowledge of those skilled in this art. Such modifications include the substitution of known equivalents for any aspect of the invention in order to achieve the same result in substantially the same way.
Maple saplings (˜50 cm tall) were transplanted into pots containing 50% compost and 50% sand topdressing mix in May.
A randomized complete block design (RCBD) with seven treatments (Table 16) and four replicate trees per treatment was set up. Each tree was sprayed twice with the same treatment (28 May and 16 June). Treatments were mixed by volume with deionized water.
For foliar treatments, up to 30 ml were applied by spraying both foliar surfaces (adaxial and abaxial) of all leaves on a tree until run-off while attempting to minimize dripping onto the soil. For soil treatments, 5.5 ml was applied to each pot, and 1.7 L of water was added, which was sufficient to drench the treatment into the soil without water leaching out at the bottom of the pot. Observations of the number of spots per plant were made in August. The data were subjected to Analysis of Variance, and means separated by the test of Least Significant Difference at p=0.05.
Civitas and Civitas+Harmonizer were applied either sprayed directly on the leaves or applied directly to the soil. The results demonstrate that Civitas or Civitas+harmonizer when applied to the soil was statistically just as effective as when applied foliarly. For soil applications, Civitas+harmonizer were more effective than Civitas alone.
Materials & Methods
Tomato variety ‘TSH4’ was seeded into Fafard germination mix on January 4. Each replicate consisted of a 25 cell square cut from a 200-cell size transplant tray, for a total of 25 transplants per replicate or one plant per cell. Seeds were covered with a medium grind vermiculite, placed in a seed germination room for three days, and then moved to greenhouse. Replicates were arranged in a randomized complete block design with four replications per treatment. Plants were fertilized with 200 ppm of 20-20-20 (NPK) at 14, 20, 26, 30, 36, and 44 DAS.
The standard Kocide 2000 (copper hydroxide, 53.8%) treatment was applied 21, 25, 30, 38, and 45 days after seeding (DAS). The treatments were applied using a hand-held mist sprayer using an application rate of 1000 L of water Ha-1. Civitas and Harmonizer were applied 21 DAS. Soil injection treatments were applied by filling a syringe with 0.6 mL of solution, wiping the outside of the barrel with a cotton ball, and applying the solution to the growing media in each cell. Tray soak treatments were applied by soaking trays in the treatment solution until the trays were fully saturated.
Inoculum was prepared in tryptic soy broth, and diluted to a concentration 106 CFU mL-1 in sterile distilled water with 0.025% v/v Sylgard 309. After inoculation, the trial was enclosed in a plastic tent structure in order to maintain leaf wetness and relative humidity. Few symptoms were apparent 6 days after the first inoculation, so the trial was inoculated for a second time 31 DAS using a slurry tomato leaves infected with Pst (01T23B). Tomato leaves (28 g) were collected and blended with 200 mL of distilled water for 30 seconds. The mixture was filtered through 3 layers of cheese cloth, Sylgard 309 was added (0.025% v/v) was added, and the mixture was applied to the tomato plants using a handheld mist sprayer until run-off.
The number of lesions on all true leaves in each replicate was counted one each assessment date. Phytotoxicity symptoms were observed 19 days after the Civitas and Harmonizer treatments were applied in the injection application treatments. At the end of the study period, foliar weight was measured by removing plant from nine cells in the centre of each replicate, placing the plant material in paper envelopes in a drying oven (70° C.), and recording the dry weight. Samples to measure foliar dry weight were taken 49 DAS.
Statistical analysis was conducted using ARM 7 (Gylling Data Management, Brookings, S. Dak.). Data were tested for normality using Bartlett's homogeneity of variance test. Data which were not normal (P≤0.05) were transformed. Analysis of variance was conducted and means comparisons were performed when P≤0.05, with Duncan's new multiple range test.

Results
The quality and yield of processing tomato can be greatly impacted by a number of diseases. For example, bacterial speck (Pseudomonas syringae pv. tomato) and bacterial spot, (primarily Xanthomonas vesicatoria Group B and X. gardneri Group D) have reduced yields in Ontario by up to 60% (Cupples et al. 2006, LeBoeuf et al. 2005). There are few effective management tools for these diseases other than sanitation and numerous applications of copper during transplant and field production.
One application of Civitas 5% v/v+Harmonizer 5% v/v, applied by soil injection or soaking transplant trays in the product solution, was as effective as five application of the standard bacteriacide Kocide 2000
PEST(S): Bacterial spot (Xanthomonas gardneri syn. Xanthomonas campestris pv. vesicatoria Group D); bacterial speck (Pseudomonas syringae pv. tomato).
MATERIALS: Kocide 2000 (copper hydroxide 53.8%), Civitas and Civitas Harmonizer.
METHODS: Tomato transplants (cv. H9909) were transplanted into twin-rows on June 6 using a mechanical transplanter at a rate of 3 plants per metre. Each set of twin-rows were spaced 1.5 m apart. Each treatment plot was 7 m long and consisted of one twin-row. The trial was setup as a randomized complete block design, with 4 replications per treatment.
Foliar treatments were applied using a 1.5 m boom hand-held CO2 sprayer (35 psi) with XULD 120-02 nozzles and water volume of 200 L Ha-1. Soak treatments were applied just prior to transplanting on June 6. Plug trays (288-cell size) were cut into 4 sections of 72 plants each. Each tray section was individually treated and used for one replicated plot. The moisture content was determined by removing five plugs of soilless mix from the tray and measuring percent water content using an Extech Soil Moisture Meter M0750 (Extech Instruments Corporation, Nashua, N.H.). Treatment solution (1.5 L) for each plot was placed in a kitty litter contained and each tray was soaked in the solution for one hour. After removing the tray from the solution, the remaining volume was recorded and the volume of solution absorbed by the section of transplant tray was calculated. The mean volume absorbed per plug was 6.2 mL for treatment Civitas 5% v/v+Harmonizer 5% v/v. In-furrow treatments were applied at the time of transplanting. The treatment solution was mixed in a 2 L bottle and applied using CO2 pressure. A nozzle (Lumark 015-F110) was installed in the transplant show, in front of the transplant kicker. Treatments were delivered at a rate of 540 mL Ha-1 (40.5 mL per twin row). Transplant water was also used at the time of planting at a rate of 2.4 L Ha-1.
The trial was inoculated with Xanthomonas campestris pv. vesicatoria (Group D) and Pseudomonas syringae pv. tomato on June 16 at a concentration of ˜106 CFU ml-1. Inoculum was applied using a hand-held 2 m CO2 boom sprayer with ULD 120-02 nozzles at a pressure of 35 psi, and water volume of 200 L Ha-1. Symptoms of bacterial disease began to appear in the trial within 10 days after inoculation, so the trial was not re-inoculated.
The trial was irrigated using a drip irrigation system as required throughout the growing season. Revus (mandipropamid) was applied on July 26 and August 7 for preventative protection from late blight.
Bacterial spot and bacterial speck was assessed on June 29, July 5, August 2, 8, and 16 by counting the number of infected leaves on five plants in each plot and estimating the percent defoliation. Percent defoliation was also estimated on September 12.
One application of Civitas+Harmonizer applied by soaking transplant trays in the product solution or applied in furrow, was as effective as three applications of the standard bacteriacide Kocide 2000.
Soil application of Civitas is effective against early blight of tomato. Early blight of tomato, caused by the fungus, Alternaria solani, can be the most common foliar disease of tomatoes in eastern North America. It can also be a serious problem on potato. Preliminary evidence shows that application of Civiatas to soil results in fewer leaf lesions due to tomato early blight and an approx. 10 fold increase in endophytiic bacteria living inside the roots of the tomato plants. There are at least four species of bacteria that are affected by Civitas in the tomato roots. See Table 19.
