Abstract
Description
TECHNICAL FIELD
[0001] This disclosure describes compositions comprising encapsulated clomazone and non-encapsulated clomazone. Methods for preparing these compositions are also described. Methods for controlling unwanted vegetation with these compositions are also described. BACKGROUND OF THE DISCLOSURE
[0002] Clomazone compositions generally balance crop safety and efficacy. Generally, encapsulated clomazone is more selective and thus safer, but less efficacious, than non-encapsulated clomazone. Additionally, both target crop injury and non-target crop injury (e.g., caused by spray drift) must be considered. These balancing considerations limit formulations containing clomazone. SUMMARY OF THE DISCLOSURE
[0003] It has been found herein that compositions comprising both encapsulated clomazone and non-encapsulated clomazone are safe and effective. Formulations of mixtures of encapsulated clomazone and non-encapsulated clomazone unexpectedly enhance safety such that non-target crop injury in the absence of a safener is comparable to non-target crop injury in the presence of a safener. In other words, ZC clomazone formulations (comprising mixtures of clomazone CS and clomazone SC) provide crop safety that is at least equal to, and generally greater than, the safety levels provided by traditional safeners with non-encapsulated clomazone (clomazone SC). Additionally, ZC clomazone formulations provide additional safety benefits to non-target plants by providing volatility control when applied to the soil and when non-target plants are exposed due to spray drift.
[0004] In compositions comprising both encapsulated clomazone and non-encapsulated clomazone, a safener is not strictly required. Compositions comprising both encapsulated clomazone and non-encapsulated clomazone in ZC formulations are effective and can be used in multiple forms.
[0005] Enhanced target crop safety can also be achieved by adding a safener to the clomazone ZC formulation. In these improved clomazone ZC formulations, the clomazone ZC formulation itself provides most of the safety effect.
[0006] In one embodiment, the present disclosure relates to a composition comprising: (i) encapsulated clomazone; (ii) non-encapsulated clomazone; and (iii) optionally additional active ingredients, wherein the composition does not comprise a safener.
[0007] In another embodiment, the present disclosure relates to a method for preparing a composition, the method comprising: I) encapsulating clomazone; and II) forming a mixture comprising: (i) the encapsulated clomazone; (ii) non-encapsulated clomazone; and (iii) optionally additional active ingredients, wherein the composition does not contain a safener.
[0008] In yet another embodiment, the present disclosure relates to a method for controlling undesired vegetation, the method comprising applying a composition comprising: (i) encapsulated clomazone; (ii) non-encapsulated clomazone; and (iii) optionally additional active ingredients to the undesired vegetation or its locus or to the soil or crop to prevent emergence or growth of the undesired vegetation, wherein the composition does not contain a safener.

[0015] This written description uses examples to illustrate the disclosure, including the best mode, and also enables any person skilled in the art to practice the disclosure, including making and using any composition or system and performing any incorporated method. The patentable scope of the disclosure is defined by the claims and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have elements that do not differ from the literal language of the claims, or if they include equivalent elements that do not differ materially from the literal language of the claims.
[0016] As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains,” “containing,” “characterized by,” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitations explicitly recited. For example, a composition, mixture, process, or method that comprises a series of elements is not necessarily limited to those elements but may include other elements not expressly listed or other elements inherent to such composition, mixture, process, or method.
[0017] The connecting phrase “consisting of” excludes any unrecited element, step, or ingredient. If used in a claim, this phrase renders the claim closed, excluding materials other than those recited, except for impurities ordinarily associated therewith. When the phrase “consisting of” appears in a clause of the claim body rather than immediately following the preamble, the phrase limits only the elements set forth in that clause; as a whole, the claim does not exclude other elements.
[0018] The connective "consisting essentially of" is used to define a composition or method that includes materials, steps, features, components, or elements other than those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristics of the claimed invention. The term "consisting essentially of" lies between "comprising" and "consisting of". The use of "consisting essentially of" in this document allows the applicant (as a lexicographer) to define the claimed invention by excluding any materials, steps, features, or methods that the applicant deems non-critical to the claimed invention but may be known in the prior art and otherwise could be included in the claimed invention, whether or not such inclusion or exclusion is specifically described in the specification. The sole purpose for which the applicant may exclude any material, step, feature, or method may be to exclude elements of the prior art that would affect the novelty of the claimed invention and thus its patentability. Thus, if the inclusion of any element of the prior art is detrimental to the patentability of the claimed invention, the use of "consisting essentially of" in this document does not require express support from the specification to exclude such element from the claimed invention.
[0019] When an invention or a part thereof is defined by an open-ended term such as "comprising", it should be understood (unless otherwise stated) that the description should also be interpreted as using the terms "consisting essentially of" or "consisting of" to describe such invention.
[0020] Furthermore, unless expressly stated to the contrary, "or" means inclusive or rather than exclusive or. For example, the condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or absent), A is false (or absent) and B is true (or present), and both A and B are true (or present).
[0021] In addition, the indefinite articles "a" and "an" preceding an element or component of the present invention are intended to be non-restrictive with respect to the number of instances (i.e., occurrences) of such element or component. Thus, "a" or "an" should be understood to include one or at least one, and the singular word form of an element or component also includes the plural, unless the number clearly means the singular. The term "optionally" associated with an ingredient or method in a formulation of the present invention may alternatively mean "present or absent". Unless otherwise stated or indicated, the "presence" or "absence" of an "optional" component is independent of the presence or absence of other formulation ingredients or steps.
[0022] As used herein, the term "about" provides an estimate of the value relevant to the claimed invention depending on the context in which it is used, where the estimate is reasonable when considered in conjunction with the description of the present invention and taking into account the information known from publicly available information, as such information would be understood or interpreted by a person of ordinary skill in the art. Generally, the term "about" as used herein means that the estimate will fall within plus or minus 10% of the relevant value. Clomazone is a herbicide recently introduced by FMC Corporation, and its CAS name is 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone. For convenience, clomazone is commercially sold as (as a formulated material) "Overwatch", and is also known as "DCPMI", "F9600", "2,4-DC", and "dichloroclomazone". In one embodiment, the clomazone may be industrial grade clomazone, where the purity ranges from 90% to 95% by weight. In another embodiment, the clomazone may be a composition comprising greater than 95% by weight of pure 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolinone. In another embodiment, "pure clomazone" means 100% pure 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolinone.
[0023] As used herein, "wt%" refers to the weight percentage of the component relative to the total weight of the composition.

[0164] Generally, the compositions according to the present disclosure comprise an effective amount of encapsulated clomazone and non-encapsulated clomazone. The effective amount of encapsulated clomazone and non-encapsulated clomazone is any amount that is capable of combating harmful plants while providing acceptable safety in the absence of a safener. The effectiveness of the compositions used in the methods for controlling harmful plants will depend on various factors such as the application mode, the harmful plants to be combated, the useful plants to be protected, the application time, etc. A person skilled in the art can readily determine the methods of using the effective compositions using well-known principles.
[0165] In many embodiments, the encapsulated clomazone and the non-encapsulated clomazone are present and / or are applied in a ratio of the effective amount of encapsulated clomazone and non-encapsulated clomazone. The ratio can be a weight ratio, a molar ratio, an application rate ratio, or a volume ratio. The ratio is preferably an application rate ratio. As used herein, the effective application ratio is effective against target weeds and is also safe for crops.
[0166] In some embodiments, the encapsulated clomazone is used in an amount of about 1 g / ha, about 10 g / ha, about 50 g / ha, about 100 g / ha, about 200 g / ha, about 300 g / ha, about 400 g / ha, about 500 g / ha, about 600 g / ha, about 700 g / ha, about 800 g / ha, about 900 g / ha, about 1000 g / ha, about 1100 g / ha, about 1200 g / ha, about 1300 g / ha, about 1400 g / ha, about 1500 g / ha, about 1600 g / ha, about 1700 g / ha, about 1800 g / ha, about 1900 g / ha, about 2000 g / ha, about 2100 g / ha, about 2200 g / ha, about 2300 g / ha, about 2400 g / ha, about 2500 g / ha, about 2600 g / ha, about 2700 g / ha, about 2800 g / ha, about 2900 g / ha, about 3000 g / ha, or greater than about 3000 g / ha to about 10 g / ha, about 50 g / ha, about 100 g / ha, about 200 g / ha, about 300 g / ha, about 400 g / ha, about 500 g / ha, about 600 g / ha, about 700 g / ha, about 800 g / ha, about 900 g / ha, about 1000 g / ha, about 1100 g / ha, about 1200 g / ha, about 1300 g / ha, about 1400 g / ha, about 1500 g / ha, about 1600 g / ha, about 1700 g / ha, about 1800 g / ha, about 1900 g / ha, about 2000 g / ha, about 2100 g / ha, about 2200 g / ha, about 2300 g / ha, about 2400 g / ha, about 2500 g / ha, about 2600 g / ha, about 2700 g / ha, about 2800 g / ha, about 2900 g / ha, about 3000 g / ha, or greater than about 3000 g / ha. However, higher and lower application rates may also provide adequate control.
[0167] In some embodiments, the unencapsulated clomazone is used in an amount of about 1 g / ha, about 10 g / ha, about 50 g / ha, about 100 g / ha, about 200 g / ha, about 300 g / ha, about 400 g / ha, about 500 g / ha, about 600 g / ha, about 700 g / ha, about 800 g / ha, about 900 g / ha, about 1000 g / ha, about 1100 g / ha, about 1200 g / ha, about 1300 g / ha, about 1400 g / ha, about 1500 g / ha, about 1600 g / ha, about 1700 g / ha, about 1800 g / ha, about 1900 g / ha, about 2000 g / ha, about 2100 g / ha, about 2200 g / ha, about 2300 g / ha, about 2400 g / ha, about 2500 g / ha, about 2600 g / ha, about 2700 g / ha, about 2800 g / ha, about 2900 g / ha, about 3000 g / ha, or greater than about 3000 g / ha to about 10 g / ha, about 50 g / ha, about 100 g / ha, about 200 g / ha, about 300 g / ha, about 400 g / ha, about 500 g / ha, about 600 g / ha, about 700 g / ha, about 800 g / ha, about 900 g / ha, about 1000 g / ha, about 1100 g / ha, about 1200 g / ha, about 1300 g / ha, about 1400 g / ha, about 1500 g / ha, about 1600 g / ha, about 1700 g / ha, about 1800 g / ha, about 1900 g / ha, about 2000 g / ha, about 2100 g / ha, about 2200 g / ha, about 2300 g / ha, about 2400 g / ha, about 2500 g / ha, about 2600 g / ha, about 2700 g / ha, about 2800 g / ha, about 2900 g / ha, about 3000 g / ha, or greater than about 3000 g / ha. However, higher and lower application rates may also provide adequate control.
[0168] The application rate of the composition will vary depending on primary conditions such as the target weed, degree of infestation, weather conditions, soil conditions, crop type, application pattern, and time of application. The composition containing the active compound can be applied in the form in which it is formulated. In the practice of the present disclosure, as when a formulator prepares a formulation, the application rates of the encapsulated clomazone and the unencapsulated clomazone can vary independently of each other, provided that each of these components is applied within the disclosure scope of the present disclosure.
[0169] The compositions according to the present disclosure can be in the form of any suitable agrochemical composition known in the art. A particularly preferred formulation of the compositions according to the present disclosure is a mixture (ZC) of a suspension concentrate (SC) and a capsule suspension concentrate (CS) formulation. The acronym "SC" means a suspension concentrate (a stable suspension of one or more active ingredients with water as the fluid); "ZC" refers to a mixed formulation of CS and SC (a stable suspension of capsules and one or more active ingredients in a fluid, usually intended to be diluted with water before use).
[0170] The agrochemical compositions can be applied in various combinations of two active compounds. For example, they can be applied as a single "premix" form, or as a combined spray mixture consisting of separate formulations of the active compounds (e.g., in the form of a "tank mix"). Thus, for combined use, it is not necessary to apply the two active compounds in a physically combined form or even simultaneously, i.e., these components can be applied separately and / or sequentially, provided that the application of the second active compound occurs within a reasonable time period from the application of the first active compound. As long as the two active compounds are present simultaneously, the combined effect will occur, regardless of when they are applied. Thus, for example, a physical combination of the two active compounds can be applied, or one can be applied earlier than the other, as long as at the time of application of the second active compound, the earlier applied active compound is still present on the harmful plants to be controlled or in the soil around the harmful plants to be controlled, and as long as the weight ratio of the available active compounds falls within the ranges provided herein. The order of application of the components, the encapsulated clomazone and the non-encapsulated clomazone, is not important. Similarly, any form of combination of the active components can be applied for pre-emergence or post-emergence control of harmful plants (e.g., weeds in useful plant crops).
[0171] The compositions according to the present disclosure can be formulated with other suitable formulation components known in the art. As non-limiting examples, the compositions according to the present disclosure can be formulated using known adjuvants, auxiliaries, diluents, solvents, dispersants, surfactants, protective colloids, thickeners, penetrants, stabilizers, chelating agents, anti-caking agents, colorants, pigments, corrosion inhibitors, biocides, defoamers, antifreeze agents, rheology modifiers, and combinations thereof.
[0172] As used herein, the term surfactant means an agriculturally acceptable material that imparts emulsifying, stabilizing, spreading, wetting, dispersing, or other surface-modifying properties. Examples of suitable surfactants include lignosulfonates, fatty acid sulfonates (e.g., lauryl sulfonate), condensation products of formaldehyde and naphthalenesulfonates, alkylaryl sulfonates, ethoxylated alkylphenols, and ethoxylated fatty alcohols. Other known surfactants that have been used with herbicides are also acceptable.
[0173] Suitable diluents may be added during the formulation process, after the formulation process (e.g., by the user - farmer or custom applicator), or both. The term diluent includes all liquid and solid carriers containing agriculturally acceptable materials which may be added to the herbicide to bring it into a suitable form for application or commerce and includes solvents, emulsifiers, and dispersants. Examples of suitable solid diluents or carriers are aluminum silicate, talc, calcined magnesia, kieselguhr, tricalcium phosphate, powdered cork, absorbent carbon black, chalk, silica, and clays (such as kaolin and bentonite). Examples of suitable liquid diluents include water, organic solvents (e.g., acetophenone, cyclohexanone, isophorone, toluene, xylene, petroleum fractions), amines (e.g., ethanolamine, dimethylformamide), and mineral, animal, and vegetable oils (used alone or in combination).
[0174] The compositions according to the present disclosure may also be formulated with additional suitable additional active ingredients known in the art. If it is desired to broaden the control spectrum or prevent the build - up of resistance, additional herbicides may be utilized.
[0175] Examples of additional active ingredients are: acetochlor, acifluorfen and its sodium salt, acibenzolar, acrolein (2-propenal), alachlor, alloxydim, ametryn, amicarbazone, amidosulfuron,

[0224]
[0225] This example shows the higher safety of encapsulated clomazone towards non-target plants compared to non-encapsulated clomazone.
[0226] Example 4. Volatility effects of encapsulated and non-encapsulated clomazone formulations when applied to bare soil.
[0227] A greenhouse study was conducted to determine the area of effect of the volatility of various herbicides on Stellaria at 1000 g ai / ha. Before starting the test, 7.5 cm flower pots were filled with metro mix and sown with Stellaria. Stellaria grew until the flower pot was completely covered with leaves. Each herbicide treatment was repeated with 3 separate rings and included 3 untreated controls. At 10 cm2 Herbicide treatments were applied to Matapeake soil in plastic flower pots. The treatments were applied using compressed air in an orbital spray chamber at 280 L / ha (30 gallons / acre) using TeeJet 8001E nozzles at 275 kPa (40 psi) (SOP#901). Each flower pot was covered with plastic immediately after application.
[0228] Once all treatments were applied, the treated flower pots were moved to the greenhouse. One treated flower pot was placed at the center of each chickweed ring, and then the plastic covering was removed. During the test, no overhead watering was applied to any of the plants or flower pots. Water and fertilizer to maintain chickweed growth were applied by subsurface irrigation. For each chickweed spoke, the measurement (cm) of the volatile capturing the farthest visual observation from the center of the spoke (center of the 10 cm treated flower pot) was recorded. Evidence of volatilization was recorded as chlorosis on the chickweed leaves. Eight measurements were taken for each ring on each observation date. The data were analyzed using Minitab statistical software with 95% confidence intervals.
[0229] The data for this test are in the table below. DAT represents days after treatment.
[0230] Table 4. Greenhouse test.
[0231]
[0232] *Values sharing the same letter in a column are not statistically different
[0233] No cross - contamination was observed in this greenhouse test, which was determined by the complete absence of visible chlorosis on any of the chickweed plants for the untreated control rings. In the first rating interval, all herbicide treatments showed signs of volatilization. As the study progressed, the chlorotic area for all treatments gradually increased. For the clomazone compositions, at 10 DAT, F9600 - 4 (clomazone SC) affected the largest area and clomazone ZC volatilized the least.
[0234] Example 5. Phytotoxicity study.
[0235] The phytotoxicity of encapsulated and non - encapsulated clomazone compositions to winter wheat was evaluated. The compositions were applied pre - emergence and early post - emergence.
[0236] The results of this example are shown in Figures 1 to 4 (FIGURE 1 to FIGURE 4). The numbers in parentheses indicate the equivalent concentration of the compositions applied. It was determined that the safener had little or no effect compared to the clomazone compositions without the safener. 2wAA means two weeks after application and BBCH 21 - 29 means the tillering stage of cereals.
[0237] Example 6. Crop Injury Study.
[0238] The maximum crop injury of encapsulated and non-encapsulated clomazone compositions to corn was evaluated. The compositions were applied after sowing, pre-emergence, and post-emergence.
[0239] The results of this example are shown in Figures 5 - 6 . The numbers in parentheses indicate the application rates of the compositions applied (in gai / ha).
[0240] In Figure 5 , it was determined that at the post-emergence time of BBCH 11 - 12, the injury to the crop by clomazone ZC and F4205 - 11 was acceptable. BBCH 11 - 12 means one to two true leaves of the crop. The symptoms observed were mainly leaf albino / chlorosis, and dwarfing was occasionally seen at 375 g ai / ha. These symptoms were always transient and there was no obvious crop response in 2 out of 6 trials. The mixture containing Adengo Xtra (containing cyprosulfamide) showed reduced crop injury. However, no effect was observed on cloquintocet.
[0241] In Figure 6 , it was determined that at the post-emergence time of BBCH 13 - 15, the injury to the crop by clomazone ZC (250 and 375 g ai / ha) and F4205 - 11 was unacceptable. BBCH 13 - 15 means three to five true leaves of the crop. The symptoms observed were mainly leaf albino / chlorosis, and dwarfing was occasionally seen. These symptoms were always transient, even more persistent compared to the early stage after crop emergence, and there was no obvious crop response in 2 out of 6 trials. The mixture containing Adengo Xtra (containing cyprosulfamide) showed reduced crop injury. This was mainly visible at high doses. However, no effect was observed on cloquintocet.
