Description

Technical Field

[0001] This invention relates to a method for controlling weeds using columnar crystals of sulfonylpyrazole. More specifically, it relates to a method for controlling weeds in which a high degree of weed control can be achieved by applying sulfonylpyrazole crystals of the described shape to soil having a specific soil texture. Background Technology

[0002] Sulfonazole is a well-known herbicidal active ingredient (Patent Document 1) and is commercially available in many countries, including Japan. It is known to have high herbicidal efficacy against grassy weeds such as barnyard grass, crabgrass, foxtail grass, Kentucky bluegrass, rockgrass, wild oats, Italian ryegrass, Swiss ryegrass, wild oats, and wild oats. It also exhibits high herbicidal efficacy against broadleaf weeds such as amaranth, sorrel, lambsquarters, chickweed, velvetleaf, purslane, Colorado river hemp, ragweed, morning glory, crape myrtle, speedwell, ivy, violet, sedge, oil sedge, scorpionless scales, awned sedge, and sedge, as well as perennial and annual awned sedge weeds such as sedge, oil sedge, scorpionless scales, awned sedge, and sedge. It also has a broad spectrum of herbicidal activity (Non-Patent Document 1).

[0003] Generally speaking, soil treatment is one of the effective herbicide application methods in drylands. Although it can be expected to control pests for a long time, the effectiveness of weed control can vary depending on the environmental conditions after treatment. For example, soil type and rainfall after herbicide treatment are the main reasons for the variation in weed control effectiveness. Depending on the combination of soil type and rainfall, the weed control effect can sometimes be reduced.

[0004] On the other hand, regarding sulfonylpyrazole, crystals exhibiting different characteristics, such as columnar and needle-like shapes, can be obtained through different manufacturing methods. Furthermore, it is known that different hydration properties, redispersibility, etc., can be observed depending on the shape of the crystal (Patent Document 2).

[0005] However, it is unknown that the different crystal shapes of sulfopyrazole would cause differences in herbicidal efficacy.

[0012] The technical problem that the invention aims to solve

[0013] The purpose of this invention is to provide a method for more effective weed control when soil treatment is performed with sulfopyrazole.

[0014] Technical means to solve technical problems

[0015] The inventors conducted in-depth research and discovered that the aforementioned technical problem could be solved by treating soil composed of specific components with columnar sulfonium pyrazol, thus completing the present invention.

[0021] Invention Effects

[0022] According to the present invention, soil treatment with sulfonylpyrazole under given conditions can provide a higher herbicidal effect. Detailed Implementation

[0023] Regarding the pyroxasulfone used in this invention, the name is the ISO name (a generic name based on the International Standardized Structure), and its chemical name is 3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole.

[0024] As for the crystal shapes of sulfonylpyrazole, two types are known: needle-shaped crystals and columnar crystals. Patent Document 2 discloses these shapes and their respective manufacturing methods. Here, a columnar crystal shape refers to a crystal in which, when a rectangle is inscribed in the orthographic projection of the crystal being observed, the ratio of the length of the shorter side to the length of the longer side of the rectangle is 1:1 to 1:10, preferably 1:1 to 1:5. Furthermore, a needle-shaped crystal shape refers to a crystal in which the length of the longer side of the rectangle is more than 10 times the length of the shorter side. The shape of the sulfonylpyrazole crystals can be observed using optical microscopes, electron microscopes, etc., and the observation method is not particularly limited. In the columnar crystals of sulfonylpyrazole used in this invention, needle-shaped crystals may be mixed in; when randomly observing 10 of them, it is preferable that 8 or more crystals are columnar in shape.

[0025] The columnar crystals of sulfonylpyrazole used in this invention can be obtained by methods such as concentration, addition of unsuitable solvents, vapor diffusion (including sitting drop, hanging drop, and sandwich drop), batch processing (including oil batch processing), dialysis, liquid-liquid diffusion (reverse diffusion), cooling, pressure, melt quenching (melt quenching), temperature cycling, slurry stirring, and ultrasonic methods, among other known crystallization techniques. As a preferred embodiment, the method for obtaining the columnar crystals of sulfonylpyrazole of this invention includes a concentration method, i.e., a method of distilling away the organic solvent from a sulfonylpyrazole solution comprising a solvent mainly composed of an organic solvent and sulfonylpyrazole as a solute, thereby precipitating sulfonylpyrazole. As another preferred embodiment, the method for obtaining the columnar crystals of sulfonylpyrazole of this invention includes an addition of unsuitable solvents, i.e., a method of adding an unsuitable solvent to a sulfonylpyrazole solution comprising a solvent mainly composed of an organic solvent and sulfonylpyrazole as a solute, thereby precipitating sulfonylpyrazole.

[0026] Distillation removal refers to the removal of organic solvents constituting the solvent from the solution by evaporation or boiling, either partially or completely. If the organic solvent constituting the sulfonylpyrazole solution is removed by distillation, the solution becomes concentrated and supersaturated, and the excess sulfonylpyrazole relative to the solvent precipitates out as crystals. Distillation removal can be carried out at atmospheric pressure or, if necessary, under reduced or increased pressure. Furthermore, distillation removal can be carried out at room temperature or by heating or cooling the system as needed.

[0027] Furthermore, a poor solvent refers to a solvent with low solubility for the solute. If a poor solvent is added to the solvent constituting the sulfonylpyrazole solution, the solubility of sulfonylpyrazole decreases with increasing amount of poor solvent, becoming supersaturated. Excess sulfonylpyrazole relative to the solvent precipitates out as crystals. The addition of a poor solvent can be carried out at room temperature, or by heating or cooling the system as needed.

[0028] In any of the methods described, in obtaining the columnar crystals of sulfonylpyrazine of the present invention, not all organic solvents can be used arbitrarily; the selection of the organic solvent is extremely important. If the organic solvent is chosen incorrectly, columnar crystals of sulfonylpyrazine with the characteristic pattern confirmed in the desired powder X-ray diffraction spectrum cannot be obtained.

[0029] In the method of precipitating sulfonylpyrazol of the present invention by distilling away the organic solvent, the organic solvent that can be used includes at least: aromatic hydrocarbon derivatives (e.g., benzene, toluene, xylene, chlorobenzene, dichlorobenzene, trichlorobenzene, nitrobenzene, etc.), halogenated aliphatic hydrocarbons (e.g., dichloromethane, tetrachloroethylene, etc.), alcohols (e.g., methanol, ethanol, isopropanol, butanol, tert-butanol, etc.), nitriles (e.g., acetonitrile, propionitrile, etc.), carboxylic acids (formic acid, acetic acid, propionic acid, butyric acid, etc.), carboxylic acid esters (e.g., methyl acetate, ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate and its isomers, pentyl acetate and its isomers, etc.), ethers (e.g., tetrahydrofuran, 2-methyltetrahydrofuran, 1,4-dioxane, diisopropyl ether, dibutyl ether, ditert-butyl ether, cyclopentyl methyl ether, methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether). This includes methyl methacrylate (MCMA), ketones (e.g., methyl isopropyl ketone, methyl isobutyl ketone), amides (e.g., N,N-dimethylformamide, N,N-dimethylacetamide), ureas (e.g., N,N'-dimethylimidazolinone, tetramethylurea), sulfoxides (e.g., diethyl sulfoxide), sulfones (e.g., sulfolane), and any combination thereof in any proportion. Particularly nitriles, carboxylic acids, carboxylic acid esters, ketones, amides, and dihaloaliphatic hydrocarbons.

[0030] The preferred organic solvents mentioned above include: C2-C5 alkane nitriles, C1-C4 carboxylic acids, C1-C4 alkyl C1-C4 carboxylic esters, C1-C4 alkyl C1-C4 alkyl ketones, N,N-bis(C1-C4 alkyl)C1-C4 alkane amides, and C1-C4 dihaloalkanes. Particularly acetonitrile, acetic acid, ethyl acetate, methyl isobutyl ketone, N,N-dimethylformamide, N,N-dimethylacetamide, and dichloromethane.

[0031] In the described method, the solvent constituting the sulfonylpyrazole solution may also be an aqueous solvent that also contains water. However, from the viewpoint of ensuring sufficiently high solubility of sulfonylpyrazole in the aqueous solvent, it is preferable to include an organic solvent as the main component. It should be noted that, in this specification, including a component as a main component means that the volume of that component accounts for more than one-third of the total volume of all components constituting the composition under discussion.

[0032] The preferred solvents described above include: C1-C4 alcohol / C2-C5 alkane nitrile mixed solvents, aqueous C2-C5 alkane nitriles, C1-C4 carboxylic acids, C1-C4 alkyl C1-C4 carboxylic esters, N,N-di(C1-C4 alkyl)C1-C4 alkane amides, and C1-C4 dihaloalkane / C1-C4 alcohol mixed solvents. Particularly preferred are acetonitrile / methanol mixed solvents, aqueous acetonitrile, acetic acid, ethyl acetate, methyl isobutyl ketone, N,N-dimethylformamide, N,N-dimethylacetamide, and dichloromethane / ethanol mixed solvents.

[0033] On the other hand, the organic solvents mentioned above that should be avoided when used alone include: chloroform, dimethyl sulfoxide, 1,4-dioxane, 2-methyltetrahydrofuran, N-methylpyrrolidone, tetrahydrofuran, trifluoroethanol, and carbon disulfide. However, the use of these organic solvents in combination with other organic solvents, or in aqueous solvents containing these organic solvents and water, is not excluded.

[0034] In the method of precipitating columnar crystals of sulfopyrazole of the present invention by adding an unsuitable solvent, the organic solvent that can be used includes at least: aromatic hydrocarbon derivatives (e.g., benzene, toluene, xylene, chlorobenzene, dichlorobenzene, trichlorobenzene, nitrobenzene, etc.), halogenated aliphatic hydrocarbons (e.g., dichloromethane, tetrachloroethylene, etc.), alcohols (e.g., methanol, ethanol, isopropanol, butanol, tert-butanol, etc.), nitriles (e.g., acetonitrile, propionitrile, etc.), carboxylic acids (formic acid, acetic acid, propionic acid, butyric acid, etc.), carboxylic acid esters (e.g., methyl acetate, ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate and its isomers, pentyl acetate and its isomers, etc.), and ethers. Classes of ureas (e.g., tetrahydrofuran, 1,4-dioxane, diisopropyl ether, dibutyl ether, di-tert-butyl ether, cyclopentyl methyl ether, methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, etc.), ketones (e.g., acetone, methyl ethyl ketone, methyl isopropyl ketone, methyl isobutyl ketone, etc.), amides (e.g., N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, etc.), ureas (e.g., N,N'-dimethylimidazolinone, tetramethylurea, etc.), sulfoxides (e.g., dimethyl sulfoxide, diethyl sulfoxide, etc.), sulfones (e.g., sulfolane, etc.), and any combination thereof in any proportion. Nitriles, ketones, and carboxylic acid esters are particularly important.

[0035] The preferred organic solvents mentioned above include C2-C5 alkane nitriles and C1-C4 alkyl C1-C4 carboxylic esters. Acetonitrile, acetone, and ethyl acetate are particularly preferred.

[0036] In the described method, the solvent constituting the sulfonylpyrazole solution may also be an aqueous solvent that also contains water. However, from the viewpoint of ensuring sufficiently high solubility of sulfonylpyrazole in the aqueous solvent, it is preferable to include an organic solvent as the main component.

[0037] In this method, the unsuitable solvent refers to a solvent with a solubility of sulfonylpyrazine of less than 50 g / L at 20°C, and includes at least: ethers (diethyl ether, methyl tert-butyl ether, anisole, 2-methyltetrahydrofuran, etc.), carboxylic acid esters (isopropyl acetate, etc.), ketones (methyl isobutyl ketone, etc.), aliphatic hydrocarbons (cyclohexane, heptane, etc.), alcohols (methanol, ethanol, propanol, isopropanol, butanol, isobutanol, tert-butanol, etc.), aromatic hydrocarbon derivatives (toluene, xylene, etc.), and water. Alcohols are particularly important.

[0038] The preferred unsuitable solvent is one that is compatible with the solvent constituting the sulfonylpyrazole solution. Furthermore, C1-C4 alcohols are preferred, ethanol or isopropanol are even more preferred, and ethanol is particularly preferred.

[0039] Among the combinations of solvents and undesirable solvents constituting the sulfonylpyrazole solution, particularly preferred combinations include: acetonitrile and ethanol, acetone and ethanol, and ethyl acetate and ethanol.

[0040] In any of the aforementioned cases, seed crystals may also be used when obtaining columnar crystals of sulfopyrazole of the present invention.

[0041] In one embodiment, the sulfonylpyrazole solution can be a reaction solution used in the synthesis of sulfonylpyrazole. The method for synthesizing sulfonylpyrazole is not particularly limited and can be carried out according to known methods. Preferably, the method for synthesizing sulfonylpyrazole includes step (iii) of Patent Document 2.

[0042] The columnar crystals of sulfonylpyrazol thus obtained, in powder X-ray analysis based on transmission using Cu-Kα rays, show spectra with peaks at diffraction angles 2θ in the range of at least 17.8–17.9°, 18.0–18.1°, and 19.9–20.0°, preferably with the highest peak height at 19.9–20.0°.

[0043] When using sulfopyrazine columnar crystals as the active herbicidal ingredient, the crystals can be used alone. However, from the perspectives of safety and convenience, it is preferable to process them into pesticide compositions, i.e. pesticide formulations, that are blended with various pesticide adjuvants for use.

[0044] The columnar crystals of sulfonylpyrazole used in this invention can be processed into various formulations of pesticide formulations using known and conventional formulation techniques.

[0074] Soil treated by the method of the present invention is preferably moist. Specifically, after soil treatment with columnar crystals of sulfonylpyrazole, the cumulative rainfall on the soil within 7 days is preferably 15 mm or more, more preferably 30 mm or more, and particularly preferably 45 mm or more.

[0075] In the weed control method of the present invention, there is no particular limitation on the cultivated crop, but crops that can be cultivated in dry land are preferred. For example, suitable crops include corn, rice, wheat, durum wheat, barley, rye, triticale, spelt wheat, high-ear wheat, oats, sorghum, cotton, soybean, alfalfa, peanut, common bean, lima bean, red bean, cowpea, mung bean, lentil, red adzuki bean, moth bean, broad bean, broad bean, pea, chickpea, lentil, lupin, pigeon pea, buckwheat, sugar beet, rapeseed, canola, sunflower, sugarcane, cassava, yam, oil palm, jatropha, hemp, flax, quinoa, safflower, tea tree, mulberry, tobacco, etc.

[0076] Furthermore, the cultivated crop varieties used in the weed control method of the present invention are not particularly limited, and include plants resistant to 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) inhibitors such as isoxaflutole, sulfadiazine, mesotrione, and pyrazosulfuron; acetolactate synthase (ALS) inhibitors such as imazalil, methoxyimazalil, thiencarbazone, thifensulfuron, and bensulfuron; 5-enolpyruvate-3-phosphate (EPSP) synthase inhibitors such as glyphosate; glutamine synthase inhibitors such as glufosinate; acetyl-CoA carboxylase (ACCase) inhibitors such as quizalofop-P-ethyl and quizalofop-P-ethyl; protoporphyrinogen oxidase (PPO) inhibitors such as propyzamide and epyrifenacil; photochemical class II inhibitors such as bromobenzonitrile; and herbicides such as dicamba and 2,4-D, induced by classical breeding methods and gene recombination technology.

[0077] Examples of crops that have been acclimated to resistance through classic breeding methods include rapeseed, wheat, sunflower, rice, and corn that are resistant to imidazolinone ALS-inhibiting herbicides such as imidazolinone, and are commercially available under the trade name Clearfield (registered trademark).

[0078] Similarly, soybeans resistant to sulfonylurea ALS-inhibiting herbicides such as thifensulfuron exist through classical breeding methods and are commercially available under the trade name STS soybeans. Likewise, sorghum resistant to sulfonylurea acetolactate synthase (ALS)-inhibiting herbicides has been commercially available through classical breeding methods. Similarly, sugar beets resistant to thiencarbazone-resistant acetolactate synthase (ALS)-inhibiting herbicides have been commercially available through classical breeding methods. Likewise, examples of useful plants resistant to acetyl-CoA carboxylase (ACCase) inhibitors such as triketoximes and aryloxyphenoxypropionic acid herbicides through classical breeding methods include SR corn (also known as "PoastProtected corn") and quizalofop-p-ethyl-resistant wheat. Plants conferred resistance to acetyl-CoA carboxylase (ACCase) inhibitors have been documented in "Proceedings of the National Academy of Science of the United States of America," Vol. 87, pp. 7175-7179 (1990), etc. Furthermore, mutant acetyl-CoA carboxylase (ACCase) resistant to acetyl-CoA carboxylase inhibitors have been reported in "Weed Science," Vol. 53, pp. 728-746 (2005), etc. Plants resistant to acetyl-CoA carboxylase inhibitors can be prepared by introducing such mutant acetyl-CoA carboxylase genes into plants using gene recombination technology, or by introducing resistance-conferred mutations into crop acetyl-CoA carboxylase (ACCase). In addition, by introducing base substitution mutations, represented by the chimera repair technique described in "Repairing the Genome's Spelling Mistakes" ("Science" Vol. 285: pp. 316-318 (1999, by Gura T.)), into nucleic acids and causing site-specific amino acid substitution mutations in the crop gene (acetyl-CoA carboxylase (ACCase) / herbicide target), plants resistant to acetyl-CoA carboxylase (ACCase) inhibitors / herbicides can be produced.

[0079] Examples of useful plants that have been conferred resistance through genetic recombination technology include glyphosate-resistant varieties of corn, soybeans, cotton, rapeseed, sugar beets, and alfalfa, which are commercially available under trade names such as Roundup Ready, Roundup Ready 2, and AgrisureGT. Similarly, glufosinate-resistant varieties of corn, soybeans, cotton, and rapeseed based on genetic recombination technology are commercially available under trade names such as LibertyLink. Likewise, cotton resistant to bromobenzonitrile based on genetic recombination technology is commercially available under the trade name BXN. Similarly, soybeans resistant to HPPD inhibitors based on genetic recombination technology, as varieties resistant to mesotrione and glufosinate, are commercially available under the trade name Herbicide-tolerant Soybean line; furthermore, varieties resistant to HPPD inhibitors, glyphosate, and glufosinate are commercially available under trade names such as Credenz. Similarly, corn, soybeans, and cotton resistant to 2,4-D or ACCase inhibitors based on recombinant gene technology are already commercially available under trade names such as Enlist (registered trademark). Likewise, soybeans resistant to dicamba based on recombinant gene technology are commercially available under trade names such as Roundup Ready2Xtend (registered trademark). Similarly, a soybean variety resistant to HPPD inhibitors such as isoxaflutole and nematodes, developed through recombinant gene technology, has been registered in the United States as GMB151.

Beans, melons, millet, oats, rapeseed, potatoes, rice, rye, sorghum, soybeans, sugar beets, sunflowers, tobacco, tomatoes, and wheat (e.g., see US5013659, WO2006 / 060634, US4761373, US5304732, US6211438, US6211439, and US6222100), especially rice resistant to imidazolinone herbicides, are known to have specific variations in the acetolactate synthase gene (e.g., Rice (e.g., see US2003 / 0217381A, WO2005 / 020673) resistant to diketone nitrile decomposition products of HPPD-inhibiting herbicides (e.g., isoxazolidinone, triketone herbicides such as isoxazolidinone, mesotrione, and pyrazole herbicides such as pyrazosulfuron-methyl) or isoxazolidinone, as well as barley, sugarcane, and water crops resistant to diketone nitrile decomposition products of isoxazolidinone (S653N, S654K, A122T, S653(At)N, S654(At)K, A122(At)T). Rice, corn, tobacco, soybean, cotton, rapeseed, sugar beet, wheat, and potato (e.g., see WO2004 / 055191, WO1996 / 038567, WO1997 / 049816, and US6791014), and wheat, soybean, cotton, sugar beet, rapeseed, rice, corn, sorghum, sugarcane, and sugar beet resistant to PPO herbicides (e.g., see US2002 / 0073443A, US2008 / 0052798A, Pesto Management Science, Vol. 61: pp. 277-285 (2005)).

[0081] Plants accrued with herbicide resistance through existing varietal improvement or genomic breeding techniques include, for example: rice "Clearfield Rice," wheat "Clearfield Wheat," sunflower "Clearfield Sunflower," lentils, and canola resistant to imidazolinone ALS-inhibiting herbicides such as imidacloprid and methoxypromethazine; soybean "STS soybean" resistant to sulfonylurea ALS-inhibiting herbicides such as thifensulfuron-methyl; and corn "SR" resistant to acetyl-CoA carboxylase inhibitors such as triketone oxime and aryloxyphenoxypropionic acid herbicides. The following rice varieties are listed: "ExpressSun" (registered trademark), a sunflower resistant to sulfonylurea herbicides such as bensulfuron-methyl; "Provisia Rice" (registered trademark), a rice resistant to acetyl-CoA carboxylase inhibitors such as quizalofop-P-ethyl; "Triazine Tolerant Canola" (registered trademark), a canola resistant to photochemical class II herbicides; and "Igrowth" (registered trademark), a sorghum resistant to imidazolinone herbicides.

[0082] As an example of a plant conferred herbicide resistance through genome editing technology, SU Canola (registered trademark), which exhibits resistance to sulfonylurea herbicides, is an example of this technology. Genome editing technology refers to the sequence-specific conversion of genetic information, capable of base deletions, amino acid substitutions, and the introduction of foreign genes. RTDS (registered trademark) is equivalent to the targeted oligonucleotide mutation introduction in genome editing technology. It is a technique that introduces mutations without cutting the plant's DNA through Gene Repair OligoNucleotide (GRON), a chimeric oligonucleotide combining DNA and RNA. Other examples include maize with reduced herbicide resistance and phytic acid content by using zinc finger nucleases to delete the endogenous gene IPK1 (e.g., see Nature, Vol. 459: pp. 437-441 (2009)) and rice with herbicide resistance conferred by CRISPR-Cas9 (e.g., see Rice, Vol. 7: pp. 5 (2014)).

[0083] Plants that have been conferred herbicide resistance through new breeding techniques include, for example, soybeans that have been grafted using varietal improvement techniques to impart properties to GM rootstocks. Specifically, examples include Roundup Ready (registered trademark) which has glyphosate resistance, and soybeans that have been grafted onto non-GMO soybean scions using soybean as rootstock to confer glyphosate resistance (see "Weed Technology", Vol. 27, p. 412 (2013)).

[0084] The term "useful plants" also includes plants obtained using gene recombination technology that have the ability to synthesize, for example, selective toxins known in the genus Bacillus.

[0085] Examples of insecticidal toxins expressed in such genetically recombinant plants include: insecticidal proteins derived from *Bacillus cereus* and *Bacillus popilliae*; δ-endotoxin proteins such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry14Ab-1, Cry2Ab, Cry3A, Cry3Bb1, or Cry9C, and insecticidal proteins such as VIP1, VIP2, VIP3, or VIP3A, derived from *Bacillus thuringiensis*; insecticidal proteins derived from nematodes; toxins produced by animals such as scorpion venom, spider venom, bee venom, or insect-specific neurotoxins; filamentous fungal toxins; and plant lectins. lectin; agglutinin; protease inhibitors such as trypsin inhibitors, serine protease inhibitors, patatin, cysteine ​​protease inhibitors, and papain inhibitors; ribosome-inactivating proteins (RIPs) such as ricin, zeaxanthin, abryodin, and others; steroid metabolic enzymes such as 3-hydroxysteroid oxidase, ecdysteroid-UDP-glucosyltransferase (EGT), and cholesterol oxidase; ecdysone inhibitors; HMG-CoA reductase; ion channel inhibitors such as sodium channel inhibitors and calcium channel inhibitors; juvenile hormone esterase; diuretic hormone receptor; stilbene synthase; bibenzyl synthase; chitinase; and glucanase.

[0086] Toxins expressed in such genetically recombinant plants also include: hybrid toxins of δ-endotoxin proteins such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry14Ab-1, Cry2Ab, Cry3A, Cry3Bb1, Cry9C, Cry34A, Cry34Ab, or Cry35Ab; insecticidal proteins such as VIP1, VIP2, VIP3, or VIP3A; partially deleted toxins; and modified toxins. Hybrid toxins are produced by using gene recombination technology to create new combinations of different domains of such proteins. As partially deleted toxins, Cry1Ab with a partial amino acid sequence deletion is known. As modified toxins, one or more amino acids of the naturally occurring toxin are substituted.

[0087] Examples of these toxins and recombinant plants capable of synthesizing them are described, for instance, in patent documents such as EP0374753A, WO93 / 007278, WO95 / 034656, EP0427529A, EP0451878A, and WO03 / 052073. The toxins contained in these recombinant plants confer resistance, particularly against Coleoptera, Diptera, and Lepidoptera pests.

[0088] In addition, several commercially available recombinant plants containing one or more insecticidal pest resistance genes and expressing one or more toxins are known. Examples of these recombinant plants include: YieldGard (a registered trademark) maize variety expressing Cry1Ab toxin, YieldGard Rootworm (a registered trademark) maize variety expressing Cry3Bb1 toxin, YieldGard Plus (a registered trademark) maize variety expressing both Cry1Ab and Cry3Bb1 toxins, Herculex I (a registered trademark) maize variety expressing Cry1Fa2 toxin and glufosinate N-acetyltransferase (PAT) for conferring resistance to glufosinate, NuCOTN33B (a registered trademark) cotton variety expressing Cry1Ac toxin, and Bolgard I (a registered trademark) cotton variety expressing Cry1Ac toxin. II <Registered Trademark> (cotton varieties expressing Cry1Ac and Cry2Ab toxins), VICOT <Registered Trademark> (cotton varieties expressing VIP toxin), NewLeaf <Registered Trademark> (potato varieties expressing Cry3A toxin), NatureGard <Registered Trademark>, Agrisure <Registered Trademark> GT Advantage (GA21 glyphosate resistance trait), Agrisure <Registered Trademark> CB Advantage (Bt11 corn borer (CB) trait), Protecta <Registered Trademark>, etc.

[0089] The useful plants also include plants that have been endowed with the ability to produce selectively active antipathogenic substances using gene recombination technology.

[0090] Examples of antiviral substances include PR proteins (PRPs, described in EP0392225A); ion channel inhibitors such as sodium channel inhibitors and calcium channel inhibitors (KP1, KP4, KP6 toxins produced by viruses); stilbene synthase; bibenzyl synthase; chitinase; glucanase; peptide antibiotics; heterocyclic antibiotics; and protein factors related to plant disease resistance (referred to as plant disease resistance genes, described in WO03 / 000906), as well as substances produced by microorganisms. Such antiviral substances and recombinant plants that produce them are recorded in EP0392225A, WO95 / 033818, EP0353191A, etc.

[0091] The useful plants also include crops that have been endowed with useful traits such as improved oil content and enhanced amino acid content through genetic recombination technology. Examples include VISTIVE (a registered trademark) (low-linolenic acid soybean with reduced linolenic acid content) or high-lysine (high-oil) corn (corn with increased lysine or oil content).

[0092] Among the useful plants mentioned, there are also crops whose yields have been maintained or increased by using gene recombination technology to confer useful traits such as drought resistance. Examples include DroughtGard (a registered trademark) corn conferred with drought resistance.

[0093] The weed control method of the present invention also shows control efficacy against the aforementioned exemplary weeds that have developed resistance to existing herbicides. Furthermore, the weed control method of the present invention can also be used on plants that have acquired characteristics such as insect resistance, disease resistance, and herbicide resistance through gene recombination, artificial mating, etc.

[0094] In this invention, plants endowed with resistance through breeding methods or gene recombination technology include not only those endowed with resistance through classic varietal hybridization and those endowed with resistance through gene recombination technology, but also those endowed with resistance through new plant breeding techniques (NBTs) that combine molecular biology methods with existing hybridization techniques. New breeding techniques (NBTs) are a general term for varietal improvement (breeding) techniques that combine molecular biology methods. New breeding techniques (NBTs) are documented in books such as "Understanding New Plant Breeding Techniques" (2013, International Literature Company: Ryo Osawa and Hiroshi Emen), and commentary articles such as "Genome Editing Tools in Plants" ("Genes" Vol. 8: p. 399 (2017, Tapan Kumar Mohanta, Tufail Bashir, Abeer Hashem, Elsayed Fathi Abd_Allahand Hanhong Bae)). Examples of such new breeding techniques include genome breeding technology and genome editing technology. Genomic breeding technology refers to techniques used to improve breeding efficiency by utilizing genomic information. It includes DNA marker (also known as genomic marker or gene marker) breeding techniques and genomic selection. For example, DNA marker breeding is a method of selecting offspring with the target useful trait gene from multiple hybrids by using DNA markers—DNA sequences that act as markers of the location of a gene for a specific useful trait on the genome. Analyzing hybrid offspring using DNA markers at the young plant stage has the advantage of effectively reducing the time required for breeding.

[0095] Furthermore, genomic selection, a method that predicts traits based on pre-existing phenotypic and genomic information without phenotypic evaluation, is a technology that can contribute to the efficiency of breeding. Examples of novel breeding technologies (NBTs) include cisgenesis / intragenesis, oligonucleotide directed mutation introduction, RNA-dependent DNA methylation, genome editing, grafting onto GM rootstocks or scions, reverse breeding, Agrobacterium infiltration, and seed production technology (SPT). Tools for genome editing include, for example, zinc-finger nucleases (ZFNs), TALEN, CRISPR / Cas9, CRISPER / Cpf1, and meganucleases, which can perform sequence-specific cleavage. In addition, there are sequence-specific genome modification technologies such as CAS9 endonucleases and Target-AID, which are prepared by modifying these tools.

[0096] Furthermore, the useful traits mentioned above, such as classic herbicide traits or herbicide resistance genes, insecticidal pest resistance genes, pathogen resistance gene production genes, oilseed composition improvements, amino acid content enhancement traits, and drying resistance traits, also include stacked varieties that combine multiple of these traits.

[0100] 50 parts by weight of columnar crystals of sulfonylpyrazol obtained by the method described in Example 3-1 of Patent Document 2, 8 parts by weight of polycarboxylate, 5 parts by weight of polyoxyethylene styrene phenyl ether sulfate, and 1 part by weight of alkylbenzene sulfonate were added, and clay was added as the remainder to make a total of 100 parts by weight. The mixture was then pulverized using an impact mill to obtain a wettable powder.

[0101] [Formulation Example 2]

[0102] Add 50 parts by weight of needle-like crystals of sulfonylpyrazine, 8 parts by weight of polycarboxylate, 5 parts by weight of polyoxyethylene styrene phenyl ether sulfate, and 1 part by weight of alkylbenzene sulfonate. Add clay as the remainder to make a total of 100 parts by weight. Mix and pulverize using an impact mill to obtain a wettable powder.

[0103] [Example 1]

[0104] In a greenhouse with an average temperature of 25°C (maximum 30°C, minimum 25°C), sandy loam soil (70.3% sand, 17.3% silt, 12.4% clay) was filled into 11cm x 11cm x 11cm x 11cm depth plastic pots. Fifteen Echinochloa crus-galli seeds and twenty Amaranthus retoflexus seeds were sown, and the pots were covered with the same soil to a thickness of 1cm. Then, the wettable powder of Formulation Example 1 was measured to achieve a sulfonylpyrazole dosage of 22.5g per hectare, diluted with water, and evenly distributed on the soil surface using a small sprayer at a rate of 200 liters per hectare. Artificial rainfall of 10mm was provided on the day of treatment, the following day, and two days later, accumulating to a total of 30mm. Then, barnyard grass and reverse-branch amaranth were cultivated, and their growth was investigated 15, 20, and 29 days after treatment. The degree of growth inhibition was determined by the percentage of the untreated area. The same experiment was conducted three times, and the average value of each time was used as the representative value.

[0105] [Comparative Example 1]

[0106] Except that the wettable powder of Formulation Example 2 was used instead of the wettable powder of Formulation Example 1, the same procedure as in Example 1 was followed to investigate the growth of barnyard grass and reverse-branch amaranth.

[0107] The results of the examples and comparative examples are shown in Tables 1 and 2.
