[0171] The present invention further provides a method for controlling weeds at a site, the method comprising applying to the site a composition comprising a compound having formula (I) to control the amount of weeds. Furthermore, the present invention can further provide a method for selectively controlling weeds at a site comprising useful (crop) plants and weeds, wherein the method comprises applying to the site a composition according to the present invention to control the amount of weeds. 'Control' means killing, reducing, or delaying growth or preventing or reducing germination. It should be noted that the compounds of the present invention exhibit significantly improved selectivity compared to known structurally similar compounds. Typically, the plant to be controlled is an unwanted plant (weed). 'Site' means an area in which the plant is growing or will grow. Application can be made to the site before and / or after the emergence of the crop plants. Some crop plants can inherently tolerate the herbicidal effects of compounds having formula (I).
[0172] The application rate of compounds having formula (I) can vary within a wide range and depends on soil properties, application method (pre- or post-emergence; seed dressing; application in seed furrows; no-till application, etc.), crop species, one or more weeds to be controlled, prevailing climatic conditions, and other factors governed by the application method, application time, and target crop. Compounds having formula I according to the invention are typically applied at rates from 10 g / ha to 2500 g / ha, particularly from 25 g / ha to 1000 g / ha, and even more particularly from 25 g / ha to 250 g / ha.
[0173] The composition is usually applied by spraying, typically using a tractor-mounted sprayer for large areas, but other methods such as dusting (for powders), dripping, or immersion can also be used.
[0174] The term "useful plants" should be understood to also include useful plants that have developed tolerance to herbicides (like bromuconazole) or herbicide classes (e.g., 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, ALS inhibitors such as flusulfuron, fluprosulfuron, and triflusulfone, (5-enol-pyruvyl-shikimate-3-phosphate-synthetase) (EPSPS) inhibitors, glutamine synthase (GS) inhibitors, or protoporphyrinogen oxidase (PPO) inhibitors) through conventional breeding methods or genetic engineering. Examples of crops that have been induced to tolerate imidazolinones (e.g., methoxyfenozide) through conventional breeding methods (mutation) are... Summer rapeseed (Carnora). Examples of crops that have been genetically engineered to be resistant to herbicides or herbicides include glyphosate and glufosinate-resistant maize varieties, which are roundup... Herculex and Liberty Trademark names are available for purchase.
[0175] The term "useful plant" should be understood to also include useful plants that have been transformed by the use of recombinant DNA technology to enable them to synthesize one or more selectively acting toxins, such as those known to come from toxin-producing bacteria, especially those of the genus Bacillus.
[0176] Examples of such plants are: (Corn variety expressing CryIA(b) toxin); YieldGard (A maize variety expressing CryIIIB(b1) toxin); YieldGard (Maize variety expressing CryIA(b) and CryIIIB(b1) toxins); (A maize variety expressing the Cry9(c) toxin); Herculex (A maize variety that expresses the CryIF(a2) toxin and the enzyme phosphatidylcholine N-acetyltransferase (PAT) to acquire tolerance to the herbicide glufosinate-ammonium); NuCOTN (Cotton variety expressing CryIA(c) toxin); Bolgard (Cotton variety expressing CryIA(c) toxin); Bolgard (Cotton varieties expressing CryIA(c) and CryIIA(b) toxins); (Cotton variety, expressing VIP toxin); (Potato variety that expresses CryIIIA toxin); GT Advantage (GA21 glyphosate resistance) CBAdvantage (Bt11 corn borer (CB) traits), RW (corn rootworm trait) and
[0177] Plant crops or their seed material can be both herbicide-resistant and insect-resistant (“cumulative” transgenic events). For example, seeds can express the insecticidal Cry3 protein while simultaneously being resistant to glyphosate.
[0178] Crop plants should also be understood to include those obtained through conventional breeding or genetic engineering methods and that contain so-called exported traits (such as improved storage stability, higher nutritional value, and improved flavor).
[0179] Unwanted plants (collectively referred to as 'weeds') can be controlled using compounds having formula (I) (or compositions containing it). Weeds to be controlled can be monocotyledonous species, such as *Agrostis*, *Alopecurus*, *Avena*, *Brachiaria*, *Bromus*, *Cenchrus*, *Cyperus*, *Digitaria*, *Echinochloa*, *Eleusine*, *Lolium*, *Monochoria*, *Rottboellia*, *Sagittaria*, *Scirpus*, and *Setaria*. ) and the genus Sorghum, which can also be dicotyledonous species, such as Abutilon, Amaranthus, Ambrosia, Chenopodium, Chrysanthemum, Conyza, Galium, Ipomoea, Nasturtium, Sida, Sinapis, Solanum, Stellaria, Veronica, Viola, and Xanthium.
[0180] Compounds having formula (I) can be used in their unmodified form, or preferably with adjuvants conventionally used in the formulation field to provide a herbicidal composition, using formulation adjuvants such as carriers, solvents, and surfactants (SAAs). Therefore, the present invention further provides a herbicidal composition comprising at least one compound having formula (I) and an agriculturally acceptable carrier and optionally an adjuvant. An agriculturally acceptable carrier is, for example, a carrier suitable for agricultural use. Agricultural carriers are well known in the art.
[0181] These herbicidal compositions generally contain from 0.1% to 99%, particularly from 0.1% to 95% by weight, of a compound having Formula I, and from 1% to 99.9% by weight of a formulation adjuvant, which preferably includes from 0% to 25% by weight of a surfactant.
[0182] The composition can be selected from many formulation types. These include emulsion concentrates (EC), suspension concentrates (SC), suspension emulsions (SE), capsule suspensions (CS), water-dispersible granules (WG), emulsifiable granules (EG), water-in-oil emulsions (EO), oil-in-water emulsions (EW), microemulsions (ME), oil dispersants (OD), oil suspensions (OF), oil-soluble liquids (OL), soluble concentrates (SL), ultra-low volume suspensions (SU), ultra-low volume liquids (UL), parent drug (TK), dispersible concentrates (DC), soluble powders (SP), wettable powders (WP), and soluble granules (SG). In any case, the type of formulation chosen will depend on the specific intended purpose and the physical, chemical, and biological properties of the compound having formula (I).
[0183] Soluble powders (SPs) can be prepared by mixing a compound having formula (I) with one or more water-soluble inorganic salts (such as sodium bicarbonate, sodium carbonate, or magnesium sulfate) or one or more water-soluble organic solids (such as polysaccharides) and optionally one or more wetting agents, one or more dispersants, or a mixture of said reagents to improve water dispersibility / water solubility. The mixture is then ground into a fine powder. Similar compositions can also be granulated to form water-soluble granules (SGs).
[0184] Wettable powders (WPs) can be prepared by mixing a compound having formula (I) with one or more solid diluents or carriers, one or more wetting agents, and preferably one or more dispersants, and optionally one or more suspending agents to promote dispersion in a liquid. The mixture is then ground into a fine powder. Similar compositions can also be granulated to form water-dispersible granules (WGs).
[0185] Granules (GR) can be formed by granulating a mixture of a compound having formula (I) with one or more powdered solid diluents or carriers, or by absorbing a compound having formula (I) (or a solution thereof in a suitable reagent) into a porous particulate material (such as pumice, attapulgite clay, bleaching clay, kieselguhr, diatomaceous earths, or corn cob powder), or by adsorbing a compound having formula (I) (or a solution thereof in a suitable reagent) onto a hard core material (such as sand, silicates, mineral carbonates, sulfates, or phosphates) and, if necessary, drying it to form pre-formed blank granules. Reagents commonly used to aid absorption or adsorption include solvents (such as aliphatic and aromatic petroleum solvents, alcohols, ethers, ketones, and esters) and binders (such as polyvinyl acetate, polyvinyl alcohol, dextrin, sugars, and vegetable oils). One or more other additives (e.g., emulsifiers, wetting agents, or dispersants) may also be included in the granules.
[0186] Dispersible concentrates (DCs) can be prepared by dissolving a compound having formula (I) in water or an organic solvent (such as a ketone, alcohol, or glycol ether). These solutions may contain surfactants (e.g., to improve water dilution or to prevent crystallization in spray cans).
[0187] Emulsifiable concentrates (ECs) or oil-in-water emulsions (EWs) can be prepared by dissolving a compound having formula (I) in an organic solvent (optionally containing one or more wetting agents, one or more emulsifiers, or a mixture of said reagents). Suitable organic solvents used in ECs include aromatic hydrocarbons (such as alkylbenzenes or alkylnaphthalenes, exemplified by SOLVESSO 100, SOLVESSO 150, and SOLVESSO 200; SOLVESSO is a registered trademark), ketones (such as cyclohexanone or methylcyclohexanone), and alcohols (such as benzyl alcohol, furfuryl alcohol, or butanol), N-alkylpyrrolidones (such as N-methylpyrrolidone or N-octylpyrrolidone), and dimethylamides of fatty acids (such as C8-C...). 10 (Fatty acid dimethylamide) and chlorinated hydrocarbons. EC products can spontaneously emulsify when added to water, producing an emulsion with sufficient stability to allow for spray application using appropriate equipment.
[0188] The preparation of an emulsion (EW) involves obtaining a compound of formula (I) as a liquid (or, if not a liquid at room temperature, which can be melted at a reasonable temperature typically below 70°C) or as a solution (by dissolving it in a suitable solvent), and then emulsifying the resulting liquid or solution under high shear into water containing one or more SAAs to produce an emulsion. Suitable solvents used in EWs include vegetable oils, chlorinated hydrocarbons (such as chlorobenzene), aromatic solvents (such as alkylbenzenes or alkylnaphthalenes), and other suitable organic solvents with low solubility in water.
[0189] Microemulsions (MEs) can be prepared by mixing water with a blend of one or more solvents and one or more SAAs to spontaneously produce a thermodynamically stable, isotropic liquid formulation. The compound having formula (I) is initially present in water or in the solvent / SAA blend. Suitable solvents used in MEs include those described above used in ECs or EWs. MEs can be oil-in-water or water-in-oil systems (whichever system is present can be determined by conductivity measurements) and can be used to mix water-soluble and oil-soluble biocides in the same formulation. MEs are suitable for dilution in water, maintaining as a microemulsion or forming a conventional oil-in-water emulsion.
[0190] Suspension concentrates (SCs) can comprise aqueous or non-aqueous suspensions of finely dispersed insoluble solid particles of a compound having formula (I). SCs can be prepared by ball milling or bead milling of a solid compound having formula (I) with one or more dispersants in a suitable medium to produce a fine-particle suspension of the compound. One or more wetting agents may be included in the composition, and a suspending agent may be included to reduce the rate of particle settling. Alternatively, a compound having formula (I) can be dry-milled and added to water containing the reagents described above to produce the desired final product.
[0191] Aerosol formulations comprise compounds having formula (I) and suitable propellants (e.g., n-butane). Compounds having formula (I) can also be dissolved or dispersed in a suitable medium (e.g., water or a water-miscible liquid, such as n-propanol) to provide compositions for use in unpressurized, manually operated spray pumps.
[0192] Capsule suspensions (CS) can be prepared in a manner similar to that used in the preparation of EW formulations, but with an additional polymerization stage, resulting in an aqueous dispersion of oil droplets, each droplet encapsulated in a polymer shell and containing a compound of formula (I) and optionally a carrier or diluent for that droplet. The polymer shell can be produced via interfacial polycondensation or via a coagulation process. These compositions can provide controlled release of compounds of formula (I) and can be used for seed treatment. Compounds of formula (I) can also be formulated in a biodegradable polymer matrix to provide slow, controlled release of the compound.
[0193] The composition may contain one or more additives to improve the biocompatibility of the composition, for example by improving wettability, retention, or distribution on a surface; rain resistance on the treated surface; or absorption or flow of compounds having formula (I). Such additives include surfactants (SAAs), oil-based spray additives such as certain mineral oils or natural vegetable oils (such as soybean and rapeseed oils), modified vegetable oils (such as methylated rapeseed oil (MRSO)), and blends of these with other bioenhancing adjuvants (components that can help or modify the effects of compounds having formula (I)).
[0194] The wetting agent, dispersant, and emulsifier can be cationic, anionic, amphoteric, or nonionic SAA.
[0195] Suitable cationic types of SAAs include quaternary ammonium compounds (e.g., cetyltrimethylammonium bromide), imidazolines, and amine salts.
[0196] Suitable anionic SAAs include alkali metal salts of fatty acids, salts of aliphatic monoesters of sulfuric acid (e.g., sodium lauryl sulfate), salts of sulfonated aromatic compounds (e.g., sodium dodecylbenzenesulfonate, calcium dodecylbenzenesulfonate, butyl naphthalene sulfonate, and mixtures of sodium di-isopropyl-naphthalene sulfonate and sodium tri-isopropyl-naphthalene sulfonate), ether sulfates, alcohol ether sulfates (e.g., sodium laureth-3-sulfate), ether carboxylates (e.g., sodium laureth-3-carboxylate), phosphate esters (products of the reaction between one or more fatty alcohols and phosphoric acid (mainly monoesters) or phosphorus pentoxide (mainly diesters), such as the reaction between lauryl alcohol and tetraphosphate; these products may also be ethoxylated), sulfosuccinates, paraffin or olefin sulfonates, taurines, lignosulfonates, and phosphate / sulfate salts of tristyrylphenols.
[0197] Suitable amphoteric types of SAAs include betaine, propionate, and glycine salt.
[0198] Suitable non-ionic types of SAAs include condensation products of alkyl oxidases (such as ethylene oxide, propylene oxide, butane oxide, or mixtures thereof) with fatty alcohols (such as oleyl alcohol or cetyl alcohol) or with alkylphenols (such as octylphenol, nonylphenol, or octylcresol); partial esters derived from long-chain fatty acids or hexyl anhydrides; condensation products of said partial esters with ethylene oxide; block polymers (comprising ethylene oxide and propylene oxide); alkanolamides; monoesters (e.g., fatty acid polyethylene glycol esters); amine oxides (e.g., lauryl dimethylamine oxide); lecithin and sorbitol and their esters, alkyl polyglycosides, and tristyrylphenols.
[0199] Suitable suspending agents include hydrophilic colloids (such as polysaccharides, polyvinylpyrrolidone, or sodium carboxymethyl cellulose) and expansive clays (such as bentonite or attapulgite).

[0202] Safeguards of compounds having formula (I) may also be in the form of esters or salts, as mentioned, for example, in The Pesticide Manual, 16th edition (BCPC), 2012. References to antitoxin quinine also apply to its lithium, sodium, potassium, calcium, magnesium, aluminum, iron, ammonium, quaternary ammonium, sulfonium, or phosphonium salts (as disclosed in WO 02 / 34048).
[0203] Preferably, the mixing ratio of the compound having formula (I) to the safener is from 100:1 to 1:10, especially from 20:1 to 1:1.
[0204] Compounds having formula (I) are typically used in the form of agricultural chemical compositions and can be applied simultaneously or sequentially to crop areas or plants to be treated, along with other compounds. These other compounds may, for example, be fertilizers or micronutrient donors or other formulations that influence plant growth. They may also be selective or non-selective herbicides, together with insecticides, fungicides, bactericides, nematicides, molluscicides, or mixtures thereof, and, if desired, with additional carriers, surfactants, or application-promoting adjuvants commonly used in the formulation field.
[0205] As used herein, the term "site" means the place in which or on which a plant grows, or the place where the seeds of a cultivated plant are sown, or the place where the seeds will be placed in the soil. It includes soil, seeds, and seedlings, along with the established vegetation.
[0206] The term "plant" refers to all the tangible parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, culms, leaves, and fruits.
[0207] The term "plant propagation material" should be understood to refer to the reproductive parts of a plant, such as seeds, which can be used for plant propagation, as well as nutrient materials, such as cuttings or tubers (e.g., potatoes). References may include, for example, seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes, and parts of the plant. References may also include germinating plants and young plants that will be transplanted after germination or emergence. These young plants may be protected before transplanting by complete or partial treatment with maceration. Preferably, "plant propagation material" should be understood to refer to seeds.
[0208] The pesticides mentioned in this article that use their common names are, for example, known from "The Pesticide Manual", 15th edition, British Crop Protection Council 2009.
[0209] Compounds having formula (I) can be used in their unmodified form, or preferably, in conjunction with adjuvants conventionally used in the field of formulations. For this purpose, they can be conveniently formulated in known manner as emulsifiable concentrates, coating pastes, directly sprayable or dilutable solutions or suspensions, diluted emulsions, wettable powders, soluble powders, dusts, granules, and encapsulants, for example, in polymeric substances. The method of application, such as spraying, atomizing, dusting, spreading, smearing, or watering, is selected according to the intended purpose and the prevailing environment for the type of composition. The composition may also contain additional adjuvants, such as stabilizers, defoamers, viscosity modifiers, binders, or thickeners, along with fertilizers, micronutrient donors, or other formulations used to achieve specific effects.
[0210] Suitable carriers and adjuvants, for example, for agricultural use, can be solid or liquid and are substances useful in formulation techniques, such as natural or recycled minerals, solvents, dispersions, wetting agents, thickeners, binders, or fertilizers. Such carriers are described, for example, in WO 97 / 33890.
[0211] Compounds having formula (I) are typically used in the form of a composition and can be applied simultaneously or sequentially with other compounds to crop areas or plants to be treated. These other compounds may, for example, be fertilizers or micronutrient donors or other formulations that influence plant growth. They may also be selective or non-selective herbicides, together with insecticides, fungicides, bactericides, nematicides, molluscicides, or mixtures of several of these formulations, and, if desired, with other carriers, surfactants, or application-promoting adjuvants commonly used in the formulation field.
[0212] A compound having formula (I) may be the sole active ingredient in a composition, or, where appropriate, it may be mixed with one or more other active ingredients (such as pest control agents, fungicides, synergists, herbicides, or plant growth regulators). In some cases, the additional active ingredients may result in unexpected synergistic activities.
[0213] Typically, formulations comprise from 0.01% to 90% by weight of the active ingredient, from 0% to 20% of an agriculturally acceptable surfactant, and from 10% to 99.99% of a solid or liquid formulation inert agent and one or more adjuvants, the active agent being a compound having at least formula (I) together with components (B) and (C), and optionally other active agents (particularly microbicides, preservatives, or the like). Concentrated forms of the composition typically contain between about 2% and 80% by weight, preferably between about 5% and 70% by weight of the active agent. Application forms of the formulation may, for example, contain from 0.01% to 20% by weight, preferably from 0.01% to 5% by weight of the active agent. However, commercially available products will preferably be formulated as concentrates, and end users will typically use diluted formulations.

After 8 days of cultivation under controlled conditions in a greenhouse (24°C / 16°C, day / night; 14-hour light; 65% humidity), the plants were sprayed with an aqueous solution derived from an industrial-grade formulation of the active ingredient in an acetone / water (50:50) solution containing 0.5% Tween 20 (polyoxyethylene sorbitan monolaurate, CAS RN 9005-64-5). Unless otherwise specified, the compound was applied at 1000 g / ha. The test plants were then grown in a greenhouse under controlled conditions (24°C / 16°C, day / night; 14-hour light; 65% humidity) and watered twice daily. The percentage of damage to the plants was evaluated after 13 days. The table below shows biological activity on a five-point scale (5 = 81%-100%; 4 = 61%-80%; 3 = 41%-60%; 2 = 21%-40%; 1 = 10%-20%; 0 = 0%; - = not tested).
