[0016] Detailed description of the invention As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “have,” “have,” “contain,” “contain,” “characterized by,” or any variation thereof are intended to refer to comprehensive inclusion under any expressly indicated limitation. For example, a process or method that includes a list of elements may include other elements that are not expressly listed or that are specific to such a process or method, but are not necessarily limited to those elements.

[0017] The transitional phrase “consisting of” excludes any unspecified element, process, or component. In the case of claims, the phrase would close the claim to the inclusion of substances other than those described, except for impurities that are usually present. If the phrase “consisting of” appears in a section of the claim rather than immediately following the preface, it limits only the elements described in that section; other elements are not excluded from the claim as a whole.

[0018] The transitional phrase “essentially from” is used to define a process or method that includes materials, processes, features, components, or elements in addition to those literally disclosed, provided that these additional materials, processes, features, components, or elements do not substantially affect the fundamental and novel features of the disclosure. The term “essentially from” lies between “including” and “consisting of.”

[0019] If the applicants define the disclosure or any part thereof using a non-restrictive term such as “including,” that term shall, naturally, be interpreted (unless otherwise stated) as also describing disclosures that use the terms “essentially consisting of” or “consisting of.”

[0020] Furthermore, unless explicitly stated otherwise, "or" refers to a compatible or not an exclusive or. For example, condition A or or B is satisfied by one of the following: A is true (or exists) and B is false (or does not exist), A is false (or does not exist) and B is true (or exists), and both A and B are true (or exist).

[0021] Furthermore, the indefinite articles “a” and “an” preceding any element or component of this disclosure are intended to be non-restrictive with respect to the number of instances (i.e., existences) of that element or component. Thus, “a” or “an” is to be read as including one or at least one, and the singular form of an element or component also includes plurals unless it is explicitly stated that the number is singular.

[0022] As used herein, the term "C1-C6 alkyl" includes linear or branched alkyl groups having 1 to 6 carbon atoms, e.g., methyl, ethyl, n-propyl, i-propyl, or various butyl, pentyl, or hexyl isomers. Similarly, the term "C1-C4 alkyl" includes linear or branched alkyl groups having 1 to 4 carbon atoms, e.g., methyl, ethyl, n-propyl, i-propyl, or various butyl isomers, and the term "C1-C3 alkyl" includes methyl, ethyl, n-propyl, and i-propyl.

[0023] As used herein, the term “halogen” includes fluorine, chlorine, bromine, or iodine. Where G is “SO2(4-Me-Ph)”, this is instead defined as “SO2(p-tolyl)”. The term “reacting” and similar terms refer to adding, contacting, or mixing two or more reagents under appropriate conditions to produce the indicated and / or desired product. Naturally, the reaction producing the indicated and / or desired product does not necessarily have to occur directly from the combination of the two reagents initially added; i.e., one or more intermediates may be present in the mixture that ultimately lead to the formation of the indicated and / or desired product. The reaction may occur in or without a solvent, at temperatures above or below room temperature, under an inert atmosphere, etc.

[0024] As used herein, the term “methoxylating agent” refers to a chemical reagent used to add a methoxy group, i.e., OCH3, to a compound. Examples of non-limiting methoxylating agents include sodium methoxide or potassium methoxide. As used herein, the term “tmp-zinc base” refers to a chemical complex containing zinc and 2,2,6,6-tetramethylpiperidine. Examples of non-limiting zinc bases include (tmp)2Zn·2·MgCl2·2·LiCl, (tmp)2Zn·2·LiCl, and (tmp)2Zn.

[0025] As used herein, the term “halogenating agent” refers to a chemical reagent used to add a halogen atom, such as Cl, Br, or I, to a compound. Examples of non-limiting halogenating agents include iodine, 1,3-dichloro-5,5-dimethylhydantoin, 1,3-dibromo-5,5-dimethylhydantoin, 1,3-diiodo-5,5-dimethylhydantoin, trichloroisocyanuric acid, sulfuryl chloride, N-bromosuccinimide, and N-chlorosuccinimide.

[0026] Compounds of formula I typically exist in more than one solid form. Therefore, compounds of formula I encompass all crystalline and amorphous forms of the compounds they represent. Amorphous forms include embodiments that are solids, such as waxes and rubbers, as well as embodiments that are liquids, such as solutions and dissolves. Crystalline forms include embodiments that represent essentially a single crystalline form and embodiments that represent a mixture of polymorphs (i.e., different crystalline forms). The term “polymorph” refers to a particular crystalline form of a chemical compound that can crystallize in different crystalline forms, these forms having different arrangements and / or conformations of molecules in the crystal lattice. Polymorphs may have the same chemical composition, but they may also differ in composition due to the presence or absence of co-crystallized water or other molecules, which may be weakly or strongly bonded in the lattice. Polymorphs may differ in chemical, physical, and biological properties such as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspension, dissolution rate, and bioavailability.

[0027] As is obvious to those skilled in the art, polymorphs of compounds of formula I may exhibit beneficial effects (e.g., suitability for the manufacture of useful formulations, improved biological performance) compared to other polymorphs or mixtures of polymorphs of the same compound of formula I. The manufacture and isolation of specific polymorphs of compounds of formula I can be achieved by methods known to those skilled in the art, such as crystallization using selected solvents and temperatures. For a comprehensive discussion of polymorphisms, see R. Hilfi. See ke (ed.), Polymorphism in the Pharmaceutical Industry, Wiley-VCH, Weinheim, 2006.

[0028] Synthetic methods for producing N-oxides of heterocyclic and tertiary amines are well known to those skilled in the art. Examples of procedures for producing N-oxides include the oxidation of heterocyclic and tertiary amines using peroxy acids, such as peracetic acid and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides, such as t-butyl hydroperoxide, sodium perborate, and dioxiranes, such as dimethyldioxirane. These methods for producing N-oxides have been widely described and reviewed in the literature, e.g.: TLGilchrist in Comprehensive Organic Synthesis, Vol. 7, pp. 748-750, edited by SVLey, Pergamon See also: Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, Vol. 3, pp. 18-20, edited by AJBoulton and A. McKillop, Pergamon Press; MRGrimmett and BRTKeene in Advances in Heterocyclic Chemistry, Vol. 43, pp. 149-161, edited by ARKatritzky, Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemistry, Vol. 9, pp. 285-291, edited by ARKatritzky and AJBoulton, Academic Press; and GWHCheeseman and ESGWerstiuk in Advances in Heterocyclic Chemistry, Vol. 22, pp. 390-392, edited by ARKatritzky and AJBoulton, Academic Press. Therefore, as is obvious to those skilled in the art, not all nitrogen-containing heterocycles can form N-oxides, since nitrogen requires a lone pair of electrons to be available for oxidation to an oxide; those skilled in the art will know which nitrogen-containing heterocycles can form N-oxides.

[0029] Those skilled in the art will understand that salts of chemical compounds, under environmental and physiological conditions, are in equilibrium with their corresponding unsalted forms, and therefore salts share the biological utility of their unsalted forms. Accordingly, a wide variety of salts of compounds of formula I are useful (i.e., agrochemically suitable) for controlling undesirable vegetation. Examples of salts of compounds of formula I include acid addition salts with inorganic or organic acids such as hydrobromic acid, hydrochloric acid, nitric acid, phosphoric acid, sulfuric acid, acetic acid, butyric acid, fumaric acid, lactic acid, maleic acid, malonic acid, oxalic acid, propionic acid, salicylic acid, tartaric acid, 4-toluenesulfonic acid, or valeric acid. Therefore, this disclosure includes compounds selected from formula I, its N-oxides, and agrochemically suitable salts.

[0191] "Photosystem II inhibitors" (b1) are Q B - Binds to the D-1 protein in the binding niche, and as a result Q in the chloroplast thylakoid membrane. A From Q B It is a chemical compound that blocks electron transport to photosystem II. Electrons whose passage through photosystem II is blocked are transferred through a series of reactions to form toxic compounds, which disrupt the cell membrane and lead to chloroplast swelling, membrane leakage, and ultimately cell destruction. BThe binding niche has three distinct binding sites: binding site A binds to triazines such as atrazine, triazinones such as hexazinone, and uracils such as bromacil; binding site B binds to phenylureas such as diurone; and binding site C binds to benzothiadiazoles such as bentazone, nitriles such as bromoxynil, and phenylpyridazines such as pyridate. Examples of photosystem II inhibitors include ametrine, amicarbazone, atrazine, bentazone, bromacil, bromophenoxime, bromoxynil, chlorbromulone, chloridazone, chlorotolurone, chloroxurone, cumilone, cyanazine, dimuron, desmedifam, desmethrin, dimeflon, dimethametrin, diurone, ethidimulone, fenulon, fluomethron, hexazinone, ioxynil, and isoproturone.

[0192] "AHAS inhibitors" (b2) are acetolactate synthase (ALS), also known as acetolactate synthase. It is a chemical compound that inhibits tohydroxy acid synthase (AHAS), and therefore kills plants by inhibiting the production of branched-chain aliphatic amino acids such as valine, leucine, and isoleucine, which are necessary for protein synthesis and cell proliferation.Examples of AHAS inhibitors include amidosulfuron, azimsulfuron, bensulfuron-methyl, bispiribac-sodium, chloransulam-methyl, chlorimulon-ethyl, chlorsulfuron, cinosulfuron, cyclosulfamuron, diclosulam, etamethulfuron-methyl, ethoxysulfuron, flurazasulfuron, florasulam, flucarbazone-sodium, flumethoslam, flupyrsulfuron-methyl, and flupyrsulfuron-na Thorium, horamsulfuron, halosulfuron-methyl, imazametabenz-methyl, imazamox, imazapick, imazapyr, imazakine, imazetapir, imazosulfuron, iodosulfuron-methyl (including sodium salt), iofensulfuron (2-iodo-N-[[(4-methoxy-6-methyl-1,3,5-triazine-2-yl)amino]carbonyl]benzenesulfonamide), mesosulfuron-methyl, metazosulfuron (3-Chloro-4-(5,6-dihydro-5-methyl-1,4,2-dioxazin-3-yl)-N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-1-methyl-1H-pyrazole-5-sulfonamide), Methoslam, Methosulfuron-methyl, Nicosulfuron, Oxasulfuron, Penoxuslam, Primisulfuron-methyl, Propoxycarbazone-sodium, Propyrisulfuron Examples include (2-chloro-N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-6-propylimidazo[1,2-b]pyridazine-3-sulfonamide), prosulfuron, pyrazosulfuron-ethyl, pyribenzoxime, pyrifthalide, pyriminovac-methyl, pyrithiovac-sodium, limsulfuron, sulfomethane-methyl, sulfosulfuron, thiencarbazone, thifensulfuron-methyl, triafamone (N-[2-[(4,6-dimethoxy-1,3,5-triazine-2-yl)carbonyl]-6-fluorophenyl]-1,1-difluoro-N-methylmethanesulfonamide), triasulfuron, trivenuron-methyl, trifloxysulfuron (including sodium salt), triflusulfuron-methyl, and tritosulfuron.

[0193] "ACCase inhibitors" (b3) are chemical compounds that inhibit the acetyl-CoA carboxylase enzyme, which catalyzes the initial stages of lipid and fatty acid synthesis in plants. Lipids are essential components of cell membranes, and without them, new cells cannot be produced. Inhibition of acetyl-CoA carboxylase and the subsequent loss of lipid production lead to a loss of cell membrane integrity, particularly in areas of active growth such as meristems. Ultimately, shoot and rhizome growth stops, and shoot meristems and rhizome buds begin to wither. Examples of ACCase inhibitors include alloxidim, butroxidim, cretodym, clodinahop, cycloxidim, cyhalofop, diclohop, phenoxaprop, fluazihop, haloxyhop, pinoxadene, propoxoxidim, propaxifop, quizalohop, cethoxidim, tepraloxidim, and tralcoxidim, which include fragmented forms such as phenoxaprop-P, fluazihop-P, haloxyhop-P, and quizalohop-P, as well as ester forms such as clodinahop-propargyl, cyhalofop-butyl, diclohop-methyl, and phenoxaprop-P-ethyl.

[0194] Auxin is a plant hormone that regulates growth in many plant tissues. "Auxin mimics" (b4) are chemical compounds that mimic the plant growth hormone auxin and therefore cause uncontrolled and disordered growth that leads to plant death in susceptible species. Examples of auxin mimics include aminocyclopyrachlor (6-amino-5-chloro-2-cyclopropyl-4-pyrimidinecarboxylic acid) and its methyl and ethyl esters, as well as its sodium and potassium salts, aminopyralide, benazoline-ethyl, chloramben, crasiphos, clomeprop, clopyralide, dicamba, 2,4-D, 2,4-DB, dichlorprop, fluroxypyr, and harauxifen (4-amino-3-c Examples include lol-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylate), harauxifen-methyl (4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylate methyl), MCPA, MCPB, mecoprop, picrolam, quinchlorac, kinmelac, 2,3,6-TBA, triclopyr, and 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-5-fluoro-2-pyridinecarboxylate methyl.

[0195] "EPSP synthase inhibitors" (b5) are chemical compounds that inhibit 5-enoylpyruvicishikimic acid-3-phosphate synthase, an enzyme involved in the synthesis of aromatic amino acids such as tyrosine, tryptophan, and phenylalanine. EPSP inhibitor herbicides are readily absorbed through plant leaves and travel through the phloem to the growing point. Glyphosate is a relatively non-selective post-emergence herbicide belonging to this group. Glyphosate includes esters and salts such as ammonium, isopropylammonium, potassium, sodium (including sesquisodium), and trimethium (or referred to as sulfosate).

[0196] "Photosystem I electron diverters" (b6) are chemical compounds that accept electrons from Photosystem I and, after several cycles, generate hydroxyl radicals. These radicals are highly reactive and readily destroy unsaturated lipids, including membrane fatty acids and chlorophyll. This disrupts cell membrane integrity, resulting in the "leakage" of cells and organelles, rapid wilting and drying of leaves, and ultimately plant death. Examples of this second type of photosynthesis inhibitor include diquat and paraquat.

[0197] "PPO inhibitors" (b7) are chemical compounds that inhibit the enzyme protoporphyrinogen oxidase, which rapidly leads to the formation of highly reactive compounds in plants that rupture cell membranes and cause leakage of cell sap. Examples of PPO inhibitors include asifluorphen-sodium, azaphenidine, benzfenzizone, bifenox, butafenacil, carfentrazone, carfentrazone-ethyl, clomethoxyfen, synidone-ethyl, fluazolate, flufenpyr-ethyl, flumimicrolac-pentyl, flumioxazine, fluoroglycofen-ethyl, fluthiaset-methyl, homesafen, halosaphen, lactofen, oxaziargyl, oxadiazone, oxyflofen, pentoxazone, profluazole, pyraclonil, pyraflufen-ethyl, saflufenacil, sulfentrazone, tidiadimine, and trifludimoxazine Examples include (dihydro-1,5-dimethyl-6-thioxo-3-[2,2,7-trifluoro-3,4-dihydro-3-oxo-4-(2-propyne-1-yl)-2H-1,4-benzoxazine-6-yl]-1,3,5-triazine-2,4(1H,3H)-dione) and thiafenacil (methyl N-[2-[[2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-4-fluorophenyl]thio]-1-oxopropyl]-β-alaninate).

[0198] "GS inhibitors" (b8) are chemical compounds that inhibit the activity of glutamine synthase, which plants use to convert ammonia into glutamine. As a result, ammonia accumulates and glutamine levels decrease. Plant damage is likely due to a combination of ammonia toxicity and a deficiency of amino acids required for other metabolic processes. Examples of GS inhibitors include glufosinate and glufosinate-ammonium and other phosphinothricin derivatives, as well as its esters and salts such as glufosinate-P ((2S)-2-amino-4-(hydroxymethylphosphinyl)butanoic acid) and bilanaphos.

[0199] "VLCFA elongase inhibitors" (b9) are herbicides with a wide variety of chemical structures that inhibit elongase. Elongase is involved in the biosynthesis of VLCFAs in chloroplasts. Alternatively, it is one of the enzymes located near chloroplasts. In plants, very long-chain fatty acids are the main components of hydrophobic polymers that prevent drying on the leaf surface and provide stability to pollen grains. Examples of such herbicides include acetochlor, alachlor, anirophos, butachlor, cafenstrole, dimetachlor, dimethenamide, diphenamide, and phenoxasulfone. Examples include (3-[[(2,5-dichloro-4-ethoxyphenyl)methyl]sulfonyl]-4,5-dihydro-5,5-dimethylisoxazole), fentrazamide, flufenacet, indanophan, mefenacet, metazachlor, metrachlor, naproanilide, napropamide, napropamide-M ((2R)-N,N-diethyl-2-(1-naphthalenyloxy)propanamide), petoxamide, piperofos, pretilachlor, propachlor, propisochlor, pyroxasulfone, and tenylchlor, which include divided forms such as S-metrachlor and chloroacetamide and oxyacetamide.

Two to three iodine crystals were added to activate the magnesium. A solution of 1-bromo-2-methylnaphthalene (31.0 mL, 0.20 mol) in tetrahydrofuran (200 mL) was added dropwise to the magnesium. After adding 25 mL of the solution, the addition was stopped and the mixture was allowed to gradually generate heat. When a small amount of bubbles were observed, the addition was continued at a rate that maintained a controlled, active reaction. Towards the end of the addition, the reaction mixture was externally heated to maintain a gentle reflux. The reaction mixture was heated for 1 hour after the addition was complete.

[0256] Compounds of formula I are generally used in compositions, i.e., formulations, as herbicidal active ingredients, together with at least one further component selected from the group consisting of surfactants, solid diluents, and liquid diluents. In certain embodiments, the further component may act as a carrier. The components of the formulation or composition are selected to be in harmony with the physical properties of the active ingredient, the method of application, and environmental factors such as soil type, humidity, and temperature.

[0257] Useful formulations include both liquid and solid compositions containing the compound of formula I. Examples of liquid compositions include liquid formulations (including emulsions), suspensions, and emulsions (including microemulsions, oil-in-water emulsions, flowable formulations, and / or suspend emulsions). These can be made into gels by increasing their viscosity in some cases. Common types of aqueous liquid compositions include liquids, SC agents (suspension concentrates), CS agents (capsule suspensions), concentrated emulsions, microemulsions, oil-in-water emulsions, flowables, and suspension emulsions. Common types of non-aqueous liquid compositions include emulsions, microemulsifiable concentrates, DC agents (dispersible concentrates), and OD agents (oil dispersions).

[0258] Common types of solid compositions include powders, granules, pellets, prills, aromatic tablets, tablets, and filled films (including seed coatings), which may be water-dispersible ("hydrated") or water-soluble. Films and coatings formed from film-forming solutions or fluid suspensions are particularly useful for seed treatment. Active ingredients can be (micro)encapsulated to form further suspensions or solid dosage forms; or the entire formulation of the active ingredient can be encapsulated (or "coated"). Encapsulation can control or delay the release of the active ingredient. Emulsifiable granules combine the advantages of both emulsion and dry granule formulations. High-strength compositions are mainly used as intermediates for further formulation.

[0259] Sprayable formulations are typically spread in a suitable medium before spraying. Such liquid and solid formulations are formulated to be easily diluted in a spray medium, usually water, but may also be another suitable medium such as aromatic or paraffinic hydrocarbons or vegetable oils. Spray rates can range from approximately 1 liter to several thousand liters per hectare, but more typically from approximately 10 liters to several hundred liters per hectare. Sprayable formulations can be tank-mixed with water or another suitable medium for foliar treatment by aerial or ground spraying, or for application to the plant's growth medium. Liquid and dry formulations may be measured and added directly into drip irrigation systems or measured and added between rows during sowing.

[0260] The formulation typically contains effective amounts of an active ingredient, diluent, and surfactant within a suitable range, totaling 100% by mass.

Such formulation aids and additives can control: pH (buffering agents), foaming during processing (antifoaming agents such as polyorganosiloxanes), sedimentation of active ingredients (suspending agents), viscosity (thixotropic thickeners), microbial growth in containers (antimicrobial agents), product freezing (antifreeze agents), color (pigment / dye dispersion), washability (film-forming agents or stickers), evaporation (evaporation retarders), and other formulation attributes. Examples of film-forming agents include polyvinyl acetate, polyvinyl acetate copolymers, polyvinylpyrrolidone-vinyl acetate copolymers, polyvinyl alcohol, polyvinyl alcohol copolymers, and waxes. Examples of formulation aids and additives are listed in McCutcheon's Volume 2: Functional Materials, annual international and North American editions, published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co., as well as in PCT publication WO 03 / 024222.

[0270] Compounds of formula I and any other active ingredients are typically incorporated into the compositions of the present invention by dissolving the active ingredients in a solvent or by grinding them in a liquid or dry diluent. Liquid formulations containing emulsions can be prepared simply by mixing the ingredients. If the solvent of a liquid composition intended for use as an emulsion is water-immiscible, an emulsifier is typically added to emulsify the solvent containing the active ingredients when diluted with water. Slurries of active ingredients having particle sizes up to 2,000 μm can be wet-ground using a medium mill to obtain particles with an average diameter of less than 3 μm. Aqueous slurries can be made into finished SC formulations (see, for example, US3,060,084) or further processed by spray drying to form hydrated granules. Dry formulations typically require a dry grinding process, which results in an average particle size in the range of 2 to 10 μm. Powders and powders can be prepared by mixing and usually grinding (e.g., using a hammer mill or fluid energy mill). Granules and pellets can be prepared by spraying the active substance onto a pre-formed granular carrier or by flocculation techniques. See Browning, "Agglomeration," Chemical Engineering, December 4, 1967, pp. 147–48; Perry's Chemical Engineer's Handbook, 4th edition, McGraw-Hill, New York, 1963, pp. 8–57; and below, as well as WO91 / 13546. Pellets may be manufactured as described in US4,172,714. Hydrated and water-soluble granules may be manufactured as taught in US4,144,050, US3,920,442 and DE3,246,493.

[0282] Examples A to I described above are also disclosed, in which compound number 22 is replaced with compound number 20, compound number 21, or compound number 65.

[0283] The test results showed that certain compounds of formula I are active pre-emergence and / or post-emergence herbicides and / or plant growth regulators. Compounds of formula I generally showed the highest activity for post-emergence weed control (i.e., applied after weed seedlings emerge from the soil) and pre-emergence weed control (i.e., used before weed seedlings emerge from the soil). Many of these compounds are practical for widespread pre- and post-emergence weed control in areas where complete control of all vegetation is desirable, such as around fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, airports, riverbanks, irrigation and other waterways, around billboards, and main roads and railway structures. Many of the compounds of this disclosure are useful for selective control of grasses and broadleaf weeds in crop / weed mixes by selective metabolism of weeds in crops, or by selective activity at sites of physiological inhibition in crops and weeds, or by selective placement on or within mixed crop and weed environments. Those skilled in the art will see that preferred combinations of these selective factors within a compound or group of compounds can be readily determined by performing conventional biological and / or biochemical assays.

[0284] Compounds of formula I may exhibit resistance to important agricultural crops, including, but are not limited to, perpetually cultivated crops such as alfalfa, barley, cotton, wheat, rapeseed, sugar beet, maize, sorghum, soybean, rice, oats, peanuts, vegetables, tomatoes, potatoes, coffee, cocoa, oil palm, rubber, sugarcane, citrus fruits, grapes, fruit trees, nut trees, bananas, plantains, pineapples, hops, and tea, as well as forests such as eucalyptus and conifers (e.g., pine), and turfgrass species (e.g., Kentucky bluegrass, St. Augustine grass, Kentucky fescue, and Bermuda grass). The compounds of this disclosure may be used in or on crops that have been genetically transformed or cultivated to incorporate resistance to herbicides, to express toxic proteins against invertebrate pests (e.g., Bacillus thuringiensis toxin), and / or to express other useful traits. As will be obvious to those skilled in the art, not all compounds are equally effective against all weeds. Alternatively, the compounds of the subject matter may be useful for modifying plant growth.

[0285] Since the compounds of this disclosure have activity for controlling undesirable vegetation by killing or damaging vegetation or reducing its growth (both pre- and post-emergence herbicides), the compounds can be usefully applied by various methods, including bringing a herbicidally effective amount of the compounds of this disclosure, or a composition comprising the compounds and at least one surfactant, solid diluent, or liquid diluent, into contact with the leaves or other parts of the undesirable vegetation, or with the environment of the undesirable vegetation, such as the soil or water surrounding the growing or seeds or other bulbils of the undesirable vegetation.

[0286] The effective amount of compound I in herbicides is determined by several factors. These factors include: Examples include the selected formulation, application method, amount and type of vegetation present, and growth conditions. Generally, the effective herbicidal dose of the compounds disclosed herein is about 0.001 to 20 kg / ha, with a preferred range of about 0.004 to 1 kg / ha. Those skilled in the art can easily determine the effective herbicidal dose required for a desired level of weed control.

[0287] In one general embodiment, the compound of formula I is typically applied in a formulated composition to a location containing both desirable vegetation (e.g., crops) and undesirable vegetation (i.e., weeds) in contact with a growth medium (e.g., soil), where both vegetation may be seeds, seedlings, and / or larger plants. In this location, the composition containing the compound of the present disclosure may be applied directly to the plants of the particularly undesirable vegetation or to a portion thereof, and / or to the growth medium in contact with the plants.

[0288] Fine varieties and cultivars of plants of a desired vegetation in a site treated with the compounds of this disclosure can be obtained by conventional propagation and breeding methods or by genetic engineering methods. Genetically modified plants (transgenic plants) are those in which a different gene (introduced gene) is stably incorporated into the plant genome. Depending on its specific location in the plant genome The introduction of a specified gene is called a transformation or transgenic event.

[0289] Most typically, the compounds of this disclosure are applied to control undesirable vegetation, but contact of the compounds of this disclosure with the desired vegetation at the treated site may produce additive or synergistic effects with the genetic traits of the desired vegetation, including traits incorporated through genetic modification. For example, resistance to herbivorous insect pests or plant diseases, tolerance to biotic / abiotic stress, or storage stability may be higher than what would be expected from the genetic traits of the desired vegetation.

[0290] The compounds of this disclosure can also be mixed with one or more other biologically active compounds or agents to form multicomponent pesticides that provide a broader range of agricultural protection, such as herbicides, herbicide phytotoxicity reducers, fungicides, insecticides, nematicides, bactericides, acaricides, growth regulators, such as insect molting inhibitors and rooting stimulants, chemical sterilizers, signaling substances, repellents, attractants, pheromones, contact irritants, plant nutrients, other biologically active compounds, or entomopathogenic bacteria, viruses, or fungi. Mixtures of the compounds of this disclosure with other herbicides can broaden the range of activity against further weed species and suppress the growth of any resistant biotypes. Accordingly, this disclosure also relates to a composition comprising a compound of formula I (in a herbicidally effective amount) and at least one further biologically active compound or agent (in a biologically effective amount), which may further comprise at least one surfactant, solid diluent, or liquid diluent. Other biologically active compounds or agents may be formulated into compositions comprising at least one surfactant, solid, or liquid diluent. The mixtures of the present disclosure may include one or more other biologically active compounds or agents formulated together with the compound of formula I to form a premix, or one or more other biologically active compounds or agents may be formulated separately from the compound of formula I, and these formulations may be mixed before application (e.g., in a spray tank) or applied sequentially.

[0291] For general references on agricultural protective agents (i.e., herbicides, herbicide phytotoxicity reducers, insecticides, fungicides, nematicides, acaricides, and biological agents), see The Pesticide Manual, 13th edition, CDSTomlin, Ed., British Crop References include the Protection Council, Farnham, Surrey, UK, 2003, and The BioPesticide Manual, 2nd edition, LGCopping, Ed., British Crop Protection Council, Farnham, Surrey, UK, 2001.

[0292] In embodiments in which one or more of these various mixing partners are used, the mixing partners are typically used in amounts similar to the usual amounts used when the mixing partner is used alone. More specifically, in the mixture, the active ingredient is often applied at a dosage between half and the full dosage specified on the product label for use of the active ingredient alone. These amounts are listed in references such as The Pesticide Manual and The BioPesticide Manual. The mass ratios of these various mixing partners (in total) to the compound of Formula I are typically between about 1:3000 and about 3000:1. In particular, mass ratios between about 1:300 and about 300:1 (e.g., ratios between about 1:30 and about 30:1). Those skilled in the art can easily determine the biologically effective amount of the active ingredient required for the desired range of biological activity by simple experiments. It will be apparent that including these additional components can broaden the range of weeds controlled beyond the range controlled by the compound of Formula I alone.

[0293] Of particular note is that the compound of the present invention (in an effective amount for herbicidal control), other herbicides, and herbicide phytotoxicity reducers... The composition comprises at least one further active ingredient (in an effective amount) selected from the group, and at least one component selected from the group consisting of surfactants, solid diluents, and liquid diluents.

[0294] Table A1 lists specific combinations of component (a) and component (b) that are useful in describing the mixtures, compositions, and methods of the present invention. Compound number 1 in the component (a) column (i.e., "Cpd. No." represents "compound number") is identified in Table AA. The second column of Table A1 lists specific compounds of component (b) (e.g., "2,4-D" in the first row). The third, fourth, and fifth columns of Table A1 list the range of mass ratios of the amount of compound (a) typically applied to outdoor crops to component (b) (i.e., (a):(b)). Thus, for example, the first row of Table A1 specifically discloses that the combination of component (a) (i.e., compound number 1 in Table AA) with 2,4-D is typically applied in a mass ratio between 1:192 and 6:1. The remaining rows of Table A1 should be interpreted similarly.

[0295] [Table 17] [Table 18] [Table 19] [Table 20] [Table 21] [Table 22]

[0296] Table A2 shows that the items under the column heading "Component (a)" represent each of the components (a) shown below. Except for the substitution of items in the column, it is interpreted as being the same as Table A1 above. Compound number 2 in the Component (a) column is identified in Table AA. Therefore, for example in Table A2, all items under the heading of the "Component (a)" column should list compound number 2 (i.e., compound number 2 identified in Table AA), and the first row under the heading of the column in Table A2 specifically discloses a mixture of compound number 2 and 2,4-D.

[0297] [Table 23]

[0298] In certain cases, combinations of the compounds of this disclosure with other biologically active (particularly herbicidal) compounds or agents (i.e., active ingredients) may produce a more-than-additive (i.e., synergistic) effect on weeds and / or a less-than-additive effect (i.e., phytotoxicity reduction) on crops or other desired plants. It is always desirable to reduce the amount of active ingredients released into the environment while ensuring effective pest control. The ability to provide more effective weed control using a larger amount of active ingredients without excessive crop damage is also desirable. When a synergistic effect of herbicidal active ingredients occurs on weeds at application rates that produce an agronomically sufficient level of weed control, such combinations may be advantageous in reducing crop production costs and decreasing environmental impact. When phytotoxicity reduction of herbicidal active ingredients occurs on crops, such combinations may be advantageous in increasing crop protection by reducing weed competition.

[0299] Of particular note are combinations of the compounds of this disclosure with at least one other herbicidal active ingredient. Of particular note are combinations in which the other herbicidal active ingredient has a different site of action than the compounds of this disclosure. In certain examples, combinations with at least one other herbicidal active ingredient having a similar control range but a different site of action are particularly useful for resistance management. It would be beneficial. Therefore, the compositions of the present disclosure may further contain (in an effective herbicidal amount) at least one additional herbicidal active ingredient having a similar control range but a different site of action.

[0300] The compounds disclosed herein also include alidocrol, benoxacol, croquintoset-mexyl, cumylon, cyometrinil, cyprosulfonamide, dimuron, dichlormid, dicyclonon, dietholate, dimepiperate, fenchlorazole-ethyl, fenchlorim, flurazole, fluxofenim, flirazole, isoxadifen-ethyl, mefenpyr-diethyl, mephenate, methoxyphenone, naphthalic anhydride (1,8-naphthalic anhydride), oxavethrinil, N-(aminocarbonyl)-2-methylbenzenesulfonamide, N-(aminocarbonyl)-2-fluorobenzenesulfonamide, and 1-bromo-4-[(chloro-methyl)-sulfonyl]-benzene. (BCS), 4-(dichloroacetyl)-1-oxa-4-azospiro[4.5]decane (MON 4660), 2-(dichloromethyl)-2-methyl-1,3-dioxolane (MG191) can be used in combination with herbicide reducers such as ethyl 1,6-dihydro-1-(2-methoxyphenyl)-6-oxo-2-phenyl-5-pyrimidinecarboxylate, 2-hydroxy-N,N-dimethyl-6-(trifluoromethyl)pyridine-3-carboxamide, 1-(3,4-dimethylphenyl)-1,6-dihydro-6-oxo-2-phenyl-5-pyrimidine carboxylate, 2,2-dichloro-1-(2,2,5-trimethyl-3-oxazolidinyl)-ethanone and 2-methoxy-N-[[4-[[(methylamino)carbonyl]amino]phenyl]sulfonyl]-benzamide to increase safety for certain crops. A detoxifying amount of the herbicide reducer may be applied simultaneously with the compounds of this disclosure or as a seed treatment. Accordingly, one aspect of the present disclosure relates to a herbicide mixture comprising the compounds of the present disclosure and an effective amount of herbicide phytotoxicity reducer. Seed treatment is particularly useful for selective weed control because it physically limits detoxification to crop plants.Therefore, a particularly useful embodiment of the present disclosure is a method for selectively controlling the growth of undesirable vegetation on a crop, comprising contacting the crop site with a herbicidally effective amount of the compound of the present disclosure, where the crop and the seeds from which it grows are treated with a detoxifyingly effective amount of the phytotoxicity reducer. Those skilled in the art can readily determine the detoxifyingly effective amount of the phytotoxicity reducer by simple experiments.

[0301] The compounds of this disclosure may also be mixed with: (1) polynucleotides including, but not limited to, DNA, RNA, and / or chemically modified nucleotides that affect the amount of a particular target by downregulating, interfering with, repressing or silencing genetically induced transcripts to confer a herbicidal effect; or (2) polynucleotides including, but not limited to, DNA, RNA, and / or chemically modified nucleotides that affect the amount of a particular target by downregulating, interfering with, repressing or silencing genetically induced transcripts to confer a phytotoxicity-reducing effect.

[0302] The following tests A-M demonstrate the control efficacy of representative compounds of this disclosure against typical weeds, but the weed control provided by these compounds is not limited to these species. See Index Table 1 for a description of the compounds. The mass spectra were observed using atmospheric pressure chemical ionization (AP+) to which H2 was directed onto the molecules. + The molecular weight of the parent ion (M+1) with the highest isotopic abundance formed by the addition of (molecular weight 1) is reported with an estimation accuracy of within ±0.5 Da.
