Detailed description of the invention As used herein, the terms "comprising", "comprising", "includes", "including", "has", "having", "contains", "containing", "characterized by" or any other variations hereof are intended to cover non-exclusive inclusion, subject to any explicitly stated limitations. For example, a process or method comprising a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition process or method. The transition phrase "consisting of" excludes any unspecified element, stage, or ingredient. If in the claim, this would close the claim to the inclusion of materials other than those listed except for impurities normally associated with them. When the phrase "consisting of" appears in a clause of the body of a claim, instead of immediately following the preamble, it limits only the element stated in that clause; other elements are not excluded from the claim as a whole. The transition phrase "consisting essentially of" is used to define a process or method that includes materials, steps, features, components, or items, in addition to those described literally, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel features of the description. The term "consisting essentially of" occupies a foreground between "comprising" and "consisting of". Where applicants have defined the description or a part thereof with an indefinite term such as "comprising", it should be readily understood that (unless otherwise stated) the description should also be construed to describe such description using the terms " consisting essentially of” or “consisting of”. In addition, unless expressly stated otherwise, "or" refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by either of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). Also, the indefinite articles “a” and “uno / una” that precede an element or component of the description are intended not to be restrictive with respect to the number of instances (ie occurrences) of the element or component. Thus "a" or "a / an" should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously intended to be singular. As used herein, the term "Ci-Ce alkyl" includes straight-chain or branched alkyl groups having one to six carbon atoms, for example, methyl, ethyl, n-propyl, / -propyl, or the various isomers. butyl, pentyl, or hexyl. Likewise, the term "C1-C4 alkyl" includes branched or straight chain alkyl having one to four carbon atoms, for example, methyl, ethyl, n-propyl, / -propyl, or the different butyl isomers, and the The term "C1-C3 alkyl" includes methyl, ethyl, n-propyl, and / -propyl. As used herein, the term "halogen" includes fluoro, chloro, bromo or iodo. When G is "SO2(4-Me-Ph)" this is alternatively defined as "S02(p-tolyl)". The term "reacting" and the like refer to adding, contacting, or mixing two or more reactants under appropriate conditions to produce the indicated and / or desired product. It should be appreciated that the reaction that produces the indicated and / or the desired product may not necessarily result directly from the combination of two reactants that were initially added, that is, there may be one or more intermediates that occur in the mixture that ultimately leads to to the formation of the indicated and / or the desired product. Reacting can take place in the presence or absence of solvent, at a temperature above or below room temperature, under an inert atmosphere, etc. The term "methoxylating agent" as used herein refers to a chemical reagent used to add a methoxy group, that is, OCH3, to a compound. Exemplary non-limiting methoxylating agents include sodium methoxide or potassium methoxide. The term "tmp-zinc base" as used herein refers to a chemical complex comprising zinc and 2,2,6,6-tetramethylpiperidine. Exemplary non-limiting zinc bases include (tmp)2Zn-2 MgCb-2 LiCI. (tmp)2Zn-2 LiCI and (tmpjzZn. The term "halogenating agent" as used herein refers to a chemical reagent used to add a halogen atom, eg, Cl, Br, or I, to a compound. Exemplary non-limiting halogenating agents include iodine, 1,3-dichloro-5,5-dimethylhydantoin, 1,3-dibromo-5,5dimethylhydantoin, 1,3-diiodo-5,5-dimethylhydantoin , trichloroisocyanuric acid, sulfuryl chloride, N-bromosuccinimide and / V-chlorosuccinimide. compounds of Formula I typically exist in more than one solid form. Thus, the compounds of Formula I include all crystalline and non-crystalline forms of the compounds they represent. Non-crystalline forms include modalities that are solid such as waxes and gums as well as modalities that are liquid such as orodispersible tablets and solutions. Crystal forms include modalities that essentially represent a single crystal type and modalities that represent a mixture of polymorphs (ie different crystal types). The term "polymorph" refers to a particular crystalline form of a chemical compound that can crystallize in different crystalline forms, these forms having different configurations and / or conformations of the molecules in the crystal lattice. Although polymorphs may have the same chemical composition, also ncccnn / i 7Π7 / Β / Υ may differ in composition due to the presence or absence of co-crystallized water or other molecules, which may be loosely or strongly linked in the lattice. Polymorphs may differ in such chemical, physical, and biological properties as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspendability, dissolution rate, and biological availability. One skilled in the art will appreciate that one polymorph of a compound of Formula I may exhibit beneficial effects (eg, convenience for the preparation of useful formulations, improved biological performance) relative to another polymorph or a mixture of polymorphs of the same compound of Formula I. Formula I. The preparation and isolation of a particular polymorph of a compound of Formula I can be accomplished by methods known to those skilled in the art including, for example, crystallization using selected solvents and temperatures. For a comprehensive discussion of polymorphism see R. Hilfiker, Ed., Polymorphism in the Pharmaceutical Industry, WileyVCH, Weinheim, 2006. Synthetic methods for the preparation of / V-oxides of heterocycles and tertiary amines are well known to one skilled in the art. Exemplary procedures for preparing / V-oxides include the oxidation of heterocycles and tertiary amines with peroxyacids such as peracetic and m-chloroperbenzoic acid (MCPBA), acid peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as as dimethyldioxirane. These methods for the preparation of / V-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S.V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J. Boulton and A. McKillop, Eds., Pergamon Press; M.R. Grimmett and B.R.T. Keene in Advances in Heterocyclic Chemistry, vol. 43, pp 149-161, A.R. Katritzky, Ed., Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemistry, vol. 9, pp 285-291, A.R. Katritzky and A.J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk in Advances in Heterocyclic Chemistry, vol. 22, pp 390-392, A.R. Katritzky and A.J. Boulton, Eds., Academic Press. That said, one skilled in the art will appreciate that not all nitrogen-containing heterocycles can form / V-oxides since nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen-containing heterocycles that can form / V-oxides. One skilled in the art recognizes that because in the environment and under physiological conditions the salts of chemical compounds are in equilibrium with their corresponding non-salt forms, the salts share the biological utility of the non-salt forms. Thus, a wide variety of salts of a compound of Formula I are useful for the control of unwanted vegetation (ie they are agriculturally suitable). Salts of a compound of Formula I include acid addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric.

The invention also includes a herbicide mixture comprising (a) a compound selected from Formula 1, / V-oxides, and salts thereof, and (b) at least one additional active ingredient selected from (b1) photosystem inhibitors II, (b2) acetohydroxy acid synthase (AHAS) inhibitors, (b3) acetyl-CoA carboxylase (ACCase) inhibitors, (b4) auxin mimics, (b5) 5-enol-pyruvilsh¡kimate-3 synthase mimics -phosphate (EPSP), (b6) photosystem I electron deflectors, (b7) protoporphyrinogen oxidase (PPG) inhibitors, (b8) glutamine synthetase (GS) inhibitors, (b9) fatty acid chain elongase inhibitors very long (VLCFA), (b10) auxin transport inhibitors, (b11) phytoene desaturase (PDS) inhibitors, (b12) 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, (b13) solenesyltransererase homogentisate inhibitors ( HST), (b14) cellulose biosynthesis inhibitors, (b15) other herbicides including mitotic disruptors, organic arsenicals, asulam, bromobutide, cinmethylin, cumyluron, dazomet, difenzoquat, ncccnn / i ζπζ / β / υ dymron, etobenzanid , flurenol, fosamine, fosamine-ammonium, hydantocidin, metam, methyldymron, oleic acid, oxaziclomefone, pelargonic acid and pyributicarb, and (b16) herbicide protectants; and salts of compounds from (b1) to (b16). "Photosystem II inhibitors" (b1) are chemical compounds that bind to the D-1 protein in the Qb-binding niche and thus block electron transport from Qa to Qb in chloroplast thylakoid membranes. Electrons blocked from passing through photosystem II are transferred through a series of reactions to form toxic compounds that disrupt cell membranes and cause chloroplast swelling, membrane leakage, and ultimately cell destruction. The Qb binding niche has three different binding sites: the A binding site binds triazines such as atrazine, triazinones such as hexazinone, and uracils such as bromacil, the B binding site binds phenylureas such as diuron, and the binding site C binds benzothiadiazoles such as bentazon, nitriles such as bromoxynil, and phenyl-pyridazines such as pyridate. Examples of photosystem II inhibitors include ametryn, amicarbazone, atrazine, bentazon, bromacil, bromophenoxim, bromoxynil, chlorbromuron, chloridazon, chlorotoluron, cloroxuron, cumyluron, cyanazine, daimuron, desmedipham, desmetryn, dimefuron, dimethamethrin, diuron, etidimuron, fenuron, flu ometuron , hexazinone, ioxynil, isoproturon, isouron, lenacil, linuron, metamitron, metabenzthiazuron, metobromuron, metoxuron, metribuzin, monolinuron, neburon, pentanochlor, phenmedipham, prometon, promethrin, propanil, propazine, pyridafol, pyridate, siduron, simazine, simethrin, tebuthiu ron , terbacil, terbumeton, terbutylazine, terbutrin and triethazine. "AHAS inhibitors" (b2) are chemical compounds that inhibit acetohydroxy acid synthase (AHAS), also known as acetolactate synthase (ALS), and thus kill plants by inhibiting the production of branched-chain aliphatic amino acids such as valine, leucine and isoleucine, which are required for protein synthesis and cell growth. Examples of AHAS inhibitors include amidosulfuron, azimsulfuron, bensulfuron-methyl, bispyribac-sodium, chloransulam-methyl, chlorimuron-ethyl, chlorsulfuron, cinosulfuron, cyclosulfamuron, diclosulam, ethametsulfuron-methyl, ethoxysulfuron, flazasulfuron, florasulam, flucarbazone-sodium, flumetsulam, flupyrsulfuron -methyl, flupyrsulfuron-sodium, foramsulfuron, halosulfuronmethyl, imazametabenz-methyl, imazamox, imazapic, imazapyr, imazaquin, imazethapyr, imazosulfuron, iodosulfuron-methyl (including sodium salt), iofensulfuron (2-iodo- / V-[[( 4-methoxy-6-methyl-1,3,5-triazin-2yl)amino]carbonyl]benzenesulfonamide), mesosulfuron-methyl, metazosulfuron (3-chloro-4-(5,6-dihydro-5methyl-1, 4,2-dioxazin-3-yl)- / \ / -[[(4,6-dimethoxy-2-p¡r¡m¡n¡l)am¡no]carbon¡l]-1 -methyl-1 / 7-pyrazole-5-sulfonamide), metosulam, metsulfuron-methyl, nicosulfuron, oxasulfuron, penoxsulam, primisulfuron-methyl, propoxycarbazone-sodium, propyrisulfuron (2-chloro- / V-[ [(4,6-dimethoxy¡-2-pyrimidin¡l)amino]carbon¡l]-6propylimidazo[1,2-jb]pyr¡daz¡na-3-sulfonam¡de), prosulfuron, pyrazosulfuron -ethyl, pyribenzoxim, pyriphthalid, pyriminobac-methyl, pyrithiobac-sodium, rimsulfuron, sulfometuron-methyl, sulfosulfuron, thiencarbazone, thifensulfuron-methyl, triafamone (A / -[2-[(4,6-dimethoxy-1,3,5 -triazin-2-¡l)carbon¡l]-6-fluorophenyl]-1,1 -difluoro- / \ / methylmethanesulfonamide), triasulfuron, tribenuron-methyl, trifloxysulfuron (including sodium salt), triflusulfuron -methyl and tritosulfuron. "ACCase inhibitors" (b3) are chemical compounds that inhibit the enzyme acetyl-CoA ncccnn / i 7Π7 / Ε / Υ carboxylase, which is responsible for catalyzing an early step in the synthesis of lipids and fatty acids in plants. Lipids are essential components of cell membranes, and without them, new cells cannot be produced. The inhibition of acetyl CoA carboxylase and the subsequent lack of lipid production leads to losses in cell membrane integrity, especially in regions of active growth such as meristems. Eventually, shoot and rhizome growth ceases, and shoot meristems and rhizome buds begin to die. Examples of ACCase inhibitors include alloxydim, butroxydim, clethodim, clodinafop, cycloxydim, cyhalofop, diclofop, fenoxaprop, fluazifop, haloxyfop, pinoxaden, profoxydim, propaquizafop, quizalofop, sethoxydim, tepraloxydim, and tralkoxydim, including resolved forms such as fenoxaprop- P, fluazifop -P, haloxyfop-P and quizalofop-P and ester forms such as clodinafop-propargyl, cyhalofop-butyl, diclofop-methyl and fenoxaprop-P-ethyl. 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, thereby causing uncontrolled and disorganized growth leading 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 and their sodium and potassium salts, aminopyralid, benazolin-ethyl, chloramben, clacifos, clomeprop, clopyralid, dicamba, 2,4-D, 2,4-DB, dichlorprop, fluroxypyr, halauxifen (4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylic acid), halauxifen-methyl (methyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylate), MCPA, MCPB, mecoprop, picloram, quinclorac, quinmerac, 2,3 ,6-TBA, triclopyr, and methyl 4-amino-3chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-5-fluoro-2-pindincarboxylate. "EPSP synthase inhibitors" (b5) are chemical compounds that inhibit the enzyme, 5-enol-pyruvylshikimate-3-phosphate synthase, which is involved in the synthesis of aromatic amino acids such as tyrosine, tryptophan and phenylalanine. EPSP inhibitor herbicides are readily absorbed through the foliage of plants and are carried in the phloem to growing points. Glyphosate is a relatively non-selective post-emergence herbicide that belongs to this group. Glyphosate includes esters and salts such as ammonium, isopropylammonium, potassium, sodium (including sesquisodium), and trimesium (alternatively called sulfosate). “Photosystem I electron deflectors” (b6) are chemical compounds that accept electrons from Photosystem I, and after several cycles, generate hydroxyl radicals. These radicals are extremely reactive and readily destroy unsaturated lipids, including membrane fatty acids and chlorophyll. This destroys the integrity of the cell membrane, so that the cells and organelles "leak", which leads to wilting and rapid desiccation of the leaves, and eventually death of the plants. Examples of this second type of photosynthesis inhibitor include diquat and paraquat. "PPO inhibitors" (b7) are chemical compounds that inhibit the enzyme protoporphyrinogen oxidase, rapidly resulting in the formation of highly reactive compounds in plants that rupture cell membranes, causing leakage of cell fluids. Examples of PPO inhibitors include acifluorfen-sysodium, azafenidin, benzfendizone, biphenox, butafenacil, carphantrazone, carphantzone ncccnn / i 7π7 / β / υ ethyl azin, fluorographic feet, fluthiacet-methyl, fomesafen, halosafen, lactofen, oxadiargyl, oxadiazon, oxyfluorfen, pentoxazone, profluazole, pyraclonil, pyraflufen-ethyl, saflufenacil, sulfentrazone, tidiazimin, trifludimoxazin (dihydro-1,5dimethyl-6-thioxo-3-[2 ,2,7-trifluoro-3,4-dihydro-3-oxo-4-(2-propyn-1-11)-2 / - / -1,4-benzoxazin-6-yl]-1 ,3,5-triazine2,4(1 / - / ,3 / - / )-dione) and thiafenacil ( / V-[2-[[2-chloro-5-[3,6-d¡h¡dro- 3-methyl-2,6-d¡oxo-4-(trifluoromethyl)-1 (2 / - / )pyrimid¡n¡l]-4-fluorophenyl]thio]-1 -oxopropyl]-p-alaninate methyl). “GS inhibitors” (b8) are chemical compounds that inhibit the activity of the glutamine synthetase enzyme, which plants use to convert ammonia into glutamine. Consequently, ammonia accumulates and glutamine levels decrease. Plant damage is probably due to the combined effects of ammonia toxicity and deficiency of amino acids required for other metabolic processes. GS inhibitors include glufosinate and its esters and salts such as glufosinatoammonium and other phosphinothricin derivatives, glufosinate-P((2S)-2-amino-4-(hydroxymethylphosphinyl)butanoic acid), and bilanafos. "VLCFA elongase inhibitors" (b9) are herbicides having a wide variety of chemical structures, which inhibit elongase. Elongase is one of the enzymes located in or near chloroplasts that are involved in VLCFA biosynthesis. In plants, very long chain fatty acids are the main constituents of hydrophobic polymers that prevent desiccation on the leaf surface and provide stability to pollen grains. Such herbicides include acetochlor, alachlor, anilophos, butachlor, cafenstrol, dimethachlor, dimethenamide, diphenamide, phenoxasulfone (3-[[(2,5-dichloro-4-ethoxyphenyl)methyl]sulfonyl]-4,5-dihydro -5,5-dimethylsoxazole), fentrazamide, flufenacet, indanofan, mefenacet, metazachlor, metolachlor, naproanilide, napropamide, napropamide-M ((2R)- / V, / V-diethyl-2-(1 -naphthalenyloxy)propanamide), petoxamid, piperofos, pretilachlor, propachlor, propisochlor, pyroxasulfone, and thenylchlor, which includes resolved forms such as S-metolachlor and chloroacetamides and oxyacetamides. "Auxin transport inhibitors" (b10) are chemicals that inhibit auxin transport in plants, such as by binding to an auxin transporter protein. Examples of auxin transport inhibitors include diflufenzopyr, naptalam (also known as N(1-naphthyl)phthalamic acid and 2-[(1-naphthalenylamino)carbonyl]benzoic acid). "PDS inhibitors" (b11) are chemical compounds that inhibit the carotenoid biosynthesis pathway at the phytoene desaturase stage. Examples of PDS inhibitors include beflubutamid, diflufenican, fluridone, flurochloridone, flurtamone, norflurzon, and picolinafen. "HPPD inhibitors" (b12) are chemicals that inhibit the biosynthesis of 4-hydroxyphenyl-pyruvate dioxygenase synthesis. Examples of HPPD inhibitors include benzobicyclone, benzofenap, bicyclopyrone (4-h¡drox¡-3-[[2-[(2-methoxyethoxy¡)methyl]-6-(trifluoromethyl)-3-p¡ r¡d¡n¡l]carbon¡l]b¡c¡clo[3.2.1]oct-3en-2-one), phenquinotrione (2-[[8-chloro-3,4-dih¡dro-4 -(4-methox¡phenyl)-3-oxo-2-qu¡noxal¡n¡l]carbonyl]-1,3cyclohexanedione), isoxachlortole, isoxaflutole, mesotrione, pyrasulfotol, pyrazolinate, pyrazoxifene, sulcotrione, tefuryltrione, tembotrione , tolpyralate (1-[[1-ethyl-4-[3-(2-methoxyethoxy)-2-methyl-4(methylsulfonyl)benzoyl]-1H-plrazol-5-yl]oxy]ethyl methyl carbonate), topramezone , 5-chloro-3-[(2-hydroxy-6-oxo-1 ncccnn / i 7Π7 / Β / Υ cyclohexen-1 -yl)carbonyl]-1 -(4-methoxyphenyl)-2(1H)-quinoxalinone , 4-(2,6-diethyl-4-methylphenyl)-5-hydroxy-2,6dimethyl-3(2 / 7)-pyridazinone, 4-(4-fluorophenyl)- 6-[(2-hydroxy-6-oxo-1 -cyclohexen-1 -i I) ca rcarbon i l]-2-m ethyl-1,2,4triazine-3,5(2 / 7,4 / 7)- Dione, 5-[(2-hydroxy-6-oxo-1-cyclohexen-1-yl)carbonyl]-2-(3-methoxyphenyl)-3-(3methoxypropyl)-4(3 / 7 )-pyrimidnone, 2-methyl- / V-(4-methyl-1,2,5-oxadiazol-3-yl)-3-(methylsulfinyl)-4(tnfluoromethyl)benzamide and 2-methyl -3-(methylsulfonyl)- / V-(1-methyl-1 / 7-tetrazol-5-yl)-4-(trifluoromethyl)benzamide. "HST inhibitors" (b13) alter a plant's ability to convert homogentisate to 2-methyl-6-solanyl-1,4-benzoquinone, thus altering carotenoid biosynthesis.

They are most effective when applied pre-emergence or post-emergence early on young or fast-growing plants. Examples of cellulose biosynthesis inhibitors include chlorthiamide, dichlobenil, flupoxam, indaziflam (Λ / 2-[(1 / ?,2S)-2,3-dihydro-2,6-dimethyl-1Hinden-1-yl] -6-(1 -fluoroethyl)-1,3,5-triaz¡na-2,4-d¡am¡na), isoxaben and triaziflam. “Other herbicides” (b15) include herbicides that act through a variety of different modes of action such as mitotic disruptors (for example, flamprop-M-methyl and flamprop-Misopropyl), organic arsenicals (for example, DSMA, and MSMA ), inhibitors of 7,8-dihydropteroate synthase, inhibitors of chloroplast isoprenoid synthesis, and inhibitors of cell wall biosynthesis.

A compound of Formula I will generally be used as a herbicidal active ingredient in a composition, ie formulation, with at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents. In certain embodiments, the additional component can serve as a carrier. Formulation or composition ingredients are selected according to the physical properties of the active ingredient, mode of application and environmental factors such as soil type, humidity and temperature. Useful formulations include both liquid and solid compositions comprising the compound of Formula I. Liquid compositions include solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions, oil-in-water emulsions, flowable concentrates, and / or suspoemulsions) and the like, which can optionally be thickened into gels. General types of aqueous liquid compositions are soluble concentrates, suspension concentrate, capsule suspension, emulsion concentrate, microemulsion, oil-in-water emulsion, flowable concentrate, and suspo-emulsion. General types of non-aqueous liquid compositions are emulsifiable concentrate, microemulsifiable concentrate, dispersible concentrate, and oil dispersion. General types of solid compositions are dusts, powders, granules, pellets, granulated particles, tablets, tablets, filled films (including seed coatings), and the like, which may be water-dispersible ("wettable") or soluble. in water. Films and coatings formed from film-forming solutions or fluid suspensions are particularly useful for seed treatment. The active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire active ingredient formulation can be encapsulated (or "coated"). The encapsulation may control or delay the release of the active ingredient. An emulsifiable granule combines the advantages of both an emulsifiable concentrate formulation and a dry granular formulation. High strength compositions are used primarily as intermediates for further formulation. Sprayable formulations are typically spread in a suitable medium prior to spraying. Such liquid and solid formulations are formulated to be easily diluted in the spray medium, generally water, but occasionally another suitable medium such as an aromatic or paraffinic hydrocarbon or vegetable oil. Spray Volumes can range from about one to several thousand liters per hectare, but more typically are in the range of about ten to several hundred liters per hectare. The sprayable formulations can be tank-mixed with water or other suitable medium for foliar treatment by aerial or ground application, or for application to the growing medium of the plant. Liquid and dry formulations can be measured directly into drip irrigation systems or measured in the furrow during planting. Formulations will typically contain effective amounts of active ingredient, diluent, and surfactant within the following approximate ranges that add up to 100 percent by weight. ncccnn / i ζηζ / Β / γ Percent by Weight Active Ingredient Diluent Surfactant Granules, Tablets and Powders 0.001-90 0-99.999 0-15 Water Dispersible and Water Soluble Dispersion in Oils, Suspensions, Emulsions, Solutions (including Emulsifiable Concentrates) 1-50 40-99 0 -50 Powders 1-25 70-99 0-5 Granules and Pellets 0.001-99 5-99.999 0-15 High Strength Compositions 90-99 0-10 0-2 Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, gypsum, cellulose, titanium dioxide, zinc oxide, starch, dextrin, sugars (for example, lactose, sucrose), silica, talc, mica, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate.

Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. The solid and liquid compositions of the present disclosure often include one or more surfactants. When added to a liquid, surfactants (also known as "surfactants") usually modify, more often reduce, the surface tension of the liquid. Depending on the nature of the hydrophilic and lipophilic groups in a surfactant molecule, surfactants may be useful as wetting, dispersing, emulsifying, or antifoaming agents. Surfactants can be classified as nonionic, anionic, or cationic.

Nonionic, Anionic, and Cationic Surfactants and their recommended uses are described in a variety of published references including McCutcheon's Emulsifiers and Detergents, annual American and International Editions published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964; and A. S. Davidson and B. Milwidsky, Synthetic Detergents, Seventh Edition, John Wiley and Sons, New York, 1987. The compositions of this disclosure may also contain formulation auxiliaries and additives, known to those skilled in the art as formulation aids (some of which may be considered to also function as solid diluents, liquid diluents, or surfactants). Such formulation auxiliaries and additives can control: pH (buffers), foaming during processing (defoamers such as polyorganosiloxanes), settling of active ingredients (suspending agents), viscosity (thixotropic thickeners), microbial growth in the container (antimicrobials ), product freezing (antifreeze), color (dye / pigment dispersions), washout period (film formers or self-adhesives), evaporation (evaporation retardants), and other formulation attributes. Film formers include, for example, polyvinyl acetates, polyvinyl acetate copolymers, polyvinylpyrrolidone-vinyl acetate copolymer, polyvinyl alcohols, polyvinyl alcohol copolymers, and waxes. Examples of formulation auxiliaries and additives include those listed in McCutcheon's Volume 2: Functional Materials, International and North American annual editions published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; and PCT Publication WO 03 / 024222. The compound of Formula I and any other active ingredients are typically incorporated ncccnn / i 7Π7 / Β / Υ into the present compositions by dissolving the active ingredient in a solvent or by grinding in a liquid or dry diluent. Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. If the solvent of a liquid composition intended for use as an emulsifiable concentrate is insoluble in water, an emulsifier is typically added to emulsify the active-containing solvent upon dilution with water. Thick active ingredient mixtures with particle diameters up to 2,000 µm can be wet-milled using media mills to obtain particles with average diameters below 3 µm. Aqueous slurries can be made into finished suspension concentrates (see, for example, U.S. 3,060,084) or further processed by spray drying to form water-dispersible granules. Dry formulations generally require dry milling processes, which produce average particle diameters in the range of 2 to 10 pm. Dusts and powders can be prepared by mixing and generally grinding (such as with a hammer mill or fluid energy mill). Granules and pellets can be prepared by spraying the active material onto preformed granular carriers or by agglomeration techniques.

The test results indicate that the certain compounds of Formula I are active preemergence and / or postemergence and / or regulators of plant growth. Formula I compounds usually show the greatest activity for post-emergence weed control (that is, applied after weed seedlings emerge from the soil) and pre-emergence weed control (that is, applied before weed seedlings emerge). weed seedlings emerge from the soil). Many of them have utility for broad-spectrum pre- and / or post-emergence weed control in areas where complete control of all vegetation is desired such as around fuel storage tanks, industrial storage areas, parking lots, drive-ins, airfields, along river banks, irrigation and other waterways, around billboards and highway and railway structures. Many of the compounds of this description, by virtue of selective metabolism in crops versus weeds, or by selective activity at the site of physiological inhibition in crops and weeds, or by selective placement on or within the environment of a mixed crop and weed , are useful for the selective control of grass and broadleaf weeds within a crop / weed mixture. One skilled in the art will recognize that the preferred combination of these selective factors within a compound or group of compounds can readily be determined by performing routine biological and / or biochemical assays. Compounds of Formula I may show tolerance to important agronomic crops including, but not limited to, alfalfa, barley, cotton, wheat, rapeseed, sugar beet, grain (corn), sorghum, soybean, rice, oats, peanuts, vegetables, tomato, potato, perennial plantation crops including coffee, cocoa, oil palm, rubber, sugar cane, citrus, grapes, fruit trees, nut trees, banana, plantain, pineapple, hops, tea, and forests such as eucalyptus and conifers (eg, loblolly pine); and grass species (eg, Kentucky bluegrass, St. Augustine grass, Kentucky fescue, and Bermudagrass). The compounds of this disclosure can be used in or on crops genetically transformed or bred to incorporate resistance to herbicides, express proteins toxic to invertebrate pests (such as Bacillus thuringiensis toxin), and / or express other useful traits. Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful for modifying plant growth. As the compounds of the disclosure have activity (both pre-emergence and post-emergence herbicidal) to control unwanted vegetation by killing or injuring vegetation or reducing its growth, the compounds can be usefully applied by a variety of methods involving putting into contacting a herbicidally effective amount of a compound of the disclosure, or a composition comprising such a compound and at least one of a surfactant, a solid thinner or a liquid thinner, to foliage or other unwanted vegetation or to the environment of the unwanted vegetation such as the soil or water in which the unwanted vegetation is growing or surrounding the seed or other propagule of the unwanted vegetation. A herbicidally effective amount of a compound of Formula I is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general, a herbicidally effective amount of compounds of this description is about 0.001 to 20 kg / ha with a preferred range of about 0.004 to 1 kg / ha. One skilled in the art can readily determine the herbicidally effective amount necessary for the desired level of weed control. In a common embodiment, a compound of Formula I is applied, typically in a formulated composition, to a locus comprising desired vegetation (eg, crops) and unwanted vegetation (eg, weeds), both of which may be seeds. , seedlings and / or larger plants, in contact with a growing medium (eg soil). Here, a composition comprising a compound of the disclosure can be applied directly to a plant or part thereof, particularly unwanted vegetation, and / or to the growth medium in contact with the plant. ncccnn / i 7Π7 / Β / Υ Plant varieties and cultivars of the desired vegetation on the site treated with a compound of the disclosure may be obtained by conventional propagation and breeding methods or by genetic engineering methods. Genetically modified plants (transgenic plants) are those in which a heterologous gene (transgene) has been stably integrated into the plant genome. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event. Although more typically, compounds of the disclosure are used to control unwanted vegetation, contact of desired vegetation at the treated site with compounds of the disclosure may result in super-additive or synergistic effects with genetic traits on the desired vegetation, which includes traits incorporated through genetic modification. For example, resistance to phytophagous insect pests or plant diseases, tolerance to biotic / abiotic stresses, or storage stability may be higher than expected of the genetic traits in the desired vegetation. The compounds of this disclosure may also be mixed with one or more other biologically active compounds or agents including herbicides, herbicides, fungicides, insecticides, nematocides, bactericides, acaricides, growth regulators such as insect molting inhibitors, and stimulants. rooting agents, chemosterilants, semiochemicals, repellents, attractants, pheromones, feeding stimulants, plant nutrients, other biologically active compounds or entomopathogenic bacteria, viruses or fungi to form a multi-component pesticide that gives a broader uniform spectrum of agricultural protection. Mixtures of the compounds of the description with other herbicides can broaden the spectrum of activity against additional weed species, and suppress the proliferation of any of the resistant biotypes. Therefore, the present disclosure also pertains to a composition comprising a compound of Formula I (in a herbicidally effective amount) and at least one additional biologically active compound or agent (in a biologically active amount) and may further comprise at least one of a surfactant, a solid diluent or a liquid diluent. The other biologically active compounds or agents may be formulated into compositions comprising at least one of a solid or liquid surfactant, diluent. For mixtures of the present disclosure, one or more other biologically active compounds or agents may be formulated together with a 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 the formulations combined prior to application (eg, in a spray tank) or, alternatively, applied in succession. General references for crop protectants (i.e., herbicides, herbicide protectants, insecticides, fungicides, nematocides, acaricides, and biological agents) include The Pesticide Manual, 13th Edition, C. D. S. Tomlin, Ed., British Crop Protection Council, Farnham, Surrey, U.K., 2003 and The BioPesticide Manual, 2nd Edition, L. G. Copping, Ed., British Crop Protection Council, Farnham, Surrey, U.K., 2001. For embodiments where one or more of these various mixing partners are used, the mixing partners are typically used in amounts similar to usual amounts when ncccnn / i ζηζ / Β / γ the mixing partners are used alone. More particularly in mixtures, active ingredients are often applied at an application rate between half and the full application rate specified on product labels for active ingredient-only use. These amounts are listed in references such as The Pesticide Manual and The BioPesticide Manual. The weight ratio of these various mixing partners (in total) to the compound of Formula I is typically between about 1:3000 and about 3000:1. Weight ratios between about 1:300 and about 300:1 (eg ratios between about 1:30 and about 30:1) stand out. One skilled in the art can readily determine through simple experimentation the biologically effective amounts of active ingredients necessary for the desired spectrum of biological activity. It will be apparent that including these additional components can expand the spectrum of weeds controlled beyond the spectrum controlled by the compound of Formula I alone. Of note is a composition comprising a compound of the invention (in a herbicidally effective amount), at least one additional active ingredient selected from the group consisting of other herbicides and herbicidal protectants (in an effective amount), and at least one component selected from the group consisting of surfactants, solid diluents and liquid diluents. Table A1 lists specific combinations of a Component (a) with Component (b) illustrative of the mixtures, compositions, and methods of the present invention. Compound No. 1 (this is "Com. No." stands for "Compound Number") in the Component (a) column is identified in Table AA. The second column of Table A1 lists the specific Component (b) compound (eg, "2,4-D" in the first line). The third, fourth, and fifth columns of Table A1 list ranges of weight ratios for rates at which the Component (a) compound is typically applied to a field-grown crop relative to Component (b) (i.e. (a ):(b)). Thus, for example, the first line of Table A1 specifically describes the combination of Component (a) (this is Compound No. 1 in Table AA) with 2,4-D typically applied in a weight ratio between 1: 192-6:1. The remaining lines of Table A1 should be interpreted in a similar way. ncccnn / i znz / B / v TABLE A1 Component (a) Ratio in Most Typical Weight Ratio Most Typical Weight Ratio (Com.

What an additive (this is savior) on crops or other desirable plants. Reducing the amount of active ingredients released into the environment while ensuring effective pest control is always desirable. The ability to use larger amounts of active ingredients to provide more effective weed control without excessive crop damage is also desirable. When synergism of herbicidal active ingredients occurs on weeds at application rates that give agronomically satisfactory levels of weed control, such combinations may be advantageous in reducing crop production cost and environmental burden. When the herbicidal active ingredient savior is present in crops, such combinations may be advantageous for increasing crop protection by reducing weed competition. Of note is a combination of a compound of the description with at least one other herbicidal active ingredient. Of particular interest is such a combination where the other herbicidal active ingredient has a different site of action from the compound of the description. In certain cases, a combination with at least one other herbicidal active ingredient that has a similar spectrum of control but a different site of action will be particularly advantageous for resistance management. Thus, a composition of the present disclosure may further comprise (in a herbicidally effective amount) at least one additional herbicidal active ingredient having a similar spectrum of control but a different site of action. Compounds of this description can also be used in combination with herbicidal protectants such as alidochlor, benoxacor, cloquintocet-mexyl, cumiluron, ciometrinil, cyprosulfonamide, daimuron, dichlormid, dicyclonon, dietholate, dimepiperate, phenchlorazole-ethyl, fenchlorim, flurazole, fluxofenim, furilazole , isoxadiphen-ethyl, mefenpyr-diethyl, mephenate, methoxyphenone naphthalic anhydride (1,8naphthalic anhydride), oxabetrinyl, / V-(aminocarbonyl)-2-methylbenzenesulfonamide, / V-(aminocarbonyl)-2fluorobenzenesulfonamide, 1-bromo-4-[ (chloromethyl)sulfonyl]benzene (BCS), 4-(dichloroacetyl)-1-oxa-4azospiro[4.5]decane (MON 4660), 2-(dichloromethyl)-2-methyl-1,3-dioxolane (MG 191), Ethyl 1,6-dihydro-1-(2methox¡phenyl)-6-oxo-2-phenyl-5-pyr¡m¡ncarboxylate, 2-hidrox¡- / V, / V-d ¡methyl-6-(trifluoromethyl)pyridine-365 carboxamide, 1 -(3,4-dimethylphenyl)-1,6-dihydro-6-oxo-2-phenyl -5-pyrimidinecarboxylate, 2,2-dichloro-1-(2,2,5trimethyl-3-oxazoldinyl)-ethanone and 2-methoxy- / V-[[4-[[ (methylam¡no)carbon¡l]am¡no]fen¡l]sulfonil]-benzamida to increase safety to certain crops. Antidote-effective amounts of the herbicidal protectants can be applied at the same time as the compounds of this disclosure, or applied as seed treatments. Therefore one aspect of the present description relates to a mixture of herbicides comprising a compound of this description and an antidote-effective amount of a herbicidal protectant. Seed treatment is particularly useful for selective weed control, because it physically restricts the antidote to crop plants. Therefore a particularly useful embodiment of the present disclosure is a method of selectively controlling the growth of unwanted vegetation in a crop comprising contacting the harvest site with a herbicidally effective amount of a compound of this disclosure wherein the Seed from which the crop is grown is treated with a protectant antidote level effective amount. Antidote-effective amounts of protectants can be readily determined by one skilled in the art through simple experimentation. Compounds of the disclosure may also be mixed with: (1) polynucleotides including but not limited to DNA, RNA, and / or chemically modified nucleotides that influence the amount of a particular target through down-regulation, interference , suppression or silencing of the genetically derived transcript that produces a herbicidal effect; or (2) polynucleotides including but not limited to DNA, RNA, and / or chemically modified nucleotides that influence the amount of a particular target through downregulation, interference, suppression, or silencing of the genetically derived transcript that produces a saving effect. The following Tests A through M demonstrate the control efficacy of representative compounds of this disclosure against representative weeds, but the weed control provided by these compounds is not limited to these species.
