[0010] More specifically, the present invention relates to compounds of Formula 1 (including all stereoisomers), an N-oxide, or a salt thereof:
[0011] The present invention also relates to fungicidal compositions comprising (a) a compound of the present invention (i.e., a compound of the present invention in a fungicidally effective amount), and (b) at least one additional component selected from the group consisting of a surfactant, a solid diluent, and a liquid diluent.
[0012] The present invention also relates to fungicidal compositions comprising (a) a compound of the present invention and (b) at least one other fungicide (eg, at least one other fungicide with a different site of action).
[0013] The present invention further relates to a method for controlling plant diseases caused by fungal plant pathogens, comprising applying to a plant or part thereof, or to a plant seed, a fungicidally effective amount of a compound of the present invention (e.g., as a composition described herein).
[0014] The present invention also relates to compositions comprising a compound of Formula 1, an N-oxide, or a salt thereof, and at least one invertebrate pest control compound or agent. DETAILED DESCRIPTION OF THE INVENTION
[0015] As used herein, the terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," "characterized by," or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitations expressly stated. For example, a composition, mixture, process, method, article, or device that includes a list of elements is not necessarily limited to only those elements and may include other elements that are not expressly listed or inherent in such composition, mixture, process, method, article, or device.
[0016] The transitional phrase "consisting of" excludes any element, step, or ingredient not specified. In the context of a claim, such excludes the inclusion of materials other than those recited, except for impurities normally associated therewith. When the phrase "consisting of" appears in a clause in the body of a claim, rather than immediately following a preamble, it limits only the elements recited in that clause; other elements are not excluded from the claim as a whole.
[0017] The transitional phrase "consisting essentially of" is used to define a composition, method, or apparatus that includes materials, steps, features, ingredients, or elements in addition to those literally disclosed, provided that these additional materials, steps, features, ingredients, or elements do not materially affect the basic and novel characteristics of the claimed invention. The term "consisting essentially of" occupies a middle ground between "comprising" and "consisting of."
[0018] Where applicants have defined an invention or portion thereof using open-ended language such as "comprising," it should be readily understood that (unless otherwise expressly stated) this description should be construed as also describing such invention using the terms "consisting essentially of" or "consisting of."
[0019] Furthermore, unless expressly stated to the contrary, "or" means an inclusive "or" and not an exclusive "or." For example, a condition A or B is satisfied by any 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).
[0020] Also, the indefinite articles "a" and "an" preceding an element or component of the invention are intended to be open-ended regarding the number of instances (i.e., occurrences) of the element or component. Thus, "a" or "an" should be read to include one or at least one, and the singular form of an element or component also includes the plural, unless the number is specifically intended to be singular.
[0021] The term "agronomic" refers to the production of agricultural crops, such as for food and fiber, and includes the growing of corn or maize, soybeans and other legumes, rice, grains (e.g., wheat, oats, barley, rye, and rice), leafy vegetables (e.g., lettuce, cabbage, and other cruciferous crops), fruiting vegetables (e.g., tomatoes, peppers, eggplant, crucifers, and cucurbits), potatoes, sweet potatoes, grapes, cotton, fruit trees (e.g., pome fruits, stone fruits, and citrus fruits), small fruits (e.g., berries and cherries), and other specialty crops (e.g., canola, sunflowers, and olives).
[0022] The term "non-agronomic" refers to uses such as, for example, crops other than horticultural crops (e.g., greenhouse plants, nursery plants, or ornamental plants not grown in fields), residential, agricultural, commercial, and industrial structures, turf (e.g., turf farms, ranches, golf courses, turf, sports fields, etc.), wood products, storage products, forestry and plant care, public health (i.e., humans) and animal health (e.g., domesticated animals, such as pets, livestock, and poultry, and non-domesticated animals, such as wildlife) uses.
[0023] The term "crop vigor" refers to the rate of growth or biomass accumulation of a crop. "Increased vigor" refers to an increase in crop growth or biomass accumulation relative to an untreated control crop. The term "crop yield" refers to the return of crop material, both in terms of quantity and quality, obtained after harvesting the crop. "Increased crop yield" refers to an increase in crop yield relative to an untreated control crop.
[0024] The term "biologically effective amount" refers to an amount of a biologically active compound (e.g., a compound of Formula 1) sufficient to produce a desired biological effect when applied to (i.e., contacted with) the fungus to be controlled or its environment, or to a plant, a seed on which the plant grows, or the locus of the plant (e.g., a growth medium), either to protect the plant from damage caused by a fungal disease or for other desired effect (e.g., increased plant vigor).
[0025] As referred to in this disclosure and claims, "plants" include members of the Plantae kingdom (especially seed plants (Spermatopsida)) in all life cycles, including, for example, young plants (e.g., germinating seeds developing into seedlings) and mature reproductive stages (e.g., plants that produce flowers and seeds). Plant parts include geotropic members that typically grow below the surface of the growing medium (e.g., soil) (e.g., roots, tubers, bulbs, and corms), as well as members that grow above the growing medium (e.g., leaves (including stems and leaves), flowers, fruits, and seeds).
[0026] As referred to herein, the term "seedling" used alone or in combination with words means a young plant developing from the embryo of a seed.
[0027] As referred to herein, the term "broadleaf" used alone or in words (e.g., broadleaf crops) refers to dicotyledons or dicotyledons, terms used to describe a group of angiosperms characterized by an embryo with two cotyledons.
[0028] As used herein, the term "alkylating agent" refers to a compound in which a carbon-containing radical is bonded through a carbon atom to a leaving group (e.g., a halide or sulfonate) that is displaceable by attachment of a nucleophile to said carbon atom. Unless otherwise specified, the term "alkylating agent" does not limit the carbon-containing radical to alkyl; examples of carbon-containing radicals in alkylating agents include, for example, R 1 Illustrative examples include a variety of carbon-bonded substituent radicals defined in terms of:
[0029] As referred to in this disclosure, the terms "fungal pathogen" and "fungal plant pathogen" include pathogens of the phyla Ascomycota, Basidiomycota, and Zygomycota, as well as fungus-like Oomycota, which are causative agents of a wide range of economically important plant diseases affecting ornamental, turf, vegetable, field, grain, and fruit crops. In the context of this disclosure, "protecting plants from disease" or "controlling plant diseases" includes preventative effects (interruption of the fungal cycle of infection, colonization, symptom development, and spore production) and / or curative effects (inhibition of colonization of plant host tissue).
[0030] As used herein, the term "mode of action" (MOA) is as defined by the Fungicide Resistance Action Committee (FRAC) and is used to distinguish fungicides according to their biochemical mode of action and resistance risk in the biosynthetic pathway of plant pathogens. Modes of action as defined by FRAC include: (A) nucleic acid synthesis, (B) mitosis and cell division, (C) respiration, (D) amino acid and protein synthesis, (E) signal transduction, (F) lipid synthesis and membrane integrity, (G) sterol biosynthesis in membranes, (H) cell wall biosynthesis, (I) melanin synthesis in cell walls, (P) induction of host plant defenses, (U) unknown mode of action, (NC) not classified, (M) chemicals with multisite contact activity, and (BM) biological agents with multiple modes of action. Each mode of action (i.e., letters A-BM) contains one or more subgroups based on individual effective target sites of action or, if the exact target site is unknown, on cross-resistance profiles within the group or in relation to other groups (e.g., A contains subgroups A1, A2, A3, and A4). Each of these subgroups (e.g., A1, A2, A3, and A4) is assigned a FRAC code (numbers and / or letters). For example, the FRAC code for subgroup A1 is 4. Further information regarding target sites and FRAC codes can be obtained, for example, from publicly available databases maintained by FRAC.
[0031] As used herein, the term "cross-resistance" refers to the phenomenon that occurs when a pathogen develops resistance to one fungicide and simultaneously becomes resistant to one or more other fungicides, which are typically, but not always, in the same chemical class, have the same target site of action, or can be detoxified by the same mechanism.
[0032] Generally, when a molecular fragment (i.e., radical) is represented by a series of atomic symbols (e.g., C, H, N, O, and S), the implicit point or points of attachment will be readily apparent to one of ordinary skill in the art. In some instances herein, the point or points of attachment may also be explicitly indicated by a hyphen ("-"), particularly when alternative points of attachment are possible. Dotted lines in rings depicted herein (e.g., the ring in Formula 1) indicate that the indicated bond may be a single or double bond.
[0033] In the above description, the term "alkyl," whether used alone or in compound words such as "haloalkyl," includes straight-chain and branched alkyls, such as methyl, ethyl, n-propyl, and i-propyl. "Alkenyl" includes straight-chain and branched alkenes, such as ethenyl, 1-propenyl, 2-propenyl, and the various butenyl and pentenyl isomers. "Alkenyl" also includes polyenes, such as 1,2-propadienyl and 2,4-pentadienyl. "Alkynyl" includes straight-chain and branched alkynes, such as ethynyl, 1-propynyl, 2-propynyl, and the various butynyl and pentynyl isomers. "Alkynyl" can also include moieties composed of multiple triple bonds (e.g., 2,5-pentadiynyl).
[0034] "Alkoxy" includes, for example, methoxy, ethoxy, n-propyloxy, i-propyloxy, and the different butoxy isomers. "Alkenyloxy" includes straight-chain and branched alkenyls bonded to and linked through an oxygen atom. Examples of "alkenyloxy" include HC=CHCHO and CHCH=CHCHO. "Alkynyloxy" includes straight-chain and branched alkynyls bonded to and linked through an oxygen atom. Examples of "alkynyloxy" include HC≡CCHO and CHC≡CCHO.
[0035] "Alkoxyalkyl" denotes alkoxy substitution on alkyl. Examples of "alkoxyalkyl" include CH3OCH2, CH3OCH2CH2, CH3CHOCH2, CH3CH2CH2OCH2, and CH3CH2CH2OCH2CH2. "Alkoxyalkoxy" denotes alkoxy substitution on another alkoxy moiety. Examples of "alkoxyalkoxy" include CH3OCHO, CH3OCH2CH2CH2O, and CH3CHOCH2OCH2O.
[0036] The term "cycloalkyl" refers to a saturated carbocyclic ring of 3 to 5 carbon atoms joined together by single bonds. Examples of "cycloalkyl" include cyclopropyl, cyclobutyl, and cyclopentyl.
[0037] The term "halogen," whether used alone or in compound words such as "haloalkyl," or in descriptions such as "alkyl substituted with halogen," includes fluorine, chlorine, bromine, or iodine. Furthermore, when used in compound words such as "haloalkyl" or in descriptions such as "alkyl substituted with halogen," the alkyl may be partially or fully substituted with halogen atoms, which may be the same or different. Examples of "haloalkyl" or "alkyl substituted with halogen" include CF, ClCH, CFCHCH, and CFCC1.
[0038] "Cyanoalkyl" refers to an alkyl group substituted with one cyano group. Examples of "cyanoalkyl" include NCCH, NCCHCH, and CHCH(CN)CH. The term "cyanoalkoxy" is defined analogously to the term "cyanoalkyl."
[0039] The total number of carbon atoms in the substituent is "C i ~C j" prefix notation, where i and j are numbers from 1 to 5. For example, C1-C3 alkyl refers to methyl through propyl; C2 alkoxyalkyl refers to CHOCH2; C3 alkoxyalkyl refers to, for example, CH3CH(OCH3), CHOCH2CH2, or CH3CHOCH2; and C4 alkoxyalkyl refers to the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms (including, for example, CH3CH2CH2OCH2 and CH3CHOCH2CH2).
[0040] The term "unsubstituted" in connection with a group such as a ring means that the group does not have any substituents at one or more bonds to the remainder of Formula 1. The term "optionally substituted" means that the number of substituents can be zero. Unless otherwise specified, an optionally substituted group may be substituted with as many optional substituents as possible, so long as the non-hydrogen substituents replace hydrogen atoms on various available carbon or nitrogen atoms. Generally, the number of optional substituents (if present) ranges from 1 to 3. As used herein, the term "optionally substituted" is used interchangeably with the phrase "substituted or unsubstituted" or the term "(un)substituted."
[0041] The number of optional substituents may be limited by expressed limits. For example, the phrase "optionally substituted with up to three substituents independently selected from halogen" means that there can be 0, 1, 2, or 3 substituents (if the number of available points of attachment permits).
[0042] The compounds may have a variable number of substituents (e.g., (R 4 ) m When substituted with any of the above substituents having a subscript indicating m (where m is 0 to 5), unless otherwise specified, the substituents are independently selected from the defined group of substituents. Various groups may optionally be present at certain positions (e.g., (R 4 ) m(where m can be 0), a hydrogen may be present at this position even if not recited in the definition of the various groups.
[0043] The naming of substituents in this disclosure uses accepted terminology that provides simplicity in accurately conveying chemical structures to those of skill in the art. For the sake of simplicity, descriptors indicating positions within structural formulas may be omitted.
[0044] The term "carbocycle" refers to a ring in which the atoms forming the backbone of the ring are selected only from carbon. Unless otherwise specified, a carbocycle can be saturated, partially unsaturated, or fully unsaturated. If a fully unsaturated carbocycle satisfies Hückel's rule, the ring is also referred to as an "aromatic ring." A "saturated carbocycle" refers to a ring having a backbone made of carbon atoms connected to each other by single bonds, and unless otherwise specified, the remaining carbon valences are occupied by hydrogen atoms.
[0045] As used herein, the term "partially unsaturated ring" or "partially unsaturated heterocycle" refers to a ring that contains unsaturated ring atoms and one or more double bonds, but is not aromatic.
[0046] The term "heterocyclic ring" or "heterocycle" refers to a ring in which at least one of the atoms forming the backbone of the ring is other than carbon. Unless otherwise specified, a heterocycle can be saturated, partially unsaturated, or fully unsaturated. If a fully unsaturated heterocycle satisfies Hückel's rule, the ring is also referred to as a "heteroaromatic ring" or "aromatic heterocyclic ring." A "saturated heterocycle" refers to a heterocycle containing only single bonds between ring members.
[0047] The compounds of the present invention can exist as one or more stereoisomers. Stereoisomers are isomers that have identical constitution but differ in the spatial arrangement of their atoms, and include enantiomers, diastereomers, cis- and trans-isomers (also called geometric isomers), and atropisomers. Atropisomers result from restricted rotation around a single bond, and the high barrier to rotation makes it possible to isolate these isomeric species. As will be appreciated by those skilled in the art, one stereoisomer may be more reactive and / or exhibit advantageous effects when enriched or separated from other stereoisomers. In addition, those skilled in the art know methods for separating, enriching, and / or selectively preparing such stereoisomers. For a comprehensive discussion of all aspects of stereoisomerism, see Ernest L. Eliel and Samuel H. Wilen, Stereochemistry of Organic Compounds, John Wiley & Sons, 1994.
[0048] The invention includes all stereoisomers, conformations and mixtures thereof in all proportions as well as isotopic forms such as deuterated compounds.
[0049] As those skilled in the art will recognize, not all nitrogen-containing heterocycles can form N-oxides because the nitrogen requires an available lone pair of electrons to be oxidized to the oxide. Those nitrogen-containing heterocycles capable of forming N-oxides will be familiar to those skilled in the art. Those skilled in the art will also be familiar with the ability of tertiary amines to form N-oxides. Synthetic methods for preparing N-oxides of heterocycles and tertiary amines are very familiar to those skilled in the art, including the oxidation of heterocycles and tertiary amines using peroxyacids 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 preparing N-oxides have been widely described and reviewed in the literature, see, for example, T. L. Gilchrist, Comprehensive Organic Synthesis, vol. 7, pp. 748-750 (S.V. Ley, Ed., Pergamon Press); M. Tisler and B. Stanovnik, 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, Advances in Hetrocyclic Chemistry, vol. 43, pp. 149-161 (A.R. Katrittzky, Ed., Academic Press); M. Tisler and B. Stanovnik, Advances in Hetrocyclic Chemistry, vol. 9, pp. 285-291 (A.R. Katrittzky and A.J. Boulton, Eds., Academic Press). Press); and GWHCheeseman and ESGWerstiuk, Advances in Hetrocyclic Chemistry, vol. 22, pp. 390-392 (ARKatritzky and AJ Boulton, Eds., Academic Press).
[0050] Those skilled in the art will recognize that salts of compounds share biological utility with their corresponding non-salt forms because, under environmental and physiological conditions, salts are in equilibrium with their corresponding non-salt forms. Therefore, a wide variety of salts of compounds of Formula 1 are useful (i.e., agronomically suitable) for controlling plant diseases caused by fungal plant pathogens. Salts of compounds of Formula 1 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, propynoic acid, salicylic acid, tartaric acid, 4-toluenesulfonic acid, or valeric acid. When compounds of Formula 1 contain an acidic residue, such as a carboxylic acid, salts also include those formed with organic or inorganic bases, such as pyridine, triethylamine, or ammonia, or amides, hydrides, hydroxides, or carbonates of sodium, potassium, lithium, calcium, magnesium, or barium. Thus, the present invention includes compounds selected from Formula 1, their N-oxides and agriculturally suitable salts and solvates.
[0051] Compounds selected from Formula 1, their stereoisomers, tautomers, N-oxides, and salts typically exist in more than one form; therefore, Formula 1 includes all crystalline and amorphous forms of the compounds represented by Formula 1. Amorphous forms include solid embodiments, such as waxes and rubbers, as well as liquid embodiments, such as solutions and melts. Crystalline forms include embodiments that exhibit a substantially single crystal type and embodiments that exhibit a mixture of polymorphs (i.e., multiple crystalline types). The term "polymorph" refers to a particular crystalline form of a compound that can crystallize in various crystalline forms, which have different molecular arrangements and / or conformations within the crystal lattice. Polymorphs can have the same chemical composition, but they can also differ in composition due to the presence or absence of co-crystallized water or other molecules that can be weakly or strongly bound in the lattice. Polymorphs may differ in chemical, physical, and biological properties, such as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspendability, dissolution rate, and biological availability. As will be appreciated by those skilled in the art, polymorphs of the compound of Formula 1 may exhibit advantageous effects (e.g., compatibility in preparing useful formulations, improved biological performance) compared to other polymorphs of the same compound of Formula 1 or mixtures of multiple polymorphs. Preparation and isolation of specific polymorphs of the compound of Formula 1 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 polymorphism, see R. Hilfiker, Ed., Polymorphism in the Pharmaceutical Industry, Wiley-VCH, Weinheim, 2006.

Of note are embodiments of such methods that comprise applying a fungicidally effective amount of a compound corresponding to any of the compound embodiments described above. Of particular note are embodiments in which the compound is applied as a composition of the invention.
[0168] Compounds of Formula 1 may be prepared using one or more of the following methods and variations illustrated in Schemes 1-10. 1 , R 2 , R 3 , R 4 , R 5The definitions of m, n, and p are as defined above in the Summary of the Invention unless otherwise specified. The compounds of Formulas 1a, 1b, 1c, 1d, and 1e are various subsets of the compounds of Formula 1, and all substituents of Formulas 1a, 1b, 1c, 1d, and 1e are as defined above for Formula 1 unless otherwise specified.
[0169] As shown in Scheme 1, a compound of formula 1 can be reacted with a compound of formula R 1 The compound of formula 2 can be prepared by alkylation of a compound of formula 2 with a compound of formula -Lg, where Lg is a leaving group such as a halogen (e.g., Cl, Br) or a sulfonate (e.g., methanesulfonate). Particularly useful alkylating agents include, but are not limited to, alkyl halides and the like (e.g., iodoethane, allyl bromide, propargyl chloride), and alkyl sulfates (e.g., dimethyl sulfate). Typically, this reaction is carried out in the presence of a base (e.g., sodium hydride, potassium tert-butoxide, sodium ethoxide, or potassium carbonate) and in a solvent compatible with the base (e.g., dimethyl sulfoxide, N,N-dimethylformamide, tetrahydrofuran, acetonitrile, or ethanol). This reaction can be carried out at a temperature ranging from about 0 to 100°C. For reaction conditions, see Journal of Medicinal Chemistry 1980, 23(12), 1398-1405. Similarly, this Example 14, Step E, illustrates the method of Scheme 1. [ka]
[0170] As shown in Scheme 2, a compound of Formula 1a (i.e., Formula 1 in which the dotted line represents a bond and p is 0) can be prepared by oxidative dehydrogenation of the corresponding compound of Formula 1b (i.e., Formula 1 in which the dotted line is absent and p is 1). A wide range of oxidizing agents and reaction conditions are suitable for the method of Scheme 2. For example, oxygen can be used as an oxidizing agent in the presence of a copper(II) salt such as copper(II) chloride and a solvent such as acetonitrile (see, e.g., Synthetic Communications 2000, 30(1), 1-7). Copper(II) acetate can also be used in the presence of a base such as sodium carbonate and a solvent such as toluene at temperatures from about ambient temperature to the boiling point of the solvent (see, e.g., European Journal of Organic Chemistry 2013, 2013(27), 6130-6136). Compounds of Formula 1b can also be treated with elemental halogens (e.g., Cl, Br, I) in a solvent such as acetic acid or dimethyl sulfoxide to give compounds of Formula 1a. For relevant references using dihalides, see, for example, Arzneimittel Forschung 2005, 55(6), 318-325 and Chinese Chemical Letters 2011, 22(12), 1435-1438. Alternatively, activated manganese dioxide can be used as an oxidizing agent in a solvent (e.g., dichloromethane, dichloroethane, toluene, or chlorobenzene) at temperatures from about ambient temperature to the boiling point of the solvent. This reaction can also be carried out at temperatures above the boiling point of the solvent using a pressurized vessel (optionally in conjunction with a microwave reactor). The method of Scheme 2 using manganese dioxide is described in this Example 2. [ka]
[0171] One skilled in the art can prepare intermediate compounds of formula 2 where the dotted line represents a bond and p is 0 by analogy with the oxidation method described in Scheme 2 above (where R 1 will recognize that the 'H' has been replaced by 'H'.
[0172] As shown in Scheme 3, compounds of Formula 1b, where W is O, can be prepared by cyclization of an α-keto acid or ester of Formula 3 with an appropriately substituted hydrazine of Formula 4. This reaction can be carried out in a variety of solvents, such as ethanol, 1-butanol, tetrahydrofuran, 1,4-dioxane, heptane, or toluene. Optionally, an acid or base catalyst can be added to the reaction mixture to facilitate the removal of water. Particularly useful catalysts include bases such as pyridine, sodium acetate, or triethylamine; or acids such as acetic acid, oxalic acid, or hydrochloric acid. Alternatively, an acid salt of the hydrazine of Formula 4 can be used in combination with a base such as an alkali metal hydroxide or carbonate (preferably sodium acetate). In some cases, it may be advantageous to carry out the initial condensation of Formulas 3 and 4 in an alcoholic solvent (e.g., ethanol), concentrate the reaction mixture, and then add a solvent such as toluene or chlorobenzene, followed by heating under azeotropic conditions, optionally in the presence of an acid catalyst such as sulfuric acid or p-toluenesulfonic acid. This type of cyclization reaction is well described in the chemical literature; see, for example, Archives of Pharmaceutical Research 2010, 33(1), 25-46; Journal of Medicinal Chemistry 2001, 44(16), 2511-2522; Monatshefte für Chemie 2004, 135(12), 1519-1527; and Indo Global Journal of Pharmaceutical Sciences 2016, 6(2), 65-71. This Example 1, Step D, involves the reaction of R 1 Scheme 3 illustrates a method for preparing compounds of formula 1b where is methyl, using methylhydrazine. [ka]
[0173] Intermediate compounds of formula 2 where the dotted line is absent and p is 1 can be prepared similarly to the method described in Scheme 3, using hydrazine or hydrazine hydrate in place of compounds of formula 4.
[0174] As shown in Scheme 4, R a α-Ketoesters of formula 3, where Lg is alkyl, can be prepared by alkylation of diaryl ketones of formula 5 with compounds of formula 6, where Lg is a leaving group such as a halogen (e.g., Cl, Br) or a sulfonate (e.g., methanesulfonate) in the presence of a base (e.g., sodium hydride, sodium acetate, potassium tert-butoxide, lithium diisopropylamide, or lithium bis(trimethylsilyl)amide). This reaction is typically carried out in a suitable solvent (e.g., dimethyl sulfoxide, N,N-dimethylformamide, tetrahydrofuran, 2-methyl-2-propanol, or toluene) selected for its compatibility with the base. The use and selection of an appropriate solvent will be apparent to those skilled in the art of chemical synthesis. For a representative procedure for the alkylation method of Scheme 4 using lithium diisopropylamide in tetrahydrofuran, see Journal of Medicinal Chemistry 2006, 49(2), 456-458. Similarly, the method of Scheme 4 using sodium hydride in a mixture of dimethylsulfoxide and tetrahydrofuran is described in Example 1, Step B. [ka]
[0175] R a is hydrogen, by means known to those skilled in the art, to form a carboxylic acid of formula 3, a This Example 1, Step C illustrates the hydrolysis of the ethyl ester of formula 3 to the corresponding carboxylic acid.
[0176] Alternatively, as shown in Scheme 5, R 3Compounds of formula 3, wherein is H, can be prepared by reacting compounds of formula 7 with benzaldehydes of formula 8 in the presence of a cyanide salt such as sodium cyanide. For reaction conditions, see, for example, Chemische Berichte 1976, 109(2), 541-545.
[0177] Compounds of formula 7 and 8 are commercially available and can be prepared by methods described in the chemical literature. [ka]
[0178] General methods useful for preparing diaryl ketones of Formula 5 are known in the art; see, for example, Chemical Research in Toxicology 2011, 24(11), 1853-1861; and Royal Society of Chemistry 2017, 7, 11367-11372; and references therein. Of particular note is the method illustrated in Scheme 6 below, which involves the reaction of a phenylacetic acid of Formula 9 with a benzoic acid ester of Formula 10. Typically, this reaction is carried out with the aid of a base and in the presence of an inert organic solvent, such as sodium hydride, lithium diisopropylamide, or lithium bis(trimethylsilyl)amide (LiHMDS) in a solvent such as benzene, toluene, N,N-dimethylformamide, or tetrahydrofuran. The product can be isolated by adjusting the pH to about 1-7, followed by filtration or extraction, optionally after removal of the organic solvent. This Example 1, Step A, illustrates the method of Scheme 6. [ka]
[0179] Formula 1c (i.e., the dotted line represents a bond, p is 0, and R 2Compounds of formula 1 (wherein R is cyano and W is O) can be synthesized as outlined in Scheme 7. In a first step, compounds of formula 12 are prepared by the reaction of compounds of formula 11 with hydrazine or hydrazine hydrate. This reaction is typically carried out in a solvent such as ethanol or methanol, following general procedures known in the art. Reaction of compounds of formula 12 with cyanoacetate salts of formula 13 in the presence of a base (e.g., sodium hydride or potassium tert-butoxide) and a solvent (e.g., ethanol) gives compounds of formula 2a (i.e., where the dotted line represents a bond, p is 0, and R is O). 2 Compounds of formula 2) where OH is cyano and W is O are obtained. The intermediate of formula 2a can be alkylated to give compounds of formula 1c, similar to the method of Scheme 1. For references, see, for example, Journal of Medicinal Chemistry 1980, 23(12), 1398-1405. Similarly, the method of Scheme 7 is illustrated in this Example 14, Steps C, D, and E. [ka]
[0180] Compounds of formula 11 are commercially available and can be prepared according to common methods known to those skilled in the art. For example, as shown in Scheme 8, catalytic oxidation of compounds of formula 14 can be achieved with oxygen as an oxidant in the presence of a catalyst such as copper(II) oxide and iodine, or 1,4-diazabicyclo[2.2.2]octane (DABCO). This reaction is typically carried out in a solvent such as dimethyl sulfoxide. For reaction conditions, see, for example, Synthesis 2011, 3, 387-396; Synthesis 2013, 45(12), 1701-1707; and Journal of the American Chemical Society 2016, 138(3), 810-813. Similarly, this Example 14, Step B, illustrates the method of Scheme 8. [ka]
[0181] Those skilled in the art will recognize that for some compounds of formula 1, the substituent R attached to the phenyl ring 4 and / or R 5 It will be appreciated that R may be more conveniently incorporated after formation of the central pyridazinone ring to which it is attached. For example, as shown in Scheme 9, compounds of Formula 1 may be aromatically nitrated to form R 4 or R 5 is nitro. Nitration can be accomplished according to known methods, for example, by treating a compound of Formula 1 with nitric acid (or a derivative thereof) or a mixture of nitric acid and an acid catalyst (e.g., sulfuric acid or acetic anhydride). Those skilled in the art will recognize certain functional groups (i.e., other R attached to the phenyl ring) that may be present in a compound of Formula 1. 4 and / or R 5 It will be recognized that the substituents (such as methyl, ... 5 The method of Scheme 9 for adding a nitro group is illustrated. [ka]
[0182] Similar to the method of Scheme 9, compounds of formula 1 can be treated with a halogenating agent to afford R 4 and / or R 5Compounds of Formula 1 can be obtained in which at least one of the groups is a halogen. Various halogenating agents known in the art can be used, such as N-halosuccinimides (e.g., NBS, NCS, NIS), elemental halogens (e.g., Cl, Br, I), and sulfuryl chloride. Typically, this reaction is carried out in a suitable solvent, such as N,N-dimethylformamide, acetonitrile, dichloromethane, benzene, chlorobenzene, or tetrahydrofuran. Optionally, an organic base, such as triethylamine, pyridine, or N,N-dimethylaniline, can be added. Typical reaction temperatures range from about room temperature to 150°C. See Examples 6 and 7 for specific reaction conditions.
[0183] R 2 Compounds of formula 1, etc., where R is halogen or alkyl can be prepared by converting R 2 For example, as shown in Scheme 10, first prepare a compound of formula 1d (i.e., where the dotted line represents a bond, p is 0, and R 2 Compounds of formula 1) where R is H can be treated with an organometallic agent, such as an alkyllithium base (e.g., n-butyllithium, s-butyllithium, lithium diisopropylamide, or lithium tetramethylpiperidide), or a Grignard reagent (e.g., tetramethylpiperidinyl magnesium chloride), in a solvent such as toluene, ethyl ether, tetrahydrofuran, or dimethoxymethane at a temperature ranging from about −78° C. to ambient temperature. Subsequent treatment with a halogenating or alkylating agent affords the formation of R 2 is halogen or alkyl to obtain a compound of formula 1e. For alkylation reaction conditions, see, for example, Journal of Medicinal Chemistry 1980, 23(12), 1398-1405. For halogenation reaction conditions, see Examples 4, 8, and 11. [ka]
[0184] The methods of Schemes 9 and 10 are just two examples of techniques for adding or modifying existing substituents in compounds of Formula 1. Those skilled in the art will recognize that compounds of Formula 1 can also be subjected to numerous other electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to provide other functionalized compounds of Formula 1. For example, as illustrated in this Example 12, R 2 Using a compound of formula 1 where R is a halogen, 2 Compounds of Formula 1 in which is alkyl can be prepared. Compounds of Formula 1, or intermediates for preparing them, may contain aromatic nitro groups, which can be reduced to amino groups and then converted to various halides via reactions well known to those skilled in the art (e.g., the Sandmeyer reaction). Similar known reactions allow aromatic halides, such as bromides or iodides, prepared by the Sandmeyer reaction to be reacted with alcohols under copper-catalyzed conditions, such as the Ullmann reaction or known modifications thereof, to give compounds of Formula 1 containing alkoxy substituents. Furthermore, some halogen groups, such as fluorine or chlorine, can be displaced with alcohols under basic conditions to give compounds of Formula 1 containing the corresponding alkoxy substituents. Compounds of Formula 1, or their precursors containing halides, preferably bromides or iodides, are particularly useful as intermediates for transition-metal-catalyzed cross-coupling reactions to prepare compounds of Formula 1. These types of reactions are well described in the literature, see, for example, Tsuji, "Transition Metal Reagents and Catalysts: Innovations in Organic Synthesis", John Wiley and Sons, Chichester, 2002; Tsuji, "Palladium in Organic Synthesis", Springer, 2005; and Miyaura and Buchwald, "Cross Coupling Reactions: A Practical Guide, 2002"; and references cited therein.
[0185] Compounds of Formula 1 where W is O and the intermediates described in the methods above can be converted to the corresponding thiolates where W is S using a variety of standard thiating reagents, such as phosphorus pentasulfide or 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide (Lawson's reagent). Reactions of this type are known, see for example Heterocycles 1995, 40, 271-278; Journal of Medicinal Chemistry 2008, 51, 8124-8134; Journal of Medicinal Chemistry 1990, 33, 2697-706; Synthesis 1989, (5), 396-3977; J. Chem. Soc., Perkin Trans. 1, 1988, 1663-1668; Tetrahedron 1988 44, 3025-3036; and Journal of Organic Chemistry 1988 53(6), 1323-1326. See also, for example, for pyridazinones, Journal of Heterocyclic Chemistry 1988, 25(6), 1719-23; and Phosphorus, Sulfur and Silicon and the Related Elements 2000, 156, 213-223.
[0186] It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula 1 may be incompatible with certain functional groups present in the intermediates. In these cases, the incorporation of protection / deprotection sequences or functional group interconversions into the synthesis may be helpful to obtain the desired products. The use and selection of protecting groups will be apparent to those skilled in chemical synthesis (see, for example, Greene, TW; Wuts, PGM Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). Those skilled in the art will recognize that, in some cases, after the introduction of the reagents depicted in the individual schemes, additional routine synthetic steps not described in detail may be required to complete the synthesis of compounds of Formula 1. Those skilled in the art will also recognize that, to prepare compounds of Formula 1, it may be necessary to perform combinations of the steps described in the above schemes in an order other than that implied by the specific order presented.

The following examples are therefore merely illustrative and should not be construed as limiting the present disclosure in any way.

[0220] Compounding / Usefulness The compounds of formula 1 of the present invention (including their N-oxides and salts) may be used as fungicidal active ingredients in compositions (i.e., formulations), generally with at least one additional ingredient selected from the group consisting of surfactants, solid diluents, and liquid diluents, which functions as a carrier. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, the mode of application, and environmental factors such as soil type, moisture, and temperature.
[0221] Useful formulations include liquid and solid compositions. Liquid compositions include solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions, oil-in-water emulsions, flowable concentrates, and / or suspoemulsions), which can optionally be thickened to form gels. Common types of aqueous liquid compositions are soluble concentrates, suspension concentrates, capsule suspensions, concentrated emulsions, microemulsions, oil-in-water emulsions, flowable concentrates, and suspoemulsions. Common types of non-aqueous liquid compositions are emulsifiable concentrates, microemulsifiable concentrates, dispersible concentrates, and oil dispersions.
[0222] Common types of solid compositions are dusts, powders, granules, pellets, pellets, pastilles, tablets, filled films (including seed coatings), etc., which can be water-dispersible ("wettable") or water-soluble. Films and coatings formed from film-forming solutions or flowable suspensions are particularly useful for seed treatments. Active ingredients can be (micro)encapsulated and further formed into suspensions or solid formulations; alternatively, whole formulations of active ingredients can be encapsulated (or "overcoated"). Encapsulation can control or slow the release of the active ingredient. Emulsifiable granules combine the advantages of both emulsifiable concentrate and dry granular formulations. High-strength compositions are primarily used as intermediates for further formulations.
[0223] Sprayable formulations are typically diluted in a suitable vehicle before spraying. Such liquid and solid formulations are formulated and readily diluted in a spray vehicle, usually water, but sometimes another suitable vehicle such as an aromatic or paraffinic hydrocarbon or vegetable oil. Application rates can range from about one to several thousand liters per hectare, but are more typically in the range of about 10 to several hundred liters per hectare. Sprayable formulations can be tank-mixed with water or another suitable vehicle for foliar treatment by aerial or ground application, or for application to the plant's growing medium. Liquid and dry formulations can be metered directly into drip irrigation systems or into furrows during planting. Liquid and solid formulations can be applied onto seeds of crops and other desirable vegetation as pre-plant seed treatments to protect developing roots and other underground plant parts and / or foliage by systemic absorption.
[0224] The formulations will typically contain effective amounts of the active ingredient, diluent and surfactant within the approximate ranges set forth below, which add up to 100 weight percent.
[0225] [Table 1]
[0226] Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite, and kaolin, gypsum, cellulose, titanium dioxide, zinc oxide, starch, dextrin, sugars (e.g., lactose, saccharose), silica, talc, mica, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Typical solid diluents are described in Watkins et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey.

Liquid diluents also include alkylated (e.g., methylated, ethylated, butylated) fatty acids, which may be obtained by hydrolysis of glycerol esters from plant and animal sources, or which can be purified by distillation. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950.
[0228] The solid and liquid compositions of the present invention often contain one or more surfactants. When added to a liquid, surfactants (also known as "surface-active agents") generally modify, and in most cases lower, the surface tension of the liquid. Depending on the nature of the hydrophilic and lipophilic groups in the surfactant molecule, surfactants can be useful as wetting agents, dispersing agents, emulsifying agents, or antifoaming agents.
[0229] Surfactants can be classified as nonionic, anionic, or cationic surfactants. Nonionic surfactants useful in the present compositions include alcohol alkoxylates, such as those based on natural and synthetic alcohols (which may be branched or linear) and those prepared from alcohols and ethylene oxide, propylene oxide, butylene oxide, or mixtures thereof; amine ethoxylates, alkanolamides, and ethoxylated alkanolamides; alkoxylated triglycerides, such as ethoxylated soybean oil, castor oil, and rapeseed oil; alkylphenol alkoxylates, such as octylphenol ethoxylate, nonylphenol ethoxylate, dinonylphenol ethoxylate, and dodecylphenol ethoxylate (prepared from phenols and ethylene oxide, propylene oxide, butylene oxide, or mixtures thereof); block polymers prepared from ethylene oxide or propylene oxide and reverse block polymers in which the end blocks are prepared from propylene oxide; ethoxylated triglycerides, such as ethoxylated soybean oil, castor oil, and rapeseed oil; ... ethoxylated fatty acids; ethoxylated fatty acid esters and oils; ethoxylated methyl esters; ethoxylated tristyrylphenols (including those made from ethylene oxide, propylene oxide, butylene oxide, or mixtures thereof); fatty acid esters, glycerol esters, lanolin-based derivatives, polyethoxylate esters such as polyethoxylated sorbitan fatty acid esters, polyethoxylated sorbitol fatty acid esters, and polyethoxylated glycerol fatty acid esters; other sorbitan derivatives such as sorbitan esters; polymeric surfactants such as random copolymers, block copolymers, alkyd PEG (polyethylene glycol) resins, graft or comb polymers, and star polymers; polyethylene glycol (PEG); polyethylene glycol fatty acid esters; silicone-based surfactants; and sugar derivatives such as sucrose esters, alkyl polyglycosides, and alkyl polysaccharides.
[0230] Useful anionic surfactants include alkylaryl sulfonic acids and their salts; carboxylated alcohol or alkylphenol ethoxylates; diphenyl sulfonate derivatives; lignin and lignin derivatives such as lignosulfonates; maleic or succinic acid or their anhydrides; olefin sulfonates; phosphate esters such as phosphate esters of alcohol alkoxylates, phosphate esters of alkylphenol alkoxylates, and phosphate esters of styrylphenol ethoxylates; protein-based surfactants; sarcosine derivatives; styrylphenol ether sulfates; sulfates of alcohols; sulfates of ethoxylated alcohols; sulfonates of amines and amides such as N,N-alkyl taurates; sulfonates of benzene, cumene, toluene, xylene, and dodecyl and tridecyl benzene; sulfonates of condensed naphthalenes; sulfonates of naphthalene and alkyl naphthalenes; sulfonates of fractionated petroleum; sulfosuccinates; and sulfosuccinates and their derivatives such as dialkyl sulfosuccinate salts.
[0231] Useful cationic surfactants include, but are not limited to, amides and ethoxylated amides; amines such as N-alkylpropanediamines, tripropylenetriamines, and dipropylenetetraamines, and ethoxylated amines, ethoxylated diamines, and propoxylated amines (made from amines and ethylene oxide, propylene oxide, butylene oxide, or mixtures thereof); amine salts and diamine salts such as amine acetates; quaternary ammonium salts such as quaternary salts, ethoxylated quaternary salts, and diquaternized salts; and amine oxides such as alkyldimethylamine oxides and bis-(2-hydroxyethyl)-alkylamine oxides.
[0232] Mixtures of nonionic and anionic surfactants or mixtures of nonionic and cationic surfactants are also useful in the present compositions. Nonionic, anionic, and cationic surfactants and their recommended uses are disclosed in various 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.
[0233] The compositions of the present invention may also contain formulation aids and additives known to those skilled in the art as formulation aids (some of which may also function as solid diluents, liquid diluents, or surfactants). Such formulation aids and additives may control pH (buffers), foaming during processing (antifoaming agents such as polyorganosiloxanes), active ingredient settling (suspending agents), viscosity (thixotropic thickeners), microbial growth in the container (antimicrobial agents), product freezing (antifreeze agents), color (dye / pigment dispersions), leaching (film formers or stickers), evaporation (evaporation inhibitors), and other formulation attributes. Film formers include, for example, polyvinyl acetate, polyvinyl acetate copolymers, polyvinylpyrrolidone-vinyl acetate copolymers, polyvinyl alcohol, polyvinyl alcohol copolymers, and waxes. Examples of formulation aids and additives include those listed in McCutcheon's Volume 2: Functional Materials, annual International and North American editions, published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; and PCT Publication No. WO 03 / 024222.
[0234] The compound of Formula 1 and any other active ingredients are typically incorporated into the present compositions by dissolving the active ingredients in a solvent or by grinding in a liquid or dry diluent. Solutions, such as 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 water-miscible, an emulsifier is typically added to emulsify the active-containing solvent upon dilution with water. Active ingredient slurries with particle sizes of 2,000 μm or less can be wet-milled using a media mill to obtain particles with an average diameter below 3 μm. Aqueous slurries can be made into finished suspension concentrates (see, e.g., U.S. Pat. No. 3,060,084) or further processed by spray drying to form water-dispersible granules. Dry formulations usually require dry milling, which produces an average particle size in the 2-10 μm range. Fines and powders can be prepared by blending and grinding, usually (such as with a hammer mill or fluid energy mill). Granules and pellets can be prepared by spraying the active material onto a preformed granular carrier or by agglomeration techniques. See Browning, "Agglomeration," Chemical Engineering, December 4, 1967, pp. 147-48; Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pp. 8-57 and subsequent publications; and WO 91 / 13546. Pellets can be prepared as described in U.S. Pat. No. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. Pat. No. 4,144,050, U.S. Pat. No. 3,920,442, and German Patent No. 3,246,493. Tablets can be prepared as taught in US Pat. Nos. 5,180,587, 5,232,701, and 5,208,030.Films can be prepared as taught in British Patent No. 2,095,558 and US Pat. No. 3,299,566.
[0235] One embodiment of the present invention relates to a method for controlling fungal pathogens, comprising diluting a fungicidal composition of the present invention (a compound of Formula 1 formulated with a surfactant, a solid diluent, and a liquid diluent, or a formulated mixture of a compound of Formula 1 and at least one other fungicide) with water, and optionally adding an adjuvant to form a diluted composition, and contacting the fungal pathogen or its environment with an effective amount of the diluted composition.
[0236] Although a spray composition formed by diluting a sufficient concentration of the fungicidal composition with water may provide sufficient efficacy for the control of fungal pathogens, separately formulated adjuvant products may also be added to the spray tank mixture. These additional adjuvants, commonly known as "spray adjuvants" or "tank-mix adjuvants," include any substance mixed in the spray tank to improve pesticide performance or modify the physical properties of the spray mixture. Adjuvants may be anionic or nonionic surfactants, emulsifiers, petroleum-based crop oils, crop-derived seed oils, acidifiers, buffers, thickeners, or antifoaming agents. Adjuvants are used to enhance efficacy (e.g., bioavailability, adhesion, penetration, uniformity of coverage, and durability of protection) or to minimize or eliminate spray application problems associated with incompatibility, foaming, drift, evaporation, vaporization, and decomposition. To achieve optimal performance, adjuvants are selected with respect to the characteristics of the active ingredient, formulation, and target (e.g., crop, pest).
[0237] The amount of adjuvant added to the spray mixture generally ranges from about 0.1 to 2.5% by volume. The application rate of adjuvant added to the spray mixture is typically about 1 to 5 L per hectare. Representative examples of spray adjuvants include: Adigor® (Syngenta), a 47% methylated rapeseed oil in a liquid hydrocarbon; Silwet® (Helena Chemical Company), a polyalkylene oxide-modified heptamethyltrisiloxane; and Assist® (BASF), a 17% surfactant blend in 83% paraffin-based mineral oil.
[0238] One method of seed treatment involves spraying or dusting the seeds with a compound of the present invention (i.e., the compound as a formulated composition) before sowing. Compositions formulated for seed treatment generally contain a film former or adhesive. Thus, a seed coating composition of the present invention typically contains a biologically effective amount of a compound of Formula 1 and a film former or adhesive. Seeds can be coated by spraying a flowable suspension concentrate directly into a rolling bed of seeds and then allowing the seeds to dry. Alternatively, other types of formulations (e.g., wet powders, solutions, suspoemulsions, emulsifiable concentrates, and emulsions in water) can be sprayed onto the seeds. This process is particularly useful when applying a film coating onto the seeds. A variety of coating machines and processes are available to those skilled in the art. Suitable processes include those listed in P. Kosters et al., Seed Treatment: Progress and Prospects, 1994, BCPC Monograph No. 57, and the references cited therein.

[0253] Water-soluble and water-dispersible formulations are typically applied after dilution with water to form an aqueous composition. Aqueous compositions for direct application to plants or parts thereof (e.g., spray tank compositions) typically contain at least about 1 ppm or more (e.g., 1 ppm to 100 ppm) of a compound of the invention.

The compounds and / or compositions of the present invention provide control of diseases caused by a wide range of fungal plant pathogens in the phyla Ascomycota, Basidiomycota, Zygomycota, and Oomycota. This is effective in controlling a wide range of plant diseases, particularly foliar pathogens of ornamental plants, turf, vegetables, field, cereal, and fruit crops. These pathogens include, but are not limited to, those listed in Table 1-1. In the case of Ascomycota and Basidiomycota, both the sexual / telomorph / telomorph names and the asexual / asexual / deuteromorph names (in parentheses) are listed when known. Synonymous names of pathogens are indicated with an equal sign.

By controlling harmful microorganisms, the compounds of the present invention are useful for improving (i.e., increasing) the ratio of beneficial to harmful microorganisms in contact with crop plants or their vegetative propagules (e.g., seeds, corms, bulbs, tubers, cuttings) or the agronomic environment of crop plants or their vegetative propagules.
[0260] The compounds of the present invention are useful in treating whole plants, plant parts, and seeds. Plant and seed varieties and cultivars can be obtained by conventional breeding and propagation methods, or by genetic engineering methods. Genetically modified plants or seeds (transgenic plants or seeds) are those in which a heterologous gene (transgene) has been stably integrated into the genome of the plant or seed. A transgene defined by a specific location in the plant genome is called a transformation or transgenic event.
[0261] Genetically modified plant cultivars that can be treated according to the present invention include those that exhibit tolerance to one or more biotic stresses (pests, such as nematodes, insects, mites, fungi, etc.) or abiotic stresses (drought, low temperatures, soil salinity, etc.), or that contain other desirable traits. Plants can be genetically modified to exhibit traits such as herbicide tolerance, insect resistance, modified oil profile, or drought tolerance.
[0262] Treatment of genetically modified plants and seeds with the compounds of the invention can result in superadditive or enhanced effects, such as reduced application rates, broadened spectrum of activity, increased tolerance to biotic / abiotic stresses, or enhanced storage stability, relative to what would be expected from the merely additive effects of applying the compounds of the invention to genetically modified plants and seeds.
[0263] The compounds of the present invention are useful in seed treatments to protect seeds from plant diseases. In the context of this disclosure and claims, treating seeds means contacting the seeds with a biologically effective amount of a compound of the present invention (typically formulated as a composition of the present invention). This seed treatment protects the seeds from soil-borne disease pathogens and may also generally protect the roots and other plant parts of the seedlings that grow from the germinating seeds and are in contact with the soil. This plant treatment may also protect the leaves through translocation of the compound of the present invention or through the release of another active ingredient within the growing plant. Seed treatments can be applied to all types of seeds (e.g., those from which plants genetically transformed to express specialized traits are grown). Representative examples include those that express proteins toxic to invertebrate pests (e.g., Bacillus thuringiensis toxins) or those that express herbicide resistance (e.g., glyphosate acetyltransferase, which confers tolerance to glyphosate). Seed treatments with the compounds of the present invention may also increase the vigor of plants growing from the seeds.
[0264] The compounds of the present invention and compositions thereof, both alone and in combination with other fungicides, nematicides, and insecticides, are particularly useful in seed treatment of crops including, but not limited to, maize or corn, soybeans, cotton, cereals (e.g., wheat, oats, barley, rye, and rice), potatoes, vegetables, and oilseed rape.
[0265] Furthermore, the compounds of the present invention are useful for treating postharvest diseases of fruits and vegetables caused by fungi, oomycetes, and bacteria. This infection can occur before, during, and after harvest. For example, infection can occur before harvest and then remain dormant until some point during ripening (e.g., when the host begins tissue changes that allow infection to progress or conditions that favor disease development); similarly, infection can occur through surface wounds caused by mechanical or insect damage. In this regard, the compounds of the present invention can reduce losses (i.e., losses in quantity and quality) due to postharvest diseases that can occur at any time from harvest to consumption. Treatment of postharvest diseases with the compounds of the present invention can allow perishable edible plant parts (e.g., fruits, seeds, leaves, stems, bulbs, tubers) to be stored refrigerated or unrefrigerated after harvest, maintain their edibility, and extend the period without significant or harmful decomposition or contamination by fungi or other microorganisms. Pre- or post-harvest treatment of edible plant parts with the compounds of the invention may also reduce the formation of toxic metabolites of fungi or other microorganisms (eg, mycotoxins such as aflatoxins).
[0266] Control of plant diseases can usually be achieved by applying an effective amount of the compound of the present invention to the part of the plant to be protected, such as the roots, stems, leaves, fruits, seeds, tubers, or bulbs, or to the medium (soil or sand) in which the plant to be protected is growing, either before or after infection. The compound can also be applied to seeds to protect the seeds and the seedlings that grow from the seeds. The compound can also be applied via irrigation water to treat plants. Control of post-harvest pathogens that infect agricultural products before harvest is typically achieved by field application of the compound of the present invention; when infection occurs after harvest, the compound can be applied to the harvested crop as a dip, spray, fumigant, treatment wrap, and box liner.
[0267] The compounds may also be applied using unmanned aerial vehicles (UAVs) to spray the compositions disclosed herein over a cropped area. In some embodiments, the cropped area is a crop-containing area. In some embodiments, the crop is selected from monocotyledonous or dicotyledonous plants. In some embodiments, the crop is selected from rice, corn, barley, soybean, wheat, vegetables, tobacco, tea plants, fruit trees, and sugarcane. In some embodiments, the compositions disclosed herein are formulated for spraying at ultra-low volumes. Products applied by drones may use water or oil as the spray carrier. Typical spray volumes (including product) used for drone application worldwide are 5.0 liters / ha to 100 liters / ha (approximately 0.5 to 10 gpa). This includes the ultra-low spray volume (ULV) to low spray volume (LV) range. Although not common, there may be situations where spray volumes as low as 1.0 liter / ha (0.1 gpa) may be used.
[0268] The application rate of the compound (i.e., a fungicidally effective amount) may be affected by factors such as the plant disease to be controlled, the plant species to be protected, the population structure of the pathogen to be controlled, ambient humidity and temperature, and should be determined under actual use conditions. Those skilled in the art can easily determine, through simple experimentation, the fungicidally effective amount required for the desired level of plant disease control. Foliage can usually be protected when treated at rates of less than about 1 g / ha to about 5,000 g / ha of active agent. Seeds and seedlings can usually be protected when treated at rates of about 0.001 g (more typically about 0.1 g) to about 10 g per kilogram of seed.
[0269] The compounds of the present invention may also be useful for enhancing the vigor of crops. The method involves contacting a crop (e.g., foliage, flowers, fruits, or roots) or a seed from which the crop grows with a compound of Formula 1 in an amount sufficient to achieve the desired plant vigor effect (i.e., a biologically effective amount). Typically, the compound of Formula 1 is applied in a formulated composition. While the compound of Formula 1 is often applied directly to the crop or its seeds, it can also be applied to the locus of the crop, i.e., to the crop's environment, particularly to a portion of the environment sufficiently close to the crop to allow the compound of Formula 1 to migrate thereto. A suitable locus for the method most commonly includes the growth medium (i.e., the medium that provides nutrients to the plant), typically the soil in which the plant grows. Treating a crop to enhance crop vigor therefore involves contacting the crop, the seed from which the crop grows, or the locus of the crop with a biologically effective amount of a compound of Formula 1.
[0270] Increased crop vigor can result in one or more of the following observed effects: (a) optimal cropping system as evidenced by superior seed germination, crop emergence, and crop stand; (b) increased crop growth as evidenced by fast and robust leaf growth (e.g., as measured by leaf area index), plant height, number of shoots (e.g., for rice), root mass, and total dry weight of the plant mass of the crop; (c) improved crop yield as evidenced by time to flowering, duration of flowering, number of flowers, total biomass accumulation (i.e., yield), and / or marketability of the fruit or grain quality of the produce (i.e., harvest quality); (d) increased ability of the crop to withstand or prevent plant disease infection and arthropod, nematode, or mollusk pest infestation; and (e) increased ability of the crop to withstand environmental stresses, such as extreme heat, suboptimal moisture, or exposure to phytotoxic chemicals.
[0271] The compounds of the present invention can increase the vigor of treated plants compared to untreated plants by preventing and / or curing plant diseases caused by fungal plant pathogens in the plant's environment. In the absence of such control of plant diseases, the disease reduces plant vigor by consuming plant tissues or sap or by transmitting plant pathogens such as viruses. Even in the absence of fungal plant pathogens, the compounds of the present invention can increase plant vigor by modifying plant metabolism. Generally, the vigor of crop plants will be most significantly increased by treating the plants with the compounds of the present invention when the plants are grown in a non-ideal environment (i.e., an environment that contains one or more aspects unfavorable to the plant achieving its maximum genetic potential, which would be indicative of an ideal environment).
[0272] Of note is a method for increasing the vigor of a crop plant when the plant is grown in an environment that includes a plant disease caused by a fungal plant pathogen. Also of note is a method for increasing the vigor of a crop plant when the plant is grown in an environment that does not include a plant disease caused by a fungal plant pathogen. Also of note is a method for increasing the vigor of a crop plant when the plant is grown in an environment that is less watery than ideal for supporting the growth of the crop plant.
[0273] The compounds of the present invention can also be mixed with one or more biologically active compounds or agents, including fungicides, insecticides, nematicides, bactericides, acaricides, herbicides, herbicide antidotes, growth regulators, such as insect molting inhibitors, and root stimulators, sterilizers, semiochemicals, repellents, attractants, pheromones, feeding stimulants, plant nutrients, other biologically active compounds, or insect pathogenic bacteria, viruses, or fungi to form multi-component pesticides that provide broad-spectrum agricultural protection. Therefore, the present invention also relates to compositions comprising a fungicidally effective amount of a compound of Formula 1 and a biologically effective amount of at least one additional biologically active compound or agent, which may further comprise at least one surfactant, solid diluent, or liquid diluent. Other biologically active compounds or agents can be formulated in compositions that include at least one surfactant, solid diluent, or liquid diluent. In the case of the mixtures of the present invention, one or more other biologically active compounds or agents may be formulated together with the compound of Formula 1 to form a premix, or one or more other biologically active compounds or agents may be formulated separately from the compound of Formula 1 and the formulations may be combined together before application (e.g., in a spray tank) or applied sequentially.
[0274] As noted in the Summary of the Invention, one aspect of the present invention is a fungicidal composition (i.e., a mixture or combination) comprising a compound of Formula 1, its N-oxide, or salt (i.e., component a) and at least one other fungicide (i.e., component b). Of note are combinations in which the other fungicidally active ingredient has a different site of action than the compound of Formula 1. In certain cases, combinations with at least one other fungicidally active ingredient having a similar spectrum of control but a different site of action may be particularly advantageous for resistance management. As such, the compositions of the present invention may further comprise a fungicidally effective amount of at least one additional fungicidally active ingredient having a similar spectrum of control but a different site of action.

Sterols, such as ergosterol, are necessary for membrane structure and function, which are essential for the development of a functional cell wall. Therefore, exposure to these fungicides results in the abnormal growth and eventual death of susceptible fungi. DMI fungicides are divided into several chemical classes: azoles (e.g., triazoles and imidazoles), pyrimidines, piperazines, pyridines, and triazolinethiones. Triazoles include azaconazole, bitertanol, bromuconazole, cyproconazole, difenoconazole, diniconazole (e.g., diniconazole-M), epoxiconazole, etaconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imibenconazole, ipconazole, mefentrifluconazole, metconazole, myclobutanil, penconazole, propiconazole, quinconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole, uniconazole, uniconazole-P, and α-(1-chlorocyclopropyl) -α-[2-(2,2-dichlorocyclopropyl)ethyl]-1H-1,2,4-triazole-1-ethanol, rel-1-[[(2R,3S)-3-(2-chloro-phenyl)-2-(2,4-difluorophenyl)-2-oxiranyl]methyl]-1H-1,2,4-triazole, rel-2-[[(2R,3S)-3-(2-chloro-phenyl)-2-(2,4-difluorophenyl)-2-oxiranyl]methyl]-1,2-dihydro-3H-1,2,4-triazole-3-thione, and rel-1-[[(2R,3S)-3-(2-chlorophenyl)-2-(2,4-difluorophenyl)-2-oxiranyl]methyl]-5-(2-propen-1-ylthio)-1H-1,2,4-triazole.

[0346] In embodiments employing one or more of these various mixing partners, the weight ratio of these various mixing partners (combined) to the compound of Formula 1 is typically between about 1:3000 and about 3000:1. Of note are weight 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 by simple experimentation the biologically effective amount of active ingredient required to achieve the desired spectrum of biological activity. It will be apparent that the inclusion of these additional components can broaden the spectrum of disease control beyond that achieved by the compound of Formula 1 alone.
[0347] In certain cases, the combination of the compound of the present invention with other biologically active (especially fungicidal) compounds or agents (i.e., active ingredients) can produce a superadditive (i.e., synergistic) effect.It is always desirable to reduce the amount of active ingredient released into the environment while ensuring effective pest control.When the synergistic effect of fungicidal active ingredients is manifested at an application rate that provides an agriculturally satisfactory level of fungal control, such a combination can be advantageous for reducing crop production costs and reducing environmental burdens.
[0348] Also, in certain cases, combinations of the compounds of the present invention with other biologically active compounds or agents may result in less-than-additive (i.e., safer) effects on beneficial organisms in agricultural environments. For example, the compounds of the present invention may make herbicides safer on crop plants or protect beneficial insect species (e.g., insect predators, pollinators such as bees) from pesticides.

[0353] Seed treatments can also include one or more species of legume-root nodulating bacteria, such as the microsymbiotic nitrogen-fixing bacterium Bradyrhizobium japonicum. These inoculants can optionally include one or more lipochitooligosaccharides (LCOs), which are nodulation (Nod) factors produced by Rhizobia bacteria during the initiation of nodulation on legume roots. For example, Optimize® brand seed treatment technology uses LCO Promoter Technology in combination with an inoculant. TM It incorporates the following.
[0354] Seed treatments can also include one or more isoflavones, which can increase the level of root colonization by mycorrhizal fungi. Mycorrhizal fungi improve plant growth by increasing root uptake of nutrients such as water, sulfate, nitrate, phosphate, and metals. Examples of isoflavones include, but are not limited to, genistein, biochanin A, formononetin, daidzein, glycitein, hesperetin, naringenin, and pratensein. Formononetin is available as an active ingredient in mycorrhizal inoculant products such as PHC Colonize® AG.
[0355] The seed treatment may also include one or more plant activators that induce systemic acquired resistance in the plant after contact with the pathogen. An example of a plant activator that induces such a protective mechanism is acibenzolar-S-methyl.
