Description

TITLE

FUNGICIDAL PYRAZOLES

FIELD OF THE INVENTION

This invention relates to certain pyrazoles, their N-oxides, salts and compositions, and methods of their use as fungicides.

BACKGROUND OF THE INVENTION

The control of plant diseases caused by fungal plant pathogens is extremely important in achieving high crop efficiency. Plant disease damage to ornamental, vegetable, field, cereal, and fruit crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different sites of action.

DETAILS OF THE INVENTION

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 limitation explicitly indicated. For example, a composition, mixture, process, method, article, or apparatus that comprises 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, mixture, process, method, article, or apparatus.

The transitional phrase "consisting of excludes any element, step, or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase "consisting of appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

The transitional phrase "consisting essentially of is used to define a composition, method or apparatus that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term "consisting essentially of occupies a middle ground between "comprising" and "consisting of.

Where applicants have defined an invention or a portion thereof with an open-ended term such as "comprising," it should be readily understood that (unless otherwise stated) the description should be interpreted to also describe such an invention using the terms "consisting essentially of or "consisting of."

Further, unless expressly stated to the contrary, "or" refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one 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 "an" preceding an element or component of the invention are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore "a" or "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 meant to be singular.

As referred to in the present disclosure and claims, "plant" includes members of Kingdom Plantae, particularly seed plants (Spermatopsida), at all life stages, including young plants (e.g., germinating seeds developing into seedlings) and mature, reproductive stages (e.g., plants producing flowers and seeds). Portions of plants include geotropic members typically growing beneath the surface of the growing medium (e.g., soil), such as roots, tubers, bulbs and corms, and also members growing above the growing medium, such as foliage (including stems and leaves), flowers, fruits and seeds.

As referred to herein, the term "seedling", used either alone or in a combination of words means a young plant developing from the embryo of a seed.

As referred to herein, the term "broadlea ' used either alone or in words such as "broadleaf crop" means dicot or dicotyledon, a term used to describe a group of angiosperms characterized by embryos having two cotyledons.

As used herein, the term "alkylating agent" refers to a chemical compound in which a carbon-containing radical is bound through a carbon atom to a leaving group such as halide or sulfonate, which is displaceable by bonding of a nucleophile to said carbon atom. Unless otherwise indicated, the term "alkylating agent" or "alkylating reagent" does not limit the carbon-containing radical to alkyl; the carbon-containing radicals in alkylating agents include the variety of carbon-bound substituent radicals specified, for example, for R².

Generally when a molecular fragment (i.e. radical) is denoted by a series of atom symbols (e.g., C, H, N, O, S) the implicit point or points of attachment will be easily recognized by those skilled in the art. In some instances herein, particularly when alternative points of attachment are possible, the point or points of attachment may be explicitly indicated by a hyphen ("-"). For example, "-SC≡N" indicates that the point of attachment is the sulfur atom (i.e. thiocyanato, not isothiocyanato).

The term "unsubstituted" in connection with a group such as a ring means the group does not have any substituents other than its one or more attachments to the remainder of Formula 1. The term "optionally substituted" means that the number of substituents can be zero. Unless otherwise indicated, optionally substituted groups may be substituted with as many optional substituents as can be accommodated by replacing a hydrogen atom with a non-hydrogen substituent on any available carbon or nitrogen atom. Commonly, the number of optional substituents (when present) range from 1 to 3. As used herein, the term "optionally substituted" is used interchangeably with the phrase "substituted or unsubstituted" or with the term "(un)substituted."

The number of optional substituents may be restricted by an expressed limitation. For example, the phrase "optionally substituted with up to 3 substituents independently selected from R^3a on carbon atom ring members" means that 0, 1, 2 or 3 substituents can be present (if the number of potential connection points allows). Similarly, the phrase "optionally substituted with up to 5 substituents independently selected from R^3a" means that 0, 1, 2, 3, 4 or 5 substituents can be present if the number of available connection points allows.

When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can vary (e.g., (R ^a)_p in Table 1 wherein p is 0 to 5), then said substituents are independently selected from the group of defined substituents, unless otherwise indicated. When a variable group is shown to be optionally attached to a position, for example (R^3a)_p in Table 1 wherein p may be 0, then hydrogen may be at the position even if not recited in the definition of the variable group. Unless otherwise indicated, a "ring" or "ring system" as a component of Formula 1 (e.g., Q¹ or Q²) is carbocyclic (e.g., phenyl or naphthalenyl) or heterocyclic (e.g., pyridinyl). The term "ring member" refers to an atom (e.g., C, O, N or S) forming the backbone of a ring. The term "ring system" denotes two or more fused rings (e.g., quinazolinyl).

The term "nonaromatic" includes rings that are fully saturated as well as partially or fully unsaturated, provided that none of the rings are aromatic. The term "aromatic" indicates that each of the ring atoms of a fully unsaturated ring are essentially in the same plane and have a /^-orbital perpendicular to the ring plane, and that (4n + 2) π electrons, where n is a positive integer, are associated with the ring to comply with Huckel's rule.

The terms "carbocyclic ring" or "carbocycle" denote a ring wherein the atoms forming the ring backbone are selected only from carbon. When a fully unsaturated carbocyclic ring satisfies Huckel's rule, then said ring is also called an "aromatic carbocyclic ring". The term "saturated carbocyclic ring" refers to a ring having a backbone consisting of carbon atoms linked to one another by single bonds; unless otherwise specified, the remaining carbon valences are occupied by hydrogen atoms.

The terms "heterocyclic ring", "heterocycle" or "heteroaromatic ring system" denote a ring or ring system in which at least one atom forming the ring backbone is not carbon (e.g., N, O or S). Typically a heterocyclic ring contains no more than 3 N atoms, no more than 2 O atoms and no more than 2 S atoms. Unless otherwise indicated, a heterocyclic ring can be a saturated, partially unsaturated or fully unsaturated ring. When a fully unsaturated heterocyclic ring satisfies Huckel's rule, then said ring is also called a "heteroaromatic ring" or "aromatic heterocyclic ring". Unless otherwise indicated, heterocyclic rings can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

In the context of the present invention when an instance of Q¹ and Q² comprises a phenyl or 6-membered heterocyclic ring (e.g., pyridinyl), the ortho, meta and para positions of each ring are relative to the connection of the ring to the remainder of Formula 1.

Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers or as an optically active form.

One skilled in the art recognizes that because in the environment and under physiological conditions salts of chemical compounds are in equilibrium with their corresponding nonsalt forms, salts share the biological utility of the nonsalt forms. Thus a wide variety of salts of the compounds of Formula 1 are useful for control of plant diseases caused by fungal plant pathogens (i.e. are agriculturally suitable). The salts of the compounds of Formula 1 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 acids.

Compounds selected from Formula 1, stereoisomers, N-oxides, and salts thereof, typically exist in more than one form, therefore Formula 1 includes all crystalline and noncrystalline forms of the compounds that Formula 1 represents. Non-crystalline forms include embodiments which are solids such as waxes and gums as well as embodiments which are liquids such as solutions and melts. Crystalline forms include embodiments which represent essentially a single crystal type and embodiments which represent a mixture of polymorphs (i.e. different crystalline 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 arrangements and/or conformations of the molecules in the crystal lattice. Although polymorphs can have the same chemical composition, they can also differ in composition due to the presence or absence of co-crystallized water or other molecules, which can be weakly or strongly bound in the lattice. Polymorphs can differ in such chemical, physical and biological properties as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspensibility, dissolution rate and biological availability. One skilled in the art will appreciate that a polymorph of a compound represented by Formula 1 can exhibit beneficial effects (e.g., suitability for preparation of useful formulations, improved biological performance) relative to another polymorph or a mixture of polymorphs of the same compound represented by Formula 1. Preparation and isolation of a particular polymorph of a compound represented by Formula 1 can be achieved by methods known to those skilled in the art including, for example, crystallization using selected solvents and temperatures.

One or more of the following methods and variations as described in Schemes 1-18 can be used to prepare the compounds of Formula 1. The definitions of Q¹, Q², X, R¹, R^la R² and R⁴ in the compounds of Formulae 1-25 below are as defined above in the Summary of the Invention unless otherwise noted. Formulae la, lb, lc, Id, le, If and lg are various subsets of Formula 1. Substituents for each subset formula are as defined for its parent formula unless otherwise noted

As shown in Scheme 1, Compounds of Formula 1 can be prepared by reaction of a compound of Formula 2 (e.g., 5-aminopyrazoles for X being NR⁴, 5-hydroxypyrazoles for X being O or 5-mercaptopyrazoles for X being S) with a compound of Formula 3 wherein L¹ is a leaving group such as halogen (e.g., CI, Br or I) or (halo)alkylsulfonate (e.g., p- toluenesulfonate, methanesulfonate or trifluoromethanesulfonate) optionally in the presence of a metal catalyst, and generally in the presence of a base and a polar aprotic solvent such as N,N-dimethylformamide or dimethyl sulfoxide. For compounds of Formula 3 wherein Q² is attached through a sp -hybridized carbon atom, L¹ is typically CI, Br, I or a sulfonate (e.g., methanesulfonate). For Compounds of Formula 3 wherein Q² is an aromactic ring lacking an electron-withdrawing substituent(s), or in general, to improve reaction rate, yield or product purity, the use of a metal catalyst (e.g., metal or metal salt) in amounts ranging from catalytic up to superstoichiometric can facilitate the desired reaction. Typically for these conditions, L¹ is Br or I or a sulfonate such as methyl trifluoromethanesulfonate or -OS(0)2(CF2)3CF3. For example, the reaction can be run in the presence of a metal catalyst such as copper salt complexes (e.g., Cul with N,A/"-dimethylethylenediamine, proline or bipyridyl), palladium complexes (e.g., tris(dibenzylideneacetone)dipalladium(0)) or palladium salts (e.g., palladium acetate) with ligands such as 4,5-bis(diphenylphosphino)- 9,9-dimethylxanthene, 2-dicyclohexylphosphino-2',4',6'-triisopropylbiphenyl or 2,2'-bis- (diphenylphosphino)l,l'-binaphthalene, with a base such as potassium carbonate, cesium carbonate, potassium phosphate, sodium phenoxide or sodium tert-butoxide and a solvent such as N,N-dimethylformamide, 1 ,2-dimethoxy ethane, dimethyl sulfoxide, 1,4-dioxane or toluene, optionally containing an alcohol such as ethanol. For relevant references, see PCT Patent Publication WO 2010/020363, and Archives of Pharmacal Research 2002, 25(6), 781-785.

One skilled in the art will appreciate that the leaving group L¹ attached to compounds of Formula 3 should be selected in view of the relative reactivity of other functional groups present on Formula 3 (i.e. substituents attached to Q²), so that the group L¹ is displaced and not the functional group to give the final desired compounds of Formula 1.

General methods useful for preparing starting compounds of Formula 2 are well- known in the art; see, for example, J. Heterocyclic Chem. 1982, 19, 1173-1177, and Organic & Biomolecular Chemistry 2011, 9(10), 3714-3725 for conditions for preparing 5-aminopyrazoles of Formula 2; and Chemical & Pharmaceutical Bulletin 1994, 42(8), 1617-1630 for conditions for preparing 5-hydroxypyrazoles of Formula 2. To prepare 5-thiopyrazoles of Formula 2 the corresponding 5-hydroxypyrazoles can be treated with phosphorus pentasulfide or 2,4-bis(4-methoxyphenyl)-l,3-dithia-2,4-diphosphetane-2,4- disulfide (Lawesson's reagent) in solvents such as toluene, xylene or tetrahydrofuran. For references see, for example, PCT Patent Publication WO 2005/118575, and Justus Liebigs Annalen der Chemie 1908, 361, 251.

Scheme 1

As illustrated in Scheme 2, compounds of Formula 1 can also be prepared by reacting a compound of Formula 4 wherein L¹ is a leaving group such as halogen (e.g., CI, Br or I) or (halo)alkylsulfonate (e.g., /?-toluenesulfonate, methanesulfonate or trifluoromethane- sulfonate) with a compound of Formula 5 under conditions analogous to those described for Scheme 1. For references illustrating the method of Scheme 2 see, for example, Archive for Organic Chemistry 2009, 126-142, Journal of Agricultural and Food Chemistry 2008, 56, 10160-10167, and Biooganic & Medicinal Chemistry Letters 2007, 17, 1189-1192. Scheme 2

4 1

As shown in Scheme 3, intermediates of Formula 4 wherein L¹ is Br or I can be prepared by reaction of compounds of Formula 2 wherein X is NH under diazotization conditions optionally in the presence of copper salts containing bromide or iodide. For example, addition of tert-butyl nitrite to a solution of a 5-aminopyrazole of Formula 2 in the presence of CuBr₂ in a solvent such as acetonitrile provides the corresponding 5- bromopyrazole of Formula 4. Likewise, a 5-aminopyrazole of Formula 2 can be converted to a diazonium salt and then to a corresponding 5-bromo or 5-iodopyrazole of Formula 4 by treatment with sodium nitrite in solvents such as water, acetic acid or trifluoroacetic acid, in the presence of a mineral acid typically containing the same halide atom as L¹ (e.g., aqueous HI solution for L¹ being I), followed by treatment with the corresponding copper(I) or copper(II) salt according to general procedures well-known to those skilled in the art. For a related reference, see J. Comb. Chem. 2003, 5, 118-124.

As shown in Scheme 4, compounds of Formula 4 wherein L¹ is Br can also be prepared by reacting pyrazolones of Formula 6 with phosphorus tribromide using the method described in Tetrahedron Lett. 2000, 47(24), 4713-4716. Pyrazolones of Formula 6 can be prepared by condensation of ketoesters of Formula 7 with alkylhydrazines using the method described in J. Heterocyclic Chem. 1987, 24, 149-153. Scheme 4

As shown in Scheme 5, compounds of Formula 4 wherein L¹ is fluoroalkylsulfonyl can be prepared from compounds of Formula 2 wherein X is O using the method described in Synlett 2004, (5), 795-798.

such as CF₃ or CF₃(CF₂)₃ wherein X is O wherein L is RfS0₂0-

In an alternative method, as shown in Scheme 6, compounds of Formula 1 are prepared by reacting a compound of Formula 8 with an alkylating agent of formula Li-CHRiR¹^¹ wherein L¹ is a leaving group such as halogen (e.g., CI, Br or I) or (halo)alkylsulfonate (e.g., /?-toluenesulfonate, methanesulfonate or trifluoromethanesulfonate), preferably in the presence of a base such as l ,8-diazabicyclo[5.4.0]undec-7-ene, potassium carbonate or potassium hydroxide, and in a solvent such as N,N-dimethylformamide, tetrahydrofuran, toluene or water. General procedures for alkylations of this type are well-known in the art and can be readily adapted to prepare compounds of the present invention. Particularly useful alkylating agents for preparing compounds of Formula 1 wherein R¹ and R^{l a} are H are diazomethane or iodomethane using general procedures known in the art, such as those described in Canada Journal of Chemistry 1986, 64, 221 1-2219, and Heterocycles 2000, 55(12), 2775-2780. Compounds of Formula 1 wherein R¹ and R^{l a} form an optionally substituted cyclopropyl ring can likewise be prepared by reaction of a compound of Formula 8 with an organometallic reagent, such as tricyclopropylbismuth, in the presence of a catalyst, such as copper acetate, under conditions known in the art such as those described in J. Am. Chem. Soc. 2007, 129(1), 44-45. Scheme 6

Compounds of Formula 8 are known and can be prepared by a variety of methods disclosed in the chemical literature. For example, as shown in Scheme 7, compounds of Formula 8 wherein R² is halogen or alkyl can be prepared from the corresponding compounds of Formula 9 wherein R² is H by halogenation or alkylation. Typically halogenation can be achieved using a variety of halogenating agents known in the art such as elemental halogen (e.g., Cl₂, Br₂, ½), sulfuryl chloride, iodine monochloride or a N-halosuccinimide (e.g., NBS, NCS, NIS) in an appropriate solvent such as N,N-dimethylformamide, carbon tetrachloride, acetonitrile, dichloromethane or acetic acid. Alkylation is achieved by reacting a compound of Formula 9 with a metalating agent, followed by an alkylating agent of formula R²-L! (wherein L¹ is a leaving group such as CI, Br, I or a sulfonate, for example, /?-toluenesulfonate, methanesulfonate or trifluoromethanesulfonate). Suitable metalating agents include, for example, /? -butyl lithium (ft-BuLi), lithium diisopropylamide (LDA) or sodium hydride (NaH). As used herein, the terms "alkylation" and "alkylating agent" are not limited to R² being an alkyl group, and include in addition to alkyl such groups as alkylthio, haloalkyl, alkenyl, haloalkenyl, alkynyl, and the like. For reaction conditions see, Journal of Medicinal Chemistry 2003, 46(16), 3463-3475, Heterocycles 1997, 44, 67-70, Synthetic Communications 2008, 55(5), 674-683, and PCT Patent Publication WO 2009/137651, Example 39, Step D.

Also shown in Scheme 7, intermediate compounds of Formula 9 can be prepared by reacting a compound of Formula 10 with hydrazine hydrochloride. The reaction can be run in a variety of solvents, but optimal yields are typically obtained when the reaction is run in ethanol at a temperature between about room temperature and the reflux temperature of the solvent. General procedures for this type of reaction are well documented in the chemical literature; see, for example, Bioorganic & Medicinal Chemistry 2005, 13(6), 2097-2107, Journal of Heterocyclic Chemistry 1989, 26(4), 1147-1158, and PCT Patent Publication WO 2009/137651, Example 39, Step C.

As shown in Scheme 8, compounds of Formula 10 can be prepared from ketones of Formula 11 and N,N-dimethylformamide dimethyl acetal using the method described by Maya et al, Bioorganic & Medicinal Chemistry 2005, 13(6), 2097-2107. The reaction is typically conducted in a solvent such as benzene, toluene or xylenes at a temperature between about room temperature and the reflux temperature of the solvent.

Scheme 8

Ketones of Formula 11 can be prepared by reaction of acid chlorides of Formula 12 with a compound of formula Q²X-H under Friedel-Crafts condensation reaction conditions. Friedel-Crafts reactions are documented in a variety of published references; see, for example, J. March, Advanced Organic Chemistry, McGraw-Hill, New York, p. 490 and references cited therein, and PCT Patent Publications WO 2005/037758 and WO 2009/137651 (Example 39, Step A).

Scheme 9

Compounds of Formula 1 can also be prepared as shown in Scheme 10. In this method a compound of Formula 13 is first treated with an organometallic agent of Formula 14 such an alkyl lithium base (e.g., n-butyllithium, s-butyllithium or lithium diisopropylamide) or a Grignard reagent in a solvent such as toluene, ethyl ether, tetrahydrofuran or dimethoxymethane at temperatures ranging from about -78 °C to ambient temperature. Anions of Formula 13a are then contacted with an electrophile of Formulae 15 or 16. The use and choice of an appropriate electrophile of Formulae 15 or 16 will depend on the desired compound of Formula 1 and will be apparent to one skilled in chemical synthesis. For example, aldehydes of the formula Q²CHO provide compounds Formula 1 wherein X is CH(OH) and chlorosulfides of formula QiSCl or disulfies formula of QiS-S-Q¹ provide compounds Formula 1 wherein X is S. There are a wide-variety of general methods described in the synthetic literature for metallation/alkylation reactions which can be readily adapted to prepare compounds of the present invention; see, for example, J. Org. Chem. 2010, 75, 984-987.

Scheme 10

Electrophiles of Formulae 15 and 16 are commercially available and can be prepared by methods known in the art. Compounds of Formula 13 are known and can be prepared by methods analogous to those disclosed in Schemes 3 and 4 and by a variety of methods disclosed in the chemical literature.

As shown in Scheme 11, keto compounds of Formula 17 can be treated with alkylmagnesium halides to provide compounds of Formula la (i.e Formula 1 wherein X is CR^5aOR^5b, R^5a is alkyl and R^5b is H). Typically the reaction is run in the presence of zinc chloride and in a solvent such as diethyl ether or tetrahydrofuran at temperatures from about 0 to 100 °C (for references see, for exmple, Organic Lett. 2009, 11, 1659-1662, and J. Am. Chem. Soc. 2006, 128, 9998-9999). Scheme 11

As shown in Scheme 12, compounds of Formula 17 can be prepared by contacting a compound of Formula 18 with an acid chloride of Formula 19 in the presence of a Lewis acid (e.g., aluminum chloride, boron trifluoride diethyl etherate or tin tetrachloride) in a solvent such as dichloromethane, tetrachloroethane, or nitrobenzene, at temperatures ranging between about 0 to 200 °C.

As shown in Scheme 13, compounds of Formula lb (i.e. Formula 1 wherein X is NR⁴ and R⁴ is H) can be prepared by reacting a compound of Formula 20 with an alkylhydrazine of Formula 21 in a solvent such as ethanol or methanol and optionally in the presence of an acid or base catalyst such as acetic acid, piperidine or sodium methoxide, according to general procedures known in the art.

As shown in Scheme 14, compounds of Formula 20 can be prepared by reaction of corresponding ketene dithioacetal compounds of Formula 22 with compounds of formula Q²-NH₂ optionally in the presence of a base, such as sodium hydride or ethylmagnesium chloride, in solvents such as toluene, tetrahydrofuran or dimethoxymethane, at temperatures ranging from -10 °C to the boiling point of the solvent. Methods useful for preparing compounds of Formula 20 are known in the art; see, for example, J. Heterocycl. Chem. 1975, 12(1), 139.

As shown in Scheme 15, compounds of Formula lb (i.e. Formula 1 wherein X is NR⁴ and R⁴ is H) can also be prepared by condensing a compound of Formula 23 with an alkylhydrazine of Formula 21 in a solvent such as tetrahyrofuran, ethanol or methanol and optionally in the presence of an acid or base catalyst such as acetic acid, piperidine or sodium methoxide, according to general procedures known in the art (see Chemistry of Heterocyclic Compounds 2011, 47(8), 970-976). Compounds of Formula 23 can readily be prepared by reacting enolates of Formula 24 with isothiocyantes followed by methylsulfanylation using the method described by Tong et al, Bioorganic & Medicinal Chemistry Letters 2008, 18, 5206-5208. Compounds of Formula 24 can be prepared from commercially available amines according to procedures described in the art (see Synthetic Communications 2007, 37, 985-991). The method of Scheme 15 is also illustrated by Example 1, Steps A-B.

Scheme 15

Compounds of Formula 1 can be subjected to various nucleophilic and metallation reactions to add substituents or modify existing substituents, and thus provide other functionalized compounds of Formula 1. For example, as shown in Scheme 16, compounds of Formula lc (i.e. Formula 1 wherein X in NR⁴ and R⁴ is other than H) can be prepared by reacting corresponding compounds of Formula lb (i.e. Formula 1 wherein X is NR⁴ and R⁴ is H) with an electrophile comprising R⁴ (i.e. Formula 25) typically in the presence of a base such as NaH and a polar solvent such as N,N-dimethylformamide. In this context the expression "electrophile comprising R⁴" means a chemical compound capable of transferring an R⁴ moiety to a nucleophile (such as the nitrogen atom attached to Q² in Formula lb). Often electrophiles comprising R⁴ have the formula R L² wherein L² is a nucleofuge (i.e. leaving group in nucleophilic reactions). Typical nucleofuges include halogens (e.g., CI, Br, I) and sulfonates (e.g., OS(0)₂CH₃, OS(0)₂CF₃, OS(0)2-(4-CH₃-Ph)). However, some electrophiles comprising R⁴ do not comprise a nucleofuge; an example is sulfur trioxide (S0₃), which after deprotonation (such as by a base of the formulae M⁺H^~ wherein M⁺ is a cation) of the nitrogen atom attached to Q² in Formula lb, can bond to the nitrogen atom as a -SO3M substituent.

As shown in Scheme 17, a fluoro can be introduce at the 3-position of the pyrazole ring by treating compounds Formula Id (i.e. Formula 1 wherein R² is chlorine) with potassium fluoride or cesium fluoride in presence of a solvent such as dimethyl sulfoxide or A ,N-dimethylformamide at 0-25 °C for time periods of 30 minutes to 4 h, using procedures such as described in Zhurnal Organicheskoi Khimii 1983, 19, 2164-2173.

Scheme 17

As shown in Scheme 18, sulfoxides and sulfones of Formula lg (i.e. Formula 1 wherein X is S(=0)_m and m is 1 or 2) can be prepared by oxidation of compounds of Formula If (i.e. Formula 1 wherein X is S). Typically an oxidizing agent in an amount from about 1 to 4 equivalents, depending on the oxidation state of the desired product, is added to a mixture of a compound of Formula If and a solvent. Useful oxidizing agents include Oxone® (potassium peroxymonosulfate), potassium permanganate, hydrogen peroxide, sodium periodate, peracetic acid and 3-chloroperbenzoic acid. The solvent is selected with regard to the oxidizing agent employed. Aqueous ethanol or aqueous acetone is preferably used with potassium peroxymonosulfate, and dichloromethane is generally preferable with 3-chloroperbenzoic acid. Useful reaction temperatures typically range from about -78 to 90 °C. Oxidation reactions of this type are described by Brand et al, J. Agric. Food Chem. 1984, 32, 221-226 and Ouyang, et al, J. Agric. Food Chem. 2008, 56, 10160-10167.

It is recognized by one skilled in the art that various functional groups can be converted into others to provide different compounds of Formula 1. For example, compounds of Formula 1 in which R² is methyl, ethyl, cyclopropyl, and the like, can be modified by free-radical halogenation to form compounds of Formula 1 wherein R² is halomethyl, haloethyl, halocyclopropyl, and the like. Compounds of Formula 1 wherein R² is halomethyl can be used to prepare compounds of Formula 1 wherein R² is hydroxymethyl or cyanomethyl. Compounds of Formula 1, or intermediates for their preparation, may contain aromatic nitro groups, which can be reduced to amino groups, and then converted via reactions well-known in the art (e.g., Sandmeyer reaction) to various halides. By similar known reactions, aromatic amines (anilines) can be converted via diazonium salts to phenols, which can then be alkylated to prepare compounds of Formula 1 with alkoxy substituents. Likewise, aromatic halides such as bromides or iodides prepared via the Sandmeyer reaction can react with alcohols under copper-catalyzed conditions, such as the Ullmann reaction or known modifications thereof, to provide compounds of Formula 1 that contain alkoxy substituents. Additionally, some halogen groups, such as fluorine or chlorine, can be displaced with alcohols under basic conditions to provide compounds of Formula 1 containing the corresponding alkoxy substituents. The resultant alkoxy compounds can themselves be used in further reactions to prepare compounds of Formula 1 wherein R^3a is - U-V-T (see, for example, PCT Patent Publication WO 2007/149448). Compounds of Formula 1 or precursors thereof in which R² is halide, preferably bromide or iodide, are particularly useful intermediates for transition metal-catalyzed cross-coupling reactions to prepare compounds of Formula 1. These types of reactions are well documented in the literature; see, for example, Tsuji in Transition Metal Reagents and Catalysts: Innovations in Organic Synthesis, John Wiley and Sons, Chichester, 2002; Tsuji in Palladium in Organic Synthesis, Springer, 2005; and Miyaura and Buchwald in Cross Coupling Reactions: A Practical Guide, 2002; and references cited therein.

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula 1 may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme above, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula 1. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula 1. One skilled in the art will also recognize that compounds of Formula 1 and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Formulation/Utility

A compound of this invention will generally be used as a fungicidal active ingredient in a composition, i.e. formulation, with at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents, which serve as a carrier. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature.

Useful formulations include both liquid and solid compositions. Liquid compositions include solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like, which optionally can be thickened into gels. The general types of aqueous liquid compositions are soluble concentrate, suspension concentrate, capsule suspension, concentrated emulsion, microemulsion and suspo-emulsion. The general types of nonaqueous liquid compositions are emulsifiable concentrate, microemulsifiable concentrate, dispersible concentrate and oil dispersion.

The general types of solid compositions are dusts, powders, granules, pellets, prills, pastilles, tablets, filled films (including seed coatings) and the like, 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 treatment. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay 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 primarily used as intermediates for further formulation.

Sprayable formulations are typically extended in a suitable medium before spraying. Such liquid and solid formulations are formulated to be readily diluted in the spray medium, usually water. Spray volumes can range from about one to several thousand liters per hectare, but more typically are in the range from about ten to several hundred liters per hectare. Sprayable formulations can be tank mixed with water or another suitable medium for foliar treatment by aerial or ground application, or for application to the growing medium of the plant. Liquid and dry formulations can be metered directly into drip irrigation systems or metered into the furrow during planting. Liquid and solid formulations can be applied onto seeds of crops and other desirable vegetation as seed treatments before planting to protect developing roots and other subterranean plant parts and/or foliage through systemic uptake.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

The solid and liquid compositions of the present invention often include one or more surfactants. When added to a liquid, surfactants (also known as "surface-active agents") generally modify, most often reduce, the surface tension of the liquid. Depending on the nature of the hydrophilic and lipophilic groups in a surfactant molecule, surfactants can be useful as wetting agents, dispersants, emulsifiers or defoaming agents.

Surfactants can be classified as nonionic, anionic or cationic. Nonionic surfactants useful for the present compositions include, but are not limited to: alcohol alkoxylates such as alcohol alkoxylates based on natural and synthetic alcohols (which may be branched or linear) and prepared from the alcohols and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof; amine ethoxylates, alkanolamides and ethoxylated alkanolamides; alkoxylated triglycerides such as ethoxylated soybean, castor and rapeseed oils; alkylphenol alkoxylates such as octylphenol ethoxylates, nonylphenol ethoxylates, dinonyl phenol ethoxylates and dodecyl phenol ethoxylates (prepared from the phenols and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof); block polymers prepared from ethylene oxide or propylene oxide and reverse block polymers where the terminal blocks are prepared from propylene oxide; ethoxylated fatty acids; ethoxylated fatty esters and oils; ethoxylated methyl esters; ethoxylated tristyrylphenol (including those prepared 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 glycols (pegs); polyethylene glycol fatty acid esters; silicone-based surfactants; and sugar-derivatives such as sucrose esters, alkyl polyglycosides and alkyl polysaccharides.

Nonionic, anionic and cationic surfactants and their recommended uses are disclosed 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.

Compositions of this invention 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 may control: pH (buffers), foaming during processing (antifoams such polyorganosiloxanes), sedimentation of active ingredients (suspending agents), viscosity (thixotropic thickeners), in-container microbial growth (antimicrobials), product freezing (antifreezes), color (dyes/pigment dispersions), wash-off (film formers or stickers), 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, annual International and North American editions published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; and PCT Publication WO 03/024222.

The compound of Formula 1 or Formula 1A and any other active ingredients are typically incorporated 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 water-immiscible, an emulsifier is typically added to emulsify the active-containing solvent upon dilution with water. Active ingredient slurries, with particle diameters of up to 2,000 μιη can be wet milled using media mills to obtain particles with average diameters below 3 μιη. 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 usually require dry milling processes, which produce average particle diameters in the 2 to 10 μιη range. Dusts and powders can be prepared by blending and usually grinding (such as with a hammer mill or fluid-energy mill). Granules and pellets can be prepared by spraying the active material upon preformed granular carriers 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, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. 4,144,050, U.S. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. 5,180,587, U.S. 5,232,701 and U.S. 5,208,030. Films can be prepared as taught in GB 2,095,558 and U.S. 3,299,566.

Water-soluble and water-dispersible formulations are typically diluted with water to form aqueous compositions before application. Aqueous compositions for direct applications to the plant or portion thereof (e.g., spray tank compositions) typically at least about 1 ppm or more (e.g., from 1 ppm to 100 ppm) of the compound(s) of this invention.

The compounds of this invention are useful as plant disease control agents. The present invention therefore further comprises a method for controlling plant diseases caused by fungal plant pathogens comprising applying to the plant or portion thereof to be protected, or to the plant seed to be protected, an effective amount of a compound of the invention or a fungicidal composition containing said compound. The compounds and/or compositions of this invention provide control of diseases caused by a broad spectrum of fungal plant pathogens in the Basidiomycete, Ascomycete, Oomycete and Deuteromycete classes. They are effective in controlling a broad spectrum of plant diseases, particularly foliar pathogens of ornamental, turf, vegetable, field, cereal, and fruit crops. These pathogens include: Oomycetes, including Phytophthora diseases such as Phytophthora infestans, Phytophthora megasperma, Phytophthora parasitica, Phytophthora cinnamomi and Phytophthora capsici, Pythium diseases such as Pythium aphanidermatum, and diseases in the Peronosporaceae family such as Plasmopara viticola, Peronospora spp. (including Peronospora tabacina and Peronospora parasitica), Pseudoperonospora spp. (including Pseudoperonospora cubensis) and Bremia lactucae; Ascomycetes, including Alternaria diseases such as Alternaria solani and Alternaria brassicae, Guignardia diseases such as Guignardia bidwell, Venturia diseases such as Venturia inaequalis, Septoria diseases such as Septoria nodorum and Septoria tritici, powdery mildew diseases such as Erysiphe spp. (including Erysiphe graminis and Erysiphe polygoni), Uncinula necatur, Sphaerotheca fuliginea, Podosphaera leucotricha and Pseudocercosporella herpotrichoides, Botrytis diseases such as Botrytis cinerea, Monilinia fructicola, Sclerotinia diseases such as Sclerotinia sclerotiorum, Sclerotinia minor, Magnaporthe grisea, and Phomopsis viticola, Helminthosporium diseases such as Helminthosporium tritici repentis and Pyrenophora teres, anthracnose diseases such as Glomerella or Colletotrichum spp. (such as Colletotrichum graminicola and Colletotrichum orbiculare), and Gaeumannomyces graminis; Basidiomycetes, including rust diseases caused by Puccinia spp. (such as Puccinia recondita, Puccinia striiformis, Puccinia hordei, Puccinia graminis and Puccinia arachidis), Hemileia vastatrix and Phakopsora pachyrhizi; other pathogens including Rutstroemia floccosum (also known as Sclerotinia homoeocarpa); Rhizoctonia spp. (such as Rhizoctonia solani); Fusarium diseases such as Fusarium roseum, Fusarium graminearum and Fusarium oxysporumVerticillium dahliae; Sclerotium rolfsii; Rynchosporium secalis; Cercosporidium personatum, Cercospora arachidicola and Cercospora beticola; Rhizopus spp. (such as Rhizopus stolonifer); Aspergillus spp. (such as Aspergillus flavus and Aspergillus parasiticus); and other genera and species closely related to these pathogens. In addition to their fungicidal activity, the compositions or combinations also have activity against bacteria such as Erwinia amylovora, Xanthomonas campestris, Pseudomonas syringae, and other related species. Furthermore, the compounds of this invention are useful in treating postharvest diseases of fruits and vegetables caused by fungi and bacteria. These infections can occur before, during and after harvest. For example, infections can occur before harvest and then remain dormant until some point during ripening (e.g., host begins tissue changes in such a way that infection can progress); also infections can arise from surface wounds created by mechanical or insect injury. In this respect, the compounds of this invention can reduce losses (i.e. losses resulting from quantity and quality) due to postharvest diseases which may occur at any time from harvest to consumption. Treatment of postharvest diseases with compounds of the invention can increase the period of time during which perishable edible plant parts (e.g, fruits, seeds, foliage, stems, bulbs, tubers) can be stored refrigerated or un-refrigerated after harvest, and remain edible and free from noticeable or harmful degradation or contamination by fungi or other microorganisms. Treatment of edible plant parts before or after harvest with compounds of the invention can also decrease the formation of toxic metabolites of fungi or other microorganisms, for example, mycotoxins such as aflatoxins. Plant disease control is ordinarily accomplished by applying an effective amount of a compound of this invention either pre- or post-infection, to the portion of the plant to be protected such as the roots, stems, foliage, fruits, seeds, tubers or bulbs, or to the media (soil or sand) in which the plants to be protected are growing. The compounds can also be applied to seeds to protect the seeds and seedlings developing from the seeds. The compounds can also be applied through irrigation water to treat plants. Control of postharvest pathogens which infect the produce before harvest is typically accomplished by field application of a compound of this invention, and in cases where infection occurs after harvest the compounds can be applied to the harvested crop as dips, sprays, fumigants, treated wraps and box liners.

Rates of application for these compounds (i.e. a fungicidally effective amount) can be influenced by factors such as the plant diseases to be controlled, the plant species to be protected, ambient moisture and temperature and should be determined under actual use conditions. One skilled in the art can easily determine through simple experimentation the fungicidally effective amount necessary for the desired level of plant disease control. Foliage can normally be protected when treated at a rate of from less than about 1 g/ha to about 5,000 g/ha of active ingredient. Seed and seedlings can normally be protected when seed is treated at a rate of from about 0.1 to about 10 g per kilogram of seed.

Compounds of this invention can also be mixed with one or more other biologically active compounds or agents including fungicides, insecticides, nematocides, bactericides, acaricides, herbicides, herbicide safeners, growth regulators such as insect molting inhibitors and rooting stimulants, chemosterilants, semiochemicals, repellents, attractants, pheromones, feeding stimulants, plant nutrients, other biologically active compounds or entomopathogenic bacteria, virus or fungi to form a multi-component pesticide giving an even broader spectrum of agricultural protection. Thus the present invention also pertains to a composition comprising a compound of Formula 1 (in a fungicidally effective amount) and at least one additional biologically active compound or agent (in a biologically effective amount) and can further comprise at least one of a surfactant, a solid diluent or a liquid diluent. The other biologically active compounds or agents can be formulated in compositions comprising at least one of a surfactant, solid or liquid diluent. For mixtures of the present invention, one or more other biologically active compounds or agents can be formulated together with a compound of Formula 1, to form a premix, or one or more other biologically active compounds or agents can be formulated separately from the compound of Formula 1, and the formulations combined together before application (e.g., in a spray tank) or, alternatively, applied in succession.

Further descriptions of these classes of fungicidal compounds are provided below. (1) "Methyl benzimidazole carbamate (MBC) fungicides" (Fungicide Resistance Action Committee (FRAC) code 1) inhibit mitosis by binding to β-tubulin during microtubule assembly. Inhibition of microtubule assembly can disrupt cell division, transport within the cell and cell structure. Methyl benzimidazole carbamate fungicides include benzimidazoles and thiophanates. The benzimidazoles include benomyl, carbendazim, fuberidazole and thiabendazole. The thiophanates include thiophanate and thiophanate-methy 1.

Therefore, exposure to these fungicides results in abnormal growth and eventually death of sensitive fungi. Amine/morpholine fungicides (also known as non-DMI sterol biosynthesis inhibitors) include morpholines, piperidines and spiroketal-amines. The morpholines include aldimorph, dodemorph, fenpropimorph, tridemorph and trimorphamide. The piperidines include fenpropidin and piperalin. The spiroketal-amines include spiroxamine.

(11) "Quinone outside inhibitor (Qol) fungicides" (Fungicide Resistance Action Committee (FRAC) code 11) inhibit Complex III mitochondrial respiration in fungi by affecting ubiquinol oxidase. Oxidation of ubiquinol is blocked at the "quinone outside" (Q₀) site of the cytochrome bc\ complex, which is located in the inner mitochondrial membrane of fungi. Inhibiting mitochondrial respiration prevents normal fungal growth and development. Quinone outside inhibitor fungicides (also known as strobilurin fungicides) include methoxyacrylates, methoxycarbamates, oximinoacetates, oximinoacetamides, oxazolidinediones, dihydrodioxazines, imidazolinones and benzylcarbamates.

The aryloxyquinolines include quinoxyfen and tebufloquin. The quinazolinones include proquinazid.

(14) "Lipid peroxidation inhibitor fungicides" (Fungicide Resistance Action

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 weight ratio of these various mixing partners (in total) 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 (for example ratios between about 1 :30 and about 30: 1). One skilled in the art can easily determine through simple experimentation the biologically effective amounts of active ingredients necessary for the desired spectrum of biological activity. It will be evident that including these additional components may expand the spectrum of diseases controlled beyond the spectrum controlled by the compound of Formula 1 alone.

In certain instances, combinations of a compound of this invention with other biologically active (particularly fungicidal) compounds or agents (i.e. active ingredients) can result in a greater-than-additive (i.e. synergistic) effect. Reducing the quantity of active ingredients released in the environment while ensuring effective pest control is always desirable. When synergism of fungicidal active ingredients occurs at application rates giving agronomically satisfactory levels of fungal control, such combinations can be advantageous for reducing crop production cost and decreasing environmental load.

Of note is a combination of a compound of Formula 1 with at least one other fungicidal active ingredient. Of particular note is such a combination where the other fungicidal active ingredient has different site of action from the compound of Formula 1. In certain instances, a combination with at least one other fungicidal active ingredient having a similar spectrum of control but a different site of action will be particularly advantageous for resistance management. Thus, a composition of the present invention can further comprise a biologically effective amount of at least one additional fungicidal active ingredient having a similar spectrum of control but a different site of action.

Of particular note are compositions which in addition to a compound of Formula 1 include at least one compound selected from the group consisting of (1) alkylenebis(dithiocarbamate) fungicides; (2) cymoxanil; (3) phenylamide fungicides; (4) proquinazid (6-iodo-3-propyl-2-propyloxy-4(3H)-quinazolinone); (5) chlorothalonil; (6) carboxamides acting at complex II of the fungal mitochondrial respiratory electron transfer site; (7) quinoxyfen; (8) metrafenone; (9) cyflufenamid; (10) cyprodinil; (11) copper compounds; (12) phthalimide fungicides; (13) fosetyl-aluminum; (14) benzimidazole fungicides; (15) cyazofamid; (16) fluazinam; (17) iprovalicarb; (18) propamocarb; (19) validomycin; (20) dichlorophenyl dicarboximide fungicides; (21) zoxamide; (22) fluopicolide; (23) mandipropamid; (24) carboxylic acid amides acting on phospholipid biosynthesis and cell wall deposition; (25) dimethomorph; (26) non-DMI sterol biosynthesis inhibitors; (27) inhibitors of demethylase in sterol biosynthesis; (28) bc\ complex fungicides; and salts of compounds of (1) through (28).

Sauter et al., Angew. Chem. Int. Ed. 1999, 38, 1328-1349). Other fungicidal compounds that inhibit the bc\ complex in the mitochondrial respiration chain include famoxadone and fenamidone.

Copper compounds (group (11)) include compounds such as copper oxychloride, copper sulfate and copper hydroxide, including compositions such as Bordeaux mixture (tribasic copper sulfate). Phthalimides (group (12)) include compounds such as folpet and captan. Benzimidazole fungicides (group (14)) include benomyl and carbendazim. Dichlorophenyl dicarboximide fungicides (group (20)) include chlozolinate, dichlozoline, iprodione, isovaledione, myclozolin, procymidone and vinclozolin.

Non-DMI sterol biosynthesis inhibitors (group (26)) include morpholine and piperidine fungicides. The morpho lines and piperidines are sterol biosynthesis inhibitors that have been shown to inhibit steps in the sterol biosynthesis pathway at a point later than the inhibitions achieved by the DMI sterol biosynthesis (group (27)). The morpho lines include aldimorph, dodemorph, fenpropimorph, tridemorph and trimorphamide. The piperidines include fenpropidin.

BIOLOGICAL EXAMPLES OF THE INVENTION

General protocol for preparing test suspensions for Tests A-E: the test compounds were first dissolved in acetone in an amount equal to 3% of the final volume and then suspended at the desired concentration (in ppm) in acetone and purified water (50/50 mix by volume) containing 250 ppm of the surfactant Trem® 014 (polyhydric alcohol esters). The resulting test suspensions were then used in Tests A-E. Spraying a 200 ppm test suspension to the point of run-off on the test plants was the equivalent of a rate of 800 g/ha.

TEST A

The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Puccinia recondita f. sp. tritici (the causal agent of wheat leaf rust) and incubated in a saturated atmosphere at 20 °C for 24 h, and then moved to a growth chamber at 20 °C for 7 days, after which time visual disease ratings were made.

TEST B

The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Septoria tritici (the causal agent of wheat leaf blotch) and incubated in a saturated atmosphere at 24 °C for 48 h, and then moved to a growth chamber at 20 °C for 19 days, after which time visual disease ratings were made.

TEST C

The test suspension was sprayed to the point of run-off on tomato seedlings. The following day the seedlings were inoculated with a spore suspension of Botrytis cinerea (the causal agent of tomato Botrytis) and incubated in a saturated atmosphere at 20 °C for 48 h, and then moved to a growth chamber at 24 °C for 3 days, after which time visual disease ratings were made.

TEST D

The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore dust of Blumeria graminis f. sp. tritici, (also known as Erysiphe graminis f. sp. tritici, the causal agent of wheat powdery mildew) and incubated in a growth chamber at 20 °C for 8 days, after which time visual disease ratings were made.

TEST E

The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Septoria nodorum (the causal agent of Septoria glume blotch) and incubated in a saturated atmosphere at 24 °C for 48 h, and then moved to a growth chamber at 20 °C for 9 days, after which time visual disease ratings were made.

Results for Tests A-E are given in Table A. In the Table, a rating of 100 indicates 100% disease control and a rating of 0 indicates no disease control (relative to the controls). A dash (-) indicates no test results. An asterisk "*" next to the rating value indicates a 40 ppm test suspension was used.
