The present invention relates to substituted pyrimidine derivatives, as well as N-oxides thereof and agriculturally acceptable salts thereof, and their use to control undesired plant growth, in particular in crops of useful plants. The invention extends to herbicidal compositions comprising such compounds, N-oxides and/or salts as well as mixtures of the same with one or more further active ingredient (such as, for example, an herbicide, fungicide, insecticide and/or plant growth regulator) and/or a safener.
A large number of substituted pyrimidine derivatives are known in the art. For example, International Patent Publication No. WO 98/09960 describes 2,4-disubstituted pyrimidine derivatives for medicinal use, whilst Stansfield at al. (2004, Bioorg. Med. Chem. Lett. 14:5085-5088) describe 6-(4-methoxy-benzylamino)-5-nitro-2-thiophen-2yl-pyrimidine-4-carboxylic acid methyl ester as an intermediate in their exploration of 5,6-dihydroxypyrimidine-4-carboxylic acids as compounds for the treatment of hepatitis C. Reid & Gernfried (1988, Liebigs Annalen der Chemie 7:643-8) describe certain 4-pyrimidine carboxylic acids and derivatives thereof, wherein the pyrimidine ring carries inter alia a substituted amino group at the 6 position. These compounds are used as intermediates in the synthesis of diazepines and azaphenalenes. Britikova et al. (1966 Khimiya Geterotsiklicheskikh Soedinenii 5:783-90) describe the synthesis and properties of amino derivatives of 5-(hydroxymethyl)pyrimidine-4-carboxylic acid lactone, in studying derivatives of orotic acid and its analogs.
Substituted pyrimidine derivatives comprising an optionally substituted cyclopropyl or optionally substituted phenyl group at position 2 in combination with inter alia a nitro or optionally substituted amino group at the position 6 of the pyrimidine ring and their use as herbicides are disclosed in International Patent Publication No. WO 2005/063721. International Patent Publication No. WO 2007/082076 discloses a number of 2-(poly-substituted aryl)-6-amino-5-halo-4-pyrimidine carboxylic acids and their use as herbicides, whilst International Patent Publication No. WO 2007/092184 discloses certain substituted pyrimidine carboxylic acid derivatives as compounds capable of improving the harvestability of crops.
In part, due to the evolution of herbicide-resistant weed populations, and herbicide-resistant crops becoming volunteer weeds, there is a continuing need to control such undesired plant growth in particular in crops of useful plants. Other factors, for example, the demand for cheaper, more effective herbicides, and for herbicides with an improved environmental profile (e.g. safer, less toxic etc.) also drive the need to identify novel herbicidal compounds.
The present invention is based on the finding that substituted amino-pyrimidine derivatives, in particular where the amino group is substituted with an optionally substituted 3-8 membered saturated, unsaturated or aromatic ring, are particularly good herbicidal compounds.

General methods for the production of compounds of formula (I) are described below. Unless otherwise stated in the text, the substitutents A, R5, P, W, Q, Y and Z are as defined hereinbefore. The abbreviation LG as used herein refers to any suitable leaving group, and includes halogen, sulphonate, and sulphone groups. The groups R as used herein are, independently of each other, alkyl or substituted alkyl groups. The groups R′ may, independently of each other, take a range of values depending on the particular structure of the molecule in which they are present; the skilled man will recognise what values are applicable in each case, particularly in view of the definition of compounds of formula (I) as described hereinbefore.
Compounds of formula (I) may be prepared from compounds of formula (A) as shown in reaction scheme 1.
For example, a compound of formula (I), in which A is a ring linked to the pyrimidine ring through a nitrogen atom, may be prepared by reaction of a compound of formula (A) with A-H (e.g. piperidine, pyrrole), optionally in the presence of a suitable base (e.g. an amine base, such as triethylamine), in a suitable solvent (for example an alcohol, such as methanol)—see reaction scheme 2 below. The reaction may be performed at ambient temperature or preferably, at an elevated temperature. This transformation may also be performed in the presence of a suitable metal (e.g. palladium) catalyst, optionally complexed by any suitable ligands (e.g. phosphine ligands, such as Josiphos).
In a second example (see reaction scheme 3) a compound of formula (I), in which A is a group attached through a carbon atom, may be prepared by reacting a suitable metal or metalloid derivative A-M (e.g. a boronic acid or ester, a trialkyltin derivative, a zinc derivative or a Grignard reagent) with a compound of formula A in the presence of a suitable base (e.g. an inorganic base, such as potassium phosphate or caesium fluoride, or an organic base, such as triethylamine), a metal source (e.g. a palladium source such as Pd2(dba)3) and, optionally, a ligand for the metal (e.g. a phosphine ligand, such as X-Phos) in a suitable solvent (for example a single solvent, such as acetonitrile, or a mixed solvent system, such as a mixture of dimethoxyethane and water). The metal catalyst and ligands may also be added as a single, pre-formed, complex (e.g. a palladium/phosphine complex, such as palladium tetrakistriphenylphosphine, bis(triphenylphosphine)palladium dichloride or [1,1′-bis(diphenylphosphino)ferrocene]palladium dichloride).

Compounds of formula (AK) may be prepared from amidines of formula (J) and malonyl diesters of formula (AL)—reaction scheme 68.
Diesters of formula (A) are well known in the literature.
Compounds of formula (I) in which P is CH(CONHR′) may be prepared by the reaction of compounds of formula (H) with an amine of formula R5NH2, an aldehyde of formula Q-CHO and an isonitrile of formula R′NC.
Compounds of formula (I) in which m is 0 and n is 2 may be prepared by the reaction of compounds of formula (AM) with a reagent that can functionalise the double bond (reaction scheme 70).
For example, a compound of formula (I) in which the groups R′ are hydrogen may be prepared from a compound of formula (AM) by reaction with a suitable reducing agent, (e.g. hydrogen gas in the presence of a metal catalyst, such as palladium supported on carbon), reaction scheme 71.
As yet a further example, a compound of formula (I) in which R′ represents vicinal hydroxyl groups may be prepared from a compound of formula (AM) by reaction with a dihydroxylation reagent (e.g. osmium tetroxide), reaction scheme 72.
Compounds of formula (AM) may be prepared by the Heck reaction of compounds of formula (AF) with compounds of formula (AN) (see reaction scheme 73) in the presence of a suitable metal catalyst (e.g. a palladium species, such as palladium acetate) and a base (e.g. an organic base, such as triethylamine), in a suitable solvent.
Alternatively, compounds of formula (AM) may be prepared by the reaction of compounds of formula (I) in which Z is CHO under the conditions of a suitable olefination reaction (see reaction scheme 74), for example a Wittig, Horner-Emmons or Peterson reaction.
Compounds of formula (I) may be prepared from different compounds of formula (I) by the conversion of any of the substituents Y, Z, A, P, W and R5 or the ring Q into a different group Y, Z, A, P, W, R5 or Q using techniques well known to the skilled man.
For example, an unsaturated group A (e.g. an alkene or cycloalkene) may be reduced to form a saturated group (e.g. an alkyl or cycloalkyl group). When A is an unsaturated ring it may be oxidised to form an aromatic ring under standard conditions.
A further example is the conversion of a compound in which Y is a halogen or sulphonate (e.g. a bromine or chlorine atom) into a compound in which Y is a carbon-based group, e.g. an alkyl group or an optionally substituted phenyl or heteroaryl ring. Such a transformation may be carried out by reaction with a metal or metalloid derivative of the alkyl group or phenyl or heteroaryl ring (e.g. a boronic acid or boronate ester) in the presence of a base (e.g. an inorganic base, such as potassium phosphate or caesium fluoride, or an organic base, such as triethylamine), a metal source (e.g. a palladium source such as Pd2(dba)3) and, optionally, a ligand for the metal (e.g. a phosphine ligand, such as X-Phos) in a suitable solvent (e.g. a single solvent, such as acetonitrile, or a mixed solvent system, such as a mixture of dimethoxyethane and water). The metal catalyst and ligands may also be added as a single, pre-formed, complex (e.g. as a palladium/phosphine complex, such as palladium tetrakistriphenylphosphine, bis(triphenylphosphine)palladium dichloride or [1,1′-bis(diphenylphosphino)ferrocene]palladium dichloride).
A further compound of formula (I) may be prepared from a compound of formula (I), in which R5 is H by reaction with a suitable reagent R5-LG in which LG is a leaving group such as a halogen atom. Examples of such reagents R5-LG are alkyl halides and acid anhydrides. For example a compound of formula (I) in which R5 is COR may be prepared from a compound of formula (I) wherein R5 is hydrogen by reaction with an acylating agent such as an acyl chloride in the presence of a base (see reaction scheme 75).
In an additional example a compound of formula (I) in which V is a carboxylic acid may be prepared from a compound of formula (I) in which V is a carboxylate ester, by hydrolysis under basic or acidic conditions, for example by treatment with aqueous sodium hydroxide. Alternatively this transformation may be achieved by treatment of the ester with a nucleophile, e.g. an alkyl thiolate, in a suitable solvent (both shown schematically in reaction scheme 76 below).
A compound of formula (I) in which V is a carboxylate ester may be prepared directly from a compound of formula (I) in which V is a carboxylic acid by esterification under standard conditions, for example by treatment with an alcohol ROH and an acid catalyst (e.g., thionyl chloride). Alternatively, this transformation may be achieved by first preparing an activated derivative of the acid group, e.g. an acyl halide, followed by reaction with an alcohol.
Other derivatives of the acid group in compounds of formula (I) in which V is a carboxylic acid may be prepared by standard methods found in the literature. For example a compound of formula (I) in which V is an amide group may be prepared from a compound of formula (I) in which V is a carboxylic acid by treatment with a suitable coupling reagent (e.g. a carbodiimide such as dicyclohexylcarbodiimide) and an amine RR′NH, optionally with a additive (e.g. dimethylaminopyridine), in a suitable solvent (e.g. dimethylformamide). Alternatively, this transformation may be performed by first preparing an activated derivative of the carboxylic acid group (e.g. an acyl halide such as an acid chloride), and then treating the activated derivative with an amine R′2NH. Again, both transformations are shown schematically in reaction scheme 77 below.
A compound of formula (I) in which Z is CO2R may be prepared from a compound of formula (I) in which Z is CH(OR)2 by treatment with a suitable oxidising agent, e.g. N-bromosuccinimide or a persulphate salt, optionally in the presence of an acid such as sulphuric acid (see reaction scheme 78).
A compound of formula (I) wherein V is CHO may be prepared from a compound of formula (I) in which V is CO2R by treatment with a suitable reducing agent (e.g. a hydride reducing agent such as DIBAL-H), see reaction scheme 79.
A compound of formula (I) in which V is CO2H may be prepared from a compound of formula (I) in which V is CHO by treatment with a suitable oxidising agent (e.g. sodium hypochlorite), see reaction scheme 80.
A compound of formula (I) in which V is CHO may be prepared by the removal of a suitable aldehyde protecting group (APG) from a compound of formula (I) in which V is a protected aldehyde (reaction scheme 81). Some examples of such protecting groups are acetals, thioacetals or hydrazones.
For example, a compound of formula (I) in which V is CHO may be prepared from a compound of formula (I) in which the aldehyde protecting group is an acetal, e.g. a dialkyl acetal such as a diethyl acetal) by treatment with acid (e.g. an inorganic acid such as aqueous hydrochloric acid), shown schematically below.
A compound of formula (I) in which V is CHO may also be prepared from a compound of formula (I) in which V is CH2OH by oxidation under standard conditions, see reaction scheme 83, (e.g. using the Swern reaction).
An aldehyde of formula (I) in which V is CHO may be converted into a derivative (e.g. an acetal or dithioacetal) of formula (I) under conditions that are known in the literature.
A compound of formula (I) in which V is CH2OH may be prepared from a compound of formula (I) in which V is CHO by reaction with a suitable reducing agent (e.g. a metal hydride reducing agent, such as sodium borohydride), see reaction scheme 84.
Alternatively, a compound of formula (I) in which V is CH2OH may be prepared from a compound of formula (I) in which V is CO2R by treatment with a suitable reducing agent (e.g: a metal hydride reducing agent, such as lithium aluminium hydride), see reaction scheme 85.
A compound of formula (I) in which V is CH2OC(O)R may be prepared from a compound (I) in which V is CH2OH under standard conditions, for example by treatment with an acyl halide in the presence of a base (reaction scheme 86).
The skilled man will understand that transformations of this type may equally well be conducted at different stages of the synthetic route, for example converting one compound of formula (H) into a different compound of formula (H).
The skilled man will also understand that in certain instances more than one transformation can be conducted at one time utilising the same reaction conditions. For example a compound of formula (I) in which A and Y are the same may be prepared from a compound of formula (A1) (i.e. a compound of formula A in which Y is a leaving group such as a halogen atom or a sulphonate, which may be the same or different to LG) by reaction with an excess of a metal or metalloid derivative of A, such as a boronic acid, in the presence of a metal catalyst (e.g. a palladium derivative such as Pd2(dba)3), a ligand (e.g. a phosphine ligand such as X-Phos) and a base (such as potassium phosphate) in a suitable solvent (reaction scheme 87).
Another example is the preparation of a compound of formula (I) in which V is CONR5(PWQ) from a compound of formula (G1) (i.e. a compound of formula (G) in which V is CO2R) by treatment with an excess of an amine R5(QWP)NH in a suitable solvent (reaction scheme 88).
A further example (see reaction scheme 89) is the preparation of a compound of formula (H1) from a compound of formula (I2) by oxidation using a reagent that also provides a source of electropositive Y (e.g., N-bromosuccinimide for the case in which Y is Br).
One skilled in the art will realise that it is often possible to alter the order in which the transformations described above are conducted, or to combine them in alternative ways to prepare a wide range of compounds of formula (1). All such variations are contemplated within the scope of the invention.
The skilled man will also be aware that some reagents will be incompatible with certain values or combinations of the substituents Y, Z, A, P, W, Q, R5, R and R′ as defined herein, and any additional steps, such as protection and/or deprotection steps, which are necessary to achieve the desired transformation will be clear to the skilled man.
Compounds of formula (I) may be used in unmodified form, i.e. as obtainable from synthesis, but preferably are formulated in any suitable manner using formulation adjuvants, such as carriers, solvents and surface-active substances, for example, as described hereinafter.
The formulations can be in various physical forms, e.g. in the form of dusting powders, gels, wettable powders, water-dispersible granules, water-dispersible tablets, effervescent pellets, emulsifiable concentrates, microemulsifiable concentrates, oil-in-water emulsions, oil-flowables, aqueous dispersions, oily dispersions, suspo-emulsions, capsule suspensions, emulsifiable granules, soluble liquids, water-soluble concentrates (with water or a water-miscible organic solvent as carrier), impregnated polymer films or in other forms known e.g. from the Manual on Development and Use of FAO Specifications for Plant Protection Products, 5th Edition, 1999. The formulations can be in the form of concentrates which are diluted prior to use, although ready-to-use formulations can also be made. The dilutions can be made, for example, with water, liquid fertilisers, micronutrients, biological organisms, oil or solvents.
The formulations can be prepared e.g. by mixing the active ingredient with the formulation adjuvants in order to obtain compositions in the form of finely divided solids, granules, solutions, dispersions or emulsions. The active ingredients can also be formulated with other adjuvants, such as finely divided solids, mineral oils, oils of vegetable or animal origin, modified oils of vegetable or animal origin, organic solvents, water, surface-active substances or combinations thereof. The active ingredients can also be contained in very fine microcapsules consisting of a polymer. Microcapsules usually have a diameter of from 0.1 to 500 microns. Typically, they will contain active ingredients in an amount of about from 25 to 95% by weight of the capsule weight. The active ingredients can be in the form of a monolithic solid, in the form of fine particles in solid or liquid dispersion or in the form of a suitable solution. The encapsulating membranes comprise, for example, natural or synthetic rubbers, cellulose, styrene/butadiene copolymers, polyacrylonitrile, polyacrylate, polyesters, polyamides, polyureas, polyurethane or chemically modified polymers and starch xanthates or other known polymers. Alternatively, very fine microcapsules can be formed in which the active ingredient is contained in the form of finely divided particles in a solid matrix of base substance, but the microcapsules are not themselves encapsulated.
The formulation adjuvants that are suitable for the preparation of compositions according to the invention are known per se. As liquid carriers there may be used: water, toluene, xylene, petroleum ether, vegetable oils, acetone, methyl ethyl ketone, cyclohexanone, acid anhydrides, acetonitrile, acetophenone, amyl acetate, 2-butanone, butylene carbonate, chlorobenzene, cyclohexane, cyclohexanol, alkyl esters of acetic acid, diacetone alcohol, 1,2-dichloropropane, diethanolamine, p-diethylbenzene, diethylene glycol, diethylene glycol abietate, diethylene glycol butyl ether, diethylene glycol ethyl ether, diethylene glycol methyl ether, N,N-dimethylformamide, dimethyl sulfoxide, 1,4-dioxane, dipropylene glycol, dipropylene glycol methyl ether, dipropylene glycol dibenzoate, diproxitol, alkylpyrrolidone, ethyl acetate, 2-ethylhexanol, ethylene carbonate, 1,1,1-trichloroethane, 2-heptanone, alpha-pinene, d-limonene, ethyl lactate, ethylene glycol, ethylene glycol butyl ether, ethylene glycol methyl ether, gamma-butyrolactone, glycerol, glycerol acetate, glycerol diacetate, glycerol triacetate, hexadecane, hexylene glycol, isoamyl acetate, isobornyl acetate, isooctane, isophorone, isopropylbenzene, isopropyl myristate, lactic acid, laurylamine, mesityl oxide, methoxypropanol, methyl isoamyl ketone, methyl isobutyl ketone, methyl laurate, methyl octanoate, methyl oleate, methylene chloride, m-xylene, n-hexane, n-octylamine, octadecanoic acid, octylamine acetate, oleic acid, oleylamine, o-xylene, phenol, polyethylene glycol (PEG), propionic acid, propyl lactate, propylene carbonate, propylene glycol, propylene glycol methyl ether, p-xylene, toluene, triethyl phosphate, triethylene glycol, xylenesulfonic acid, paraffin, mineral oil, trichloroethylene, perchloroethylene, ethyl acetate, amyl acetate, butyl acetate, propylene glycol methyl ether, diethylene glycol methyl ether, methanol, ethanol, isopropanol, and alcohols of higher molecular weight, such as amyl alcohol, tetrahydrofurfuryl alcohol, hexanol, octanol, ethylene glycol, propylene glycol, glycerol, N-methyl-2-pyrrolidone and the like. Water is generally the carrier of choice for diluting the concentrates. Suitable solid carriers are, for example, talc, titanium dioxide, pyrophyllite clay, silica, attapulgite clay, kieselguhr, limestone, calcium carbonate, bentonite, calcium montmorillonite, cottonseed husks, wheat flour, soybean flour, pumice, wood flour, ground walnut shells, lignin and similar substances, as described, for example, in CFR 180.1001. (c) & (d).
A large number of surface-active substances may advantageously be used in the formulations, especially in those formulations designed to be diluted with a carrier prior to use. Surface-active substances may be anionic, cationic, non-ionic or polymeric and they can be used as emulsifiers, wetting agents or suspending agents or for other purposes. Typical surface-active substances include, for example, salts of alkyl sulfates, such as diethanolammonium lauryl sulfate; salts of alkylarylsulfonates, such as calcium dodecylbenzenesulfonate; alkylphenol/alkylene oxide addition products, such as nonylphenol ethoxylate; alcohol/alkylene oxide addition products, such as tridecylalcohol ethoxylate; soaps, such as sodium stearate; salts of alkylnaphthalenesulfonates, such as sodium dibutylnaphthalenesulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di(2-ethylhexyl)sulfosuccinate; sorbitol esters, such as sorbitol oleate; quaternary amines, such as lauryltrimethylammonium chloride, polyethylene glycol esters of fatty acids, such as polyethylene glycol stearate; block copolymers of ethylene oxide and propylene oxide; and salts of mono- and di-alkylphosphate esters; and also further substances described e.g. in “McCutcheon's Detergents and Emulsifiers Annual” MC Publishing Corp., Ridgewood N.J., 1981.
Further adjuvants that can usually be used in pesticidal formulations include crystallisation inhibitors, viscosity modifiers, suspending agents, dyes, anti-oxidants, foaming agents, light absorbers, mixing auxiliaries, antifoams, complexing agents, neutralising or pH-modifying substances and buffers, corrosion inhibitors, fragrances, wetting agents, take-up enhancers, micronutrients, plasticisers, glidants, lubricants, dispersants, thickeners, antifreezes, microbicides, and also liquid and solid fertilisers.
The compositions according to the invention can additionally include an additive comprising an oil of vegetable or animal origin, a mineral oil, alkyl esters of such oils or mixtures of such oils and oil derivatives. The amount of oil additive in the composition according to the invention is generally from 0.01 to 10%, based on the spray mixture. For example, the oil additive can be added to the spray tank in the desired concentration after the spray mixture has been prepared. Preferred oil additives comprise mineral oils or an oil of vegetable origin, for example rapeseed oil, olive oil or sunflower oil, emulsified vegetable oil, such as AMIGO® (Rhône-Poulenc Canada Inc.), alkyl esters of oils of vegetable origin, for example the methyl derivatives, or an oil of animal origin, such as fish oil or beef tallow. A preferred additive contains, for example, as active components essentially 80% by weight alkyl esters of fish oils and 15% by weight methylated rapeseed oil, and also 5% by weight of customary emulsifiers and pH modifiers. Especially preferred oil additives comprise alkyl esters of C8-22 fatty acids, especially the methyl derivatives of C12-18 fatty acids, for example the methyl esters of lauric acid, palmitic acid and oleic acid, being of importance. Those esters are known as methyl laurate (CAS-111-82-0), methyl palmitate (CAS-112-39-0) and methyl oleate (CAS-112-62-9). A preferred fatty acid methyl ester derivative is Emery® 2230 and 2231 (Cognis GmbH). Those and other oil derivatives are also known from the Compendium of Herbicide Adjuvants, 5th Edition, Southern Illinois University, 2000. Another preferred adjuvant is Adigor® (Syngenta AG) which is a methylated rapeseed oil-based adjuvant.
The application and action of the oil additives can be further improved by combination with surface-active substances, such as non-ionic, anionic or cationic surfactants. Examples of suitable anionic, non-ionic and cationic surfactants are listed on pages 7 and 8 of WO97/34485. Preferred surface-active substances are anionic surfactants of the dodecylbenzylsulfonate type, especially the calcium salts thereof, and also non-ionic surfactants of the fatty alcohol ethoxylate type. Special preference is given to ethoxylated C12-22 fatty alcohols having a degree of ethoxylation of from 5 to 40. Examples of commercially available surfactants are the Genapol types (Clariant AG). Also preferred are silicone surfactants, especially polyalkyl-oxide-modified heptamethyltriloxanes which are commercially available e.g. as Silwet L-77®, and also perfluorinated surfactants. The concentration of the surface-active substances in relation to the total additive is generally from 1 to 30% by weight. Examples of oil additives consisting of mixtures of oil or mineral oils or derivatives thereof with surfactants are Edenor ME SU®, Turbocharge® (Syngenta AG, CH) or ActipronC (BP Oil UK Limited, GB).
If desired, it is also possible for the mentioned surface-active substances to be used in the formulations on their own, that is to say without oil additives.
Furthermore, the addition of an organic solvent to the oil additive/surfactant mixture may contribute to an additional enhancement of action. Suitable solvents are, for example, Solvesso® (ESSO) or Aromatic Solvent® (Exxon Corporation). The concentration of such solvents can be from 10 to 80% by weight of the total weight. Oil additives that are present in admixture with solvents are described, for example, in U.S. Pat. No. 4,834,908. A commercially available oil additive disclosed therein is known by the name MERGE® (BASF Corporation). A further oil additive that is preferred according to the invention is SCORE® (Syngenta Crop Protection Canada).
In addition to the oil additives listed above, for the purpose of enhancing the action of the compositions according to the invention it is also possible for formulations of alkylpyrrolidones (e.g. Agrimax®) to be added to the spray mixture. Formulations of synthetic lattices, e.g. polyacrylamide, polyvinyl compounds or poly-1-p-menthene (e.g. Bond®, Courier® or Emerald®) may also be used. It is also possible for solutions that contain propionic acid, for example Eurogkem Pen-e-trate®, to be added to the spray mixture as action-enhancing agent.
Herbicidal compositions of the invention generally comprise from 0.1 to 99% by weight, especially from 0.1 to 95% by weight, compounds of formula (I) and from 1 to 99.9% by weight of a formulation adjuvant which preferably includes from 0 to 25% by weight of a surface-active substance. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations.
Examples of preferred formulation types and their typical compositions are given below (% is percent by weight). Wettable powders as described herein are one particularly preferred type of formulation for use in the invention. In other preferred embodiments, in particular where the compound/composition/formulation of the invention is intended for use on turf, granular (inert or fertiliser) formulations as described herein are particularly suitable.
The following Examples further illustrate, but do not limit, the invention.
Emulsions of any desired concentration can be obtained from such concentrates by dilution with water.
The solutions are suitable for use in the form of microdrops.
The active ingredient is mixed thoroughly with the adjuvants and the mixture is thoroughly ground in a suitable mill, affording wettable powders which can be diluted with water to give suspensions of any desired concentration.
The active ingredient is dissolved in methylene chloride and applied to the carrier by spraying, and the solvent is then evaporated off in vacuo.
The finely ground active ingredient is uniformly applied, in a mixer, to the carrier moistened with polyethylene glycol. Non-dusty coated granules are obtained in this manner.
The active ingredient is mixed and ground with the adjuvants, and the mixture is moistened with water. The mixture is extruded and then dried in a stream of air.
Ready-to-use dusts are obtained by mixing the active ingredient with the carriers and grinding the mixture in a suitable mill.
The finely ground active ingredient is intimately mixed with the adjuvants, giving a suspension concentrate from which suspensions of any desired concentration can be obtained by dilution with water.
Compounds of the invention (as well as mixtures and/or formulations containing the same) find utility as herbicides, and may thus be employed in methods of controlling plant growth. Such methods involve applying to the plants or to the locus thereof an herbicidally effective amount of said compound, or composition comprising the same (or mixture as described hereinafter). The invention thus also relates to a method of inhibiting plant growth which comprises applying to the plants or to the locus thereof a herbicidally effective amount of a compound of formula (I), composition, or mixture of the invention. In particular the invention provides a method of controlling weeds in crops of useful plants, which comprising applying to said weeds or the locus of said weeds, or to said crop of useful plants, a compound of formula I or a composition or mixture containing the same.
The term “locus” as used herein includes not only areas where weeds may already be growing, but also areas where weeds have yet to emerge, and also to areas under cultivation with respect to crops of useful plants. Areas under cultivation include land on which the crop plants are already growing and land intended for cultivation with such crop plants.
A compound, composition, and/or mixture of the invention may be used in a pre-emergence application and/or in a post-emergence application in order to mediate its effect.
Crops of useful plants in which compounds of formula (I), as well as formulations and/or mixtures containing the same, may be used according to the invention include perennial crops, such as citrus fruit, grapevines, nuts, oil palms, olives, pome fruit, stone fruit and rubber, and annual arable crops, such as cereals, for example barley and wheat, cotton, oilseed rape, maize, rice, soy beans, sugar beet, sugar cane, sunflowers, ornamentals and vegetables, especially cereals and maize.
Compounds of formula (I), formulations and/or mixtures containing the same may also be used on turf, pasture, rangeland, rights of way etc. In particular they may used on golf-courses, lawns, parks, sports-fields, race-courses and the like.
Crops are to be understood as also including those crops which have been rendered tolerant to herbicides or classes of herbicides (e.g. Auxines, ALS-, GS-, EPSPS-, PPO- and HPPD-inhibitors) by conventional methods of breeding or by genetic engineering. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding is Clearfield® summer rape (canola). Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®, as well as corn, soybean and cotton that have been engineered to be resistant to phenoxypropionic acids, pyridyloxyacetic acids and/or picolinate auxines.
Crops are also to be understood as being those which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and also Bt potatoes (resistant to Colorado beetle). Examples of Bt maize are the Bt 176 maize hybrids of NK® (Syngenta Seeds). The Bt toxin is a protein that is formed naturally by Bacillus thuringiensis soil bacteria. Examples of toxins, or transgenic plants able to synthesise such toxins, are described in EP-A-451 878, EP-A-374 753, WO 93/07278, WO 95/34656, WO 03/052073 and EP-A-427 529. Examples of transgenic plants comprising one or more genes that code for an insecticidal resistance and express one or more toxins are KnockOut® (maize), Yield Gard® (maize), NuCOTIN33B® (cotton), Bollgard® (cotton), NewLeaf® (potatoes), NatureGard® and Protexcta®. Plant crops or seed material thereof can be both resistant to herbicides and, at the same time, resistant to insect feeding (“stacked” transgenic events). For example, seed can have the ability to express an insecticidal Cry3 protein while at the same time being tolerant to glyphosate.
Crops are also to be understood as being those which are obtained by conventional methods of breeding or genetic engineering and contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavour).
The term “weeds” as used herein means any undesired plant, and thus includes not only agronomically important weeds as described below, but also volunteer crop plants.
Compounds of formula (I) may be used against a large number of agronomically important weeds. The weeds that may be controlled include both monocotyledonous and dicotyledonous weeds, such as, for example, Alisma spp, Leptochloa chinensis, Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum, Rottboellia, Cyperus and especially Cyperus iria, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola, Veronica, and Ischaemum spp.
The rates of application of compounds of formula (I) may vary within wide limits and depend on the nature of the soil, the method of application (pre- or post-emergence; seed dressing; application to the seed furrow; no tillage application etc.), the crop plant, or weed to be controlled, the prevailing climatic conditions, and other factors governed by the method of application, the time of application and the target crop. The compounds of formula I according to the invention are generally applied at a rate of from 10 to 2000 g/ha, especially from 50 to 1000 g/ha.
Any method of application to weeds/crop of useful plant, or locus thereof, which is routinely used in agriculture may be used, for example application by spray or broadcast method typically after suitable dilution of a compound of formula (I) (whether said compound is formulated and/or in combination with one or more further active ingredients and/or safeners, as described herein).
The compounds of formula (I) according to the invention can also be used in combination with other active ingredients, e.g. other herbicides, and/or insecticides, and/or acaricides, and/or nematocides, and/or molluscicides, and/or fungicides, and/or plant growth regulators. Such mixtures, and the use of such mixtures to control weeds and/or undesired plant growth form yet further aspects of the invention. For the avoidance of doubt, mixtures of invention also include mixtures of two or more different compounds of formula (I).
Where a compound of formula (I) is combined with at least one additional herbicide, the following mixtures of the compound of formula (I) are particularly preferred. Compound of formula (I)+acetochlor, compound of formula (I)+acifluorfen, compound of formula (I)+acifluorfen-sodium, compound of formula (I)+aclonifen, compound of formula (I)+acrolein, compound of
