EP-A-0 347 488, EP-A-0 372 263, EP-A-0 426 948, EP-A-0 434 940 and EP-A-0 492 171 propose cyanophenylpyrrole derivatives as acaricidal and insecticidal active ingredients in pesticides. However, the biological properties of the compounds described in these publications are not entirely satisfactory in the pest control sector, and this is why it has been found necessary to provide other compounds having pest-controlling properties, in particular for the control of insects and of representatives from the order of the Acarina, and this object is achieved according to the invention by providing the present compounds I which, surprisingly, are additionally also suitable for controlling phytopathogenic fungi.
Compounds I which have at least one basic centre can form for example acid addition salts. These acid addition salts are formed, for example, with strong inorganic acids such as mineral acids, for example perchloric acid, sulfuric acid, nitric acid, nitrous acid, a phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, for example unsubstituted or halogen-substituted CI-C 4 alkanecarboxylic acids, for example acetic acid, or unsaturated or saturated dicarboxylic acids, for example oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid or phthalic acid, or hydroxycarboxylic acids, for example ascorbic acid, lactic acid, malic acid, tartaric acid or citric acid, or benzoic acid, or with organic sulfonic acids for example C 1
-C
4 alkane- or arylsulfonic acids which are unsubstituted or substituted for example by halogen, for example methane- or Sp-toluenesulfonic acid. Furthermore, compounds I having at least one acidic group can form salts with bases. Suitable salts with bases are, for example, metal salts such as alkali metal salts or alkaline earth metal salts, for example sodium salts, potassium salts or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, for example ethyl-, diethyl-, triethyl-, or dimethylpropylamine, or a mono-, di- or trihydroxy lower-alkylamine, for i* example mono-, di- or triethanolamine. Furthermore, corresponding internal salts may possibly be formed. Preferred within the scope of the invention are agrochemically advantageous salts; however, the invention also comprises salts which are disadvantageous for agrochemical purposes, for example salts which are toxic to bees or fish and which are employed, for example, for the isolation or purification of free compounds I or their agrochemically usable salts. Due to the close relation between the compounds I in free form and in the form of their salts, the free compounds I, or salts thereof, which are mentioned hereinbefore and hereinafter are also to be understood as meaning analogously and expediently, where appropriate, the corresponding salts, or the free compounds I, respectively.
Unless otherwise defined, the general terms used hereinbefore and hereinafter have the meanings listed hereinafter.
Halogen as a group per se and as structural element of other groups and compounds such as haloalkyl, haloalkenyl, haloalkoxy, haloalkylthio, haloalkanesulfinyl and haloalkanesulfonyl is fluorine, chlorine, bromine or iodine, in particular fluorine, chlorine or bromine, especially fluorine or chlorine, in particular fluorine. Halogen R 2 is especially chlorine or bromine, in particular bromine.
Carbon-containing groups and compounds contain, unless otherwise defined, in each case 1 up to and including 9, preferably 1 up to and including 6 but 1 up to and including 4 being preferred, in particular 1 or 2, carbon atoms.
Alkyl as a group per se and as structural element of other groups and compounds such as haloalkyl, alkoxy, alkoxyalkoxy, haloalkoxy, alkylthio, haloalkylthio, alkanesulfinyl, .haloalkanesulfinyl, alkanesulfonyl, haloalkanesulfonyl, dialkylaminosulfonyl, dialkylaminocarbonyl, alkylcarbonyl, alkoxycarbonyl and alkylcarbonyloxy is either straight-chain, i.e. methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl or nonyl, or S branched, for example isopropyl, isobutyl, sec-butyl, tert-butyl, isopentyl, neopentyl or isooctyl, in each case with due consideration of the number of carbon atoms contained in each individual case in the particular group or compound.
Alkenyl, haloalkenyl, alkenylcarbonyloxy and alkynyl are straight-chain or branched and contain in each case two or, preferably, one unsaturated carbon bond(s). The double bonds or triple bonds of these substituents are separated from the remainder of the compound I, preferably by at least one saturated carbon atom. The following may be mentioned by way of example: allyl, methallyl, but-2-enyl, but-3-enyl, allylcarbonyloxy, propargyl, but-2-ynyl and but-3-ynyl.
Halogen-substituted carbon-containing groups and compounds such as haloalkyl, haloalkenyl, haloalkoxy, haloalkylthio, haloalkanesulfinyl and haloalkanesulfonyl can be partially halogenated or perhalogenated, where, in the case of multiple halogenation, the -4halogen substituents can be identical or different. Examples of haloalkyl as a group per se and as structural element of other groups and compounds such as haloalkyl, haloalkoxy, haloalkylthio, haloalkanesulfinyl and haloalkanesulfonyl are methyl, mono- to trisubstituted by fluorine, chlorine and/or bromine, such as CHF 2 or CF 3 ethyl, mono- to pentasubstituted by fluorine, chlorine and/or bromine, such as CH 2

A compound I, II or VII which can be obtained according to the process or by a different route can be converted into a different compound I, II or VII in a manner known per se by replacing one or more substituents of the starting compound I, II or VII in the customary manner by (an)other substituent(s) according to the invention.
.0 For example, hydroxyl groups (as substituents of alkyl groups R 4 can be alkylated to give alkoxy groups (as substituents of alkyl groups R 4 halogen R 3 can be introduced into unsubstituted positions of the phenyl ring; mercapto groups R 3 and/or R 4 can be oxidised to give sulfinyl or sulfonyl groups R 3 and/or R 4 or sulfinyl groups R 3 and/or R 4 can be oxidised to give sulfonyl groups R 3 and/or R 4 methyl groups R 4 can be mono-halogenated to give mono-halomethyl groups R 4 or the halogen substituent present in mono-halomethyl groups R 4 can be replaced by an alkoxy group to give a mono-alkoxymethyl group R 4 Depending on the choice of the reaction conditions and starting materials which are suitable in each case, it is possible to replace, in one reaction step, only one substituent by a different substituent according to the invention, or a plurality of substituents can be replaced by other substituents according to the invention in the same reaction step.
Salts of compounds I, II or VII can be prepared in a manner known per se. For example, acid addition salts of compounds I, II or VII are obtained by treatment with a suitable acid or a suitable ion-exchanger reagent, and salts with bases are obtained by treatment with a suitable base or a suitable ion-exchanger reagent.
Salts of compounds I, II or VII can be converted in the customary manner into the free compounds I, II or VII, respectively, for example acid addition salts by treatment with a suitable basic agent or a suitable ion-exchanger reagent and salts with bases for example S by treatment with a suitable acid or a suitable ion-exchanger reagent.
SSalts of compounds I, II or VII can be converted into other salts of compounds I, II or VII, respectively, in a manner known per se, for example acid addition salts into different acid addition salts, for example by treatment of a salt of an inorganic acid such as a hydrochloride with a suitable metal salt such as a sodium salt, barium salt or silver salt, of an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt which forms, for example silver chloride, is insoluble and so precipitates from the reaction mixture.
Depending on the procedure or reaction conditions, the compounds I, II or VII which have salt-forming properties can be obtained in free form or in the form of salts.
The compounds I, II or VII, in free form or in salt form, can exist in the form of one of the isomers which are possible or as a mixture thereof, for example as pure isomers, such as antipodes and/or diastereomers, or as isomer mixtures such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures, depending, for example, on the number, absolute and relative configuration of asymmetric carbon atoms in the -16molecule and/or depending on the configuration of non-aromatic double bonds in the molecule; the invention relates to the pure isomers as well as to all isomer mixtures which are possible and is to be understood accordingly hereinbefore and hereinafter, even when stereochemical details are not mentioned specifically in each case.
Diastereomer mixtures and racemate mixtures of compounds I, II or VII, in free form or in salt form, which can be obtained according to the process depending on the choice of starting materials and procedures or by other routes can be resolved in the known manner based on the physicochemical differences of the components to give the pure diastereomers or racemates, for example by fractional crystallisation, distillation and/or chromatography.
Enantiomer mixtures such as racemates which can be obtained accordingly can be resolved by known methods to give the optical antipodes, for example by recrystallisation from an optically active solvent, by chromatography on chiral adsorbents, for example high-pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable microorganisms, by cleavage with specific immobilised enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, where only one enantiomer Sis sequestered, or by conversion into diastereomeric salts, for example by reacting a basic end product racemate with an optically active acid such as carboxylic acid, for example camphoric acid, tartaric acid or malic acid, or sulfonic acid, for example camphorsulfonic acid, and resolution of the resulting diastereomer mixture, for example on the basis of their different solubilities by fractional crystallisation to give the diastereomers from S..0 which the enantiomer desired can be liberated by the action of suitable agents, for example basic agents.
In addition to the resolution of corresponding isomer mixtures, pure diastereomers, or enantiomers, can also be obtained according to the invention by generally known methods of diastereoselective, or enantioselective, synthesis, for example by carrying out the process according to the invention with educts having a suitable stereochemistry.
It is advantageous to isolate, or synthesise, in each case the biologically more active isomer, for example enantiomer or diastereomer, or isomer mixture, for example enantiomer mixture or diastereomer mixture, if the individual components have different biological activities.
-17- The compounds I, II or VII, in free form or in salt form, can also be obtained in the form of their hydrates and/or can include other solvents, for example those which can be used for the crystallisation of compounds in solid form.
The invention relates to all those embodiments of the process in which a compound which can be obtained in any step of the process is used as starting material or intermediate and all, or some, of the missing steps are carried out, or in which a starting material in the form of a derivative or salt and/or racemates or antipodes thereof are used or, in particular, formed under the reaction conditions.

The active ingredient in these compositions is employed as pure active ingredient, for example a solid active ingredient in a specific particle size, or, preferably, together with at least one of the auxiliaries conventionally used in the art of formulation, such as extenders, for example solvents or solid carriers, or surface-active compounds (surfactants).
The following are possible as solvents: aromatic hydrocarbons which may be partially hydrogenated, preferably the fractions C 8 to C 12 of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalenes, aliphatic or cycloaliphatic hydrocarbons such as paraffins or cyclohexane, alcohols such as ethanol, propanol or butanol, glycols as well as their ethers and esters such as propylene glycol, dipropylene S. glycol ether, ethylene glycol or ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents such as N-methyl-pyrrolid-2-one, dimethyl sulfoxide or N,N-dimethylformamide, water, unepoxidised or epoxidised vegetable oils such as unepoxidised or epoxidised rapeseed oil, castor oil, coconut oil or soya oil, and silicone oils.

Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants or surfactant mixtures having good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient to be formulated. The surfactants listed below are only exemplary; a large number of other surfactants which are customarily used in the art of the formulation and suitable according to the invention are described in the specialist literature.
Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols.
Other suitable non-ionic surfactants are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The ,.ompounds mentioned generally contain 1 to 5 ethylene glycol units per propylene glycol unit.
Examples which may be mentioned are nonylphenol polyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other suitable substances are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.
The cationic surfactants are mainly quaternary ammonium salts which contain at least one alkyl radical having 8 to 22 C atoms as substituents and which have lower halogenated or free alkyl, benzyl or lower hydroxyalkyl radicals as further substituents. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples which may be mentioned are stearyltrimethylammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide.
Suitable anionic surfactants can be either water-soluble soaps or water-soluble synthetic -23surface-active compounds. Suitable soaps which may be mentioned are the alkali metal salts, alkaline earth metal salts and substituted or unsubstituted ammonium salts of higher fatty acids (C 10
-C
22 such as the sodium salts or potassium salts of oleic or stearic acid or of natural mixtures of fatty acids which can be obtained, for example, from coconut oil or tallow oil; fatty acid methyltaurides may furthermore be mentioned. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. The fatty sulfonates and fatty sulfates are generally in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and generally have an alkyl radical having 8 to 22 C atoms, alkyl also embracing the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium or the calcium salt of ligninsulfonic acid, of the dodecylsulfuric acid ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of t- sulfuric acid esters and sulfonic acids of S fatty alcohol/ethylene oxide adducts. The sufonated benzimidazole derivatives preferably contain 2 sulfonyl groups and one fatty acid radical having 8 to 22 C atoms. Examples of alkylaryl sulfonates are the sodium, calcium or triethanolammonium salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensation product. Other suitable compounds are corresponding phosphates, for example salts of the phosphoric acid ester of a p-nonylphenol/(4-14)ethylene oxide adduct, or phospholipids.
As a lt:, the compositions comprise 0.1 to 99%, in particular 0.1 to 95 of active ingredient and 1 to 99.9 in particular 5 to 99.9 of at least one solid or liquid auxiliary, where, as a rule, 0 to 25 in particular 0.1 to 20 of the composition can be S surfactants is in each case to be understood as meaning per cent by weight). While concentrated compositions are more preferred as commercially available goods, the end consumer generally uses dilute compositions which have considerably lower concentrations of active ingredient. In particular, preferred compositions are composed as follows per cent by weight): Emulsifiable concentrates: Active ingredient: 1 to 90 preferably 5 to 20 Surfactant: 1 to 30 preferably 10 to Solvent: 5 to 98 preferably 70 to 85 -24- Dusts: Active ingredient: Solid carrier: Suspension concentrates: Active ingredient: Water: Surfactant: Wettable powders: Active ingredient: Surfactant: Solid carrier: Granules: Active ingredient: Solid carrier: 0.1 to 10 99.9 to 90 5 to75%, 94 to 24%, 1 to 40%, 0.5 to 90 0.5 to 20 5 to 99%, 0.5 to 30 99.5 to 70 preferably 0.1 to 1 preferably 99.9 to 99 preferably 10 to 50 preferably 88 to 30 preferably 2 to 30 preferably 1 to 80 preferably 1 to 15 preferably 15 to 98 preferably 3 to 15 preferably 97 to 85 r o *e The activity of the compositions according to the invention can be broadened considerably and adapted to prevailing circumstances by adding other insecticidal, acaricidal and/or fungicidal active ingredients. Suitable examples of active ingredients which are added are representatives of the following classes of active ingredients: organophosphorus compounds, nitrophenols and derivatives, formamidines, ureas, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis preparations. The compositions according to the invention can also comprise further solid or liquid auxiliaries, such as stabilisers, for example epoxidised or unepoxidised vegetable oils (for example epoxidised coconut oil, rapeseed oil or soya oil), defoamers, for example silicone oil, preservatives, viscosity regulators, binders and/or adhesives, and also fertilisers or other active ingredients for achieving specific effects, for example bactericides, nematicides, molluscicides or selective herbicides.
The compositions according to the invention are prepared in a manner known per se, for example in the absence of auxiliaries by grinding and/or screening of a solid active ingredient, or mixture of active ingredients, for example to obtain a certain particle size, and in the presence of at least one auxiliary for example by intimately mixing and/or grinding the active ingredient, or mixture of active ingredients, with the auxiliary(ies).
These processes for the preparation of the compositions according to the invention and the use of the compounds I for the preparation of these compositions are also part of the invention.
The invention furthermore relates to the methods by which the compositions are applied, i.e. the methods for controlling pests of the abovementioned type, such as spraying, atomising, dusting, brushing on, dressing, scattering or pouring, to be selected depending on the intended aims and the prevailing circumstances, and to the use of the compositions for controlling pests of the abovementioned type. Typical application concentrations are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The application rates per hectare are generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 20 to 600 g/ha.
A preferred application method in the field of crop protection is application to the foliage of the plants (foliar application), where the frequency of application and the dosage rate can be adjusted as a function of the severity of infestation with the pest in question.
Alternatively, the active ingredient can reach the plants via the root system (systemic action), by allowing the locus of the plants to absorb a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example the soil, such as in the form of granules (soil application). In the case of paddy rice, such granules can be metered into the flooded paddy field.
The compositions according to the invention are also suitable for protecting plant propagation material, for example seeds, such as fruits, tubers or grains, or plant cuttings, S against fungal infections and animal pests. The propagation material can be treated with the composition before use, for example seed can be dressed before sowing. The active ingredients according to the invention can also be applied to seed kernels (coating) either by immersing the kernels in a liquid composition or by coating them with a solid composition. It is also possible to apply the composition to the site where the propagation material is used, for example during sowing into the seed furrow. The invention also relates to these treatment methods for plant propagation material and to the plant propagation material which has been treated in this manner.
The following examples are intended to illustrate the invention. They impose no limitation on the invention. Temperatures are given in degrees centigrade.
