[0075] In the definition of the compounds of general formula (I) and in all the structural formulae hereinafter, the professional terms used, whether alone or in a composite, represent the following substituents: alkyl groups having more than two carbon atoms can be straight or branched. Alkyl groups are, for example, C1alkyl - methyl; C2alkyl - ethyl; C3alkyl - propyl, such as n-propyl or isopropyl; C4alkyl - butyl, such as n-butyl, isobutyl, tert-butyl or 2-butyl; C5alkyl - pentyl, such as n-pentyl; C6alkyl - hexyl, such as n-hexyl, isohexyl and 1,3-dimethylbutyl. Similarly, alkenyl is, for example, ethenyl, allyl, 1-methylprop-2-en-1-yl, 2-methylprop-2-en-1-yl, but-2-en-1-yl, but-3-en-1-yl, 1-methylbut-3-en-1-yl and 1-methylbut-2-en-1-yl. Alkynyl is, for example, ethynyl, propargyl, but-2-yn-1-yl, but-3-yn-1-yl, 1-methylbut-3-yn-1-yl. Alkylene groups are, for example, -CH2-, -CH2CH2-, -CH(CH3)-, -C(CH3)2-, and the like. Multiple bonds can be in any position of each unsaturated group. Cycloalkyl is a carbocyclic saturated ring system having, for example, three to six carbon atoms, such as cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. Similarly, cycloalkenyl is a monocyclic alkenyl group having, for example, three to six carbon ring members, such as cyclopropenyl, cyclobutenyl, cyclopentenyl and cyclohexenyl, wherein the double bond can be in any position. Halogen is fluorine, chlorine, bromine or iodine.

[0076] Unless otherwise specifically indicated, the term "aryl" as used herein includes, but is not limited to, phenyl, naphthyl, The term "heterocyclyl" as used herein includes, but is not limited to, saturated or unsaturated non-aromatic cyclic groups The term "heterocyclyl" as used herein includes, but is not limited to, saturated or unsaturated non-aromatic cyclic groups

[0077] The term "optionally" or "optional" means that the subsequently described event or circumstance can or can not occur, and thus that the description includes instances where the event or circumstance occurs and instances where it does not. For example, the term "optionally substituted" means that the specified atom or group is either unsubstituted or substituted with one or more substituents. If a group is substituted with a group, this is to be understood as meaning that the group is substituted with one or more groups, which are the same or different, selected from those mentioned. Furthermore, the same or different substituents contained in the same or different substituents are each independently selected, which can be the same or different. This applies equally to ring systems formed from different atoms and units. At the same time, the scope of the claims is to exclude those compounds which are chemically unstable under standard conditions, as known to the person skilled in the art.

[0078] In addition, unless specifically limited otherwise, the term "substituted" as used herein means substituted with one, two, three, four, or five groups; groups not marked with a specific position of attachment (including cycloalkyl and the like) can be attached in any position, including to a C or N; and if it is substituted, the substituents can likewise be substituted in any position, as long as the rules of chemical bonding are followed.

[0079] The present application provides a substituted pyridine compound having a chiral center as shown in formula I' or a salt thereof, N-oxide:

[0080] wherein the definitions of substituents Q, L, X, Y1, Y2, M are as described above, and the carbon atom at the position C* is a chiral center (R or S configuration).

[0081] In one embodiment, it has a stereochemical purity of 60-100% (S), preferably 70-100% (S), more preferably 80-100% (S), further preferably 90-100% (S), and even further preferably 95-100% (S), based on the content of stereoisomers having R and S configurations at this position.

[0082] In another embodiment, it has a stereochemical purity of 60-100% (R), preferably 70-100% (R), more preferably 80-100% (R), further preferably 90-100% (R), and even further preferably 95-100% (R), based on the content of stereoisomers having R and S configurations at this position.

[0083] wherein the "stereochemical purity" refers to the amount of the stereoisomer described as a percentage of the total amount of stereoisomers having a chiral center that is generated.

[0084] In the present application, the stereochemical configuration at the position marked * in formula I is determined according to the Cahn-Ingold-Prelog system, however the subject matter of the present application also relates to all stereoisomers of other positions included in formula I, and mixtures thereof. Such compounds of formula I include, for example, one or more additional asymmetric carbon atoms or other double bonds not specifically indicated in formula I. It is to be understood that the present application includes pure isomers and mixtures thereof in varying degrees of enrichment of the pure isomers, provided that the stereochemical configuration is correct, and that possible stereoisomers, such as enantiomers, diastereomers, Z- and E-isomers, defined by the particular spatial order, are included in formula I and can be obtained in stereoisomerically pure form from mixtures of stereoisomers by conventional methods, or also by stereoselective reactions in combination with the use of stereochemically pure starting materials.

[0085] If various functional groups are present, the present application also includes any keto and enol tautomeric forms and mixtures and salts thereof.

[0086] The stereoisomers can be obtained from mixtures by optical resolution. Likewise, the stereoisomers can be prepared selectively by using stereoselective reactions and using optically active starting materials and / or auxiliaries. For optical resolution, it is generally possible to use conventional methods (cf. Textbooks of Stereochemistry), for example the following methods for the resolution of mixtures of diastereomers, for example physical methods such as crystallization, chromatography, in particular column chromatography and high-pressure liquid chromatography, distillation methods, if appropriate under reduced pressure, extraction and other methods, usually with chromatographic separation on chiral stationary phases, which make it possible to separate residual mixtures of enantiomers. Suitable for preparative amounts or for industrial scale are methods such as, for example, crystallization of diastereomeric salts, which can be obtained from the compounds using optically active acids and, if acidic groups are present, if appropriate using optically active bases.

[0087] The method for preparing the substituted pyridine compound or salt, N-oxide thereof, comprises the following steps:

[0088] (1) Compounds represented by general formula I are prepared by coupling reaction of compounds represented by general formula II and III, and the reaction equation is as follows:

[0119] The present application also relates to formulations comprising at least one compound of the formula I and to the use thereof as a pesticidal application form, such as drenches, drip and spray liquids, prepared therefrom. In certain cases, the application forms comprise further pesticides and / or adjuvants having an improved action, such as penetrants, for example vegetable oils (such as rapeseed oil, sunflower oil), mineral oils (such as paraffin oil), alkyl esters of vegetable fatty acids (such as rapeseed oil methyl ester or soybean oil methyl ester), or alkanol alkoxylates; and / or spreaders, for example alkylsilicones and / or salts (such as organic or inorganic ammonium or phosphonium salts, for example ammonium sulfate or di-ammonium hydrogenphosphate); and / or retention promoters, for example dioctyl sulfosuccinate or hydroxypropyl guar polymer; and / or wetters, for example glycerol; and / or fertilizers, for example ammonium-, potassium- or phosphorus-containing fertilizers.

[0120] The formulations which are customary are, for example, water-soluble liquids (SL), emulsifiable concentrates (EC), aqueous emulsions (EW), suspension concentrates (SC, SE, FS, OD), water-dispersible granules (WG), granules (GR) and capsule concentrates (CS); these and other possible formulation types are described, for example, by Crop Life International in the following publication: Pesticide Specifications, Manual on development and use of FAO and WHO specifications for pesticides, FAO Plant Production and Protection Papers - 173, developed by the Joint FAO / WHO Committee on Pesticide Specifications, 2004, ISBN: 9251048576. The formulations optionally comprise, in addition to the compound(s) of the formula I, further agrochemically active ingredients.

[0121] These are preferably formulations or application forms which comprise auxiliaries, such as extenders, solvents, spontaneity promoters, carriers, emulsifiers, dispersants, antifreeze agents, biocides, thickeners; and or other auxiliaries, such as adjuvants. In the present context, an adjuvant is a component which enhances the biological efficacy of the formulation, whereas the component itself does not have any biological efficacy. Examples of adjuvants are agents which promote retention, spreading, adhesion to the leaf surface or penetration.

[0122] The formulations are prepared in known manner, for example by mixing the compound of the formula I with auxiliaries, such as extenders, solvents and / or solid carriers and / or further auxiliaries such as surfactants. The formulations are prepared immediately before use or during use.

[0123] The adjuvants used can be substances suitable for imparting specific properties to the formulations of the compounds of the formula I or to the use forms prepared from these formulations, such as ready-to-use insecticides, such as spray liquors or seed dressing products, for example specific physical, technical and / or biological properties.

[0124] Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, such as those selected from the group consisting of aromatic or aliphatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzene), alcohols and polyols (which can also be optionally substituted, etherified and / or esterified), ketones (such as acetone, cyclohexanone), esters (including fatty and oil) and (poly)ethers, unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, sulfones and sulfoxides (such as dimethyl sulfoxide).

[0125] If the extender used is water, it is also possible to use, for example, organic solvents as cosolvents. Useful liquid solvents are mainly: aromatic compounds, such as xylene, toluene or alkylnaphthalenes; chlorinated aromatic and aliphatic hydrocarbons, such as chlorobenzene, chloroethylene or dichloromethane; aliphatic hydrocarbons, such as cyclohexane or paraffins, such as mineral oil fractions, mineral and vegetable oils; alcohols, such as butanol or glycol and ethers and esters thereof; ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone; strongly polar solvents, such as dimethylformamide, dimethylacetamide and dimethyl sulfoxide and water.

Examples of suitable solvents are aromatic hydrocarbons, such as xylene, toluene or alkylnaphthalenes; chlorinated aromatic or aliphatic hydrocarbons, such as chlorobenzene, chloroethylene, dichloromethane; aliphatic hydrocarbons, such as cyclohexane, paraffins, mineral oil fractions, mineral and vegetable oils; alcohols, such as methanol, ethanol, isopropanol, butanol or glycol and ethers and esters thereof; ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone; strongly polar solvents, such as dimethyl sulfoxide and water.

[0127] In principle, all suitable carriers can be used. Useful carriers include, inter alia, for example, ammonium salts and ground natural minerals such as kaolin, clay, talc, chalk, quartz, attapulgite, montmorillonite or diatomite; and ground synthetic materials, such as finely divided silica, alumina and natural or synthetic silicates, resins, waxes and / or solid fertilizers. Mixtures of such carriers can also be used. Useful carriers for granules include, for example, crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite; and synthetic granules of inorganic and organic powders; and granules of organic materials such as sawdust, paper, coir, corn cobs and tobacco stems.

[0128] Also liquid gaseous extenders or solvents can be used. Particularly suitable extenders or carriers are those which are gaseous at ambient temperature and atmospheric pressure, for example aerosol propellant gases such as halogenated hydrocarbons, and also butane, propane, nitrogen and carbon dioxide.

[0129] Examples of emulsifiers and / or foaming, dispersing or wetting agents, or mixtures of these surfactants, having ionic or non-ionic properties are salts of polyacrylic acids; salts of lignosulphonic acids; salts of phenolsulphonic acids or naphthalenesulphonic acids; polycondensates of ethylene oxide with fatty alcohols or fatty acids or fatty amines or substituted phenols, preferably alkylphenols or arylphenols; salts of sulphosuccinic esters; taurine derivatives, preferably alkyl taurates; phosphoric esters of polyethoxylated alcohols or phenols; fatty acid esters of polyols; and derivatives of compounds containing sulphates, sulphonates and phosphates, such as alkyl aryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, protein hydrolysates, lignosulphite waste liquors and methylcellulose. If one of the above compounds of the formula I and / or one of the above inert carriers is not water-soluble and application is to be carried out in water, the presence of a surfactant is advantageous.

[0130] Other auxiliaries which can be present in the formulations and in the use forms derived from them include colourants such as inorganic pigments, for example iron oxide, titanium oxide, Prussian Blue, and organic dyes such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and also nutrients and micronutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

[0131] The additional components can be stabilisers which improve chemical and / or physical stability, such as cold-stabilisers, preservatives, antioxidants, light stabilisers or other agents. Foaming and antifoaming agents can also be present.

[0132] Furthermore, the formulations and use forms derived from them can also comprise, as additional auxiliaries, sticking agents such as carboxymethylcellulose, and also natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyacrylic acid, or natural phospholipids, such as cephalins, lecithins and synthetic phospholipids. Further possible auxiliaries are mineral and vegetable oils.

[0133] Optionally, other auxiliaries can be present in the formulations and in the use forms derived from them. Examples of such additives include fragrances, protective colloids, binders, adhesives, thickeners, thixotropic agents, penetration agents, retention aids, stabilisers, sequestering and chelating agents, complexing agents, humectants and spreaders. In general, the compounds of the formula I can be combined with any solid or liquid additive which is customary for formulation purposes.

[0134] Useful retention promoters include all those substances which lower the kinetic surface tension, such as dioctyl sulfosuccinate; or all those substances which increase the viscoelasticity, such as hydroxypropyl guar polymers.

[0135] In the context of the present application, useful penetrants include all those substances which are typically used to enhance the penetration of active agrochemical ingredients into plants. In this context, penetrants are defined by their ability to penetrate the cuticle of the plant by the (usually aqueous) application liquid and / or by the spray coating, thereby increasing the mobility of the active ingredient in the cuticle. Examples include: alcohol alkoxylates, such as coconut fatty ethoxylate (10) or isotridecyl ethoxylate (12); fatty acid esters, such as rapeseed oil methyl ester or soybean oil methyl ester; fatty amine alkoxylates, such as tallow amine ethoxylate (15); or ammonium and / or phosphonium salts, such as ammonium sulfate or di-ammonium hydrogenphosphate.

[0136] The formulations preferably comprise from 0.00000001 to 98% by weight of the compound of formula I, more preferably from 0.01 to 95% by weight of the compound of formula I, most preferably from 0.5 to 90% by weight of the compound of formula I, based on the weight of the formulation.

[0137] The content of the compound of formula I in the use forms prepared from the formulations, especially the insecticides, can vary within wide ranges. The concentration of the compound of formula I in the use forms can generally be from 0.00000001 to 95% by weight of the compound of formula I, preferably from 0.00001 to 1% by weight, based on the weight of the use form. Application is carried out in the customary manner appropriate for the use form.

[0138] The compound of formula I can also be used in combination with one or more substances selected from the group consisting of suitable fungicides, bactericides, acaricides, molluscicides, nematicides, insecticides, microbicides, beneficial organisms, pesticides, fertilizers, bird repellents, phytotonics, sterilants, safeners, semiochemicals and / or plant growth regulators, in order to broaden the spectrum of action, for example, to prolong the duration of action, to increase the rate of action, to prevent repellence or to prevent the development of resistance. In addition, such active ingredient combinations can improve plant growth and / or tolerance to abiotic factors, such as high or low temperatures, drought or high water content or soil salinity. It is also possible to improve flowering and fruiting performance, to optimize germination capacity and root development, to facilitate harvesting and to increase yield, to influence ripening, to improve the quality and / or nutritional value of the harvested products, to prolong the storage period and / or to improve the processing properties of the harvested products.

[0139] In addition, the compounds of the formula I can be present in mixtures with other active ingredients or semiochemicals such as attractants and / or bird repellents and / or plant activators and / or growth regulators and / or fertilizers. Likewise, the compounds of the formula I can be used in the form of mixtures with agents for improving the properties of plants such as growth, yield and quality of the harvested material.

[0181] Plants and plant parts

[0182] All plants and plant parts can be treated in accordance with the application. Plants are to be understood as meaning all plants and plant populations such as wanted and unwanted wild plants or crop plants (including naturally occurring crop plants) such as cereals (wheat, rice, triticale, barley, rye, oats), maize, soya, potatoes, sugar beet, sugar cane, tomatoes, peas and other vegetable species, cotton, tobacco, rape and fruit plants (with the fruits mentioned: apples, pears, citrus fruits, and grapes). Crop plants can be plants which have been obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and plant cultivars which can be protected by the plant breeders' rights and which have been developed by plant breeding and selection or by biotechnological and genetic engineering methods. Plant parts are to be understood as meaning all parts and organs of the plants above and below ground such as shoot, leaf, flower and root, given as examples: leaves, needles, stems, trunks, flowers, fruit bodies, fruits and seeds, and also tubers. Plant parts also include harvested material and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, slips and seeds.

[0183] The treatment of plants and plant parts with the compounds of the formula I according to the application is carried out directly or by allowing the compounds to act on the surroundings, habitat or storage space of the plants, by methods of treatment which are customary therefor, such as, for example, the dipping, spraying, vaporizing, fogging, spreading-on, painting-on, injection and, in the case of propagation material, especially seeds, the application of one or more coats.

[0184] As mentioned above, all plants and their parts can be treated in accordance with the application. In a preferred embodiment, wild plants species and plant cultivars, or those obtained by conventional biological breeding methods such as crossing or protoplast fusion, and their parts are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (genetically modified organisms), and their parts are treated. The term "parts" or "plant parts" or "parts of plants" has been explained above. It is especially preferred to treat plants and plants parts of those plants which have been so far obtained by means of conventional breeding and propagation methods or those plants which are in use in the fields or plantations.

They include plants protected by plant breeders' rights and plants which are not protected by plant breeders' rights.

[0185] Transgenic plants, seed treatment and inteeration events

[0186] Preferred transgenic plants or plant cultivars (obtained through genetic engineering) treated according to the present invention include all plants that have undergone genetic modification and received genetic material that endows these plants with particularly advantageous and useful properties. Examples of such properties include: better plant growth, enhanced tolerance to high or low temperatures, enhanced tolerance to drought or to water levels or soil salinity, improved flowering performance, easier harvesting, accelerated maturation, higher yield, higher quality and / or higher nutritional value of the harvested product, longer shelf life and / or processability of the harvested product. Other, and particularly emphasized, examples of this property include enhanced plant resistance to animal and microbial pests, such as insects, arachnids, nematodes, mites, slugs, and snails, for example, due to toxins formed in the plant, particularly those formed in the plant through genetic material from Bacillus thuringiensis (e.g., through genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb, and CryIF and combinations thereof); enhanced plant resistance to plant pathogenic fungi, bacteria, and / or viruses, induced, for example, by systemically acquired resistance (SAR), systemins, phytoalexins, inducers, and resistance genes, as well as corresponding expressed proteins and toxins; and increased plant tolerance to specific active insecticidal ingredients, such as imidazolinones, sulfonylureas, glyphosate, or glufosinate (e.g., the "PAT" gene). Genes conferring the desired traits can exist in transgenic plants in a combined form. Examples of transgenic plants include important crop plants such as cereals (wheat, rice, triticale, barley, rye, oats), corn, soybeans, potatoes, sugar beets, sugarcane, tomatoes, peas and other types of vegetables, cotton, tobacco, rapeseed, and fruit plants (with fruits such as apples, pears, citrus fruits and grapes), with particular emphasis on corn, soybeans, wheat, rice, potatoes, cotton, sugarcane, tobacco, and rapeseed. A particularly emphasized trait is enhanced plant resistance to insects, arachnids, nematodes, slugs, and snails.

[0187] Crop protection – types of treatment

[0188] The treatment of plants and plant parts with the compounds of the formula I is carried out directly by the customary treatment methods, for example by immersing, spraying, atomizing, irrigating, evaporating, dusting, fogging, spreading, foaming, painting, spreading on, watering (drenching), drip irrigation, in the case of propagation material, especially in the case of seeds, also by dry seed treatment, wet seed treatment, treatment of the slurry, encrusting, coating with one or more coats, etc. It is also possible to apply the compounds of the formula I using the ultra-low-volume process or to inject them into the soil in the form of their use forms or of the compounds of the formula I themselves.

[0189] A preferred direct treatment of plants is the foliar application, which means that the compounds of the formula I are applied to the leaves, wherein the frequency of treatment and the rate of application are to be adjusted to the infestation level of the pests.

[0190] In the case of systemically active compounds, the compounds of the formula I can also enter the plant via the root system. The plant is then treated by acting on the habitat of the plant with the compounds of the formula I. This can be done, for example, by drenching; or by mixing into the soil or the nutrient solution, which means that the plant site, for example the soil or a hydroponic system, is flooded with the compounds of the formula I in liquid form; or by soil application, which means that the compounds of the formula I are introduced into the plant site in solid form, for example in the form of granules. In the case of rice crops, this can also be done by metering the compounds of the formula I in solid application form, for example as granules, into the flooded rice field.

[0191] Seed treatment

[0192] The control of animal pests by treatment of plant seeds has long been known and is the subject of constant improvements. Seed treatment, however, involves a series of problems which cannot always be solved in a satisfactory manner. There is therefore a need to develop methods for protecting seeds and germinating plants which do not require or at least significantly reduce the additional application of pesticides during storage, after sowing or after the emergence of the plants. There is also a need to optimize the amount of active ingredient used in order to provide the seeds and germinating plants with the best possible protection against attack by animal pests, without the active ingredient used impairing the plants themselves. In particular, the methods used for seed treatment should also take into account the intrinsic pesticidal and / or nematicidal properties of pest-resistant or pest-tolerant transgenic plants in order to achieve the best possible protection of the seeds and germinating plants with the least possible use of crop protection products.

[0193] Thus, more particularly, the present application also relates to a method for protecting seed and germinating plants from attack by pests by treating the seed with one of the compounds of formula I. The method of the present application for protecting seed and germinating plants from attack by pests also comprises a method wherein the seed is treated simultaneously with one of the compounds of formula I and a mixture partner in one operation or successively. It also comprises a method wherein the seed is treated with one of the compounds of formula I and a mixture partner at different times.

[0194] The present application also relates to the use of the compounds of formula I for treating seed to protect the seed and resulting plants from attack by animal pests.

[0195] The present application further relates to seed which has been treated with one of the compounds of formula I to protect it from attack by animal pests. The present application also relates to seed which has been treated simultaneously with one of the compounds of formula I and a mixture partner. The present application also relates to seed which has been treated with one of the compounds of formula I and a mixture partner at different times. In the case of seed which has been treated with one of the compounds of formula I and a mixture partner at different times, the individual components can be present in different layers of the seed. In this case, the layers comprising the compounds of formula I and the mixture partner can optionally be separated by intermediate layers. The present application also relates to seed, wherein one of the compounds of formula I and a mixture partner has been applied as part of a coating or other layer or in addition to a coating.

[0196] The present application also relates to seed which, after treatment with one of the compounds of formula I, is subjected to a film coating process to protect the seed from dust abrasion.

[0197] One of the advantages which exists when one of the compounds of formula I acts systemically is that the treatment of the seed protects not only the seed itself but also the plant which results from it (after emergence) from attack by animal pests. In this way, direct treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.

[0198] A further advantage is that treatment of the seed with one of the compounds of formula I can promote germination and emergence of the treated seed.

[0199] It is likewise considered advantageous that the compounds of formula I can also be used, inter alia, for transgenic seed.

[0200] The compounds of formula I can also be used in combination with signal technology components, as a result of which, for example, the colonization of symbionts, such as rhizobia, mycorrhiza and / or endophytic bacteria or fungi, is improved and / or nitrogen fixation is optimized.

[0201] The compounds of the formula I are suitable for protecting the seed of any plant variety used in agriculture, in a greenhouse, in forestry or in horticulture. More particularly, the seeds include the seeds of cereals (for example wheat, barley, rye, millet and oats), maize, cotton, soybeans, rice, potatoes, sunflowers, coffee beans, tobacco, oilseed rape, oilseed rape seeds, sugar beets (for example sugar beets and fodder beets), peanuts, vegetables (for example tomatoes, cucumbers, beans, cruciferous plants, onions, lettuce), fruit plants, turf plants and ornamental plants. Of particular importance is the treatment of the seeds of cereals (wheat, barley, rye, oats), maize, soybeans, cotton, oilseed rape, oilseed rape seeds and rice.

[0202] As mentioned above, the treatment of transgenic seeds with the compounds of the formula I is also of particular importance. The seeds include the seeds of plants which usually comprise a heterologous gene which comprises the expression of at least one polypeptide which has, in particular, insecticidal and / or nematicidal properties. The heterologous gene in the transgenic seeds can be derived from microorganisms such as Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter, Glomus or Gliocladium. The compositions according to the application are particularly suitable for the treatment of transgenic seeds which comprise at least one heterologous gene derived from Bacillus. The heterologous gene is more preferably derived from Bacillus thuringiensis.

[0203] In the context of the present application, the compounds of the formula I are applied to the seeds. The seeds are preferably treated in a state which is sufficiently stable so that no damage occurs during the treatment. In general, the seeds can be treated at any point in time between harvesting and sowing. Seeds which have been separated from the plants and which have been freed from the husks, hulls, stems, skins, hairs or pulp are generally used. For example, seeds which have been harvested, cleaned and dried to a moisture content which allows storage can be used. Alternatively, seeds which have been dried, for example, and then treated with water and then dried again (for example, drenching) can also be used.

[0204] In general, when treating the seeds, it must be ensured that the amount of the compounds of the formula I and / or other additives which are applied to the seeds is chosen so that the germination of the seeds is not impaired and the plants which grow from the seeds are not damaged. This must be ensured in particular in the case of active ingredients which can exhibit phytotoxic effects at certain application rates.

[0205] The compounds of the formula I are generally applied to the seeds in the form of suitable formulations. Suitable formulations and seed treatment methods are known to the person skilled in the art.

[0206] The compounds of the formula I can be converted into customary seed-dressing preparations, such as solutions, emulsions, suspensions, dusts, foams, slurries or other coating compositions for seeds, and also ULV formulations.

[0207] These formulations are prepared in known manner, by mixing the compounds of the formula I with customary additives, such as customary extenders and solvents or diluents, colorants, wetting agents, dispersants, emulsifiers, foaming agents, preservatives, secondary thickeners, stickers, gibberellins and also water.

[0208] Useful colorants which can be present in the seed-dressing preparations used according to the application are all colorants which are customary for this purpose. It is possible to use sparingly water-soluble pigments or it is possible to use water-soluble dyes. Examples include the known colorants known as Rhodamine B, C.I. Pigment Red 112 and C.I. Solvent Red 1.

[0209] Useful wetting agents which can be present in the seed-dressing preparations used according to the application are all substances which promote wetting and which are customary for the formulation of active agricultural-chemical ingredients. Preference is given to using alkyl naphthalene sulfonates, such as diisopropyl naphthalene sulfonate or diisobutyl naphthalene sulfonate.

[0210] Useful dispersants and / or emulsifiers which can be present in the seed-dressing preparations used according to the application are all non-ionic, anionic and cationic dispersants which are customary for the formulation of active agricultural-chemical ingredients. Preference is given to using non-ionic or anionic dispersants or mixtures of non-ionic or anionic dispersants. Suitable non-ionic dispersants include, in particular, ethylene oxide / propylene oxide block copolymers, alkylphenol polyglycol ethers and tristyrylphenol polyglycol ethers, and also phosphated or sulfated derivatives thereof. Suitable anionic dispersants are, inter alia, lignosulfonates, polyacrylic acid salts and condensates of arylsulfonic acids / formaldehyde.

[0211] Antifoams which can be present in the seed-dressing preparations used according to the application are all foam inhibitors which are customary for the formulation of active agricultural-chemical ingredients. Preference is given to using silicone antifoams and magnesium stearate.

[0212] Preservatives which can be present in the seed-dressing preparations used according to the application are all substances which can be used for this purpose in agrochemical compositions. Examples include dichlorophen and benzyl alcohol hemiformal.

[0213] Secondary thickeners which can be present in the seed-dressing preparations used according to the application are all substances which can be used for this purpose in active agrochemical compositions. Preferred examples include cellulose derivatives, acrylic acid derivatives, xanthan gum, modified clays and finely divided silicas.

[0214] Useful binders which can be present in the seed dressing preparations used according to the application are all customary binders which can be used in seed dressing products. Preferred examples include polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and tylose.

[0215] The gibberellins which can be present in the seed dressing preparations used according to the application are preferably gibberellin A1, A3 (= gibberellic acid), A4 and A7, particularly preferred use being made of gibberellic acid.

[0216] The seed dressing preparations used according to the application can be used to treat a large number of different kinds of seed, either directly or after prior dilution with water. For example, the concentrates or the preparations obtainable therefrom by dilution with water can be used to coat the seeds of cereals (such as wheat, barley, rye, oats and triticale), and also the seeds of maize, rice, oilseed rape, peas, beans, cotton, sunflower, soybean and sugar beet, or a large number of different vegetable seeds. The seed dressing preparations used according to the application or their dilution forms used can also be used to dress the seeds of transgenic plants.

[0217] For the treatment of the seed with the seed dressing preparations used according to the application or the use forms prepared therefrom, all mixing apparatuses which are customary for seed dressing are available. More particularly, the process for seed dressing is as follows: the seeds are placed in batches or continuously in a mixer; the particular required amount of seed dressing preparation, either as such or after prior dilution with water, is added; and mixing is carried out until the preparation is uniformly distributed over the seeds. If appropriate, a drying operation can be carried out subsequently.

[0218] The application rates of the seed dressing preparations used according to the application can vary within a relatively wide range. They depend on the particular content of compounds of the formula I in the preparation and on the seeds. The application rates of the compounds of the formula I are generally from 0.001 g to 50 g per kg of seeds; preferably from 0.01 g to 15 g per kg of seeds.

[0219] For animal health

[0220] In the field of animal health, i.e. veterinary medicine, the active ingredients according to the application are used against animal parasites, especially ectoparasites or, in other embodiments, endoparasites. The term "endoparasites" includes, inter alia, helminths, such as tapeworms, roundworms or flukes; and protozoa, such as coccidia. Ectoparasites are generally and preferably arthropods, especially insects, such as biting and sucking flies, parasitic fly larvae, lice, hair lice, bird lice, fleas and the like; or mites, such as hard ticks or soft ticks; or mites, such as Demodex mites, autumn mites and bird mites and the like; and aquatic ectoparasites, such as copepods.

[0221] In the field of veterinary medicine, compounds of formula I which have a good homeotherm toxicity are suitable for controlling parasites which occur in animal breeding and animal keeping in livestock, breeding animals, zoo animals, laboratory animals, experimental animals and domestic animals. They are effective against all or specific developmental stages of the parasites.

[0222] Agricultural livestock includes, for example, mammals such as sheep, goats, horses, donkeys, camels, water buffalo, rabbits, reindeer, fallow deer, and in particular cattle and swine; poultry such as turkeys, ducks, geese, and in particular chickens; fish and crustaceans, for example in aquaculture; and insects such as bees.

[0223] Domestic animals include, for example, mammals such as hamsters, guinea pigs, rats, mice, chinchillas, ferrets, in particular dogs, cats, caged birds, reptiles, amphibians and ornamental fish.

[0224] In a preferred embodiment, the compounds of formula I are administered to mammals.

[0225] In another preferred embodiment, the compounds of formula I are administered to avians, i.e. caged birds and in particular poultry.

[0226] The use of the compounds of formula I to control animal parasites is intended to reduce or prevent the cases of disease, death and performance reduction (in the case of meat, milk, wool, rawhide, eggs, honey, etc.) so that animal keeping can be more economical and simple and better keeping of the animals in good condition is achieved.

[0227] In the field of animal health, the term "control" or "controlling" means that the compounds of formula I are effective in reducing the incidence of a particular parasite to a non-damaging extent in animals infected with such parasites. More specifically, in the present context, "control" means that the compounds of formula I are able to kill, inhibit the growth of or inhibit the multiplication of the respective parasites.

[0228] In general, the active ingredients of the present application can be used as such for treating animals. It is preferred to use them in the form of pharmaceutical compositions which can contain pharmaceutically acceptable excipients and / or adjuvants known in the art (administration).

[0229] In the field of animal health and in animal husbandry, the active ingredients are used (administered) in the known manner, for example enterally, in the form of tablets, capsules, potions, drenches, granules, pastes, boluses, feed-through processes and suppositories; parenterally, for example by injection (intramuscularly, subcutaneously, intravenously, in particular intraperitoneally), by implantation; nasally; dermally, for example in the form of dips or baths, sprays, pour- ons and spot- ons, washes and dusts; and by means of mouldings comprising the active ingredients, for example collars, earmarks, tailmarks, limb bands, halters, marking devices and the like. The active ingredients can be formulated as shampoos or as suitable formulations which can be applied in the form of aerosols or non-pressurised spray agents such as pump sprays and atomised sprays.

[0230] In the case of use on livestock, poultry, domestic pets and the like, the active ingredients of the application can be used in the form of formulations (for example dusts, wettable powders ["WP"], emulsions, emulsifiable concentrates ["EC"], flowable compositions, uniform solutions and suspensions ["SC"], containing from 1% to 80% by weight of active ingredient, either directly or after dilution (for example from 100-fold to 10 000-fold), or they can be used as chemical baths.

[0231] In the case of use in the field of animal health, in order to broaden the spectrum of activity, the active ingredients of the application can be used in combination with suitable synergists, repellents or other active ingredients, for example acaricides, insecticides, anthelmintics, antiprotozoans.

[0232] Vector control

[0233] The compounds of the formula I are also useful in vector control. In the context of the present application, a vector is an arthropod, in particular an insect or an arachnid, which is capable of transmitting a pathogen, for example a virus, a helminth, a unicellular organism and a bacterium, from a reservoir (plant, animal, human being or the like) to a host. The pathogen can be transmitted to the host mechanically (for example non-stinging flies with trachoma) or can be transmitted to the host after injection (for example malaria parasites of mosquitoes).

[0234] In the context of the present application, examples of vectors are insects, for example aphids, flies, leafhoppers or thrips, which can transmit plant viruses to plants. Other carriers capable of transmitting plant viruses are spider mites, lice, beetles and nematodes.

[0235] In the context of the present application, further examples of vectors are insects and arachnids, such as mosquitoes, especially mosquitoes of the genus Aedes, Anopheles, for example A. gambiae, A. arabiensis, A. funestus, A. dirus (malaria); and mosquitoes of the genus Culex, ticks, fleas, flies, mites and ticks, which can transmit pathogens to animals and / or humans.

[0236] If the compounds of the formula I are resistant to destruction, then vector control is also possible.

[0237] The compounds of the formula I are suitable for the prevention of diseases and / or pathogens which are transmitted by vectors.

[0239] The compounds of the formula I are suitable for protecting industrial materials against attack or damage by insects, for example insects from the orders Coleoptera, Hymenoptera, Isoptera, Lepidoptera, Psocoptera and Zygentoma.

[0240] In the present context, industrial materials are to be understood as meaning inanimate materials, for example, preferably plastics, adhesives, sizes, paper and paperboard, leather, wood and worked wood products and coating compositions. Particularly preferred is the use of the application for the protection of wood.

[0241] In a further embodiment, the compounds of the formula I are used together with at least one further insecticide and / or at least one fungicide.

[0242] In a further embodiment, the compounds of the formula I are ready-to-use insecticides, meaning that they can be applied to the materials without further modification. In particular, suitable further insecticides or fungicides are those mentioned above.

[0243] Surprisingly, it has also been found that the compounds of the formula I can be used for protecting objects which come into contact with salt water or slightly brackish water from fouling, especially ship hulls, screens, nets, buildings, mooring equipment and signalling systems.
