The invention relates to heteroaryldihydropyridine derivatives, to agrochemically active salts thereof, to use thereof and to methods and compositions for controlling phytopathogenic harmful fungi in and/or on plants or in and/or on seed of plants, to processes for producing such compositions and treated seed, and to use thereof for controlling phytopathogenic harmful fungi in agriculture, horticulture and forestry, in animal health, in the protection of materials and in the domestic and hygiene sector. The present invention further relates to a process for preparing heteroaryldihydropyridine derivatives.

It is already known that particular heterocyclically substituted thiazoles can be used as fungicidal crop protection compositions (see WO 07/014290, WO 08/013925, WO 08/013622, WO 08/091594, WO 08/091580, WO 09/055514, WO 09/094407, WO 09/094445, WO 09/132785, WO 10/037479, WO 10/065579, WO 11/076510, WO 11/018415, WO 11/018401, WO 11/076699, WO 11/146182, WO 12/055837, WO 12/025557, WO 12/082580). However, specifically at relatively low application rates, the fungicidal efficacy of these compounds is not always adequate.

Since the ecological and economical demands made on modern crop protection agents are increasing constantly, for example with respect to activity spectrum, toxicity, selectivity, application rate, formation of residues and favourable manufacture, and there can furthermore be problems, for example, with resistances, there is a constant need to develop novel crop protection compositions, in particular fungicides, which, at least in some areas, have advantages over the known ones.

It has now been found that, surprisingly, the present heteroaryldihydropyridine derivatives achieve at least some aspects of the objects mentioned and are suitable for use as crop protection compositions, especially as fungicides.

The heteroaryldihydropyridine derivatives usable in accordance with the invention are defined in general terms by the formula (I). The radical definitions of the radical definitions above and specified below of the formula (I) apply to the end products of the formula (I), and also equally to all intermediates (see also below under "Elucidations of the processes and intermediates").

The radical definitions and elucidations listed above and below, in general terms or in areas of preference, can be combined with one another as desired, i.e. including combinations between the particular areas and areas of preference. They apply both to the end products and correspondingly to precursors and intermediates. Moreover, individual definitions may not apply.

Preference is given to those compounds of the formula (I) in which all radicals have the abovementioned preferred definitions.

Particular preference is given to those compounds of the formula (I) in which all radicals have the abovementioned more preferred definitions.

For performance of the processes according to the invention, the starting materials required in each case are generally used in approximately equimolar amounts. However, it is also possible to use one of the components used in each case in a relatively large excess.

Process A

The amides (Ia) can be converted by means of methods described in the literature to the corresponding thioamides (Ib) (e.g. Bioorganic & Medicinal Chemistry Letters, 2009, 19(2), 462-468) (Process A, Scheme 1). This involves reacting the compounds of the formula (Ia) typically with phosphorus pentasulphide or 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane 2,4-disulphide (Lawesson's reagent).

Process A according to the invention is preferably carried out using one or more diluents. The preferred solvents are toluene, tetrahydrofuran, 1,4-dioxane and 1,2-dimethoxyethane.

After the reaction has ended, the compounds (Ib) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography.

Process B

In general, it is possible to prepare compounds of the formula (Ia) from corresponding compounds (IV) which bear a suitable functional group W¹³ to form A in one or more steps, or a suitable leaving group W¹³ for a substitution reaction with a substrate such as A-H (V), where A is defmed as above and H is hydrogen (see Scheme 2, Process B).

For the substitution reaction, at least one equivalent of a base (e.g. sodium hydride, potassium carbonate) or an acid scavenger is used in relation to the starting material of the general formula (IV).

In addition, W¹³ can be transformed in to a desired heterocycle A, by a method analogous to those known in the literature (see Comprehensive Heterocyclic Chemistry vol. 4-6, editors: A. R. Katritzky and C. W. Rees, Pergamon Press, New York, 1984; Comprehensive Heterocyclic Chemistry II, vol. 2-4, editors: A. R. Katritzky, C. W. Rees and E. F. Scriven, Pergamon Press, New York, 1996; The Chemistry of Heterocyclic Compounds, editor: E. C. Taylor, Wiley, New York; Rodd's Chemistry of Carbon Compounds, vol. 2-4, Elsevier, New York).

After the reaction has ended, the compounds (Ia) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography.

Process C

One means of preparing compounds of the formula (IV) from corresponding compounds (VI) with the compounds (VII) is shown in Scheme 3 (process C).

The compound (IV) is prepared analogously to a method known in the literature from a commercially available acid chloride or carboxylic acid (for example, with glycolic acid or hydroxyacetyl chloride, see, for example, WO2005082859; WO 2008013925).

After the reaction has ended, the compounds (IV) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography.

Process D

One means of preparing compounds of the formula (Ia) from corresponding compounds (VI) with the compounds (VIIIa) or (VIIIb) or (VIIIc) is shown in Scheme 4 (process D).

Compounds (VIIIa), (VIIIb) and (VIIIc) are either commercially available or can be prepared by processes described in the literature (see, for example, WO2008091580, WO2007014290 and WO2008091594).

A compound with the general formula (I) can be synthesized analogously to methods described in the literature (see, for example WO2008091594), by a coupling reaction of a compound with the corresponding general formula (VI) with a substrate of the general formula (VIIIa) where W¹ is chlorine, optionally in the presence of an acid scavenger/base.

At least one equivalent of an acid scavenger/a base (for example Hünig's base, triethylamine or commercially available polymeric acid scavengers) is used, in relation to the starting material of the general formula (VI). If the starting material is a salt, at least two equivalents of the acid scavenger are required.

Alternatively, a compound of the formula (I) can also be synthesized from the corresponding compound of the formula (VI) with a substrate of the formula (VIIIa) where W¹ is hydroxyl in the presence of a coupling agent, analogously to methods described in the literature (for example Tetrahedron, 2005, 61, 10827-10852, and references cited therein).

Suitable coupling reagents are, for example, peptide coupling reagents (for example N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide mixed with 4-dimethylaminopyridine, N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide mixed with 1-hydroxybenzotriazole, bromotripyrrolidinophosphonium hexafluorophosphate, O-(7-azabenzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate, etc.).

Furthermore, a compound of the formula (I) can also be prepared step-wise from the corresponding compound of the formula (VI) with phosgene, followed by a substrate of the formula (VIIIc) in the presence of an acid scavenger/a base if necessary. Similarly, a compound of the formula (I) can be synthesized by a compound of the formula (VI) with a substrate of the formula (VIIIc) in the presence of an acid scavenger/a base if necessary.

After the reaction has ended, the compounds (I) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography.

Process F

One means of preparing compounds of the formula (VI) from corresponding compounds (IX) is shown in Scheme 6 (process F).

A compound of the formula (IX) is converted to a compound of the formula (VI) by suitable methods for removing protecting groups described in the literature ("Protective Groups in Organic Synthesis"; Theodora W. Greene, Peter G. M. Wuts; Wiley-Interscience; Third Edition; 1999; 494-653).

For example, tert-Butoxycarbonyl and benzyloxycarbonyl protecting groups can be removed in an acidic medium (for example with hydrochloric acid or trifluoroacetic acid). Acetyl protecting groups can be removed under basic conditions (for example with potassium carbonate or caesium carbonate). Benzylic protecting groups can be removed hydrogenolytically with hydrogen in the presence of a catalyst (for example palladium on activated carbon).

After the reaction has ended, the compounds (VI) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography, or can, if desired, also be used in the next step without prior purification. It is also possible to isolate the compound of the general formula (VI) as a salt, for example as a salt of hydrochloric acid or of trifluoroacetic acid.

Process G

In general, it is possible to prepare compounds of the formula (IX) from corresponding compounds (X) which bear a suitable functional group W³ to form in one or more steps a substituted or non-substituted dihydropyridine ring (see Scheme 7, Process G). There are literature methods already known for the preparation of dihydropyridine ring (see Chemische Berichte, 1881, 14, 1637-1638; European Journal of Medicinal Chemistry, 2011, 46, 1564-1571; Tetrahedron Letters, 1982, 23, 429-432; European Journal of Organic Chemistry, 2003, 23, 4586-4592), and one can apply such a method to prepare compounds of the formula (IX).

A derivative (Xb) of the formula (X), where W³ is a halogen can be prepared from (Xa), where W³ is amino, either by Sandmeyer reaction (Synthesis, 2012, 44, 1026-1029). Another derivative (Xc) of the formula (X), where W³ is formyl, can be prepared by a known formylation method from (Xb), for example, typically by trans-metallation, followed by addition of DMF and acidic work-up (see WO 2006092268).

For instance, the compounds (IX) can be prepared by Hantzsch Dihydropyridine Synthesis from (Xc), two equivalents of a β-ketoester in the presence of ammonia or a primary amine, analogous to the literature methods (Chemische Berichte, 1881, 14, 1637-1638; European Journal of Medicinal Chemistry, 2011, 46, 1564-1571).

For instance, the compounds (IX) can also be prepared by addition of an organocuprate reagent drived from (Xb) to a substituted or non-substituted pyridine in the presence of an appropriate electrophile, for example, an alkyl chloroformate. The 4-position of the pyridine must be unsubstituted. The reaction can be performed under a similar reaction conditions to the literature methods (see for example, Canadian Journal of Chemistry, 1974, 3563-3564).

After the reaction has ended, the compounds (IX) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography, or can, if desired, also be used in the next step without prior purification.

Process H

One means of preparing compounds of the formula (Xa) from corresponding compounds (XI) is shown in Scheme 8 (process H).

A compound of the formula (XI) is converted in the presence of thiourea to a compound of the formula (Xa) by Hantzch thiazole synthesis described in the literature (Organic & Biomolecular Chemistry, 2012, 10, 1093-1101; Journal of Medicinal Chemistry, 1991, 34, 600-605).

The compound with the general formula (XI) can be synthesized analogously to methods well described in the literature (see, for example WO 2008013925).

After the reaction has ended, the compounds (Xa) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography, or can, if desired, also be used in the next step without prior purification.

Process I

In general, it is also possible to prepare compounds of the formula (I) from corresponding compounds (II) and (XII) with suitable functional groups G^f and W⁷ (Scheme 9, Process I). There are numerous literature methods for the preparation of heterocycles (see WO 2008/013622; Comprehensive Heterocyclic Chemistry vol. 4-6, editors: A. R. Katritzky and C. W. Rees, Pergamon Press, New York, 1984; Comprehensive Heterocyclic Chemistry II, vol. 2-4, editors: A. R. Katritzky, C. W. Rees and E. F. Scriven, Pergamon Press, New York, 1996; The Chemistry of Heterocyclic Compounds, editor: E. C. Taylor, Wiley, New York; Rodd's Chemistry of Carbon Compounds, vol. 2-4, Elsevier, New York; Synthesis, 1982, 6, 508-509; Tetrahedron, 2000, 56, 1057-1064).

After the reaction has ended, the compounds (Ia) are separated from the reaction mixture by one of the customary separation techniques. If necessary, the compounds are purified by recrystallization or chromatography.

Process J

In general, it is possible to prepare intermediates of the formula (IIa) from corresponding compounds (III) which bear a suitable functional group W¹³ to form A in one or more steps, or a suitable leaving group W¹³ for a substitution reaction with a substrate such as A-H (V), where A is defined as above and H is hydrogen (see Scheme 10, Process J). Process J (Scheme 10) is performed analogously to process B (Scheme 2).

Process K

In general, it is possible to prepare intermediates of the formula (III) from corresponding compounds (III) with compounds (VII) (see Scheme 11, Process K). Process K (Scheme 11) is performed analogously to process C (Scheme 3).

Process L

In general, it is possible to prepare intermediates of the formula (II) from corresponding compounds (XIII) with a compound of the general formula (VIIIa), (VIIIb) or (VIIIc) (see Scheme 12, Process L). Process L (Scheme 12) is performed analogously to process D (Scheme 4).

Process M

In general, it is possible to prepare intermediates of the formula (XIII) from corresponding compounds (XIV) by removing the protecting group W² (see Scheme 13, Process M). Process M (Scheme 13) is performed analogously to process F (Scheme 6).

Process M

In general, it is possible to prepare intermediates of the formula (XIV) from corresponding compounds (XV) with compounds (XI) (see Scheme 14, Process N). Process N (Scheme 14) is performed analogously to process G (Scheme 7).

Process O

In general, it is possible to prepare intermediates of the formula (XV) from corresponding compounds (XVI) with thiourea (see Scheme 15, Process O). Compounds of the general formula (XVI) are either commercially available (for example, from ethyl bromopyruvate) or readily available from commercially avaialable starting materials by known methods in the literature (for example, bromination of ethyl pyruvate: Journal of the American Chemical Society, 1944, 66, 1656-9). If necessary, a substituent group G^f is protected by an appropriate protecting group. Furthermore, a substituent group G^f can be derived after a Hantzsch cyclisation process from another functional group that is more suitable for the cyclisation process. Process O (Scheme 15) is performed analogously to process H (Scheme 8).

It is recognized that some reagents and reaction conditions described above for preparation of compounds of the formula (I) may not be compatible with particular functionalities present in the intermediate compounds. In these cases, the introduction of protection/deprotection sequences or of mutual conversions of functional groups into the synthesis helps to obtain the desired products. The use and selection of the protecting groups is obvious to the person skilled in the art of chemical synthesis (see, for example, "Protective Groups in Organic Synthesis"; Third Edition; 494-653, and literature cited therein). The person skilled in the art will recognize that, in some cases, after the introduction of a given reagent as shown in an individual scheme, it may be necessary to perform additional routine synthesis steps not described individually in order to complete the synthesis of compounds of the formula (I). The person skilled in the art will likewise recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in a sequence other than the implied sequence shown specifically, in order to prepare the compounds of the formula (I).

The workup is carried out by customary methods. If necessary, the compounds are purified by recrystallization or chromatography.

The invention also relates to a method for controlling unwanted microorganisms, characterized in that the inventive heteroaryldihydropyridine derivatives are applied to the microorganisms and/or in their habitat.

The invention further relates to seed which has been treated with at least one inventive heteroaryldihydropyridine derivative.

The invention finally provides a method for protecting seed against unwanted microorganisms by using seed treated with at least one heteroaryldihydropyridine derivative according to the present invention.

The inventive substances have potent microbicidal activity and can be used for control of unwanted microorganisms, such as fungi and bacteria, in crop protection and in the protection of materials.

The inventive heteroaryldihydropyridine derivatives of the formula (I) have very good fungicidal properties and can be used in crop protection, for example for control of Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes.

Bactericides can be used in crop protection, for example, for control of Pseudomonadaceae, Rhizobiaceae, Enterobacteriaceae, Corynebacteriaceae and Streptomycetaceae.

The inventive fungicidal compositions can be used for curative or protective control of phytopathogenic fungi. The invention therefore also relates to curative and protective methods for controlling phytopathogenic fungi by the use of the inventive active ingredients or compositions, which are applied to the seed, the plant or plant parts, the fruit or the soil in which the plants grow.

The inventive compositions for controlling phytopathogenic fungi in crop protection comprise an effective but non-phytotoxic amount of the inventive active ingredients. An "effective but non-phytotoxic amount" means an amount of the inventive composition which is sufficient to control the fungal disease of the plant in a satisfactory manner or to eradicate the fungal disease completely, and which, at the same time, does not cause any significant symptoms of phytotoxicity. In general, this application rate may vary within a relatively wide range. It depends on several factors, for example on the fungus to be controlled, the plant, the climatic conditions and the ingredients of the inventive compositions.

All plants and plant parts can be treated in accordance with the invention. Plants are understood here to mean all plants and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants may be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant cultivars which are protectable and non-protectable by plant breeders' rights. Plant parts are understood to mean all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples of which include leaves, needles, stalks, stems, flowers, fruit bodies, fruits and seeds, and also roots, tubers and rhizomes. The plant parts also include harvested material and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, slips and seeds.

Plants which can be treated in accordance with the invention include the following: cotton, flax, grapevine, fruit, vegetables, such as Rosaceae sp. (for example pome fruits such as apples and pears, but also stone fruits such as apricots, cherries, almonds and peaches, and soft fruits such as strawberries), Ribesioidae sp., Juglandaceae sp., Betulaceae sp., Anacardiaceae sp., Fagaceae sp., Moraceae sp., Oleaceae sp., Actinidaceae sp., Lauraceae sp., Musaceae sp.

(for example maize, turf, cereals such as wheat, rye, rice, barley, oats, millet and triticale), Asteraceae sp. (for example sunflower), Brassicaceae sp. (for example white cabbage, red cabbage, broccoli, cauliflower, Brussels sprouts, pak choi, kohkabi, radishes, and oilseed rape, mustard, horseradish and cress), Fabacae sp. (for example bean, peanuts), Papilionaceae sp. (for example soya bean), Solanaceae sp. (for example potatoes), Chenopodiaceae sp. (for example sugar beet, fodder beet, swiss chard, beetroot); useful plants and ornamental plants for gardens and wooded areas; and genetically modified varieties of each of these plants.

Fungal diseases on roots and the stem base caused, for example, by black root rot (Calonectria crotalariae), charcoal rot (Macrophomina phaseolina), fusarium blight or wilt, root rot, and pod and collar rot (Fusarium oxysporum, Fusarium orthoceras, Fusarium semitectum, Fusarium equiseti), mycoleptodiscus root rot (Mycoleptodiscus terrestris), neocosmospora (Neocosmospora vasinfecta), pod and stem blight (Diaporthe phaseolorum), stem canker (Diaporthe phaseolorum var. caulivora), phytophthora rot (Phytophthora megasperma), brown stem rot (Phialophora gregata), pythium rot (Pythium aphanidermatum, Pythium irregulare, Pythium debaryanum, Pythium myriotylum, Pythium ultimum), rhizoctonia root rot, stem decay, and damping-off (Rhizoctonia solani), sclerotinia stem decay (Sclerotinia sclerotiorum), sclerotinia southern blight (Sclerotinia rolfsii), thielaviopsis root rot (Thielaviopsis basicola).

The inventive active ingredients also have very good fortifying action in plants. They are therefore suitable for mobilizing the plant's own defences against attack by undesirable microorganisms.

Plant-fortifying (resistance-inducing) substances are understood to mean, in the present context, those substances which are capable of stimulating the defence system of plants in such a way that the treated plants, when subsequently inoculated with undesirable microorganisms, develop a high degree of resistance to these microorganisms.

In the present case, undesirable microorganisms are understood to mean phytopathogenic fungi and bacteria. The inventive substances can thus be used to protect plants for a certain period after the treatment against attack by the pathogens mentioned. The period for which protection is provided generally extends over 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active ingredients.

The fact that the active ingredients are well tolerated by plants at the concentrations required for controlling plant diseases allows the treatment of above-ground parts of plants, of propagation stock and seeds, and of the soil.

The inventive active ingredients can be used particularly successfully to control diseases in viticulture and potato, fruit and vegetable growing, for example against powdery mildew fungi, Oomycetes, for example Phytophthora, Plasmopara, Pseudoperonospora and Pythium species.

The inventive active ingredients are also suitable for enhancing harvest yield. In addition, they have low toxicity and are well tolerated by plants.

If appropriate, the inventive compounds can, at certain concentrations or application rates, also be used as herbicides, safeners, growth regulators or agents to improve plant properties, or as microbicides, for example as fungicides, antimycotics, bactericides, viricides (including agents against viroids) or as agents against MLO (mycoplasnia-like organisms) and RLO (rickettsia-like organisms). If appropriate, they can also be used as insecticides. If appropriate, they can also be used as intermediates or precursors for the synthesis of other active ingredients.

The inventive active ingredients, when they are well tolerated by plants, have favourable homeotherm toxicity and are well tolerated by the environment, are suitable for protecting plants and plant organs, for enhancing harvest yields, for improving the quality of the harvested material in agriculture, in horticulture, in animal husbandry, in forests, in gardens and leisure facilities, in the protection of stored products and of materials, and in the hygiene sector. They can preferably be used as crop protection agents. They are effective against normally sensitive and resistant species and against all or some stages of development.

The inventive treatment of the plants and plant parts with the active ingredients or compositions is effected directly or by action on their surroundings, habitat or storage space by the customary treatment methods, for example by dipping, spraying, atomizing, irrigating, evaporating, dusting, fogging, broadcasting, foaming, painting, spreading-on, watering (drenching), drip irrigating and, in the case of propagation material, especially in the case of seeds, also by dry seed treatment, wet seed treatment, slurry treatment, incrustation, coating with one or more coats, etc. It is also possible to deploy the active ingredients by the ultra-low volume method or to inject the active ingredient preparation/the active ingredient itself into the soil.

In addition, in the protection of materials, the inventive active ingredients or compositions can be used for protection of industrial materials against attack and destruction by unwanted microorganisms, for example fungi.

Industrial materials in the present context are understood to mean inanimate materials which have been prepared for use in industry. For example, industrial materials which are to be protected by inventive active ingredients from microbial alteration or destruction may be adhesives, sizes, paper and board, textiles, leather, wood, paints and plastic articles, cooling lubricants and other materials which can be infected with or destroyed by microorganisms. The range of materials to be protected also includes parts of production plants, for example cooling water circuits, which may be impaired by the proliferation of microorganisms. Industrial materials within the scope of the present invention preferably include adhesives, sizes, paper and cardboard, leather, wood, paints, cooling lubricants and heat transfer fluids, more preferably wood. The inventive active ingredients or compositions may prevent adverse effects, such as rotting, decay, discoloration, decoloration or formation of mould.

The inventive method for control of unwanted fungi can also be used for protection of storage goods. Storage goods are understood to mean natural substances of vegetable or animal origin or processed products thereof which are of natural origin, and for which long-term protection is desired. Storage goods of vegetable origin, for example plants or plant parts, such as stems, leaves, tubers, seeds, fruits, grains, can be protected freshly harvested or after processing by (pre)drying, moistening, comminuting, grinding, pressing or roasting. Storage goods also include timber, both unprocessed, such as construction timber, electricity poles and barriers, or in the form of finished products, such as furniture. Storage goods of animal origin are, for example, hides, leather, furs and hairs. The inventive active ingredients may prevent adverse effects, such as rotting, decay, discoloration, decoloration or formation of mould.

Microorganisms capable of degrading or altering the industrial materials include, for example, bacteria, fungi, yeasts, algae and slime organisms. The inventive active ingredients preferably act against fungi, especially moulds, wood-discoloring and wood-destroying fungi (Basidiomycetes), and against slime organisms and algae. Examples include microorganisms of the following genera: Alternaria, such as Alternaria tenuis; Aspergillus, such as Aspergillus niger; Chaetomium, such as Chaetomium globosum; Coniophora, such as Coniophora puetana; Lentinus, such as Lentinus tigrinus; Penicillium, such as Penicillium glaucum; Polyporus, such as Polyporus versicolor; Aureobasidium, such as Aureobasidium pullulans; Sclerophoma, such as Sclerophoma pityophila; Trichoderma, such as Trichoderma viride; Escherichia, such as Escherichia coli; Pseudomonas, such as Pseudomonas aeruginosa; Staphylococcus, such as Staphylococcus aureus.

The present invention further relates to a composition for controlling unwanted microorganisms, comprising at least one of the inventive heteroaryldihydropyridine derivatives. These are preferably fungicidal compositions which comprise agriculturally suitable auxiliaries, solvents, carriers, surfactants or extenders.

According to the invention, a carrier is a natural or synthetic, organic or inorganic substance with which the active ingredients are mixed or combined for better applicability, in particular for application to plants or plant parts or seed. The carrier, which may be solid or liquid, is generally inert and should be suitable for use in agriculture.

Useful solid carriers include: for example ammonium salts and natural rock flours, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and synthetic rock flours, such as finely divided silica, alumina and silicates; useful solid carriers for granules include: for example, crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic flours, and granules of organic material such as paper, sawdust, coconut shells, maize cobs and tobacco stalks; useful emulsifiers and/or foam-formers include: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and also protein hydrolysates; suitable dispersants are nonionic and/or ionic substances, for example from the classes of the alcohol-POE and/or -POP ethers, acid and/or POP POE esters, alkylaryl and/or POP POE ethers, fat and/or POP POE adducts, POE- and/or POP-polyol derivatives, POE- and/or POP-sorbitan or -sugar adducts, alkyl or aryl sulphates, alkyl- or arylsulphonates and alkyl or aryl phosphates or the corresponding PO-ether adducts. Additionally suitable are oligo- or polymers, for example those derived from vinylic monomers, from acrylic acid, from EO and/or PO alone or in combination with, for example, (poly)alcohols or (poly)amines. It is also possible to use lignin and its sulphonic acid derivatives, unmodified and modified celluloses, aromatic and/or aliphatic sulphonic acids and also their adducts with formaldehyde.

The active ingredients can be converted to the customary formulations, such as solutions, emulsions, wettable powders, water- and oil-based suspensions, powders, dusts, pastes, soluble powders, soluble granules, granules for broadcasting, suspoemulsion concentrates, natural products impregnated with active ingredient, synthetic substances impregnated with active ingredient, fertilizers and also microencapsulations in polymeric substances.

The active ingredients can be applied as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, emulsions, water- or oil-based suspensions, powders, wettable powders, pastes, soluble powders, dusts, soluble granules, granules for broadcasting, suspoemulsion concentrates, natural products impregnated with active ingredient, synthetic substances impregnated with active ingredient, fertilizers and also microencapsulations in polymeric substances. Application is accomplished in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading-on and the like. It is also possible to deploy the active ingredients by the ultra-low volume method or to inject the active ingredient preparation/the active ingredient itself into the soil. It is also possible to treat the seed of the plants.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active ingredients with at least one customary extender, solvent or diluent, emulsifier, dispersant and/or binder or fixing agent, wetting agent, a water repellent, if appropriate siccatives and UV stabilizers and if appropriate dyes and pigments, antifoams, preservatives, secondary thickeners, stickers, gibberellins and also other processing auxiliaries.

The present invention includes not only formulations which are already ready for use and can be deployed with a suitable apparatus to the plant or the seed, but also commercial concentrates which have to be diluted with water prior to use.

The inventive active ingredients may be present as such or in their (commercial) formulations and in the use forms prepared from these formulations as a mixture with other (known) active ingredients, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth regulators, herbicides, fertilizers, safeners and/or semiochemicals.

The auxiliaries used may be those substances which are suitable for imparting particular properties to the composition itself or and/or to preparations derived therefrom (for example spray liquors, seed dressings), such as certain technical properties and/or also particular biological properties. Typical auxiliaries include: extenders, solvents and carriers.

Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, for example from the classes of the aromatic and nonaromatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which may optionally also be substituted, etherified and/or esterified), the ketones (such as acetone, cyclohexanone), esters (including fats and oils) and (poly)ethers, the unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, the sulphones and sulphoxides (such as dimethyl sulphoxide).

Liquefied gaseous extenders or carriers are understood to mean liquids which are gaseous at standard temperature and under standard pressure, for example aerosol propellants such as halohydrocarbons, or else butane, propane, nitrogen and carbon dioxide.

In the formulations it is possible to use tackifiers such as carboxymethylcellulose, natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids. Further additives may be mineral and vegetable oils.

If the extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Useful liquid solvents are essentially: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, or else water.

The inventive compositions may additionally comprise further components, for example surfactants. Suitable surfactants are emulsifiers and/or foam formers, dispersants or wetting agents having ionic or nonionic properties, or mixtures of these surfactants. Examples thereof are salts of polyacrylic acid, salts of lignosulphonic acid, salts of phenolsulphonic acid or naphthalenesulphonic acid, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines, substituted phenols (preferably alkylphenols or arylphenols), salts of sulphosuccinic esters, taurine derivatives (preferably alkyl taurates), phosphoric esters of polyethoxylated alcohols or phenols, fatty esters of polyols, and derivatives of the compounds containing sulphates, sulphonates and phosphates, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, protein hydrolysates, lignosulphite waste liquors and methylcellulose. The presence of a surfactant is necessary if one of the active ingredients and/or one of the inert carriers is insoluble in water and when application is effected in water. The proportion of surfactants is between 5 and 40 per cent by weight of the inventive composition.

It is possible to use dyes such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyes such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Further additives may be perfumes, mineral or vegetable, optionally modified oils, waxes and nutrients (including trace nutrients), such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Additional components may be stabilizers, such as cold stabilizers, preservatives, antioxidants, light stabilizers, or other agents which improve chemical and/or physical stability.

If appropriate, other additional components may also be present, for example protective colloids, binders, adhesives, thickeners, thixotropic substances, penetrants, stabilizers, sequestering agents, complex formers. In general, the active ingredients can be combined with any solid or liquid additive commonly used for formulation purposes.

The formulations contain generally between 0.05 and 99% by weight, 0.01 and 98% by weight, preferably between 0.1 and 95% by weight, more preferably between 0.5 and 90% of active ingredient, most preferably between 10 and 70 per cent by weight.

The formulations described above can be used in an inventive method for controlling unwanted microorganisms, in which the inventive heteroaryldihydropyridine derivatives are applied to the microorganisms and/or in their habitat.

The inventive active ingredients can also be used, as such or in formulations thereof, in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, in order thus to broaden, for example, the activity spectrum or to prevent development of resistance.

Useful mixing partners include, for example, known fungicides, insecticides, acaricides, nematicides or else bactericides (see also Pesticide Manual, 14th ed.).

A mixture with other known active ingredients, such as herbicides, or with fertilizers and growth regulators, safeners and/or semiochemicals, is also possible.

Application is accomplished in a customary manner appropriate for the use forms.

The invention furthermore includes a method for treating seed.

A further aspect of the present invention relates in particular to seed treated with at least one of the inventive heteroaryldihydropyridine derivatives. The inventive seeds are used in methods for protection of seed from phytopathogenic harmful fungi. In these methods, seed treated with at least one inventive active ingredient is used.

The inventive active ingredients or compositions are also suitable for the treatment of seed. A large part of the damage to crop plants caused by harmful organisms is triggered by the infection of the seed during storage or after sowing both during and after germination of the plant. This phase is particularly critical since the roots and shoots of the growing plant are particularly sensitive, and even small damage may result in the death of the plant. Accordingly, there is great interest in protecting the seed and the germinating plant by using appropriate compositions.

The control of phytopathogenic harmful fungi by treating the seed of plants has been known for a long time and is the subject of constant improvements. However, the treatment of seed entails a series of problems which cannot always be solved in a satisfactory manner. For instance, it is desirable to develop methods for protecting the seed and the germinating plant, which dispense with, or at least significantly reduce, the additional deployment of crop protection compositions after planting or after emergence of the plants. It is also desirable to optimize the amount of the active ingredient used so as to provide the best possible protection for the seed and the germinating plant from attack by phytopathogenic fungi, but without damaging the plant itself by the active ingredient used. In particular, methods for the treatment of seed should also take into consideration the intrinsic fungicidal properties of transgenic plants in order to achieve optimum protection of the seed and the germinating plant with a minimum of crop protection compositions being employed.

The present invention therefore also relates to a method for protecting seed and germinating plants against attack by animal pests and/or phytopathogenic harmful fungi by treating the seed with an inventive composition. The invention also relates to the use of the compositions according to the invention for treating seed for protecting the seed and the germinating plant against phytopathogenic fungi. The invention further relates to seed which has been treated with an inventive composition for protection from phytopathogenic fungi.

Animal pests and/or phytopathogenic harmful fungi which damage plants post-emergence are controlled primarily by the treatment of the soil and of the exposed plant parts with crop protection compositions. Owing to the concerns regarding a possible influence of the crop protection compositions on the environment and the health of humans and animals, there are efforts to reduce the amount of active ingredients deployed.

One of the advantages of the present invention is that, because of the particular systemic properties of the inventive compositions, the treatment of the seed with these compositions not only protects the seed itself, but also the resulting plants after emergence, from animal pests and/or phytopathogenic harmful fungi. In this way, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.

It is likewise considered to be advantageous that the inventive active ingredients or compositions can be used especially also for transgenic seed, in which case the plant which grows from this seed is capable of expressing a protein which acts against pests. The treatment of such seed with the inventive active ingredients or compositions, merely through the expression of the protein, for example an insecticidal protein, can result in control of certain pests. Surprisingly, a further synergistic effect can be observed in this case, which additionally increases the effectiveness for protection against attack by pests.

The inventive compositions are suitable for protection of seed of any plant variety which is used in agriculture, in the greenhouse, in forests or in horticulture. More particularly, the seed is that of cereals (such as wheat, barley, rye, millet and oats), maize, cotton, soya, rice, potatoes, sunflower, bean, coffee, beet (e.g. sugar beet and fodder beet), peanut, vegetables (such as tomato, cucumber, onions and lettuce), lawns and ornamental plants. Of particular significance is the treatment of the seed of cereals (such as wheat, barley, rye and oats), maize and rice.

As also described below, the treatment of transgenic seed with the inventive active ingredients or compositions is of particular significance. This refers to the seed of plants containing at least one heterologous gene which allows the expression of a polypeptide or protein having insecticidal properties. The heterologous gene in transgenic seed may originate, for example, from microorganisms of the species Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter, Glomus or Gliocladium. This heterologous gene preferably originates from Bacillus sp., in which case the gene product is effective against the European corn borer and/or the Western corn rootworm. Particularly preferably, the heterologous gene originates from Bacillus thuringiensis.

In the context of the present invention, the inventive composition is applied to the seed either alone or in a suitable formulation. Preferably, the seed is treated in a state in which it is sufficiently stable for no damage to occur in the course of treatment. In general, the seed can be treated at any time between harvest and sowing. It is customary to use seed which has been separated from the plant and freed from cobs, shells, stalks, coats, hairs or the flesh of the fruits. For example, it is possible to use seed which has been harvested, cleaned and dried down to a moisture content of less than 15% by weight. Alternatively, it is also possible to use seed which, after drying, for example, has been treated with water and then dried again.

When treating the seed, it generally has to be ensured that the amount of the inventive composition applied to the seed and/or the amount of further additives is selected such that the germination of the seed is not impaired, or that the resulting plant is not damaged. This must be ensured particularly in the case of active ingredients which can exhibit phytotoxic effects at certain application rates.

The inventive compositions can be applied directly, i.e. without containing any other components and without having been diluted. In general, it is preferable to apply the compositions to the seed in the form of a suitable formulation. Suitable formulations and methods for seed treatment are known to those skilled in the art and are described, for example, in the following documents: US 4,272,417, US 4,245,432, US 4,808,430, US 5,876,739, US 2003/0176428, WO 2002/080675, WO 2002/028186.

The active ingredients usable in accordance with the invention can be converted to the customary seed dressing formulations, such as solutions, emulsions, suspensions, powders, foams, slurries or other coating compositions for seed, and also ULV formulations.

These formulations are prepared in a known manner, by mixing the active ingredients or active ingredient combinations with customary additives, for example customary extenders and solvents or diluents, dyes, wetting agents, dispersants, emulsifiers, antifoams, preservatives, secondary thickeners, adhesives, gibberellins, and also water.

Useful dyes which may be present in the seed dressing formulations usable in accordance with the invention are all dyes which are customary for such purposes. It is possible to use either pigments, which are sparingly soluble in water, or dyes, which are soluble in water. Examples include the dyes known by the names Rhodamine B, C.I. Pigment Red 112 and C.I. Solvent Red 1.

Useful wetting agents which may be present in the seed dressing formulations usable in accordance with the invention are all substances which promote wetting and which are conventionally used for the formulation of active agrochemical ingredients. Usable with preference are alkylnaphthalenesulphonates, such as diisopropyl- or diisobutylnaphthalenesulphonates.

Useful dispersants and/or emulsifiers which may be present in the seed dressing formulations usable in accordance with the invention are all nonionic, anionic and cationic dispersants conventionally used for the formulation of active agrochemical ingredients. Usable with preference are nonionic or anionic dispersants or mixtures of nonionic or anionic dispersants. Useful nonionic dispersants include especially ethylene oxide/propylene oxide block polymers, alkylphenol polyglycol ethers and tristryrylphenol polyglycol ether, and the phosphated or sulphated derivatives thereof. Suitable anionic dispersants are especially lignosulphonates, polyacrylic acid salts and arylsulphonate/formaldehyde condensates.

Antifoams which may be present in the seed dressing formulations usable in accordance with the invention are all foam-inhibiting substances conventionally used for the formulation of active agrochemical ingredients. Silicone antifoams and magnesium stearate can be used with preference.

Preservatives which may be present in the seed dressing formulations usable in accordance with the invention are all substances usable for such purposes in agrochemical compositions. Examples include dichlorophene and benzyl alcohol hemiformal.

Secondary thickeners which may be present in the seed dressing formulations usable in accordance with the invention are all substances usable for such purposes in agrochemical compositions. Preferred examples include cellulose derivatives, acrylic acid derivatives, xanthan, modified clays and finely divided silica.

Adhesives which may be present in the seed dressing formulations usable in accordance with the invention are all customary binders usable in seed dressing products. Preferred examples include polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and tylose.

The gibberellins which may be present in the seed dressing formulations usable in accordance with the invention may preferably be gibberellins A1, A3 (= gibberellic acid), A4 and A7; particular preference is given to using gibberellic acid. The gibberellins are known (cf. R. Wegler "Chemie der Pflanzenschutz - und Schädlingsbekämpfungsmittel" [Chemistry of Crop Protection Agents and Pesticides], vol. 2, Springer Verlag, 1970, p. 401-412).

The seed dressing formulations usable in accordance with the invention can be used to treat a wide variety of different kinds of seed either directly or after prior dilution with water. For instance, the concentrates or the preparations obtainable therefrom by dilution with water can be used to dress the seed of cereals, such as wheat, barley, rye, oats, and triticale, and also the seed of maize, rice, oilseed rape, peas, beans, cotton, sunflowers, and beets, or else a wide variety of different vegetable seed. The seed dressing formulations usable in accordance with the invention, or the dilute preparations thereof, can also be used to dress seed of transgenic plants. In this case, additional synergistic effects may also occur in interaction with the substances formed by expression.

For treatment of seed with the seed dressing formulations usable in accordance with the invention, or the preparations prepared therefrom by adding water, all mixing units usable customarily for the seed dressing are useful. Specifically, the procedure in the seed dressing is to place the seed into a mixer, to add the particular desired amount of seed dressing formulations, either as such or after prior dilution with water, and to mix everything until the formulation is distributed homogeneously on the seed. If appropriate, this is followed by a drying operation.

The application rate of the seed dressing formulations usable in accordance with the invention can be varied within a relatively wide range. It is guided by the particular content of the active ingredients in the formulations and by the seed. The application rates of active ingredient combination are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 15 g per kilogram of seed.

In addition, the inventive compounds of the formula (I) also have very good antimycotic effects. They have a very broad antimycotic activity spectrum, especially against dermatophytes and yeasts, moulds and diphasic fungi (for example against Candida species, such as Candida albicans, Candida glabrata), and Epidermophyton floccosum, Aspergillus species, such as Aspergillus niger and Aspergillus fumigatus, Trichophyton species, such as Trichophyton mentagrophytes, Microsporon species such as Microsporon canis and audouinii. The enumeration of these fungi by no means constitutes a restriction of the mycotic spectrum covered, and is merely of illustrative character.

The inventive active ingredients of the formula (I) can therefore be used both in medical and in non-medical applications.

The active ingredients can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is accomplished in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading-on and the like. It is also possible to deploy the active ingredients by the ultra-low volume method or to inject the active ingredient preparation/the active ingredient itself into the soil. It is also possible to treat the seed of the plants.

When using the inventive active ingredients as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. The application rate of the inventive active ingredients is

• in the case of treatment of plant parts, for example leaves: from 0.1 to 10 000 g/ha, preferably from 10 to 1000 g/ha, more preferably from 50 to 300 g/ha (in the case of application by watering or dripping, it is even possible to reduce the application rate, especially when inert substrates such as rockwool or perlite are used);
• in the case of seed treatment: from 2 to 200 g per 100 kg of seed, preferably from 3 to 150 g per 100 kg of seed, more preferably from 2.5 to 25 g per 100 kg of seed, even more preferably from 2.5 to 12.5 g per 100 kg of seed;
• in the case of soil treatment: from 0.1 to 10 000 g/ha, preferably from 1 to 5000 g/ha.

These application rates are merely by way of example and are not limiting for the purposes of the invention.

The inventive active ingredients are used in the veterinary sector and in animal husbandry in a known manner, by enteral administration in the form of, for example, tablets, capsules, potions, drenches, granules, pastes, boluses, the feed-through process and suppositories, by parenteral administration, for example by injection (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal use in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing and powdering, and also with the aid of molded articles containing the active ingredient, such as collars, ear marks, tail marks, limb bands, halters, marking devices and the like.

When used for livestock, poultry, domestic animals and the like, the active ingredients of the formula (I) can be used as formulations (for example powders, emulsions, flowables) comprising the active ingredients in an amount of 1 to 80% by weight, either directly or after 100 to 10 000-fold dilution, or they may be used as a chemical bath.

The ready-to-use compositions may optionally also comprise other insecticides, and optionally also one or more fungicides.

With respect to possible additional mixing partners, reference is made to the insecticides and fungicides mentioned above.

At the same time, the inventive compounds can be used for protection of objects which come into contact with saltwater or brackish water, especially hulls, screens, nets, buildings, moorings and signalling systems, against fouling.

In addition, the inventive compounds can be used as anti-fouling compositions, alone or in combinations with other active ingredients.

The inventive treatment method can be used for the treatment of genetically modified organisms (GMOs), for example plants or seeds. Genetically modified plants (or transgenic plants) are plants in which a heterologous gene has been integrated stably into the genome. The expression "heterologous gene" essentially means a gene which is provided or assembled outside the plant and, when introduced into the nuclear, chloroplastic or hypochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example antisense technology, cosuppression technology or RNAi technology [RNA interference]). A heterologous gene present in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive ("synergistic") effects. For example, the following effects exceeding the effects actually to be expected are possible: reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the active ingredients and compositions which can be used in accordance with the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher yields, bigger fruits, larger plant height, greener leaf colour, earlier flowering, higher quality and/or a higher nutritional value of the harvested products, higher sugar concentration within the fruits, better storage stability and/or processability of the harvested products.

At certain application rates, the inventive active ingredient combinations may also have a fortifying effect on plants. Accordingly, they are suitable for mobilizing the defence system of the plant against attack by unwanted phytopathogenic fungi and/or microorganisms and/or viruses. This may, if appropriate, be one of the reasons for the enhanced activity of the combinations according to the invention, for example against fungi. Plant-fortifying (resistance-inducing) substances shall be understood to mean, in the present context, also those substances or combinations of substances which are capable of stimulating the defence system of plants in such a way that, when subsequently inoculated with unwanted phytopathogenic fungi and/or microorganisms and/or viruses, the plants treated display a substantial degree of resistance to these unwanted phytopathogenic fungi and/or microorganisms and/or viruses. In the present case, unwanted phytopathogenic fungi and/or microorganisms and/or viruses are understood to mean phytopathogenic fungi, bacteria and viruses. Thus, the substances according to the invention can be employed for protecting plants against attack by the abovementioned pathogens within a certain period of time after the treatment. The period within which protection is achieved generally extends for from 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active ingredients.

Plants and plant varieties which are preferably treated according to the invention include all plants which have genetic material which imparts particularly advantageous, useful traits to these plants (whether obtained by breeding and/or biotechnological means).

Plants and plant varieties which are also preferably treated according to the invention are resistant against one or more biotic stress factors, i.e. said plants have a better defence against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.

Plants and plant varieties which may also be treated according to the invention are those plants which are resistant to one or more abiotic stress factors. Abiotic stress conditions may include, for example, drought, cold and hot conditions, osmotic stress, waterlogging, increased soil salinity, increased exposure to minerals, ozone conditions, strong light conditions, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients or shade avoidance.

Plants and plant varieties which can likewise be treated in accordance with the invention are those plants which are characterized by increased yield properties. Increased yield in said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can also be affected by improved plant architecture (under stress and non-stress conditions), including early flowering, flowering control for hybrid seed production, seedling vigour, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processibility and better storage stability.

Plants that may be treated according to the invention are hybrid plants that already express the characteristics of heterosis, or hybrid effect, which results in generally higher yield, vigour, health and resistance towards biotic and abiotic stress factors. Such plants are typically produced by crossing an inbred male-sterile parent line (the female parent) with another inbred male-fertile parent line (the male parent). The hybrid seed is typically harvested from the male-sterile plants and sold to growers. Male-sterile plants can sometimes (e.g. in corn) be produced by detasseling (i.e. the mechanical removal of the male reproductive organs or male flowers) but, more typically, male sterility is the result of genetic determinants in the plant genome. In that case, and especially when seed is the desired product to be harvested from the hybrid plants, it is typically beneficial to ensure that male fertility in hybrid plants, which contain the genetic determinants responsible for male sterility, is fully restored. This can be accomplished by ensuring that the male parents have appropriate fertility restorer genes which are capable of restoring the male fertility in hybrid plants that contain the genetic determinants responsible for male sterility. Genetic determinants for male sterility may be located in the cytoplasm. Examples of cytoplasmic male sterility (CMS) were for instance described for Brassica species. However, genetic determinants for male sterility can also be located in the nuclear genome. Male-sterile plants can also be obtained by plant biotechnology methods such as genetic engineering. A particularly useful means of obtaining male-sterile plants is described in WO 89/10396 in which, for example, a ribonuclease such as a barnase is selectively expressed in the tapetum cells in the stamens. Fertility can then be restored by expression in the tapetum cells of a ribonuclease inhibitor such as barstar.

Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance.

Herbicide-tolerant plants are, for example, glyphosate-tolerant plants, i.e. plants which have been made tolerant to the herbicide glyphosate or salts thereof. For example, glyphosate-tolerant plants can be obtained by transforming the plant with a gene which encodes the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Examples of such EPSPS genes are the AroA gene (mutant CT7) of the bacterium Salmonella typhimurium, the CP4 gene of the bacterium Agrobacterium sp., the genes encoding a petunia EPSPS, a tomato EPSPS, or an Eleusine EPSPS. It can also be a mutated EPSPS. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxidoreductase enzyme. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate acetyl transferase enzyme. Glyphosate-tolerant plants can also be obtained by selecting plants with naturally-occurring mutations of the above-mentioned genes.

Other herbicide-resistant plants are for example plants that have been made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinothricin or glufosinate. Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant glutamine synthase enzyme that is resistant to inhibition. One such efficient detoxifying enzyme is, for example, an enzyme encoding a phosphinothricin acetyltransferase (for example the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinothricin acetyltransferase have been described.

Further herbicide-tolerant plants are also plants that have been made tolerant to the herbicides inhibiting the enzyme hydroxyphenylpyruvate dioxygenase (HPPD). Hydroxyphenylpyruvatedioxygenases are enzymes that catalyze the reaction in which para-hydroxyphenylpyruvate (HPP) is converted to homogentisate. Plants tolerant to HPPD inhibitors can be transformed with a gene encoding a naturally occurring resistant HPPD enzyme, or a gene encoding a mutated HPPD enzyme. Tolerance to HPPD inhibitors can also be obtained by transforming plants with genes encoding certain enzymes enabling the formation of homogentisate despite the inhibition of the native HPPD enzyme by the HPPD inhibitor. Tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate dehydrogenase in addition to a gene encoding an HPPD-tolerant enzyme.

Further herbicide-resistant plants are plants that have been made tolerant to acetolactate synthase (ALS) inhibitors. The known ALS inhibitors include, for example, sulfonylurea, imidazolinone, triazolopyrimidines, pyrimidinyl oxy(thio)benzoates and/or sulfonylaminocarbonyltriazolinone herbicides. Different mutations in the ALS enzyme (also known as acetohydroxy acid synthase, AHAS) are known to confer tolerance to different herbicides and groups of herbicides. The production of sulphonylurea-tolerant plants and imidazolinone-tolerant plants has been described in the international publication WO 1996/033270. Further sulphonylurea- and imidazolinone-tolerant plants have also been described, for example in WO 2007/024782.

Other plants tolerant to imidazolinone and/or sulphonylurea can be obtained by induced mutagenesis, by selection in cell cultures in the presence of the herbicide or by mutation breeding.

Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which can also be treated in accordance with the invention are insect-resistant transgenic plants, i.e. plants which have been made resistant to attack by certain target insects. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation which imparts such insect resistance.

In the present context, the term "insect-resistant transgenic plant" includes any plant containing at least one transgene comprising a coding sequence which encodes the following:

1. 1) an insecticidal crystal protein from Bacillus thuringiensis or an insecticidal portion thereof, such as the insecticidal crystal proteins compiled online at: http://www.lifesci.sussex.ac.uk/Home/Neil_Crickmore/Bt/, or insecticidal portions thereof, for example proteins of the Cry protein classes Cry1Ab, Cry1Ac, Cry1F, Cry2Ab, Cry3Ae or Cry3Bb or insecticidal portions thereof; or
2. 2) a crystal protein from Bacillus thuringiensis or a portion thereof which is insecticidal in the presence of a second other crystal protein as Bacillus thuringiensis or a portion thereof, such as the binary toxin made up of the Cy34 and Cy35 crystal proteins; or
3. 3) a hybrid insecticidal protein comprising parts of two different insecticidal crystal proteins from Bacillus thuringiensis, such as a hybrid of the proteins of 1) above or a hybrid of the proteins of 2) above, for example the Cry1A.105 protein produced by maize event MON98034 (WO 2007/027777); or
4. 4) a protein of any one of points 1) to 3) above wherein some, particularly 1 to 10, amino acids have been replaced by another amino acid to obtain a higher insecticidal activity to a target insect species, and/or to expand the range of target insect species affected, and/or because of changes induced in the encoding DNA during cloning or transformation, such as the Cry3Bb1 protein in maize events MON863 or MON88017, or the Cry3A protein in maize event MIR604; or
5. 5) an insecticidal secreted protein from Bacillus thuringiensis or Bacillus cereus, or an insecticidal portion thereof, such as the vegetative insecticidal proteins (VIP) listed at: http://www.lifesci.sussex.ac.uk/home/Neil_Crickmore/Bt/vip.html, for example proteins from the VIP3Aa protein class; or
6. 6) a secreted protein from Bacillus thuringiensis or Bacillus cereus which is insecticidal in the presence of a second secreted protein from Bacillus thuringiensis or B. cereus, such as the binary toxin made up of the VIP1A and VIP2A proteins;
7. 7) a hybrid insecticidal protein comprising parts from different secreted proteins from Bacillus thuringiensis or Bacillus cereus, such as a hybrid of the proteins in 1) above or a hybrid of the proteins in 2) above; or
8. 8) a protein of any one of points 1) to 3) above wherein some, particularly 1 to 10, amino acids have been replaced by another amino acid to obtain a higher insecticidal activity to a target insect species, and/or to expand the range of target insect species affected, and/or because of changes induced in the encoding DNA during cloning or transformation (while still encoding an insecticidal protein), such as the VIP3Aa protein in cotton event COT102.

Of course, insect-resistant transgenic plants, as used herein, also include any plant comprising a combination of genes encoding the proteins of any one of the abovementioned classes 1 to 8. In one embodiment, an insect-resistant plant contains more than one transgene encoding a protein of any one of the abovementioned classes 1 to 8, to expand the range of target insect species affected or to delay insect resistance development to the plants, by using different proteins insecticidal to the same target insect species but having a different mode of action, such as binding to different receptor binding sites in the insect.

Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are tolerant to abiotic stress factors. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance. Particularly useful stress-tolerant plants include the following:

1. a. plants which contain a transgene capable of reducing the expression and/or the activity of the poly(ADP-ribose)polymerase (PARP) gene in the plant cells or plants;
2. b. plants which contain a stress tolerance-enhancing transgene capable of reducing the expression and/or the activity of the PARG-encoding genes of the plants or plant cells;
3. c. plants which contain a stress tolerance-enhancing transgene coding for a plant-functional enzyme of the nicotinamide adenine dinucleotide salvage biosynthesis pathway, including nicotinamidase. nicotinate phosphoribosyltransferase, nicotinic acid mononucleotide adenyltransferase, nicotinamide adenine dinucleotide synthetase or nicotinamide phosphoribosyltransferase.

Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention show altered quantity, quality and/or storage stability of the harvested product and/or altered properties of specific ingredients of the harvested product such as:

1. 1) Transgenic plants which synthesize a modified starch which is altered with respect to its chemophysical traits, in particular the amylose content or the amylose/amylopectin ratio, the degree of branching, the average chain length, the distribution of the side chains, the viscosity behaviour, the gel resistance, the grain size and/or grain morphology of the starch in comparison to the synthesized starch in wild-type plant cells or plants, such that this modified starch is better suited for certain applications.
2. 2) Transgenic plants which synthesize non-starch carbohydrate polymers or which synthesize non-starch carbohydrate polymers with altered properties in comparison to wild-type plants without genetic modification. Examples are plants which produce polyfructose, especially of the inulin and levan type, plants which produce alpha-1,4-glucans, plants which produce alpha-1,6-branched alpha-1,4-glucans, and plants producing alteman.
3. 3) Transgenic plants which produce hyaluronan.

Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as cotton plants, with altered fibre characteristics. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such altered fibre characteristics, and include:

1. a) plants, such as cotton plants, which contain an altered form of cellulose synthase genes;
2. b) plants, such as cotton plants, which contain an altered form of rsw2 or rsw3 homologous nucleic acids;
3. c) plants, such as cotton plants, with an increased expression of sucrose phosphate synthase;
4. d) plants, such as cotton plants, with an increased expression of sucrose synthase;
5. e) plants, such as cotton plants, wherein the timing of the plasmodesmatal gating at the basis of the fibre cell is altered, for example through downregulation of fibre-selective β-1,3-glucanase;
6. f) plants, such as cotton plants, which have fibres with altered reactivity, for example through the expression of the N-acetylglucosaminetransferase gene including nodC and chitin synthase genes.

Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as oilseed rape or related Brassica plants, with altered oil profile characteristics. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such altered oil characteristics, and include:

1. a) plants, such as oilseed rape plants, which produce oil having a high oleic acid content;
2. b) plants, such as oilseed rape plants, which produce oil having a low linolenic acid content;
3. c) plants, such as oilseed rape plants, which produce oil having a low level of saturated fatty acids.

Particularly useful transgenic plants which may be treated according to the invention are plants which comprise one or more genes which encode one or more toxins, and are the transgenic plants which are sold under the following trade names: YIELD GARD® (for example corn, cotton, soybeans), KnockOut® (for example corn), BiteGard® (for example corn), BT-Xtra® (for example corn), StarLink® (for example corn), Bollgard® (cotton), Nucotn® (cotton), Nucotn 33B® (cotton), NatureGard® (for example corn), Protecta® and NewLeaf® (potato). Examples of herbicide-tolerant plants which should be mentioned are corn varieties, cotton varieties and soybean varieties which are available under the following trade names: Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya beans), Liberty Link® (tolerance to phosphinothricin, for example oilseed rape), IMI® (tolerance to imidazolinone) and SCS® (tolerance to sulphonylurea, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield (for example maize).

Particularly useful transgenic plants which may be treated according to the invention are plants containing transformation events, or a combination of transformation events, and that are listed for example in the databases for various national or regional regulatory agencies (see for example http://gmoinfo.jrc.it/gmp_browse.aspx and http://www.agbios.com/dbase.php).

The plants listed can be treated in accordance with the invention in a particularly advantageous manner with the compounds of the general formula (I) and/or the active ingredient mixtures according to the invention. The preferred ranges stated above for the active ingredients or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text.

The inventive active ingredients or compositions can thus be used to protect plants from attack by the pathogens mentioned for a certain period of time after treatment. The period for which protection is provided extends generally for 1 to 28 days, preferably for 1 to 14 days, particularly preferably for 1 to 10 days, very particularly preferably for 1 to 7 days after the treatment of the plants with the active ingredients, or for up to 200 days after a seed treatment.
