The present invention relates to heteroaryl compounds of formula (I) or a compound in the form of a stereoisomer, an agriculturally acceptable salt, a tautomer, an isotopic form, a N-oxide, a S-oxide, or a prodrug thereof; and the use of a compound of formula (I) and a compound of formula (II) or in the form of a stereoisomer, an agriculturally acceptable salt, a tautomer, an isotopic form, a N-oxide, a S-oxide, or a prodrug thereof, as an agrochemical fungicide. The in- vention further relates to agrochemical mixtures comprising at least one compound of formula (I); at least one further pesticidally active substance selected from the group consisting of herbicides, safeners, fungicides, insecticides, and plant growth regulators; and to agrochemical compositions comprising at least one such compound of the formula I and an auxiliary. Further encompassed by the present invention are methods for combating phytopathogenic harmful fungi, which meth- ods comprising the steps of treatment of the phytopathogenic fungi, the plant or the plant propa- gation material selected from seeds, roots, fruits, tubers, bulbs, rhizomes, shoots, sprouts and other parts of plants, including seedlings and young plants to be protected against fungal attack, stored materials or harvest, or alternately the locus or soil or soil substituents or surfaces there- from, with at least one compound of formula (I).

Fungal phyto pathogens infect many crops worldwide and therefore pose a serious threat to agriculture. The control of plant diseases and crop damage caused by fungal plant pathogens is extremely pertinent to achieve high crop yield and efficiency.

Natural products have garnered increasing focus in the discovery of agrochemicals as they can afford an opportunity to discover potential lead candidates with different biological activities and modes of action (Ming Zhi Zhang et al., Eur J. Med. Chem.53, 2012, 283-291).

Streptochlorin, an indole alkaloid produced by many species of marine actinomycetes, was first isolated as a new antibiotic in 1988 from the lipophilic extracts of the mycelium of a Strepto- myces species. Streptochlorin belongs to the class of naturally occurring 5-(3-indolyl) oxazoles, which also includes the natural product pimprinine. Streptochlorin has been claimed to have a variety of biological activities, such as antibiotic, antiallergic, antiangiogenic, anticancer, anti- tumor, antiproliferative, antityrosinase, antinematodal and pesticidal activity. Synthetic structural analogues of streptochlorin and pimprinine are known in the art to exhibit antifungal activity(Ming Zhi Zhang et al., Eur J. Med. Chem.92, 2015, 776-783).

US 2011207732 A1 discloses azaindole derivatives which are useful as medicaments. There is a continuous need for developing new fungicidal compounds which are effective in terms of activity spectrum, selectivity, sites of action, application rate, environmental safety and to retard or combat resistance development. In many cases, in particular at low application rates, the fungicidal activity of known fungicidal compounds is unsatisfactory

The inventors surprisingly found that the novel heteroaryl compounds of formula (I) have improved antifungal activity. The compounds are particularly effective as agrochemical fungicides and effective against a broad spectrum of phytopathogenic fungi. The compounds of formula (I) also effectively exhibit phytopathogenic fungal activity against pathogens which are resistant to complex 2 or complex 3 respiratory chain inhibitors. Accordingly, the present invention relates to the use of an heteroaryl compound of formula (I), wherein,

The compounds of formula (I) can be prepared according to methods or in analogy to standard techniques that are described in the state of art. The synthetic procedure utilises the starting materials that are either commercially available or that may be prepared according to conventional procedures starting from readily available compounds. General Procedure:

With due modification of the starting compounds, the compounds of formula I can be prepared by procedures as given in below schemes. Route 1:

Step 1: Halogenation

To a stirred solution of protected amino compound in a polar aprotic solvent such as DCE was added a halogenating agent portion wise at 0 ^o C– rt and stirred for 2-14 hrs at rt. After the com- pletion of the reaction, the mixture was washed with brine, aq. Na2SO3, dried over Na2SO4, fil- tered, concentrated and purified by column to obtain the desired halogenated product. Step 2: Coupling

To a mixture of th otic solvent such as dioxane or a polar aprotic solvent like Acetonitrile, DMF or THF or a solvent mixture such as Dioxane-water or CH ₃ CN-water was added the boronate ester/boronic acid and a base such as K ₂ CO ₃ in the same solvent.Then the Pd-catalyst such as Pd(dppf)Cl ₂ or similar was added to the reaction mixture and heated to higher temperatures for 4-16 hrs. Additional Pd-catalyst was added in case of incompletion of the reaction and the mixture was stirred for another 6-10 hrs. The reaction was monitored by TLC and LCMS. After the completion of the reaction, the mixture was concentrated and purified by column to obtain a cis and trans isomeric mixture of the coupled product.

Step 3: Cyclization

The coupled product from the previous step in aq. inorganic acid such as 2N HCl was refluxed for 2-10 hrs. Completion of the reaction was monitored by using TLC and LCMS. The mixture was then extracted with ethyl acetate, dried over Na ₂ SO ₄ , filtered, concentrated and purified by column chromatography to obtain the desired cyclized product. Route 2:

Step 1: Aldol condensation

To a polar protic solvent containing a base was added the aldehyde and the azide at at 0 C and then stirred for 4 -16 hrs. After this time the reaction mixture was concentrated to a slurry and dissolved in a polar aprotic solvent and NH4Cl(aq). The aqueous layer was extracted with EtOAc and the combined organic washings were dried (Na2SO4) and concentrated in vacuo. The crude product was purified by flash chromatography. Step 2: cyclization

Heat

A solution of above azi her tempetatures for 1-16 hrs, then cooled to room temperature and concentrated in vacuo to afford the crude product which was purified by column chromatography.

Subsequent functionalization of the ring:

Iodination

To a solution of pro t he 5,5-ring system in a polar aprotic solvent such as DMF or a protic solvent like methanol or a polar solvent mixture such as methanol-water system at rt was added the halogenating agent portion wise over a period of 15- 30 min. Reaction mixture was stirred for 2– 16 hrs at rt. The reaction progress was monitored by TLC and LCMS. After completion of the reaction, the solvent was evaporated and the residue was diluted in ethyl acetate and washed with H2O followed by brine wash. Organic layer was separated and dried over Na ₂ SO ₄ and concentrated to afford the crude compound which was used for the next step without further purification.

Protection of the (aza)indole or 5,5-ring NH group

To a solution of substituted (aza)indole in a polar aprotic solvent such as THF was added the base over period of 10 - 20 minutes at 0°C under an inert gas. Reaction mixture was stirred at the same temperature for 30 minutes and to this reaction mixture was added the halide of the protecting group (for example tosyl chloride) over a period of 15 minutes. Reaction was continued for 2– 16 hrs at rt and the completion was monitored by TLC and LCMS. Reaction mixture was cooled to 0°C and quenched with sat. NH4Cl solution and diluted with ethyl acetate. Organic layer was separated and washed first with water followed by a brine wash. Organic layer was dried over Na2SO4 and concentrated under vacuum. The crude compound was further purified by chro- matography or by trituration with ethyl acetate/heptane mixture. Coupling of halo(aza)indole/5,5-ring system with boronic acid/boronate ester:

ol- vent such as THF or DMF or solvent mixture (eg: Dioxane: H2O, 4:1) was added the boronic acid/boronate ester followed by the addition of a base at rt. The reaction mixture was degassed followed by addition of the palladium catalyst such as Pd(dppf)2Cl2 or similar other catalysts. Re- action mixture was heated at 110 ^o C for 2 - 14 hrs. The reaction completion was monitored by TLC and LCMS. Reaction mixture was cooled to rt, diluted with ethyl acetate and filtered through celite. Organic layer was separated and washed with water, followed by washing with brine. Organic layer was separated, dried over Na ₂ SO ₄ and concentrated to afford crude product which was further purified by chromatography to afford the pure compound.

N-deprotection:

A

The N-deprote ction p n the protecting group. Protecting group-free coupling:

To a solution of halo(aza)indole in a polar solvent such as DMF or THF /solvent mixture such as dioxane:water, was added boronic acid/boronate ester followed by the addition of a base at rt. The solution was degassed followed by the addition of Xphos-Pd-G2 or similar type of Pd- catalyst. Reaction mixture was heated at 110 ^o C for 2– 14 hrs. The reaction was monitored by TLC and LCMS. Reaction mixture was cooled to rt, diluted with ethyl acetate and filtered through celite. Organic layer was separated and washed with water, followed by washing with brine solu- tion. Organic layer was then dried over Na2SO4 and concentrated to afford crude product which was further purified by chromatography to afford pure compound. Fischer Indole synthesis route for the synthesis of Indole, azaindole or 5,5-ring products:

To or a aprotic solvent such as THF or an acid such as acetic acid was added the aldehyde or an acetal protected aldehyde (with any ring sized acetal) in the same solvent dropwise. Inorganic acids such as HCl or H ₂ SO ₄ or organic acids such as acetic acid in stoichiometric or catalytic amounts or even a mixture of of organic and inorganic acids was added to the reaction mixture and heated to reflux for 6-16 hrs. Reaction progress was monitored by TLC and LCMS. After completion of the reac- tion, solvent was evaporated and the residue was diluted in ethyl acetate and washed with H ₂ O followed by brine wash. Organic layer was separated and dried over Na ₂ SO ₄ and concentrated to afford the crude compound which was further purified by column chromatography.

Note: In some cases, the reaction of (hetero)arylhydrazine and (protected) aldehyde leads to the (hetero)arylhydrazone formation which does not react further. In such cases, the hydrazone was isolated and further taken in a polar protic solvent was added inorganic acids or organic acids or a mixture of acids in stoichiometric or catalytic amounts and heated to reflux for a further 6-16 hrs to obtain the expected cyclized product. Work-up and purification of the final product is the same as mentioned before.

Individual compounds of formula I can also be prepared by derivatisation of other compounds of formula I or the intermediates thereof.

If the synthesis yields mixtures of isomers, a separation is generally not necessarily required since in some cases the individual isomers can be interconverted during work-up for use or dur- ing application (for example under the action of light, acids or bases). Such conversions may also take place after use, for example in the treatment of plants in the treated plant, or in the harmful fungus to be controlled.

Moreover, they are suitable for controlling harmful fungi, which inter alia occur in wood or roots of plants.

The compounds I and the compositions according to the invention are particularly important in the control of a multitude of phytopathogenic fungi on various cultivated plants, such as cereals, e. g. wheat, rye, barley, triticale, oats or rice; beet, e. g. sugar beet or fodder beet; fruits, such as pomes, stone fruits or soft fruits, e. g. apples, pears, plums, peaches, almonds, cherries, straw- berries, raspberries, blackberries or gooseberries; leguminous plants, such as lentils, peas, alfalfa or soybeans; oil plants, such as rape, mustard, olives, sunflowers, coconut, cocoa beans, castor oil plants, oil palms, ground nuts or soybeans; cucurbits, such as squashes, cucumber or melons; fiber plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruits or mandarins; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, toma- toes, potatoes, cucurbits or paprika; lauraceous plants, such as avocados, cinnamon or camphor; energy and raw material plants, such as corn, soybean, rape, sugar cane or oil palm; corn; to- bacco; nuts; coffee; tea; bananas; vines (table grapes and grape juice grape vines); hop; turf; sweet leaf (also called Stevia); natural rubber plants or ornamental and forestry plants, such as flowers, shrubs, broad-leaved trees or evergreens, e. g. conifers; and on the plant propagation material, such as seeds, and the crop material of these plants.

The term "plant propagation material" is to be understood to denote all the generative parts of the plant such as seeds and vegetative plant material such as cuttings and tubers (e. g. potatoes), which can be used for the multiplication of the plant. This includes seeds, roots, fruits, tubers, bulbs, rhizomes, shoots, sprouts and other parts of plants, including seedlings and young plants, which are to be transplanted after germination or after emergence from soil. These young plants may also be protected before transplantation by a total or partial treatment by immersion or pour- ing.

Preferably, treatment of plant propagation materials with compounds I and compositions thereof, respectively, is used for controlling a multitude of fungi on cereals, such as wheat, rye, barley and oats; rice, corn, cotton and soybeans.

The term "cultivated plants" is to be understood as including plants which have been modified by breeding, mutagenesis or genetic engineering including but not limiting to agricultural biotech products on the market or in development (cf. http://cera-gmc.org/, see GM crop database therein). Genetically modified plants are plants, which genetic material has been so modified by the use of recombinant DNA techniques that under natural circumstances cannot readily be ob- tained by cross breeding, mutations or natural recombination. Typically, one or more genes have been integrated into the genetic material of a genetically modified plant in order to improve certain properties of the plant. Such genetic modifications also include but are not limited to targeted post-translational modification of protein(s), oligo- or polypeptides e. g. by glycosylation or poly- mer additions such as prenylated, acetylated or farnesylated moieties or PEG moieties.

Plants that have been modified by breeding, mutagenesis or genetic engineering, e. g. have been rendered tolerant to applications of specific classes of herbicides, such as auxin herbicides such as dicamba or 2,4-D; bleacher herbicides such as hydroxylphenylpyruvate dioxygenase (HPPD) inhibitors or phytoene desaturase (PDS) inhibitors; acetolactate synthase (ALS) inhibitors such as sulfonyl ureas or imidazolinones; enolpyruvylshikimate-3-phosphate synthase (EPSPS) inhib- itors, such as glyphosate; glutamine synthetase (GS) inhibitors such as glufosinate; protoporphy- rinogen-IX oxidase inhibitors; lipid biosynthesis inhibitors such as acetyl CoA carboxylase (AC- Case) inhibitors; or oxynil (i. e. bromoxynil or ioxynil) herbicides as a result of conventional meth- ods of breeding or genetic engineering. Furthermore, plants have been made resistant to multiple classes of herbicides through multiple genetic modifications, such as resistance to both glypho- sate and glufosinate or to both glyphosate and a herbicide from another class such as ALS inhib- itors, HPPD inhibitors, auxin herbicides, or ACCase inhibitors. These herbicide resistance tech- nologies are e. g. described in Pest Managem. Sci.61, 2005, 246; 61, 2005, 258; 61, 2005, 277; 61, 2005, 269; 61, 2005, 286; 64, 2008, 326; 64, 2008, 332; Weed Sci.57, 2009, 108; Austral. J. Agricult. Res.58, 2007, 708; Science 316, 2007, 1185; and references quoted therein. Several cultivated plants have been rendered tolerant to herbicides by conventional methods of breeding (mutagenesis), e. g. Clearfield ^® summer rape (Canola, BASF SE, Germany) being tolerant to imidazolinones, e. g. imazamox, or ExpressSun ^® sunflowers (DuPont, USA) being tolerant to sul- fonyl ureas, e. g. tribenuron. Genetic engineering methods have been used to render cultivated plants such as soybean, cotton, corn, beets and rape, tolerant to herbicides such as glyphosate and glufosinate, some of which are commercially available under the trade names Round- upReady ^® (glyphosate-tolerant, Monsanto, U.S.A.), Cultivance ^® (imidazolinone tolerant, BASF SE, Germany) and LibertyLink ^® (glufosinate-tolerant, Bayer CropScience, Germany).

Furthermore, plants are also covered that are by the use of recombinant DNA techniques capable to synthesize one or more insecticidal proteins, especially those known from the bacterial genus Bacillus, particularly from Bacillus thuringiensis, such as δ-endotoxins, e. g. CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c; vegetative insecticidal proteins (VIP), e. g. VIP1, VIP2, VIP3 or VIP3A; insecticidal proteins of bacteria colonizing nematodes, e. g. Photorhabdus spp. or Xenorhabdus spp.; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins, or other insect-specific neurotoxins; toxins produced by fungi, such Streptomycetes toxins, plant lectins, such as pea or barley lectins; agglutinins; proteinase inhibi- tors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin or papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroid oxidase, ecdysteroid-IDP-glycosyl-trans- ferase, cholesterol oxidases, ecdysone inhibitors or HMG-CoA-reductase; ion channel blockers, such as blockers of sodium or calcium channels; juvenile hormone esterase; diuretic hormone receptors (helicokinin receptors); stilbene synthase, bibenzyl synthase, chitinases or glucanases. In the context of the present invention these insecticidal proteins or toxins are to be understood expressly also as pre-toxins, hybrid proteins, truncated or otherwise modified proteins. Hybrid proteins are characterized by a new combination of protein domains, (see, e. g. WO 02/015701). Further examples of such toxins or genetically modified plants capable of synthesizing such toxins are disclosed, e. g., in EP-A 374753, WO 93/007278, WO 95/34656, EP-A 427529, EP-A 451878, WO 03/18810 und WO 03/52073. The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e. g. in the publications mentioned above. These insecticidal proteins contained in the genetically modified plants impart to the plants producing these proteins tolerance to harmful pests from all taxonomic groups of arthropods, especially to beetles (Coeloptera), two-winged insects (Diptera), and moths (Lepidoptera) and to nematodes (Nematoda). Genetically modified plants capable to synthesize one or more insecticidal proteins are, e. g., described in the publications mentioned above, and some of which are commercially available such as YieldGard ^® (corn cultivars producing the Cry1Ab toxin), YieldGard ^® Plus (corn cultivars producing Cry1Ab and Cry3Bb1 toxins), Starlink ^® (corn cultivars producing the Cry9c toxin), Herculex ^® RW (corn cultivars producing Cry34Ab1, Cry35Ab1 and the enzyme phosphinothricin-N-acetyltransferase [PAT]); NuCOTN ^® 33B (cotton cultivars producing the Cry1Ac toxin), Bollgard ^® I (cotton cultivars producing the Cry1Ac toxin), Bollgard ^® II (cotton cultivars producing Cry1Ac and Cry2Ab2 toxins); VIPCOT ^® (cotton cultivars producing a VIP-toxin); NewLeaf ^® (potato cultivars producing the Cry3A toxin); Bt-Xtra ^® , Nature- Gard ^® , KnockOut ^® , BiteGard ^® , Protecta ^® , Bt11 (e. g. Agrisure ^® CB) and Bt176 from Syngenta Seeds SAS, France, (corn cultivars producing the Cry1Ab toxin and PAT enyzme), MIR604 from Syngenta Seeds SAS, France (corn cultivars producing a modified version of the Cry3A toxin, c.f. WO 03/018810), MON 863 from Monsanto Europe S.A., Belgium (corn cultivars producing the Cry3Bb1 toxin), IPC 531 from Monsanto Europe S.A., Belgium (cotton cultivars producing a mod- ified version of the Cry1Ac toxin) and 1507 from Pioneer Overseas Corporation, Belgium (corn cultivars producing the Cry1F toxin and PAT enzyme).

Furthermore, plants are also covered that are by the use of recombinant DNA techniques capable to synthesize one or more proteins to increase the resistance or tolerance of those plants to bac- terial, viral or fungal pathogens. Examples of such proteins are the so-called“pathogenesis-re- lated proteins” (PR proteins, see, e. g. EP-A 392225), plant disease resistance genes (e. g. po- tato cultivars, which express resistance genes acting against Phytophthora infestans derived from the Mexican wild potato Solanum bulbocastanum) or T4-lysozym (e. g. potato cultivars capable of synthesizing these proteins with increased resistance against bacteria such as Erwinia amyl- vora). The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e. g. in the publications mentioned above.

Furthermore, plants are also covered that are by the use of recombinant DNA techniques capable to synthesize one or more proteins to increase the productivity (e. g. bio mass production, grain yield, starch content, oil content or protein content), tolerance to drought, salinity or other growth- limiting environmental factors or tolerance to pests and fungal, bacterial or viral pathogens of those plants.

Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of substances of content or new substances of content, specifically to improve human or animal nutrition, e. g. oil crops that produce health-promoting long-chain omega-3 fatty acids or unsaturated omega-9 fatty acids (e. g. Nexera ^® rape, DOW Agro Sciences, Canada). Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of substances of content or new substances of content, specifically to improve raw material production, e. g. potatoes that produce increased amounts of amylopectin (e. g. Am- flora ^® potato, BASF SE, Germany).

In a preferred embodiment the compounds I and compositions thereof, respectively, are particu- larly suitable for controlling the following plant diseases: Puccinia spp. (rusts) on various plants, for example, but not limited to P. triticina (brown or leaf rust), P. striiformis (stripe or yellow rust), P. hordei (dwarf rust), P. graminis (stem or black rust) or P. recondita (brown or leaf rust) on cereals, such as e. g. wheat, barley or rye and Phakopsoraceae spp. on various plants, in partic- ular Phakopsora pachyrhizi and P. meibomiae (soybean rust) on soybeans.

The compounds I and compositions thereof, respectively, are also suitable for controlling harmful fungi in the protection of stored products or harvest and in the protection of materials.

The term "protection of materials" is to be understood to denote the protection of technical and non-living materials, such as adhesives, glues, wood, paper and paperboard, textiles, leather, paint dispersions, plastics, cooling lubricants, fiber or fabrics, against the infestation and destruc- tion by harmful microorganisms, such as fungi and bacteria. As to the protection of wood and other materials, the particular attention is paid to the following harmful fungi: Ascomycetes such as Ophiostoma spp., Ceratocystis spp., Aureobasidium pullulans, Sclerophoma spp., Chaeto- mium spp., Humicola spp., Petriella spp., Trichurus spp.; Basidiomycetes such as Coniophora spp., Coriolus spp., Gloeophyllum spp., Lentinus spp., Pleurotus spp., Poria spp., Serpula spp. and Tyromyces spp., Deuteromycetes such as Aspergillus spp., Cladosporium spp., Penicillium spp., Trichoderma spp., Alternaria spp., Paecilomyces spp. and Zygomycetes such as Mucor spp., and in addition in the protection of stored products and harvest the following yeast fungi are worthy of note: Candida spp. and Saccharomyces cerevisae.

The method of treatment according to the invention can also be used in the field of protecting stored products or harvest against attack of fungi and microorganisms. According to the present invention, the term "stored products" is understood to denote natural substances of plant or animal origin and their processed forms, which have been taken from the natural life cycle and for which long-term protection is desired. Stored products of crop plant origin, such as plants or parts thereof, for example stalks, leafs, tubers, seeds, fruits or grains, can be protected in the freshly harvested state or in processed form, such as pre-dried, moistened, comminuted, ground, pressed or roasted, which process is also known as post-harvest treatment. Also falling under the definition of stored products is timber, whether in the form of crude timber, such as construction timber, electricity pylons and barriers, or in the form of finished articles, such as furniture or objects made from wood. Stored products of animal origin are hides, leather, furs, hairs and the like. The combinations according the present invention can prevent disadvantageous effects such as de- cay, discoloration or mold. Preferably "stored products" is understood to denote natural sub- stances of plant origin and their processed forms, more preferably fruits and their processed forms, such as pomes, stone fruits, soft fruits and citrus fruits and their processed forms.

The compounds of formula I can be present in different crystal modifications whose biological activity may differ. They are likewise subject matter of the present invention.

The compounds I are employed as such or in form of compositions by treating the fungi or the plants, plant propagation materials, such as seeds, soil, surfaces, materials or rooms to be pro- tected from fungal attack with a fungicidally effective amount of the active substances. The appli- cation can be carried out both before and after the infection of the plants, plant propagation ma- terials, such as seeds, soil, surfaces, materials or rooms by the fungi.

Plant propagation materials may be treated with compounds I as such or a composition compris- ing at least one compound I prophylactically either at or before planting or transplanting.

The invention also relates to agrochemical compositions comprising an auxiliary and at least one compound I according to the invention.

An agrochemical composition comprises a fungicidally effective amount of a compound I. The term "effective amount" denotes an amount of the composition or of the compounds I, which is sufficient for controlling harmful fungi on cultivated plants or in the protection of materials and which does not result in a substantial damage to the treated plants. Such an amount can vary in a broad range and is dependent on various factors, such as the fungal species to be controlled, the treated cultivated plant or material, the climatic conditions and the specific compound I used. The compounds (I), their N-oxides and salts can be converted into customary types of agrochem- ical compositions, e. g. solutions, emulsions, suspensions, dusts, powders, pastes, granules, pressings, capsules, and mixtures thereof. Examples for composition types are suspensions (e. g. SC, OD, FS), emulsifiable concentrates (e. g. EC), emulsions (e. g. EW, EO, ES, ME), capsules (e. g. CS, ZC), pastes, pastilles, wettable powders or dusts (e. g. WP, SP, WS, DP, DS), pressings (e. g. BR, TB, DT), granules (e. g. WG, SG, GR, FG, GG, MG), insecticidal articles (e. g.

In an agitated ball mill, 5-25 wt% of a compound I are comminuted with addition of 3-10 wt% dispersants (e. g. sodium lignosulfonate), 1-5 wt% thickener (e. g. carboxymethyl cellulose) and water ad 100 wt% to give a fine suspension of the active substance. Dilution with water gives a stable suspension of the active substance.

ix) Microemulsion (ME)

5-20 wt% of a compound I are added to 5-30 wt% organic solvent blend (e. g. fatty acid dimethyl amide and cyclohexanone), 10-25 wt% surfactant blend (e. g. alcohol ethoxylate and arylphenol ethoxylate), and water ad 100 %. This mixture is stirred for 1 h to produce spontaneously a ther- modynamically stable microemulsion.

x) Microcapsules (CS)

An oil phase comprising 5-50 wt% of a compound I, 0-40 wt% water insoluble organic solvent (e. g. aromatic hydrocarbon), 2-15 wt% acrylic monomers (e. g. methylmethacrylate, methacrylic acid and a di- or triacrylate) are dispersed into an aqueous solution of a protective colloid (e. g. poly- vinyl alcohol). Radical polymerization results in the formation of poly(meth)acrylate microcap- sules. Alternatively, an oil phase comprising 5-50 wt% of a compound I according to the invention, 0-40 wt% water insoluble organic solvent (e. g. aromatic hydrocarbon), and an isocyanate mon- omer (e. g. diphenylmethene-4,4’-diisocyanatae) are dispersed into an aqueous solution of a pro- tective colloid (e. g. polyvinyl alcohol). The addition of a polyamine (e. g. hexamethylenediamine) results in the formation of polyurea microcapsules. The monomers amount to 1-10 wt%. The wt% relate to the total CS composition.

xi) Dustable powders (DP, DS)

1-10 wt% of a compound I are ground finely and mixed intimately with solid carrier (e. g. finely divided kaolin) ad 100 wt%.

xiii) Ultra-low volume liquids (UL)

1-50 wt% of a compound I are dissolved in organic solvent (e. g. aromatic hydrocarbon) ad 100 wt%.

The compositions types i) to xiii) may optionally comprise further auxiliaries, such as 0.1-1 wt% bactericides, 5-15 wt% anti-freezing agents, 0.1-1 wt% anti-foaming agents, and 0.1-1 wt% col- orants. The agrochemical compositions generally comprise between 0.01 and 95%, preferably between 0.1 and 90%, more preferably between 1 and 70%, and in particular between 10 and 60%, by weight of active substance. The active substances are employed in a purity of from 90% to 100%, preferably from 95% to 100% (according to NMR spectrum).

For the purposes of treatment of plant propagation materials, particularly seeds, solutions for seed treatment (LS), Suspoemulsions (SE), flowable concentrates (FS), powders for dry treatment (DS), water-dispersible powders for slurry treatment (WS), water-soluble powders (SS), emul- sions (ES), emulsifiable concentrates (EC), and gels (GF) are usually employed. The composi- tions in question give, after two-to-tenfold dilution, active substance concentrations of from 0.01 to 60% by weight, preferably from 0.1 to 40%, in the ready-to-use preparations. Application can be carried out before or during sowing. Methods for applying compound I and compositions thereof, respectively, onto plant propagation material, especially seeds, include dressing, coating, pelleting, dusting, and soaking as well as in-furrow application methods. Preferably, compound I or the compositions thereof, respectively, are applied on to the plant propagation material by a method such that germination is not induced, e. g. by seed dressing, pelleting, coating and dust- ing. When employed in plant protection, the amounts of active substances applied are, depending on the kind of effect desired, from 0.001 to 2 kg per ha, preferably from 0.005 to 2 kg per ha, more preferably from 0.05 to 0.9 kg per ha, and in particular from 0.1 to 0.75 kg per ha.

In treatment of plant propagation materials such as seeds, e. g. by dusting, coating or drenching seed, amounts of active substance of from 0.1 to 1000 g, preferably from 1 to 1000 g, more preferably from 1 to 100 g and most preferably from 5 to 100 g, per 100 kilogram of plant propa- gation material (preferably seeds) are generally required.

When used in the protection of materials or stored products, the amount of active substance applied depends on the kind of application area and on the desired effect. Amounts customarily applied in the protection of materials are 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active substance per cubic meter of treated material.

Various types of oils, wetters, adjuvants, fertilizer, or micronutrients, and further pesticides (e. g. herbicides, insecticides, fungicides, growth regulators, safeners, biopesticides) may be added to the active substances or the compositions comprising them as premix or, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the compositions accord- ing to the invention in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.

A pesticide is generally a chemical or biological agent (such as pestidal active ingredient, com- pound, composition, virus, bacterium, antimicrobial or disinfectant) that through its effect deters, incapacitates, kills or otherwise discourages pests. Target pests can include insects, plant path- ogens, weeds, mollusks, birds, mammals, fish, nematodes (roundworms), and microbes that de- stroy property, cause nuisance, spread disease or are vectors for disease. The term“pesticide” includes also plant growth regulators that alter the expected growth, flowering, or reproduction rate of plants; defoliants that cause leaves or other foliage to drop from a plant, usually to facilitate harvest; desiccants that promote drying of living tissues, such as unwanted plant tops; plant acti- vators that activate plant physiology for defense of against certain pests; safeners that reduce unwanted herbicidal action of pesticides on crop plants; and plant growth promoters that affect plant physiology e.g. to increase plant growth, biomass, yield or any other quality parameter of the harvestable goods of a crop plant.

The user applies the composition according to the invention usually from a predosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. Usually, the agrochemical composition is made up with water, buffer, and/or further auxiliaries to the desired application concentration and the ready-to-use spray liquor or the agrochemical composition according to the invention is thus obtained. Usually, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to- use spray liquor are applied per hectare of agricultural useful area.

According to one embodiment, individual components of the composition according to the inven- tion such as parts of a kit or parts of a binary or ternary mixture may be mixed by the user himself in a spray tank or any other kind of vessel used for applications (e. g. seed treater drums, seed pelleting machinery, knapsack sprayer) and further auxiliaries may be added, if appropriate. Consequently, one embodiment of the invention is a kit for preparing a usable pesticidal compo- sition, the kit comprising a) a composition comprising component 1) as defined herein and at least one auxiliary; and b) a composition comprising component 2) as defined herein and at least one auxiliary; and optionally c) a composition comprising at least one auxiliary and optionally a further active component 3) as defined herein.

Mixing the compounds (I) or the compositions comprising them in the use form as fungicides with other fungicides results in many cases in an expansion of the fungicidal spectrum of activity being obtained or in a prevention of fungicide resistance development. Furthermore, in many cases, synergistic effects are obtained.

The present invention furthermore relates to agrochemical compositions comprising a mixture of at least one compound I (component 1) and at least one further active substance useful for plant protection, e. g. selected from the groups A) to O) (component 2), and if desired one suitable solvent or solid carrier. Furthermore, combating harmful fungi with a mixture of compounds of formula (I) and at least one fungicide from groups A) to O), as described above, is more efficient than combating those fungi with individual compounds (I) or individual fungicides from groups A) to O).

By applying compounds of formula (I) together with at least one active substance from groups A) to O) a synergistic effect can be obtained, i.e. more then simple addition of the individual effects is obtained (synergistic mixtures).

This can be obtained by applying the compounds (I) and at least one further active substance simultaneously, either jointly (e. g. as tank-mix) or seperately, or in succession, wherein the time interval between the individual applications is selected to ensure that the active substance applied first still occurs at the site of action in a sufficient amount at the time of application of the further active substance(s). The order of application is not essential for working of the present invention. When applying compound I and a pesticide II sequentially the time between both applications may vary e. g. between 2 hours to 7 days. Also a broader range is possible ranging from 0.25 hour to 30 days, preferably from 0.5 hour to 14 days, particularly from 1 hour to 7 days or from 1.5 hours to 5 days, even more preferred from 2 hours to 1 day.

In the binary mixtures and compositions according to the invention the weight ratio of the compo- nent 1) and the component 2) generally depends from the properties of the active components used, usually it is in the range of from 1:10,000 to 10,000:1, often it is in the range of from 1:100 to 100:1, regularly in the range of from 1:50 to 50:1, preferably in the range of from 1:20 to 20:1, more preferably in the range of from 1:10 to 10:1, even more preferably in the range of from 1:4 to 4:1 and in particular in the range of from 1:2 to 2:1.

According to further embodiments of the binary mixtures and compositions, the weight ratio of the component 1) and the component 2) usually is in the range of from 1000:1 to 1:1, often in the range of from 100: 1 to 1:1, regularly in the range of from 50:1 to 1:1, preferably in the range of from 20:1 to 1:1, more preferably in the range of from 10:1 to 1:1, even more preferably in the range of from 4:1 to 1:1 and in particular in the range of from 2:1 to 1:1.

According to a further embodiments of the binary mixtures and compositions, the weight ratio of the component 1) and the component 2) usually is in the range of from 1:1 to 1:1000, often in the range of from 1:1 to 1:100, regularly in the range of from 1:1 to 1:50, preferably in the range of from 1:1 to 1:20, more preferably in the range of from 1:1 to 1:10, even more preferably in the range of from 1:1 to 1:4 and in particular in the range of from 1:1 to 1:2.

In the ternary mixtures, i.e. compositions according to the invention comprising the component 1) and component 2) and a compound III (component 3), the weight ratio of component 1) and com- ponent 2) depends from the properties of the active substances used, usually it is in the range of from 1:100 to 100:1, regularly in the range of from 1:50 to 50:1, preferably in the range of from 1:20 to 20:1, more preferably in the range of from 1:10 to 10:1 and in particular in the range of from 1:4 to 4:1, and the weight ratio of component 1) and component 3) usually it is in the range of from 1:100 to 100:1, regularly in the range of from 1:50 to 50:1, preferably in the range of from 1:20 to 20:1, more preferably in the range of from 1:10 to 10:1 and in particular in the range of from 1:4 to 4:1.

Any further active components are, if desired, added in a ratio of from 20:1 to 1:20 to the compo- nent 1).
