Title of the Invention: 1,2,3-TRIAZOLE CARBONYL SULFONYLAMIDES COMPOUNDS AND USE THEREOF FIELD OF THE INVENTION The present invention relates to novel nematicidal compounds of formula (I). More particularly, the present invention relates to novel 1,2,3-triazole carbonyl sulfonylamide compounds of formula (I) and a process for the preparation thereof. The present invention further relates to a composition and a combination comprising such novel 1,2,3-triazole carbonyl sulfonylamide compounds, and to their use as crop protection agents for the control of pests such as plant parasitic nematodes. BACKGROUND OF THE INVENTION The control of damages to plants caused by phytopathogenic microorganisms and animal pests, in particular plant-parasitic nematodes, is extremely important to achieve high crop efficiency. Nematodes cause a substantial loss in agricultural food and industrial crops, and are therefore combated with chemical compounds having nematicidal activity. Even though many products are commercially available to control such damage, the need continues for new compounds which are more effective, less toxic, less costly, environmentally safer and/or have a different mode of action. In the literature, sulfonylamides and their suitability as agrochemicals are described. For example, patent application EP0244166 discloses fused triazole acyl sulfonamides as herbicides and/or plant growth regulators. Further prior art documents WO2010/129500, WO2012/054233 and WO2015/169776 describe fused imidazolopyridine acyl sulfonamide compounds that allow the controlling of harmful nematodes. In addition to the above prior art documents, WO2017157735 and WO2018/083288 discloses disubstituted pyrazole/imidazole acyl sulfonylamides that can be used as nematicides. Under agricultural conditions, the effectiveness of the substituted sulfonylamides, described in the prior art, is not fully satisfactory in various aspects such as nematicidal activity, application rates, treatment cost and toxicity. Therefore, it is always of high interest to find novel pesticidal compounds for the control of pests such as nematodes with better economical and environmental properties. The aim is to provide novel compounds being more active at lower application rates and environmentally safer whilst at the same time maintaining an effectiveness, long lasting activity and environmental and human health related compatibility, at least in an equivalent or if possible improved way compared to the already known compounds. The present invention describes compounds of formula (I) which display the above - mentioned effects or advantages. Compounds of formula (I) are fulfilling this purpose, namely novel 1,2,3- triazole carbonyl sulfonylamide compounds with a substituted heterocyclic ring, by exhibiting surprisingly significant higher activity levels against undesired pests such as phytoparasitic nematodes. SUMMARY OF THE INVENTION The present invention provides novel 1,2,3-triazole carbonyl sulfonylamide compounds of formula (I), Formula (I) wherein, R ¹ , R ² and Z are as defined in the detailed description. In one embodiment, the present invention provides a process for preparing the compounds of formula (I). In another embodiment, the present invention provides a composition for controlling or preventing phytoparasitic organisms such as nematodes comprising a biologically effective amount of a compound of formula (I) or salts, stereoisomers, polymorphs or N-oxides thereof and at least one additional component selected from the group consisting of surfactants and auxiliaries. In yet another embodiment, the composition further comprises at least one additional biologically active and compatible compound selected from fungicides, insecticides, nematicides, acaricides, biopesticides, herbicides, plant growth regulators, antibiotics, fertilizers or nutrients. In still another embodiment, the present invention provides the use of the compounds of formula (I) or salts, stereoisomers, polymorphs or N-oxides, compositions or combinations thereof, for the control of phytoparasitic organisms such as nematodes. In yet still another embodiment, the present invention provides a method of combating phytoparasitic organisms such as nematodes with a biologically effective amount of the compounds of formula (I) or salts, stereoisomers, polymorphs or N-oxides thereof as well as compositions or combinations thereof. DETAILED DESCRIPTION OF THE INVENTION: Definitions: The terminologies used in the present disclosure are for illustrative purposes only and in no manner limit the scope of the present invention disclosed in the present disclosure. As used herein, the terms “comprises”, “comprising”, “includes”, “including”, “has”, “having”, “contains”, “containing”, “characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method. The transitional phrase “consisting of” excludes any element, step or ingredient not specified. If in the claim, such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole. Further, unless expressly stated to the contrary, “or” refers to an inclusive “or” and not to an exclusive “or”. For example, a condition A “or” B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). Also, the indefinite articles “a” and “an” preceding an element or component of the present invention are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular. As referred to in this disclosure, the term “pesticide” in each case also always comprises the term “crop protection agent”. The term “invertebrate pest” includes arthropods, gastropods and nematodes of economic importance as pests. The term “arthropod” includes insects, mites, spiders, scorpions, centipedes, millipedes, pill bugs and symphylans. The term “gastropod” includes snails, slugs and other Stylommatophora. The term “nematode” refers to a living organism of the Phylum Nematoda. The term “helminths” includes roundworms, heartworms, phytophagous nematodes (Nematoda), flukes (Trematoda), acanthocephala and tapeworms (Cestoda). In the context of this disclosure “invertebrate pest control” means inhibition of invertebrate pest development (including mortality, feeding reduction, and/or mating disruption), and related expressions are defined analogously. The term “agronomic” refers to the production of field crops such as for food and fiber and includes the growth of corn, soybeans and other legumes, rice, cereal (e.g., wheat, oats, barley, rye, rice, maize), leafy vegetables (e.g., lettuce, cabbage, and other cole crops), fruiting vegetables (e.g., tomatoes, pepper, eggplant, crucifers and cucurbits), potatoes, sweet potatoes, grapes, cotton, tree fruits (e.g., pome, stone and citrus), small fruit (berries, cherries) and other specialty crops (e.g., canola, sunflower, olives). The term “nonagronomic” refers to other than field crops, such as horticultural crops (e.g., greenhouse, nursery or ornamental plants not grown in a field), residential, agricultural, commercial and industrial structures, turf (e.g., sod farm, pasture, golf course, lawn, sports field, etc.), wood products, stored product, agro-forestry and vegetation management, public health (i.e. human) and animal health (e.g., domesticated animals such as pets, livestock and poultry, undomesticated animals such as wildlife) applications. Nonagronomic applications include protecting an animal from an invertebrate parasitic pest by administering a parasiticidally effective (i.e. biologically effective) amount of a compound of the present invention, typically in the form of a composition formulated for veterinary use, to the animal to be protected. As referred to in the present disclosure and claims, the terms “parasiticidal” and “parasiticidally” refers to observable effects on an invertebrate parasite pest to provide protection of an animal from the pest. Parasiticidal effects typically relate to diminishing the occurrence or activity of the target invertebrate parasitic pest. Such effects on the pest include necrosis, death, retarded growth, diminished mobility, or lessened ability to remain on or in the host animal, reduced feeding and inhibition of reproduction. These effects on invertebrate parasite pests provide control (including prevention, reduction, or elimination) of a parasitic infestation or infection of the animal. The term “stereoisomer” refers to isomers of the same configuration that differ in the arrangement of atoms in space. Enantiomers and diastereomers are examples of stereoisomers. The term "enantiomer" refers to a pair of molecular species that are mirror images of each other and are not superimposed. The term “diastereomer” refers to a stereoisomer that is not a mirror image. The term “racemate” or “racemic mixture” refers to a composition consisting of an equimolar amount of two enantiomeric species, wherein the composition is not optically active. The compounds of the present disclosure may be present either in pure form or as mixtures of different possible isomeric forms such as stereoisomers or constitutional isomers. The various stereoisomers include enantiomers, diastereomers, chiral isomers, atropisomers, conformers, rotamers, tautomers, optical isomers, polymorphs, and geometric isomers. Any desired mixtures of these isomers fall within the scope of the claims of the present disclosure. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other isomer(s) or when separated from the other isomer(s). Additionally, the person skilled in the art knows processes or methods or technology to separate, enrich, and/or to selectively prepare said isomers.

One skilled in the art will appreciate that not all nitrogen-containing heterocycles can form N- oxides since the nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen-containing heterocycles which can form N-oxides. One skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for the preparation of N-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and 3-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature, see for example: TL Gilchrist in Comprehensive Organic Synthesis, vol.7, pp 748–750. The term “amide” means A-R'C=ONR''-B, wherein R' and R'' indicates substituents and A and B indicate any group. The term “thioamide” means A-R'C=SNR''-B, wherein R' and R'' indicates substituents and A and B indicate any group. The term "leaving group (LG)" means, all substituents which have sufficient nucleofilicity under the prevailing reaction conditions or a nucleophilically replaceable group; by way of example, halogens (chloro, iodo, bromo), triflate, nosylate, mesylate, tosylate or SCh-Me may be mentioned as suitable leaving groups Examples for illustrating "C _i -C _j -cycloalkyl-C _i -C _j -alkyl" includes but are not limited to cyclopropyl-methyl, cyclopropyl-ethyl, cyclobutyl-methyl, cyclobutyl-ethyl, cyclopentyl- methyl and cyclopentyl-ethyl. The total number of carbon atoms in a substituent group is indicated by the “Ci-Cj” prefix where i and j are numbers from 1 to 21. For example, C1-C4 alkoxy designates methoxy through butyloxy. In the above recitations, when a compound of formula (I) is comprised of one or more heterocyclic rings, all substituents are attached to these rings through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen. When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e. g. (R)i-j, then the number of substituents may be selected from the integers between i and j inclusive. When a group contains a substituent which can be hydrogen, for example R ¹ or R ² , then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted.

The cationic surfactants are, especially, quarternary ammonium salts which generally have at least one alkyl radical of approximately 8 to approximately 22 Carbon atoms as substituents and as further substituents (unhalogenated or halogenated) lower alkyl or hydroxyalkyl or benzyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples are stearyltrimethylammonium chloride and benzylbis(2-chloroethyl)ethylammonium bromide. Examples of suitable anionic surfactants are water-soluble soaps or water-soluble synthetic surface-active compounds. Examples of suitable soaps are the alkali, alkaline earth or (unsubstituted or substituted) ammonium salts of fatty acids having approximately 10 to approximately 22 Carbon atoms, such as the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which are obtainable for example from coconut or tall oil; mention must also be made of the fatty acid methyl taurates. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. As a rule, the fatty sulfonates and fatty sulfates are present as alkali, alkaline earth or (substituted or unsubstituted) ammonium salts and they generally have an alkyl radical of approximately 8 to approximately 22 Carbon atoms, alkyl also to be understood as including the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium or calcium salts of lignosulfonic acid, of the dodecylsulphuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulphuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonyl groups and a fatty acid radical of approximately 8 to approximately 22 Carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of decylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensate. Also possible are, furthermore, suitable phosphates, such as salts of the phosphoric ester of a p-nonylphenol/(4-14)ethylene oxide adduct, or phospholipids. As a rule, the compositions comprise 0.1 to 99%, especially 0.1 to 95%, of a compound according to the present invention and 1 to 99.9%, especially 5 to 99.9%, of at least one solid or liquid carrier, it being possible as a rule for 0 to 25%, especially 0.1 to 20%, of the composition to be surfactants (% in each case meaning percent by weight). Whereas concentrated compositions tend to be preferred for commercial goods, the end consumer as a rule uses dilute compositions which have substantially lower concentrations of active ingredient. Examples of foliar formulation types for pre-mix compositions are: Whereas, examples of seed treatment formulation types for pre-mix compositions are: Examples of formulation types suitable for tank-mix compositions are solutions, dilute emulsions, suspensions, or a mixture thereof, and dusts. As with the nature of the formulations, the methods of application, such as foliar, drench, spraying, atomizing, dusting, scattering, coating, or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The tank-mix compositions are generally prepared by diluting with a solvent (for example, water) the one or more pre-mix compositions containing different pesticides, and optionally further auxiliaries. Suitable carriers and adjuvants can be solid or liquid and are the substances ordinarily employed in formulation technology, e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilizers. Generally, a tank-mix formulation for foliar or soil application comprises 0.1 to 20%, especially 0.1 to 15%, of the desired ingredients, and 99.9 to 80%, especially 99.9 to 85%, of a solid or liquid auxiliary (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 20%, especially 0.1 to 15%, based on the tank-mix formulation. Typically, a pre-mix formulation for foliar application comprises 0.1 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.9 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation. Normally, a tank-mix formulation for seed treatment application comprises 0.25 to 80%, especially 1 to 75%, of the desired ingredients, and 99.75 to 20%, especially 99 to 25%, of a solid or liquid auxiliary (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 40%, especially 0.5 to 30%, based on the tank-mix formulation. Typically, a pre-mix formulation for seed treatment application comprises 0.5 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.5 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation whereas commercial products will preferably be formulated as concentrates (e.g., pre-mix composition (formulation)), the end user will normally employ dilute formulations (e.g., tank mix composition). Preferred seed treatment pre-mix formulations are aqueous suspension concentrates. The formulation can be applied to the seeds using conventional treating techniques and machines, such as fluidized bed techniques, the roller mill method, roto static seed treaters, and drum coaters. Other methods, such as spouted beds may also be useful. The seeds may be pre sized before coating. After coating, the seeds are typically dried and then transferred to a sizing machine for sizing. Such procedures are known in the art. The compounds of the present invention are particularly suited for use in soil and seed treatment applications.

The plant propagation material protecting composition or mixture may also comprise at least one polymer from water-soluble and water-dispersible film-forming polymers that improve the adherence of the active ingredients to the treated plant propagation material, which polymer generally has an average molecular weight of at least 10,000 to about 100,000. In an embodiment, the present invention provides a method of controlling or preventing infestation of useful plants by phytopathogenic nematodes in agricultural crops and/or horticultural crops, wherein the compound of formula (I) or salts, stereoisomers, polymorphs, or N-oxides thereof or composition or combination thereof, is applied to the plants, to parts thereof or a locus thereof. In another embodiment, the present invention provides a method of controlling or preventing an infestation of useful plants by phytopathogenic nematodes in agricultural crops and/or horticultural crops, wherein the compound of formula (I) or salts, stereoisomers, polymorphs or N-oxides thereof or composition or combination thereof is applied to the seeds of plants. In yet another embodiment, the present invention provides a method of controlling or preventing the infection with phytopathogenic nematodes in agricultural crops and/or horticultural crops using the compound of formula (I) or salts, stereoisomers, polymorphs or N-oxides thereof or composition or combination thereof comprising a step of applying an effective dosage of the compound or the composition or the combination, in amounts ranging from 1 g to 5 kg per hectare of agricultural crops and/or horticultural crops. Examples of application methods for the compounds of the invention and compositions thereof, that is the method of controlling pests in the agriculture, are spraying, atomizing, dusting, brushing on, dressing, scattering or pouring which are to be selected to suit the intended aims of the prevailing circumstances. One method of application in agriculture is the application to the foliage of the plants (foliar application), it being possible to select frequency and rate of application to match the danger of infestation with the pest in question. Alternatively, the active ingredient can reach the plants via the root system (systemic action), by applying the compound to the locus of the plants, for example by an application of a liquid composition of the compound into the soil (by drenching), or by applying a solid form of the compound in the form of granules to the soil (soil application). In the case of paddy rice plants, such granules can be metered into the flooded paddy-field. The application of the compounds of the present invention to the soil is a preferred application method. Typical rates of application per hectare are generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 10 to 600 g/ha, such as 50 to 300 g/ha. In one embodiment, the present invention provides a seed comprising the compound of formula (I) or salts, stereoisomers, polymorphs or N-oxides thereof or composition or combination thereof, wherein the amount of the compound of the formula (I) is ranging from 0.1 g to 10 kg per 100 kg of seed. The compounds of the invention and compositions thereof are also suitable for the protection of plant propagation material, for example seeds, such as fruit, tubers or kernels, or nursery plants, against pests of the abovementioned type. The propagation material can be treated with the compound prior to planting, for example seed can be treated prior to sowing. Alternatively, the compound can be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by applying a layer of a solid composition. It is also possible to apply the compositions when the propagation material is planted to the site of application, for example into the seed furrow during drilling. These treatment methods for plant propagation material and the plant propagation material thus treated are further subjects of the invention. Typical treatment rates would depend on the plant and pest to be controlled and are generally between 1 to 200 g per 100 kg of seeds, preferably between 5 to 150 g per 100 kg of seeds, such as between 10 to 100 g per 100 kg of seeds.

The present invention also comprises seeds coated or treated with or containing a compound of formula (I). The term “coated or treated with and/or containing” generally signifies that the active ingredient is for the most part on the surface of the seed at the time of application, although a greater or lesser part of the ingredient may penetrate into the seed material, depending on the method of application. When the said seed product is (re)planted, it may absorb the active ingredient. In an embodiment, the present invention makes available a plant propagation material adhered thereto with a compound of formula (I) or a composition comprising a plant propagation material treated with a compound of formula (I). Seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking and seed pelleting. The seed treatment application of the compound of formula (I), which is a preferred application method, can be carried out by any known methods, such as spraying or by dusting the seeds before sowing or during the sowing/planting of the seeds. Suitable target plants are, in particular, cereals, such as wheat, barley, rye, oats, rice, maize or sorghum; beet, such as sugar or fodder beet; fruit, for example banana, pomaceous fruit, stone fruit or soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, for example strawberries, raspberries or blackberries; leguminous plants, such as beans, lentils, peas or soya; oil plants, such as oilseed rape, mustard, poppies, olives, sunflowers, coconut, castor, cocoa or ground nuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruit or tangerines; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes or bell peppers; Lauraceae, such as avocado, Cinnamonium or camphor; and also tobacco, nuts, coffee, eggplants, sugarcane, tea, pepper, grapevines, hops, the plantain family, latex plants and ornamentals (such as flowers, and lawn grass or turf). In an embodiment, the plant is selected from cereals, corn, soybean, rice, sugarcane, vegetables, and oil plants. The term “plant” is to be understood as including also plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesizing one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus and also plants which have been selected or hybridized to preserve and/or attain a desired trait, such as insect, and /or nematode resistance. Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins from Bacillus cereus or Bacillus popilliae; or insecticidal proteins from Bacillus thuringiensis, such as 8-endotoxins, e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vip1, Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins, such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl- transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases. In the context of the present invention there are to be understood by 8-endotoxins, for example Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), for example Vip1, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncated toxins and modified toxins. Hybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). Truncated toxins, for example a truncated Cry1Ab, are known. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of Cry3A055, a cathepsin-G- recognition sequence is inserted into a Cry3A toxin (see WO 03/018810). Examples of such toxins or transgenic plants capable of synthesizing such toxins are disclosed, for example, in EP-A-0374753, WO 93/07278, WO 95/34656, EP-A-0427529, EP-A-451 878 and WO 03/052073. The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. Cryl-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP-A-0367474, EP-A-0401979 and WO 90/13651. The toxin contained in the transgenic plants imparts to the plant’s tolerance to harmful insects. Such insects can occur in any taxonomic group of insects but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and butterflies (Lepidoptera). Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available. Examples of such plants are: YieldGard® (maize variety that expresses a Cry1Ab toxin); YieldGard Rootworm® (maize variety that expresses a Cry3Bb1 toxin); YieldGard Plus® (maize variety that expresses a Cry1Ab and a Cry3Bb1 toxin); Starlink® (maize variety that expresses a Cry9C toxin); HerculexI® (maize variety that expresses a Cry1Fa2 toxin and the enzyme phosphinothricine N-acetyltransferase(PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry1Ac toxin); Bollgard I® (cotton variety that expresses a Cry1Ac toxin); Bollgard II® (cotton variety that expresses a Cry1Ac and a Cry2Ab toxin); VipCot® (cotton variety that expresses a Vip3A and a Cry1Ab toxin); Newleaf® (potato variety that expresses a Cry3A toxin); NatureGard®, 25Agrisure® GT Advantage (GA21 glyphosate-tolerant trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait) and Protecta®.

Step-6: 1-(2,4-dichlorophenyl)-N-((2,5-dimethylphenyl)sulfonyl)-5-me thyl-1H-1,2,3- triazole-4-carboxamide 1-(2,4-dichlorophenyl)-N-((2,5-dimethylphenyl)sulfonyl)-5-me thyl-1H-1,2,3-triazole-4- carboxamide was synthesized by following the procedure as described in step-4 of example-2, using 1-(2,4-dichlorophenyl)-5-methyl-1H-1,2,3-triazole-4-carboxyl ic acid and 2,5- dimethylbenzenesulfonamide as starting materials. ¹ H-NMR (400 MHz, DMSO-d ₆ ) δ 12.94 (s, 1H), 8.05 (d, J = 1.8 Hz, 1H), 7.86 (d, J = 0.9 Hz, 1H), 7.78-7.72 (m, 2H), 7.39 (d, J = 7.6 Hz, 1H), 7.29 (d, J = 7.6 Hz, 1H), 2.59 (s, 3H), 2.36 (s, 3H), 2.25 (s, 3H); LCMS (M+1): 440.0. Table A: Representative compounds of the present disclosure were prepared according to the suitable methods as described in the respective schemes and examples. Table-A:

As described herein the compounds of formula (I) show high nematicidal activity which is exerted with respect to nematodes which attack important agricultural crops. The compounds of the present invention were assessed for their activity against one or more of the following nematodes. Biological examples Biological Test Examples for Plant parasitic nematodes Example 1: Meloidogyne incognita Test: The trial pots were filled with soil containing a mixture of sand:soil:cocopeat in a ratio of 1:1:1. To the soil of each pot 5mL of a nematode suspension (Meloidogyne incognita, mix of 5000 eggs & J2s) was added. One hour later the respective test compound at the stated concentration was applied to each pot. 10 days old cucumber seedlings were transplanted into the pots one day after the application. The cucumber plants were allowed to grow at a temperature of 27˚C under greenhouse conditions. The evaluation of the gall rating was recorded 30 days after the application. The plants were carefully uprooted and the roots were thoroughly washed. The gall rating was done on a 0-10 scale as described by Zeck (1971) and shown below: 0 = no galls 1 = very few small galls 2 = numerous small galls 3 = numerous small galls of which some are grown together 4 = numerous small and some big galls 5 = 25% of roots severely galled 6 = 50% of roots severely galled 7 = 75% of roots severely galled 8 = no healthy roots but plant is still green 9 = roots rotting and plant dying 10 = plant and roots dead Compounds 2, 7, 8, 17, 25, 33, 35, 52, 56, 57, 61, 76, 96, 97, 108, 132, 133, 134, 135, 140, 143, 168, 171, 209, 210, 217, 218, 227, 228, 229, 230, 231, 240, 241, 242, 245, 246, 250, 252, 253, 254, 259, 260, 261, 269, 271, 272, 278, 279, 280, 281, 311, 315, 316, 328, 335, 336, 337, 338, 339, 364, 370, 371, 378, 389, 390, 394, 395, 396, 410, 413, 415, 430, 432, 433, 441, 443, 445, 446, 458, 459, 460, 497, 499, 513, 516, 536, 538, 563, 586, 587, 588, 590, 596, 597, 598, 599, 610, 630, 631, 640, 657, 664, 665, 666, 667, 668, 669, 670, 671, 672, 673, 674, 675, 676, 683, 687, 689, 690, 691, 709, 736, 774 and 776 at 1000 ppm recorded less than 4 of the gall rating scale whereas there was extensive galling ( up to 8) in the untreated check.
