[0028] In the definitions of the compounds represented by the above general formula and all the following structural formulas, the technical terms used, whether used alone or in a compound word, represent the following substituents: An alkyl group having more than two carbon atoms can be straight-chain or branched-chain. For example, in the compound word "-alkylene-(CO)OR3", the alkylene can be -CH2-, -CH2CH2-, -CH(CH3)-, -C(CH3)2-, etc. The alkyl group is, for example, C1 alkyl - methyl; C2 alkyl - ethyl; C3 alkyl - propyl such as n-propyl or isopropyl; C4 alkyl - butyl such as n-butyl, isobutyl, tert-butyl or 2-butyl; C5 alkyl - pentyl such as n-pentyl; C6 alkyl - hexyl such as n-hexyl, isohexyl and 1,3-dimethylbutyl. Similarly, the alkenyl group is, for example, vinyl, allyl, 1-methylprop-2-en-1-yl, 2-methylprop-2-en-1-yl, but-2-en-1-yl, but-3-en-1-yl, 1-methylbut-3-en-1-yl and 1-methylbut-2-en-1-yl.

[0032] If a group is substituted by a group, this shall be understood to mean that the group is substituted by one or more identical or different groups selected from those mentioned. Additionally, the identical or different substitution characters contained in the identical or different substituents are each independently selected and may be the same or different. This also applies to ring systems formed by different atoms and units. At the same time, the scope of the claims will exclude those compounds that are known to those skilled in the art to be chemically unstable under standard conditions.
[0033] Additionally, unless otherwise specified, "substituted by at least one group" as used in the present invention means substituted by, for example, 1, 2, 3, 4, or 5 groups; for a group without a specific connection position indicated (including a heterocyclic group, an aryl group, etc.), it can be connected at any position, including positions connected to C or N; if it is substituted, the substituent can also be substituted at any position as long as it conforms to the chemical bond connection rules. For example, a heteroaryl group substituted by 1 methyl group can represent etc.

The term "wood" means all types of wood species, and all types of wood intended for construction work, such as solid wood, high-density wood, laminated wood and plywood. The method according to the invention for treating wood mainly comprises contacting one or more compounds or compositions according to the invention; this includes, for example, direct application, spraying, soaking, injection or any other suitable means.
[0085] When used alone, the compounds of the present invention can effectively control nematodes, insects, acarine pests and / or fungal pathogens of agronomic plants that are growing or have been harvested. They can also be used in combination with other biocides used in agriculture, for example, one or more nematicides, insecticides, acaricides, fungicides, bactericides, plant activators, molluscicides and pheromones (chemical or biological). Mixing the compounds or their compositions of the present invention in the form of a biocide with other biocides often results in a broader biocidal spectrum. For example, these compounds of the present invention having the formula I can be effectively combined or used in combination with the following compounds, which are pyrethroids, neonicotinoids, macrolides, diamides, phosphates, carbamates, cyclodienes, formamidines, phenol tin compounds, chlorinated hydrocarbons, benzoylphenylureas, pyrroles and the like.
[0086] By adding, for example, one or more insecticidal, acaricidal, nematicidal and / or fungicidal active agents, the activity of these compositions according to the present invention can be significantly broadened and is suitable for the prevailing environment. The combination of the compounds having the formula I with other insecticidal, acaricidal, nematicidal and / or fungicidal active agents can also have further, unexpected advantages. For example, better tolerance of the plants to them, reduced phytotoxicity, and pests or fungi can be controlled at their different developmental stages or have better behavior during their production (for example, during grinding or mixing processes, during their storage or during their use).

[0091] In general, the mass ratio between two components in any combination of the present invention is independently from 100:1 to 1:100, preferably from 75:1 to 1:75, more preferably from 50:1 to 1:50, especially from 25:1 to 1:25, advantageously from 10:1 to 1:10, such as from 5:1 to 1:5, for example from 1:3 to 3:1. These mixing ratios are understood to include, on the one hand, by mass, and on the other hand, the molar ratio.
[0092] Examples of methods of applying the compounds and their compositions of the present invention, i.e., methods for controlling pests / fungi in agriculture, such as spraying, atomizing, dusting, brushing, seed dressing, broadcasting or watering - they are selected to be suitable for the intended purpose of the environment at that time.
[0093] A preferred method of application in agriculture is application to the leaves of these plants (foliar application), and it is possible to select the frequency and rate of application to conform to the infestation risk of the pests / fungi under discussion. Alternatively, the active ingredient can reach the plants via the root system (systemic action), which is achieved by applying the compound to the sites of these plants, for example, by applying a liquid composition of the compound to the soil (by soaking) or by applying the compound in solid form in the form of granules to the soil (soil application). In the case of rice plants, such granules can be metered into flooded paddy fields.
[0094] The application rate per hectare is generally from 1 g to 2000 g of active ingredient per hectare, especially from 10 g / ha to 1000 g / ha, preferably from 10 g / ha to 600 g / ha, such as from 50 g / ha to 300 g / ha.
[0095] These compounds and their compositions of the present invention are also suitable for protecting plant propagation materials (such as seeds, fruits, tubers or grains, or nursery plants) against pests of the above types. The propagation materials can be treated with the compound before planting, for example, seeds can be treated before sowing. Alternatively, the compound can be applied to the seed grains (coating), which is achieved by dipping the grains into a liquid composition or by applying a layer of a solid composition. When the propagation materials are planted at the application site, it is also possible, for example, to apply these compositions into the seed furrows during drilling. These methods of treating plant propagation materials and thus treated plant propagation materials are additional subjects of the present invention. Typically, the treatment rate will depend on the plants to be controlled and the pests / fungi, usually between 1 g and 200 g per 100 kg of seeds, preferably between 5 g and 150 g per 100 kg of seeds, such as between 10 g and 100 g per 100 kg of seeds.
[0096] The term "seed" includes all kinds of seeds and plant propagules, including but not limited to true seeds, seed pieces, suckers, grains, corms, fruits, tubers, cereals, rhizomes, cuttings, cut shoots and the like and in a preferred embodiment refers to true seeds.
[0097] The invention also encompasses seeds coated or treated with or containing a compound of formula I. The terms "coated with / treated with and / or containing" generally mean that in most cases when applied the active ingredient is on the surface of the seed, although parts of more or less of the ingredient may penetrate into the seed material, depending on the method of application. When the said seed product is (re)planted, it can absorb the active ingredient. In one embodiment, the invention makes available a plant propagation material to which a compound of formula I is adhered. In addition, a composition comprising a plant propagation material treated with a compound of formula I is thereby available.
[0098] Seed treatment includes all suitable seed treatment techniques known in the art, such as, seed dressing, seed coating, seed dusting, seed soaking and seed granulation. Application of the compound of formula I for seed treatment can be effected by any known method, such as spraying or by dusting before sowing or during sowing / planting of these seeds.
[0099] Suitable target plants are in particular cereals, such as wheat, barley, rye, oats, rice, maize or sorghum; sugar beet, such as sugar or fodder beet; fruits, such as pomaceous fruits, stone fruits or drupes, such as apple, pear, plum, peach, almond, cherry or berries, such as strawberry, raspberry or blackberry; leguminous plants, such as beans, lentils, peas or soya; oil plants, such as rape, mustard, poppy, olive, sunflower, coconut, castor-oil plant, cocoa or groundnut; cucurbitaceous plants, such as pumpkin, cucumber or melon; fibre plants, such as cotton, flax, hemp or jute; citrus fruits, such as orange, lemon, grapefruit or tangerine; vegetables, such as spinach, lettuce, asparagus, cabbage, carrot, onion, tomato, potato or sweet pepper; lauraceous plants, such as avocado, Cinnamonium or camphor; and also tobacco, nuts, coffee, aubergine, sugar cane, tea, pepper, grapevine, hops, plantain, rubber plants and ornamental plants (such as flowers and turf plants or sods).
[0100] In one embodiment, the plant is selected from cereals, maize, soybean, rice, sugar cane, vegetables and oil plants.
[0101] The term "plant" is to be understood as also including plants transformed by means of recombinant DNA technology which are capable of synthesizing one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, in particular those of the genus Bacillus.
[0102] Transgenic plants containing one or more genes encoding insecticide resistance and expressing one or more toxins are known and some of them are commercially available.
[0103] Generally, the compounds of the present invention are used in the form of a composition (e.g., formulation) comprising a carrier. The compounds and compositions of the present invention can be used in different forms, e.g., aerosol spray, capsule suspension, cold fogging concentrate, dustable powder, emulsifiable concentrate, oil-in-water emulsion, water-in-oil emulsion, capsule granule, fine granule, flowable concentrate for seed treatment, gas (under pressure), gas generating product, granule, hot fogging concentrate, large granule, microgranule, oil-dispersible powder, oil-miscible flowable concentrate, oil-miscible liquid, paste, plant rod, powder for dry seed treatment, seed coated with a biocide, soluble concentrate, soluble powder, solution for seed treatment, suspension concentrate (flowable concentrate), ultra-low volume (ULV) liquid, ultra-low volume suspension (ULV), water-dispersible granule or tablet, water-dispersible powder for slurry treatment, water-soluble granule or tablet, water-soluble powder for seed treatment, and wettable powder.
[0104] A formulation typically comprises a liquid or solid carrier and optionally one or more conventional formulating aids which may be solid or liquid, e.g., non-epoxidized or epoxidized vegetable oils (e.g., epoxidized coconut oil, rapeseed oil or soybean oil), defoamers such as silicone oil, preservatives, clays, inorganic compounds, viscosity regulators, surfactants, binders and / or tackifiers. The composition may further comprise a fertilizer, micronutrient donor or other product affecting plant growth and comprises a combination comprising a compound of the present invention and one or more other bioactive agents such as bactericides, fungicides, nematicides, plant activators, acaricides and insecticides.
[0105] Accordingly, the present invention also makes available a composition comprising a compound of the present invention and an agriculturally economical carrier and optionally one or more conventional formulating aids.
[0106] These compositions are prepared by methods known per se, in the absence of auxiliaries, for example by grinding, sieving and / or extruding the solid compounds of the invention, and in the presence of at least one auxiliary, for example by intimately mixing and / or grinding the compounds of the invention with one or more auxiliaries. In the case of the solid compounds of the invention, the grinding / comminution of the compounds is to ensure a specific particle size. The methods for preparing these compositions and the use of the compounds of the invention for preparing these compositions are also a subject of the invention.
[0107] Examples of compositions for use in agriculture are emulsifiable concentrates, suspension concentrates, microemulsions, oil-dispersible powders, directly sprayable or dilutable solutions, coatable pastes, diluted emulsions, soluble powders, dispersible powders, wettable powders, dusts, granules or capsules in polymeric substances, these compositions comprising at least one compound according to the invention and the type of composition being chosen to suit the intended purpose and the prevailing circumstances.
[0108] Examples of suitable liquid carriers are: unhydrogenated or partially hydrogenated aromatic hydrocarbons, preferably the C8 to C 12 alkylbenzene moiety, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffin or cyclohexane, alcohols such as ethanol, propanol or butanol, ethylene glycol and their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene glycol or ethylene glycol monomethyl ether or hexylene glycol monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents, such as N-methylpyrrolidin-2-one, dimethyl sulfoxide or N,N-dimethylformamide, water, unepoxidized or epoxidized vegetable oils, such as unepoxidized or epoxidized rapeseed oil, castor oil, coconut oil or soybean oil and silicone oils.
[0109] Examples of solid carriers for, for example, dusts and dispersible powders are generally ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. It is also possible to add highly disperse silica or highly disperse absorbent polymers to improve the physical properties. Suitable particulate adsorptive carriers for granules are of the porous type, such as pumice, brick grit, sepiolite or bentonite, and suitable non-adsorptive carrier materials are calcite or sand. In addition, granulated materials of a large number of inorganic or organic natural substances can be used, especially dolomite or comminuted plant residues.
[0110] Depending on the type of active ingredient to be formulated, suitable surface-active compounds are nonionic, cationic and / or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties. The surfactants mentioned below are only to be regarded as examples; a large number of other surfactants which are conventionally used in the field of formulations and are suitable according to the invention are described in the relevant literature.
[0111] Suitable nonionic surfactants are, in particular, polyethylene glycol ether derivatives of aliphatic or cycloaliphatic alcohols, polyethylene glycol ether derivatives of saturated or unsaturated fatty acids or polyethylene glycol ether derivatives of alkylphenols, which polyethylene glycol ether derivatives may contain about 3 to about 30 ethylene glycol ether groups and about 8 to about 20 carbon atoms in the (cyclo)aliphatic hydrocarbon residue or about 6 to about 18 carbon atoms in the alkyl part of the alkylphenol. Also suitable are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopropylene glycol or alkyl polypropylene glycol (having 1 to about 10 carbon atoms in the alkyl chain and having about 20 to about 250 ethylene glycol ether groups and about 10 to about 100 propylene glycol ether groups). Generally, the above compounds contain 1 to about 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonoxynol, polyoxyethylene castor oil, polypropylene glycol / polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol or octylphenoxypolyethoxyethanol. Also suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.
[0112] These cationic surfactants are in particular usually quaternary ammonium salts having at least one alkyl residue (about 8 to about 22 C atoms) as a substituent and a (non-halogenated or halogenated) lower alkyl or hydroxyalkyl or benzyl residue as a further substituent. These salts are preferably in the form of halides, methyl sulfates or ethyl sulfates. Examples are stearyltrimethylammonium chloride and benzylbis(2-chloroethyl)ethylammonium bromide.
[0113] Examples of suitable anionic surfactants are water-soluble soaps or water-soluble synthetic surface-active compounds. Examples of suitable soaps are the alkali metal salts, alkaline earth metal salts or (unsubstituted or substituted) ammonium salts of fatty acids having from about 10 to about 22 C atoms, such as the sodium or potassium salts of oleic acid or stearic acid or natural fatty acid mixtures (obtainable, for example, from coconut oil or tall oil); mention must also be made of fatty acid methyl taurides. However, more commonly used are synthetic surfactants, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. Generally, these fatty sulfonates and fatty sulfates occur as alkali metal salts, alkaline earth metal salts or (substituted or unsubstituted) ammonium salts and they generally have an alkyl residue having from about 8 to about 22 C atoms, the alkyl also being understood to include the alkyl part of acyl residues; examples which may be mentioned are the sodium or calcium salts of lignosulfonic acid, the sodium or calcium salts of dodecyl sulfate or the sodium or calcium salts of mixtures of fatty alcohol sulfates prepared from natural fatty acids. This group also includes the sulfate salts and sulfonates of fatty alcohol / ethylene oxide adducts. These sulfonated benzimidazole derivatives preferably contain 2 sulfonyl groups and a fatty acid residue having from about 8 to about 22 C atoms. Examples of alkylaryl sulfonates are the sodium, calcium or triethanolammonium salts of decylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid or naphthalenesulfonic acid / formaldehyde condensates. In addition, suitable phosphates (esters), such as the phosphate salts of p-nonylphenol / (4-14) ethylene oxide adducts, or phospholipids, are also possible.
[0114] As a rule, these compositions comprise from 0.1% to 99% (in particular from 0.1% to 95%) of the compounds according to the invention and from 1% to 99.9% (in particular from 5% to 99.9%) of at least one solid or liquid carrier, and in principle it is possible for 0% to 25% (in particular 0.1% to 20%) of the composition to be a surfactant (in each case % denotes % by weight). However, for commercial products, concentrated compositions are generally preferred and the end user in principle uses diluted compositions having a significantly lower concentration of active ingredient.
[0115] Examples of formulation types suitable for tank mix compositions are solutions, dilute emulsions, suspensions or mixtures thereof, and dusts.
[0116] For the nature of these formulations, the methods according to the invention, such as leaf, drench, spray, atomize, dust, broadcast, coat or pour, can be selected according to the intended purpose and the prevailing environment.
[0117] Such tank mix formulations are generally prepared by diluting a pre-mix composition containing different pesticidal agents and optionally further adjuvants with a solvent (for example water).
[0118] Suitable carriers and adjuvants can be solid or liquid and are substances commonly used in formulation technology, such as natural or regenerated mineral substances, solvents, dispersants, wetting agents, thickeners, fillers, binders, or fertilizers.
[0119] Generally, tank-mix formulations for foliar or soil application comprise from 0.1% to 20%, especially from 0.1% to 15%, of the desired ingredient, and from 99.9% to 80%, especially from 99.9% to 85%, of solid or liquid auxiliaries (including, for example, a solvent such as water), and these auxiliaries can be a surfactant, the amount of which, based on the tank mixture formulation, is from 0 to 20%, especially from 0.1% to 15%.
[0120] Typically, premix formulations for foliar application comprise from 0.1% to 99.9%, especially from 1% to 95%, of the desired ingredient, and from 99.9% to 0.1%, especially from 99% to 5%, of solid or liquid adjuvants (including, for example, a solvent such as water), where these adjuvants can be a surfactant, the amount of which, based on the premix formulation, is from 0 to 50%, especially from 0.5% to 40%.
[0121] Generally, tank-mix formulations for seed treatment application comprise from 0.25% to 80%, especially from 1% to 75%, of the desired ingredient, and from 99.75% to 20%, especially from 99% to 25%, of solid or liquid auxiliaries (including, for example, a solvent such as water), where these auxiliaries can be a surfactant, the amount of which, based on the tank mixture formulation, is from 0 to 40%, especially from 0.5% to 30%.
[0122] Typically, premix formulations for seed treatment application comprise from 0.5% to 99.9%, especially from 1% to 95%, of the desired ingredient, and from 99.5% to 0.1%, especially from 99% to 5%, of solid or liquid adjuvants (including, for example, a solvent such as water), where these adjuvants can be a surfactant, the amount of which, based on the tank mixture formulation, is from 0 to 50%, especially from 0.5% to 40%.

For the cultured pathogenic bacteria, under aseptic conditions, use a sterile punch with a diameter of 3 mm to cut a mycelial disc from the edge of the colony, and inoculate the mycelial disc in the center of the medicament-containing plate with the mycelial side facing up, cover the lid, and culture in an incubator at 25 °C. After 4 days, investigate the growth of the pathogenic bacteria mycelia according to the growth of the bacteria in the blank control petri dish. Measure the colony diameter with a caliper, with the unit of millimeter (mm). Measure the diameter of each colony vertically once with the cross method, and take the average value. According to the investigation results, calculate the mycelial growth inhibition rate of each treatment concentration on the tested target bacteria according to formulas (1) and (2), with the unit of percentage (%).

Punch holes in the petri dish filled with mycelia to make 5-mm mycelial cakes, and inoculate the mycelial cakes on the host test materials. The inoculated test materials are transferred to an incubator or artificial climate chamber for culture without light.

[0218] Grade 3: The diseased area accounts for 6% - 10% of the whole leaf area;
[0219] Grade 5: The diseased area accounts for 11% - 25% of the whole leaf area;
[0220] Grade 7: The diseased area accounts for 26% - 50% of the whole leaf area;
[0221] Grade 9: The diseased area accounts for more than 50% of the whole leaf area.
[0222] Based on the survey data, the disease index and prevention and control effect of each treatment were calculated.
[0223] The disease index is calculated according to formula (1), and the result is rounded to two decimal places:
[0224] X={(∑(Ni xi)) / (N x 9)}x 100
[0225] In the formula: X is the disease index; Ni is the number of diseased leaves at each level; i is the relative level value; N is the total number of leaves surveyed.
