Application can be carried out before and after plant, plant propagation material such as seed, soil, surface, material or space are infested by insects.

[0080] In addition, invertebrate pests can be controlled by contacting a pesticidally effective amount of a compound of the invention with the target pest, its food supply, habitat, breeding ground, or its locus. Thus, application can be made before or after the locus, growing crop, or harvested crop is infested by the pest.

[0081] The compounds of the invention may also be applied preventatively to locations where pests are expected to appear.

[0082] The compounds of the present invention can also be used to protect growing plants from attack or infestation by pests by contacting the plants with a pesticidally effective amount of a compound of the present invention. Thus, "contacting" includes direct contact (applying the compound / composition directly to the pest and / or plant - typically to plant leaves, stems or roots) and indirect contact (applying the compound / composition to the locus of the pest and / or plant).

[0083] "Locus" means a habitat, breeding ground, plant, seed, soil, area, material or environment in which a pest or parasite is or may be growing.

[0084] Generally speaking, an "insecticidally effective amount" refers to the amount of active ingredient required to achieve an observable effect on growth, including necrosis, mortality, retardation, prevention, and removal, destruction, or reduction in the presence and activity of the target organism. The insecticidally effective amount may vary for the various compounds / compositions used in the present invention. The insecticidally effective amount of a composition may also vary depending on prevailing conditions such as the desired insecticidal effect and duration, weather, target species, location, mode of application, and the like.

[0085] The compounds of the invention are effective by contact (via soil, glass, walls, bed netting, carpeting, plant parts or animal parts) and ingestion (baits or plant parts).

[0086] The compounds of the present invention can also be applied against non-crop insect pests such as ants, termites, wasps, flies, mosquitoes, crickets or cockroaches. For use against such non-crop pests, the compounds of the present invention are preferably used in bait compositions.

[0087] Bait can be liquid, solid or semi-solid formulations (e.g. gels). Solid baits can be made into various shapes and forms suitable for the respective application, such as granules, blocks, rods, sheets. Liquid baits can be filled into various devices to ensure proper application, such as open containers, spray devices, droplet supply sources or evaporation sources. Gels can be based on aqueous or oily substrates and can be formulated according to specific requirements based on viscosity, moisture retention or aging characteristics.

[0088] The bait used in the composition is a product that is sufficiently attractive to stimulate insects such as ants, termites, wasps, flies, mosquitoes, crickets, etc. or cockroaches to eat it. The attractiveness can be regulated by using feeding stimulants or sex pheromones. Feeding stimulants are, for example, not exhaustively selected from animal and / or plant proteins (meat-, fish- or blood meals, insect parts, egg yolks), fats and oils of animal and / or plant origin or mono-, oligo- or poly-organic sugars, in particular sucrose, lactose, fructose, dextrose, glucose, starch, pectin or even molasses or honey. Fresh or rotten parts of fruits, crops, plants, animals, insects or specific parts thereof can also be used as feeding stimulants. It is known that sex pheromones are more insect-specific. Special pheromones are described in the literature and are known to those skilled in the art.

[0089] Formulations of the compounds of the invention as aerosols (eg in spray cans), oil sprays or pump sprays are highly suitable for the non-professional user to control pests such as flies, fleas, ticks, mosquitoes or cockroaches. Aerosol formulations preferably consist of the following components: active compound; solvents such as lower alcohols (e.g. methanol, ethanol, propanol, butanol), ketones (e.g. acetone, methyl ethyl ketone), paraffins with a boiling range of about 50-250° C. (e.g. kerosene), dimethylformamide, N-methylpyrrolidone, dimethyl sulfoxide, aromatic hydrocarbons such as toluene, xylene, water; in addition, adjuvants, for example emulsifiers such as sorbitol monooleate, oleyl ethoxylates with 3-7 mol of ethylene oxide, fatty alcohol ethoxylates, aromatic oils such as essential oils, esters of medium fatty acids with lower alcohols, aromatic carbonyl compounds; if appropriate, stabilizers such as sodium benzoate, amphoteric surfactants, lower epoxides, triethyl orthoformate and, if necessary, propellants such as propane, butane, nitrogen, compressed air, dimethyl ether, carbon dioxide, nitrous oxide or mixtures of these gases.

[0090] Oil spray formulations differ from aerosol formulations in that no propellant is used.

[0091] The compounds of the present invention and their corresponding compositions can also be used in mosquito coils and fumigation sheets, cigarette boxes, vaporizer plates or long-lasting vaporizers, as well as moth-catching papers, moth-catching pads or other vaporizer systems that are not related to heat.

[0092] Methods of controlling infectious diseases transmitted by insects (e.g., malaria, dengue and yellow fever, lymphatic filariasis and leishmaniasis) using the compounds of the present invention and corresponding compositions also include treating surfaces of sheds and houses, aerial spraying and impregnating curtains, tents, clothing, bedding, tsetse fly nets, etc. Insecticidal compositions applied to fibers, fabrics, knits, nonwovens, netting materials or foils and tarpaulins preferably comprise a mixture comprising an insecticide, an optional repellent and at least one binder. Suitable repellents are, for example, N,N-diethyl-m-toluamide (DEET), N,N-diethylphenylacetamide (DEPA), 1-(3-cyclohexane-1-ylcarbonyl)-2-methylpiperidine, (2-hydroxymethylcyclohexyl)acetic acid lactone, 2-ethyl-1,3-hexanediol, dimethicone, methyl neodecanoamide (MNDA), pyrethroids not used for insect control such as {(+ / -)-3-allyl-2-methyl-4-oxocyclopent-2-(+)-enyl-(+)-trans-chrysanthemate (Esbiothrin), repellents derived from plant extracts or identical to plant extracts such as 1,8-terpenoids, eugenol, (+)-Eucamalol (1), (-)-1-epi-eucamalol, or from plants such as Eucalyptus maculata, Vitex rotundifolia, Cymbopogan Crude plant extracts of plants such as Cymbopogan martinii, Cymbopogan citratus (lemongrass), and Cymopogan nartdus (lemongrass). Suitable binders are, for example, selected from polymers and copolymers of vinyl esters of aliphatic acids such as vinyl acetate and vinyl esters of branched alkane carboxylates, acrylates and methacrylates of alcohols such as butyl acrylate, 2-ethylhexyl acrylate and methyl acrylate, monoethylenically and diethylenically unsaturated hydrocarbons such as styrene, and aliphatic dienes such as butadiene.

[0093] Impregnation of curtains and bedding is usually carried out by dipping the textile material into an emulsion or dispersion of the insecticide or spraying them onto the bedding.

[0094] The compounds of the present invention and compositions thereof can be used to protect wood materials such as trees, guardrails, sleepers, and buildings such as houses, outbuildings, factories, as well as building materials, furniture, leather, fibers, vinyl products, wires and cables, etc., to prevent ants and / or termites, and to prevent ants and termites from damaging crops or humans (e.g., when pests invade houses and public facilities). The compounds of the present invention are not only applied to the surrounding soil surface or the soil under the floor to protect wood materials, but can also be applied to the surfaces of piled products such as concrete under the floor, pavilion columns, beams, plywood, furniture, etc., wood products such as particleboard, half-board, etc., and vinyl products such as coated wires, vinyl sheets, thermal insulation materials such as styrene foam, etc. In the application of preventing ants from damaging crops or humans, the ant control agent of the present invention is applied to crops or surrounding soil, or directly applied to ants' nests, etc.

[0095] The compounds according to the invention are therefore suitable for treating plant propagation material, especially seeds, for protecting them from insect pests, especially soil insect pests, and for protecting the roots and shoots of the resulting plants from soil pests and foliar insects.

[0096] The compounds of the present invention are particularly useful for protecting seeds from soil pests and protecting the roots and shoots of the resulting plants from soil pests and foliar insects. Preferably, the roots and shoots of the resulting plants are protected. More preferably, the shoots of the resulting plants are protected from piercing-sucking insects, with protection from aphids being most preferred.

[0097] The present invention therefore comprises a method for protecting seeds from insects, in particular soil insects, and for protecting the roots and shoots of rice seedlings from insects, in particular soil and foliar insects, which method comprises contacting the seeds with a compound according to the invention, including a salt thereof, before sowing and / or after pre-germination. Particularly preferred is a method in which the roots and shoots of plants are protected, more preferably a method in which the shoots of plants are protected from piercing-sucking insects, and most preferably a method in which the shoots of plants are protected from aphids.

[0098] The term seed includes seeds and plant propagules of all kinds, including but not limited to true seeds, seed pieces, suckers, corms, bulbs, fruits, tubers, kernels, cuttings, cut shoots, etc., and in preferred embodiments refers to true seeds.

[0099] The term seed treatment includes all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking and seed pelleting.

[0100] The invention also encompasses seeds coated with or containing the active compound.

[0101] The term "coated with and / or containing" generally means that the active ingredient is predominantly on the surface of the propagation product at the time of application, but a greater or lesser portion of the ingredient may penetrate into the propagation product, depending on the method of application. When the propagation product is (re)planted, it may absorb the active ingredient.

[0102] Suitable seeds are seeds of cereals, root crops, oil crops, vegetables, spice crops, ornamentals, for example durum wheat and other wheats, barley, oats, rye, corn (fodder corn and sugar corn / sweet corn and fodder corn), soybeans, oilseed crops, crucifers, cotton, sunflower, banana, rice, oilseed rape, turnip rape, sugar beet, fodder beet, eggplant, potato, grass, lawn, turf, fodder grass, tomato, leek, pumpkin, cabbage, endive, pepper, cucumber, melon, Brassica, melon, beans, peas, garlic, onion, carrot, tuber plants such as potatoes, sugarcane, tobacco, grapes, petunia, geranium / geranium, pansy and impatiens.

[0103] Furthermore, the active compounds can be used for treating the seeds of plants which have been made tolerant to the action of herbicides or fungicides or insecticides as a result of breeding, including genetic engineering methods.

[0104] For example, the active compounds can be used to treat plants that are resistant to herbicides selected from the group consisting of sulfonylureas, imidazolinones, glufosinate-ammonium or glyphosate-isopropylammonium and similar active substances (see, for example, EP-A 242 236, EP-A 242 246, WO 92 / 00377, EP-A 257 993, US Pat. No. 5,013,659) or seeds of transgenic crops, such as cotton, which produce Bacillus thuringiensis toxins (Bt toxins) to render the plants resistant to certain pests (EP-A 142 924, EP-A 193 259).

[0105] Furthermore, the active compounds can also be used to treat the seeds of plants which have modified properties compared to existing plants, which may have been produced, for example, by conventional breeding methods and / or mutants or by recombinant procedures. For example, numerous cases of recombinantly modifying crops to modify the starch synthesized in plants have been described (e.g. WO 92 / 11376, WO 92 / 14827, WO 91 / 19806), or transgenic plants with a modified fatty acid composition (WO 91 / 13972).

[0106] Seed treatment applications of the active compounds are carried out by spraying or dusting the seeds before sowing of the plants and before emergence of the plants.

[0107] Conventional seed treatment formulations include, for example, flowable concentrates FS, solutions LS, dry treatment powders DS, water-dispersible powders WS for slurry treatment, water-soluble powders SS, emulsions ES and EC, and gel formulations GF. These formulations can be applied to the seeds diluted or undiluted. Application to the seeds is made before sowing, either directly on the seeds or after the seeds have been pre-germinated.

[0108] Seed treatment formulations may additionally comprise a binder and optionally a colorant.

[0109] Binders may be added to improve the adhesion of the active substance to the seed after treatment. Suitable binders are homopolymers and copolymers of alkylene oxides, such as ethylene oxide or propylene oxide, polyvinyl acetate, polyvinyl alcohol, polyvinyl pyrrolidone and copolymers thereof, ethylene-vinyl acetate copolymers, acrylic homopolymers and copolymers, polyvinylamine, polyvinylamide and polyethyleneimine, polysaccharides such as cellulose, tylose and starch, polyolefin homopolymers and copolymers, such as olefin / maleic anhydride copolymers, polyurethanes, polyesters, polystyrene homopolymers and copolymers.

[0110] Optionally, colorants may also be included in the formulation.

[0111] An example of a gelling agent is carrageenan

[0112] In principle, the method that can be used for treating seed is all suitable seed treatment techniques known in the art, especially seed dressing technology, such as seed coating (such as seed pelleting), seed dusting and seed imbibition (such as seed soaking).Herein, "seed treatment" refers to all methods of contacting seeds with the compounds of the present invention, and "seed dressing" refers to a seed treatment method in which a certain amount of the compounds of the present invention is provided to seeds, i.e., it produces seeds comprising the compounds of the present invention. In principle, seeds can be treated at any time during the sowing of seeds after the seeds are harvested. Seeds can be treated using (for example) a "sowing box" method just before planting seeds or during planting seeds. However, it is also possible to treat in the form of seed dressing several weeks or several months (for example, up to 12 months) before planting seeds, without observing a significant reduction in efficacy.

[0113] The treatment can conveniently be carried out on unplanted seeds. The term "unplanted seeds" as used herein is intended to include seeds at any stage from harvesting the seeds to sowing the seeds in the ground for plant germination and growth.

[0114] In particular, the treatment involves mixing the seeds with the desired amount of the seed treatment formulation, either untreated or previously diluted with water, in a suitable apparatus (e.g. a mixing apparatus for mixing solids or solid / liquid mixing pairs) until the composition is evenly distributed over the seeds. If appropriate, this is followed by a drying step. DETAILED DESCRIPTION
