[0336] Since the agricultural and horticultural insecticides containing the compounds represented by the general formula (1) of the present invention or their salts as active ingredients have a significant control effect on the pests that damage paddy field crops, dry field crops, fruit trees, vegetables, other crops, flowers, etc., the desired effect of the agricultural and horticultural insecticide of the present invention is achieved by treating the cultivation carriers such as seeds, paddy field water, stems and leaves, or soil of seedling facilities, paddy fields, dry fields, fruit trees, vegetables, other crops, flowers, etc., before the occurrence of pests or at the time when the occurrence of pests is confirmed according to the predicted period of occurrence of pests. Among them, the preferred mode of use is to treat the seedling soil of crops, flowers, etc., the soil of the planting hole during transplantation, the roots of plants, irrigation water, and cultivation water in hydroponic cultivation, and absorb the compounds of the present invention through the soil or without passing through the soil, thereby utilizing the so-called penetration transfer.

[0337] There are no particular limitations on the useful plants to which the agricultural and horticultural pesticide of the present invention can be applied, and examples thereof include: cereals (e.g., rice, barley, wheat, rye, oats, corn, etc.), legumes (soybeans, red beans, broad beans, peas, kidney beans, peanuts, etc.), fruit trees and fruits (apples, citrus fruits, pears, grapes, peaches, plums, cherries, walnuts, chestnuts, almonds, bananas, etc.), leafy and fruity vegetables (cabbage, tomatoes, spinach, broccoli, lettuce, onions, shallots (shallots, shallots), bell peppers, eggplants, strawberries, peppers, okra, leeks, etc.), root vegetables (carrots, potatoes, sweet potatoes, taro, radishes, turnips, lotus roots, burdocks, garlic, scallions, etc.), processed vegetables (e.g., spinach, broccoli, lettuce, onions, shallots, shallots, etc.), Crops for agricultural use (cotton, hemp, beetroot, hops, sugarcane, beet, olive, rubber, coffee, tobacco, tea, etc.), melons (pumpkin, cucumber, watermelon, mulberry, melon, etc.), forage grasses (duckgrass, sorghum, timothy, clover, alfalfa, etc.), zoysia grasses (Korean zoysia, Agrostis, etc.), ornamental crops such as spices (lavender, rosemary, thyme, parsley, pepper, ginger, etc.), flowers (chrysanthemum, rose, carnation, orchid, tulip, lily, etc.), garden trees (ginkgo, cherry, coral wood, etc.), forest trees (fir, spruce, pine, cypress, fir, Japanese cypress, eucalyptus, etc.), etc.

[0338] The "plants" also include plants that have been given resistance to herbicides through classical breeding methods or genetic recombination technology, and the herbicides include: HPPD inhibitors such as isoxathiapiprolin, ALS inhibitors such as imazethapyr and thifensulfuron-methyl, EPSP synthase inhibitors such as glyphosate, glutamine synthetase inhibitors such as glufosinate, acetyl-CoA carboxylase inhibitors such as sethoxydim, bromoxynil, dicamba, 2,4-D, etc.

[0339] As examples of "plants" that have been given resistance through classical breeding methods, rapeseed, wheat, sunflower, and rice that are resistant to imidazolinone ALS-inhibiting herbicides such as imazethapyr, and are already sold under the trade name of Clearfield (registered trademark), can be cited. Soybeans that are resistant to sulfonylurea ALS-inhibiting herbicides such as thifensulfuron-methyl can be cited, and are already sold under the trade name of STS soybeans. As examples of plants that have been given resistance to acetyl-CoA carboxylase inhibitors such as trion oximes and aryloxyphenoxypropionic acid herbicides through classical breeding methods, SR corn (Cone) can be cited.

[0340] In addition, plants imparted with resistance to acetyl-CoA carboxylase inhibitors are described in Proceedings of the National Academy of Sciences of the United States of America (Proc. Natl. Acad. Sci. USA) Vol. 87, pp. 7175-7179 (1990) and the like. In addition, mutant acetyl-CoA carboxylases resistant to acetyl-CoA carboxylase inhibitors have been reported in Weed Science, Vol. 53, pp. 728-746 (2005), etc. Such mutant acetyl-CoA carboxylase genes can be introduced into plants by gene recombination technology, or by introducing a mutation associated with imparting resistance into plant acetyl-CoA carboxylase, thereby obtaining plants resistant to acetyl-CoA carboxylase inhibitors. In addition, by introducing a nucleic acid introduced with a base substitution mutation into plant cells, such as the chimeraplasty technology (Gura T. 1999. Repairing the Genome's Spelling Mistakes. Science 285: 316-318.), thereby introducing an amino acid substitution mutation site-specifically into the acetyl-CoA carboxylase gene, ALS gene, etc. of the plant, plants resistant to acetyl-CoA carboxylase inhibitors, ALS inhibitors, etc. can be obtained. The agricultural and horticultural insecticide of the present invention can also be used for these plants.

[0341] In addition, examples of toxins expressed in genetically modified plants include insecticidal proteins derived from Bacillus cereus and Bacillus japonicus; δ-endotoxins such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, insecticidal proteins such as VIP1, VIP2, VIP3 or VIP3A derived from Bacillus thuringiensis; insecticidal proteins derived from nematodes; toxins produced by animals such as scorpion toxins, spider toxins, bee toxins or insect-specific neurotoxins; filamentous fungal toxins; plant lectins; lectins; protease inhibitors such as trypsin inhibitors, serine protease inhibitors, potato tuber storage proteins (Patatin), cysteine ​​protease inhibitors, and papain inhibitors; ricin, corn-RIP, ormosine, rufin, saporin, Bryonia dioica) and other ribosome inactivating proteins (RIP); steroid metabolic enzymes such as 3-hydroxysteroid oxidase, ecdysteroid-UDP-glucosyltransferase, cholesterol oxidase; ecdysone inhibitors; HMG-CoA reductase; ion channel inhibitors such as sodium channel and calcium channel inhibitors; juvenile hormone esterase; diuretic hormone receptor; stilbene synthase; bibenzyl synthase; chitinase; glucanase, etc.

[0342] In addition, as toxins expressed in such genetically modified plants, there are also mixed toxins, partially deleted toxins, and modified toxins of δ-endotoxin proteins such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1, Cry9C, Cry34Ab or Cry35Ab, insecticidal proteins such as VIP1, VIP2, VIP3 or VIP3A. Using recombinant technology, mixed toxins are produced by new combinations of different domains of these proteins. As partially deleted toxins, Cry1Ab is known to have a part of the amino acid sequence deleted. As modified toxins, one or more amino acids of the natural toxin are replaced.

[0343] Examples of these toxins and recombinant plants capable of synthesizing these toxins are described in EP-A-0374753, WO93 / 07278, WO95 / 34656, EP-A-0427529, EP-A-451878, WO03 / 052073 and the like.

[0344] The toxins contained in these recombinant plants confer resistance to beetle pests, hemiptera pests, diptera pests, lepidoptera pests, nematodes. The agronomic and horticultural pesticides of the present invention can be used in combination with these technologies or in a systemic manner.

[0345] In order to control various pests, the agricultural and horticultural pesticide of the present invention can be directly applied in an amount effective for controlling pests or nematodes, or appropriately diluted with water or the like, or used in a suspended form on plants predicted to have the pests and nematodes. For example, for pests and nematodes occurring in fruit trees, cereals, vegetables, etc., in addition to spreading on stems and leaves, the agricultural and horticultural pesticide of the present invention can be used by treating the soil, etc., such as soaking the seeds in the agent, applying a powder coat to the seeds, treating the seeds with calcium peroxide, mixing the soil in the whole layer, applying strips, mixing the bed soil, treating the seedlings in a tray, treating the planting holes, treating the root system, applying top fertilizer, treating the rice in a box, applying on the water surface, etc., so that the soil can be absorbed by the roots. In addition, the agricultural and horticultural pesticide of the present invention can be used by applying to the nutrient solution in nutrient solution (hydroponics) cultivation, fumigating or injecting into the trunk, etc.

[0346] In addition, the agronomic and horticultural pesticide of the present invention can be used directly or in a suspended form with water or the like in an amount effective for controlling pests at places where the pests are predicted to occur. For example, in addition to being spread on stored grain pests, house pests, sanitary pests, forest pests, etc., it can also be used as a coating, fumigation, bait, etc. on building materials.

[0347] As a method for treating seeds, for example, there can be mentioned: a method of impregnating seeds with a liquid or solid preparation in a diluted or undiluted liquid state to allow the agent to penetrate; a method of mixing a solid preparation or a liquid preparation with seeds and subjecting them to a powder coating treatment so as to adhere to the surface of the seeds; a method of coating the seeds by mixing with an adhesive carrier such as a resin or a polymer; a method of scattering near the seeds while planting, etc.

[0348] The "seeds" subjected to the seed treatment refer to plants in the early stage of cultivation used for plant propagation, and examples thereof include, in addition to seeds, bulbs, tubers, seed potatoes, plant buds, bulbils, bulbs, or plants for vegetative propagation for cutting cultivation.

[0349] When implementing the method of use of the present invention, the "soil" or "cultivation carrier" of the plant refers to a support for cultivating crops, especially a support for root growth. The material is not particularly limited, as long as it is a material on which plants can grow, and can be so-called soil, seedling mats, water, etc. Specific raw materials include, for example, sand, pumice, vermiculite, diatomaceous earth, agar, gel-like substances, polymer substances, rock wool, glass wool, wood chips, bark, etc.

[0350] The method of spreading the pesticide on the stems and leaves of crops or stored-grain pests, house pests, sanitary pests or forest pests includes: a method of spreading a liquid preparation such as an emulsion or suspension or a solid preparation such as a wettable powder or granular wettable powder by appropriately diluting it with water, a method of spreading a powder, or fumigation.

[0351] Examples of methods for applying to the soil include: a method in which a liquid preparation is diluted with water or undiluted and applied to the roots of a plant or a nursery bed for raising seedlings, a method in which granules are spread on the roots of a plant or a nursery bed for raising seedlings, a method in which powders, wettable powders, granular wettable powders, granules, etc. are spread before sowing or transplanting and mixed with the entire soil, a method in which powders, wettable powders, granular wettable powders, granules, etc. are spread on planting holes, strips, etc. before sowing or planting plants, and the like.

[0352] As a method of applying rice to a nursery box, the formulation may be different depending on the application period, such as application at the time of sowing, application during the greening period, application at the time of transplanting, and the formulation may be applied in the form of powder, granular wettable powder, granules, etc. It can be applied by mixing with the cultivation soil, and the cultivation soil and the powder, granular wettable powder or granules can be mixed, for example, by mixing with the bed soil, mixing with the covering soil, mixing with the entire cultivation soil, etc. The cultivation soil and various formulations can be simply applied by alternately forming layers.

[0353] As a method of applying to paddy fields, solid preparations such as jumbo, packaged preparations, granules, granular wettable powders, and liquid preparations such as flowable preparations and emulsions are usually spread on flooded paddy fields. In addition, appropriate preparations can be spread and injected into the soil directly or mixed with fertilizers during rice transplanting. In addition, it is possible to apply labor-savingly by using liquid medicines such as emulsions and flowable preparations at water inlets, irrigation devices, and other sources of water in paddy fields accompanied by water supply.

[0354] In dry field crops, the cultivation carrier near the seed or plant body can be treated during the period from sowing to seedling raising. In plants directly sown in dry fields, in addition to directly treating the seed, it is preferred to treat the root of the plant in cultivation. Granules can be used for spreading treatment or diluted with water or undiluted agents for irrigation treatment in liquid form. It is also a preferred treatment to mix the granules with the cultivation carrier before sowing and then sow.

[0355] As a treatment for the sowing and seedling raising period of the cultivated plants to be transplanted, in addition to directly treating the seeds, it is preferred to irrigate the nursery bed with a liquid agent or to spread the granules. In addition, treating the planting hole with the granules during field planting or mixing the granules with the cultivation carrier near the transplanting position is also a preferred treatment.
