In recent years, environmental pollution caused by various chemical substances has been regarded as a global problem, and there is a social demand to suppress the environmental release of chemical substances as much as possible. In the agricultural field, various methods for controlling pests other than chemicals such as creation of genetically modified crops, pest control by natural enemy organisms, and physical control are being studied.
However, pest control methods other than these chemical substances have many problems such as the ability to control only specific pests and unstable effects, and the necessity for control with chemical substances has not yet decreased.

  As a result of intensive studies aimed at reducing the amount of agricultural chemicals applied from the viewpoint of environmental pollution and the like, the present inventors have obtained a compound represented by the formula [I] and a neonicotinoid compound represented by the general formula [II]. It has been found that the mixture with the above exhibits a higher effect than expected when each of them is used alone, and therefore it is possible to reduce the application amount or the application frequency. In addition, pests can be controlled extremely effectively by applying these mixtures to places other than the sites where pests are directly infested, such as seeds, seed pods, or seedling soils for cultivating crops or soils in the main field. As a result of further finding and further intensive studies, the present invention has been completed.

The composition of the present invention has high insecticidal activity against many types of pests (including arthropods other than insect class) while having good safety for mammals and crops.
In general, when mixing two or more types of insecticidal compounds and aiming to enhance the efficacy or to expand the pests to be controlled, it is considered to use a mixture of each compound alone. In that case, the risk of phytotoxicity increases. In the pest control method of the present invention, since the compound represented by the formula [I] or a salt thereof itself has almost no risk of phytotoxicity, the neonicotinoid compound represented by the general formula [II] is used alone as a pest. The increase in the risk of phytotoxicity due to the mixed treatment of both compounds compared to the case of controlling is virtually negligible. Furthermore, the dose of one or both of the compounds represented by the formula [I] or a salt thereof and the neonicotinoid compound represented by the general formula [II] can be reduced from the amount used alone. As a result, the risk of chemical damage is further reduced.

For example, the composition of the present invention is sprayed onto paddy fields, fields, orchards, non-agricultural lands, houses, etc. by a method known per se, and controlled by contacting or ingesting the above-mentioned harmful insects (harmful insects, etc.). it can. As another embodiment, for example, by administering the composition of the present invention to the inside (in the body) or outside (the body surface) of the vertebrate, the arthropods and parasites parasitizing the vertebrate can be controlled. it can.

  As a method for concretely applying the composition of the present invention, it can be used in the same manner as the usual method for applying agricultural chemicals. Each single-component preparation can be mixed and used at the time of application. Application examples of such preparations include foliage spray, trunk spray, ULV spray, granule foliar spray, soil spray, soil irrigation, water surface application, soil admixture, floor soil admixture, nursery box treatment, nursery bed treatment, and stock treatment Grooving treatment, row treatment, side row application, trunk irrigation, trunk application, seed dressing, seed dressing, bulb dressing, seed soaking, seed soaking, bulb soaking, seed coating, seed coating, Examples thereof include, but are not limited to, bulb coating, poisonous bait, fertilizer admixture or watering for irrigation.

Or when seed pods or bulbs are planted (hereinafter referred to simply as sowing), seedling period, or seedling planting period, but they can be treated even during the growing period after seedling planting and sprayed with foliage May be a seedling growing period or a growing period in this farm.

  Seeding on seedling culture medium in which the composition of the present invention or the compound represented by the formula [I] or a salt thereof and the mixture of each single component preparation of the neonicotinoid compound represented by the general formula [II] is mixed. When pruning or temporarily planting using the soil, or when treating by soil solution irrigation or spraying granules during the seedling period including sowing, pests generated during the seedling period can also be controlled . The content ratio of the compound represented by the formula [I] or a salt thereof and the neonicotinoid compound represented by the general formula [II] in the mixture is the content ratio of each compound in the composition of the present invention described above. Is the same. The same applies to the following.

In the pest control method of the present invention, the treatment method at the time of planting seedlings includes the composition of the present invention, the compound represented by the formula [I] or a salt thereof and the neonicochi represented by the general formula [II] before planting. A mixture of each single-component preparation of the noid compound can be mixed with the entire field or mixed with straw soil, and the mixture may be sprayed with granules or irrigated with a solution. Further, after planting seedlings, the stock may be treated with the granules immediately, or the stock may be irrigated with the solution.
In the crop cultivated by sowing to the cultivation field, not only the treatment of seeds, but also the composition of the present invention or the compound represented by the formula [I] or a salt thereof and the general formula [II] before sowing A mixture of each single-component preparation of neonicotinoid compounds can be mixed with the entire field or mixed with soil in the straw.
