DISCLOSURE OF THE INVENTION
OBJECT TO BE ACCOMPLISHED BY THE INVENTION
In recent years, in agricultural and horticultural fields, due to use of pesticides such as insecticides, miticides and nematicides for many years, pests have acquired resistance and are hardly controlled. Further, use of highly noxious pesticides has been a problem.
With respect to application of a pesticide, in a case where a pesticide is directly sprayed to a plant for example, no sufficient pesticidal effect is obtained in some cases due to non-uniform spraying, transpiration, decomposition by light, outflow of chemicals by rain, etc. On the other hand, when a pesticide is applied to the soil and is absorbed from e.g. the root of a plant, the chemical will spread all over the plant body, and a stable effect will be obtained. Further, pesticides applicable to soil treatment are advantageous to those who are engaged in agriculture from such a viewpoint that exposure to the chemical by spraying is small, and the method for applying the chemical is simple, thus leading to power saving.
However, at present, very few pesticides such as insecticides, miticides and nematicides, which can be utilized for soil treatment and which are practical, have been known.
It is an object of the present invention to solve the above problems of conventional pesticides such as insecticides, miticides and nematicides, and to provide pesticides such as insecticides, miticides and nematicides, which are excellent in the safety, pesticidal effects, residual effectiveness, etc., which have infiltration, and which can be applied by soil treatment.
MEANS TO ACCOMPLISH THE OBJECT
To develop pesticides having the above-described preferred characteristics, the present inventors have prepared various 3-alkoxy-1-phenyl-pyrazole derivatives, and conducted extensive studies on their physiological activities. As a result, they have found that 3-alkoxy-1-phenyl-pyrazole derivatives (hereinafter sometimes referred to as the compounds of the present invention) represented by the following formula [I] have effects against various pests in agricultural and horticultural fields, and pests which have acquired resistance. They have found that the compounds exhibit very high effects especially against mites represented by two-spotted spider mite, Kanzawa spider mite and citrus red mite, pest hemipterans represented by brown rice planthopper, green rice leafhopper and cotton aphid, pest coleoptera represented by rice water weevil, rice leaf beetle and chafers, nematodes represented by southern root-knot nematode, and pest lepidopterans represented by diamondbackmoth, beat armyworm and cotton bollworm, have high activity even by soil treatment with which safe and labor-saving application becomes possible, and exhibit fungicidal effects against rice blast disease. The present invention has been accomplished on the basis of these discoveries.
The present invention provides the following (1) to (10).

TEST EXAMPLE 6: Miticidal test on two-spotted spider mites
A wettable powder prepared in accordance with Formulation Example 2 was diluted with water to a concentration of an active ingredient of 500 ppm. Soybean seedlings which had been inoculated with imago two-spotted spider mites were dipped in the solution and dried in air. The treated soybean seedlings were placed in a thermostatic chamber at 25°C for 13 days, and the number of live mites were assessed for calculation of the protective value by Equation 1. The test was carried out by one series system.

A compound to be tested was dissolved in N,N-dimethylformamide containing 1 mass% of tween 20, and this solution was diluted with distilled water to a concentration of an active ingredient of 20 ppm. 0.5 mL ofthe solution was mixed with 0.5 mL of a suspension containing about 30 second-instar larvaes of southern root-knot nematodes, and the mixture was placed in a thermostatic chamber at 25°C for 5 days. The number of dead nematodes and the number of live nematodes were assessed by a microscope for calculation of the mortality by Equation 3. The test was carried out by two series system.
Compounds which exhibit a mortality of 90% or higher in this test are indicated by compound numbers.
