Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a novel indazole compound. The present invention further relates to an insecticidal, miticidal, and fungicidal composition for use in agriculture and horticulture which comprises the indazole compound as an active ingredient. Related Art In the field of agriculture and horticulture, various fungicides and insecticides have been developed and practically used so far today for the purpose of controlling numbers of crop diseases and insect pests. However, agricultural and horticultural fungicides and insecticides ordinarily and widely used are not always satisfactory from viewpoints of fungicidal and insecticidal activities, fungicidal and insecticidal spectra, and safeties such as residual activities. In addition, they fail to meet requiements of reducing application frequencies and amounts. The appearance of phytopathogenic fungi and injurious insects which have aquired resistance to ordinary and widely used pesticides also raises a problem. For example, in the cultivations of vegetables, fruit trees, flowers, teas, barleys, wheats, rice and the like, numbers of pathogenic fungi and harmful insects appeared in various parts of the world, which have acquired resistance to various types of pesticides such as triazole type, imidazole type, pyrimidine type, benzimidazole type, dicarboxyimido type, phenylamido type, and organic phosphorus type. Thus, from year to year, it becomes more difficult to control these pathogenic fungi and harmful insects. There still remain several pesticides, e.g. dithiocarbamate type and phthalimide type pesticids, to which pathogenic fungi or harmful insects have not yet acquired resistance. However, these pesticides are not preferred in view of environmental pollutions due to their generally high application amounts and frequencies. Accordingly, developments of novel fungicides and insecticides are highly desired which have satisfactory controlling activities, at low application amounts, against various pathogenic fungi or harmful insects that have acquired resistances to ordinary and widely used agricultural and horticultural fungicides and insecticides, and also have reduced adverse effects on environment. Furthermore, as regards miticides, developments of miticides are desired which have high safety and excellent controlling effect against mites that have acquired resistances to conventional miticides. United States Patent No. 3,457,269; German Patents Nos. 2,015,568 and 2,135,398; United States Patents Nos. 3,647,819, 3,678,059, 3,681,382 and 3,711,610; Japanese Patent Unexamined Publication (KOKAI) No. 81858/1973; and Magy. Kem. Lapja., 30, 208, 1975 disclose indazole derivatives having pharmaceutical activities. However, all of these compounds are 1H-deviratives, and none of these documents teaches or suggests that the disclosed indazole derivatives have insecticidal, miticidal or fungicidal activities. Japanese Patent Unexamined Publication (KOKAI) No.207208/1989 discloses that esters of 1H-indazole-3-carboxylic acid and carboxamide derivatives (lower-alkylamines as amino moieties) have plant growth regulating activity. However, this publication neither teach nor suggest insecticidal, miticidal or fungicidal activity of the compounds. In addition, International Publication WO 94/5642 discloses 2H-indazole-3-carboxamides compounds and their insecticidal, miticidal or fungicidal activity. These compounds are characterized to have aralkylamines as amino moieties. More specifically, this documents merely exemplifies benzylamines and naphthalene methylamines which may be substituted. Accordingly, this publication neither teach nor suggest compounds having heteroaralkylamines as amino moieties as well as processes for preparation and insecticidal, miticidal and fungicidal activities of the compounds. SUMMARY OF THE INVENTION An object of the present invention is to provide chemical substances which have high controlling activities against various pathogenic fungi and harmful insects that are resistant to ordinary and widely used agricultural and horticultural fungicides, insecticides and miticides and thus are useful as active ingredients of agricultural and horticultural compositions as fungicides and insecticides. Another object of the present invention is to provide chemical substances useful as active ingredients of agricultural and horticultural compositions as fungicides and insecticides which have the above features and high safeties due to reduced problems of residual toxicities and environmental pollutions. Further object of the present invention from another aspect is to provide novel indazole derivatives having the aforementioned utilities which have 2H-indazole as acid moieties and pyridylmethylamines as amino moieties. The inventors of the present invention couducted various researches to achieve the foregoing objects, and as a result, they found that novel indazole compounds represented by the formula set out below have the aforementioned features. The present invention was achieved on the basis of the findings.

The compounds of the present invention have potent fungicidal activity against phytopathogenic fungi such as Piricularia (Blast causing fungi); Puccinia (Rust causing fungi); Phytophthora; Erysiphe (Downy mildew causing fungi), and thus are useful as active ingredients of agricultural and horticultural fungicides.

For example, where emulsifiable concentrates are used, neat stock concentrates can be prepared by mixing solvents, surfactants and the like to the aforementioned compounds as the active ingredients, and the resulting neat concentrates can be diluted with water to prescribed concentrations before use and then applied. Where wettable powder are used, neat stock compositions can be prepared as the mixture of the aforementioned compounds as the active ingredients, solid carriers, surfactant and the like, and the resulting stock compositions can be diluted to prescribed concentrations before use and then applied. Dusts may be prepared by mixing the above compounds as the active ingredients with solid carriers and the like, and the resulting mixture, per se, may be applied. Granules can be prepared by granulations of mixutures of the above compounds as active ingredients, solid carriers, surfactant and the like, and the resulting compositions, per se, may be applied. Methods for preparations of the compositions in the aforementioned forms are not limited to those set out above, and the processes may appropriately be chosen by ordinary artisens depending on, for example, the types of the active ingredients and the purposes of applications. Agricultural and horticultural fungicides, insecticides, and/or miticides of the present invention may optionally contain, in addition to the compounds of the present invention as the active ingredients, other active ingredients such as, for example, other fungicides, insecticides, miticides, herbicides, insect growth regulators, fertilizers, soil conditioners.

EXAMPLES The present invention will be further explained by examples. However, the scope of the present invention is not limited to the examples set out below. Example 1 Preparation of N-[(6-n-butyl-3-pyridyl)-methyl]-2-methyl-3-indazolecarboxamide 2-Methylindazole-3-carboxylic acid (3.2 g) and thionyl chloride (5.3 g) were heated under reflux for 1 hour. After thionyl chloride was evaporated under reduced pressure, the residue was dissolved in toluene (20 ml). This solution was added dropwise to a solution of 5-aminomethyl-2-n-butylpyridine (3.0 g) and triethylamine (1.9 g) in toluene (30 ml) at 0 to 10°C. After the dropwise addition, the mixture was stirred for 2 hours at room temperature, and then, poured into ice water and extracted with toluene. The toluene layer was successively washed with an aqueous solution of sodium carbonate, water, and saturated aqueous sodium chloride.
