Indazole compounds and the use thereof

An agricultural and horticultural pesticide which comprises an effective amount of an indazole compound represented by the formula ##STR14## wherein R.sup.1 represents a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 alkoxy group, or a halogen atom;

• R.sup.2 represents a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.2 -C.sub.5 alkanoyl group, methoxymethyl group, or 2-methoxy ethyl group;
• R.sup.3 represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group;
• R.sub.4 represents a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 alkoxy group, a halogen atom, a C.sub.1 -C.sub.4 haloalkoxy group, a 5-membered to 7-membered cycloalkoxy group which may be substituted, a C.sub.1 -C.sub.4 alkylthio group, a phenylamino group which may be substituted, an N-(C.sub.1 -C.sub.4 alkyl)-phenylamino group, pyrrolyl group, imidazolyl group, pyrrolidino group, a piperidino group which may be substituted, or a phenoxy group which may be substituted, and where a functional group selected from the group consisting of said cycloalkoxy, phenylamino, piperidino, and phenoxy groups has two or more substituents on its nucleus, any two adjacent substituents among said substituents may form a ring structure together with two atoms on the nucleus to which the adjacent substituents bind, and said ring structure may further has one or more substitutents on the ring, and an agrochemical adjuvant therefor.
