Firstly, in the present invention, the term “unsubstituted” means only the core group. When the term “substituted” does not appear and only the name of the core group is recorded, the meaning “unsubstituted” is implied unless specifically stated otherwise.
On the other hand, the term “substituted” means that one of the hydrogen atoms of the core group has been substituted with a group having a structure either the same as, or different from, the core group. Accordingly, the “substituent” is another group that is bonded to the core group. There may be either one substituent, or two or more substituents. In the case of two or more substituents, the substituents may be the same or different.
There are no particular limitations on the “substituent”, provided it is chemically permissible and yields a compound having the effects of the present invention.

The sufonylaminobenzamide compound of the present invention has an excellent control effect on pests such as various agricultural pests, mites and nematodes that affect the growth of plants.
Further, because the sufonylaminobenzamide compound of the present invention causes no chemical damage to crops and exhibits low toxicity to fish and warm-blooded animals, it is a very safe compound. Accordingly, the compound is useful as an active constituent for insecticides, miticides and nematicides.
Moreover, in recent years, many insect pests such as Plutellidae, Delphacidae, Cicadellidae and Aphididae have developed resistance to various known chemical agents, causing problems of inadequate potency for these chemical agents, and there is much demand for a chemical agent that is also effective against these resistant strains. The sufonylaminobenzamide compound of the present invention exhibits an excellent control effect against insect pests, not only sensitive strains but also various resistant strains, and against mites of miticide-resistant strains.
Furthermore, the sufonylaminobenzamide compound of the present invention exhibits efficacy against all growth stages of the control target organisms, and for example exhibits a control effect on the eggs, nymphs, larvae, pupae and adults of mites, insects and nematodes.
The pest control agent, or insecticide, miticide or nematicide, of the present invention contains at least one compound selected from the sufonylaminobenzamide compounds of the present invention as an active constituent. There are no particular limitations on the amount of the sufonylaminobenzamide compound of the present invention contained within the pest control agent, insecticide, miticide or nematicide of the present invention, provided a pest control effect is exhibited.
The pest control agent, or insecticide, miticide or nematicide, of the present invention is preferably used on plants such as grains; vegetables; root vegetables; tubers; flowers and ornamental plants; fruit trees; trees such as foliage plants, tea plants, coffee plants, and cacao plants; pasture grasses; lawn grasses; and cotton plants.
During application to the plant, the pest control agent, insecticide, miticide or nematicide of the present invention may be applied to any portion of the plant, including the leaves, stems, stalks, flowers, buds, fruit, seeds, sprouts, roots, tubers, tuberous roots, shoots or cuttings.
Furthermore, the pest control agent, or insecticide, miticide or nematicide, of the present invention is not particularly limited in terms of the types of plants on which it can be applied. Examples of the types of plants include original species, variants, improved varieties, cultivars, mutants, hybrids, and genetically modified species (GMO).
