Abstract: To provide a pesticidal composition which has a wide pesticidal spectrum, is highly active and capable of reducing the amount of the active ingredient to be applied and has a long-lasting effect. Also provided is a method for controlling pests. The pesticidal composition comprises, as active ingredients, (A) at least one organic phosphorus compound selected from the group consisting of fosthiazate, imicyafos and cadusafos, and (B) fluensulfone. The method for controlling pests, comprises applying respective effective amounts of the above (A) and (B).

Abstract: To provide a pesticidal composition having a broad pesticidal spectrum, having high activity and having a long lasting effect. A pesticidal composition comprising as active ingredients at least one organic phosphorus compound (A) selected from the group consisting of fosthiazate and imicyafos and at least one compound (B) selected from the group consisting of clothianidin, dinotefuran, thiamethoxam, tefluthrin, silafluofen, chlorfluazuron, flufenoxuron and teflubenzuron (excluding a combination of fosthiazate and tefluthrin).

Abstract: Novel imidazole compounds are disclosed, which are represented by the following general formula: ##STR1## wherein: R.sub.1 represents a cyano group or a --CSNHR.sub.5 group, wherein R.sub.5 represents a hydrogen atom, a C.sub.1-4 alkyl group, or a --COR.sub.6 group, wherein R.sub.6 represents a C.sub.1-4 alkyl group, a halogenated C.sub.1-4 alkyl group, or a phenyl group;R.sub.2 and R.sub.3 each represents a hydrogen atom; a halogen atom; a nitro group; a cyano group; a trimethylsilyl group; a C.sub.3-6 cycloalkyl group; a naphthyl group; a C.sub.1-12 alkyl group which is optionally substituted with one or more halogen atoms, hydroxyl groups, acetoxy groups, C.sub.1-4 alkoxy groups, halogenated C.sub.1-4 alkoxy groups, phenyl groups, halogenated phenyl groups, or C.sub.1-4 alkylated phenyl groups; a C.sub.2-10 alkenyl group which is optionally substituted with one or more halogen atoms; a C.sub.

Abstract: A biocidal composition containing, as active ingredients, at least one imidazole compound represented by formula (I): ##STR1## wherein R.sup.1 represents a phenyl group, a halogen-substituted phenyl group, an alkyl group, or a halogen-substituted alkyl group; and R.sup.2 represents a halogen atom, and at least one other specific compound. The combination of the compound represented by formula (I) and other specific compound can produce an unexpected effect in amount required and biocidal spectrum.
