An alkyl phenyl sulfide derivative represented by the general formula [I] or an agriculturally acceptable salt thereof, and a pest control agent containing the derivative or the salt as an active ingredient. ##STR00001##
[in the above formula, R.sup.1 is, for example, a C.sub.1C.sub.6 alkyl group which is mono- or poly-substituted with halogen atom; R.sup.2 is, for example, a halogen atom or a C.sub.1C.sub.6 alkyl group; R.sup.3 is, for example, a hydrogen atom or a halogen atom; and R.sup.4 is, for example, a hydrogen atom or a C.sub.1C.sub.12 alkyl group.] The derivative or the salt has an excellent pest control effect.
