Abstract: 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. [in the above formula, R1 is, for example, a C1˜C6 alkyl group which is mono- or poly-substituted with halogen atom; R2 is, for example, a halogen atom or a C1˜C6 alkyl group; R3 is, for example, a hydrogen atom or a halogen atom; and R4 is, for example, a hydrogen atom or a C1˜C12 alkyl group.] The derivative or the salt has an excellent pest control effect.

Abstract: A plant disease control agent contains, as an active ingredient, at least one aminopyrimidine derivatives represented by General Formula [I]: wherein R is a C2-10 alkyl group; R1 and R2 are each independently a hydrogen atom or a substituent such as an optionally substituted C1-10 alkyl group; X is hydrogen or a substituent selected from a predefined substituent group; Y is a substituent selected from a predefined substituent group; and m is an integer from 0 to 3, and agriculturally acceptable salts thereof.
