Diamine derivative, process for producing the same, and plant disease control agent containing the same as active ingredient

It is an object of the present invention to provide a diamine derivative, a process for producing the same, and a plant disease control agent containing the above-described compound as an active ingredient. According to the present invention, a diamine derivative represented by Formula (1), a process for producing the same, and a plant disease control agent containing the above-described compound as an active ingredient are provided. In Formula, R1 represents, for example, a halogenated hydrocarbon having the carbon number of 1 to 6; R2 and R7 independently represent, for example, a hydrogen atom or a hydrocarbon having the carbon number of 1 to 6; R3 and R4 independently represent, for example, a hydrogen atom or a hydrocarbon which has the carbon number of 1 to 6 and which may be substituted, or represent a cycloalkyl group having the carbon number of 3 to 6 including a carbon atom bonding to R3 and R4; R5 and R6 independently represent, for example, a hydrogen atom or a hydrocarbon group having the carbon number of 1 to 6; and R8 represents an arylalkyl group which may be substituted, an aryl group which may be substituted, or a heteroaryl group which may be substituted.
