(57) [Problem] To provide a herbicide which can be synthesized industrially advantageously, has a lower dose, is highly effective, has high safety, and has high selectivity to crops. SOLUTION: The general formula [I] [Wherein, R 1 represents a C 1-6 alkyl group, and R 2 represents R 6 represents a 1-6 alkylthio group or a C 1-6 alkylsulfonyl group, R 3 and R 4 represent a hydrogen atom or a C 1-6 alkyl group, and R 5 represents a hydrogen atom or a compound represented by the formula: (In the formula, R 6 represents a halogen atom, a C 1-6 alkyl group or a C 1-6 alkoxy group, and n represents 0-5.) One group selected from the group represented by the following formula: Represents R 7 , R 8 , R 9 and R 10 represent a hydrogen atom or a C 1-6 alkyl group. (R 7 or R 8 ) and (R 9 or R 10 ) may form a single bond. Or a salt thereof, a production intermediate thereof, and a herbicide containing at least one of them. |
