A herbicide containing a 2-trifluoromethylpyrimidin-6 (1H) -one derivative represented by the general formula (1) as an active ingredient is provided. (In the formula (1), R 1 represents a fluoroalkyl group having 1 to 6 carbon atoms, R 2 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, and R 3 may be a hydrogen atom or substituted. Represents a good alkyl group having 1 to 6 carbon atoms, R 4 represents a hydrogen atom, an optionally substituted alkyl group having 1 to 6 carbon atoms, Represents an optionally substituted alkenyl group having 3 to 6 carbon atoms, an optionally substituted alkynyl group having 3 to 6 carbon atoms or an optionally substituted aralkyl group having 7 to 11 carbon atoms, and X represents hydrogen. An atom or a halogen atom is represented, and W represents an oxygen atom or a sulfur atom. ) [Selection figure] None |
