Disclosed is a novel herbicide. A haloalkylsulfonanilide derivative represented by formula (1) or an agrochemically acceptable salt thereof. In formula (1), Z represents -C(R9)(R10)- or -N(R11)-; A represents an oxygen atom, a sulfur atom, or N(R12)-; W represents an oxygen atom or a sulfur atom; m represents an integer of 0 to 3; n represents an integer of 0 to 3, and m+n is 1 to 3; R1 represents halo-C1-C6 alkyl; R2 represents a hydrogen atom, C1-C6 alkyl, or the like; R3 and R4 each independently represent a hydrogen atom, C1-C6 alkyl, or the like; R5, R6, R7, R8, R9, and R10 each independently represent a hydrogen atom, halogen, C1-C6 alkyl, or the like; R11 and R12 each independently represent a hydrogen atom, C1-C6 alkyl, halo-C1-C6 alkyl, or the like; X's each independently represent a hydrogen atom, halogen, C1-C6 alkyl, or the like. |
