ABSTRACT:
A tetrahydrofuran derivative represented by the following general formula [I]: ##STR1## wherein A represents direct bonding or a group represented by --B--CHR.sup.1 --(wherein B represents oxygen atom, sulfur atom or imino group; R.sup.1 represents hydrogen atom or an alkyl group); R represents hydrogen atom, halogen atom, hydroxyl group, an alkoxy group, benzyloxy group, an alkylsulfonyloxy group or a group represented by --O--COR.sup.2 (wherein R.sup.2 represents an alkyl group, a haloalkyl group, an alkenyl group, a cycloalkyl group, phenyl group, benzyl group, an alkoxy group, an alkylamino group or a dialkylamino group; X represents halogen atom; Y represents hydrogen atom or halogen atom) and the herbicide containing the same as the effective ingredient. The compounds of the present invention have exceedingly high herbicidal activity, and furthermore, the compounds are superior to the known similar compounds in terms of safety on crops. Thus, the compounds are useful as herbicides.
