Abstract
An oxazolidinedione compound represented by the formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, a cycloalkyl group having 3 to 5 carbon atoms, an alkenyl group having 3 to 5 carbon atoms, an alkynyl group having 3 to 5 carbon atoms or an alkoxycarbonyl group having 1 or 2 carbon atoms in the alkyl moiety thereof, R.sup.2 represents an alkyl group having 3 to 5 carbon atoms or a cycloalkyl group having 3 to 5 carbon atoms, and X represents a chlorine atom or a fluorine atom; a process for preparing the same; and a herbicidal composition comprising the oxazolidinedione compound as an active component are disclosed. The above oxazolidinedione compounds exhibit a high selectivity for useful crop plants and a strong herbicidal activity with respect to various noxious weeds.
