The present application discloses herbicidal substituted-phenyl-1,2,4-Triazol-5(1H)-thiones and -ones, herbicidal compositions containing these compounds, methods of preparing them, and methods for controlling undesired plant growth by preemergence and/or postemergence application of the herbicidal compositions to the locus where control is desired. The herbicidal compounds are compounds of the formula ##STR1## wherein: Ar is selected from ##STR2## R is selected from haloalkyl; R.sup.1 is selected from alkyl;
