摘要：
As new compounds are provided 2-(4',6'-di-substituted pyrimidine-2'-yl)oxy- or thio-benzoic acid derivatives of the formula ##STR1## wherein R is hydrogen, hydroxy, alkoxy, alkenyloxy, alkylthio or other substituents, R.sup.1 and R.sup.2 are each a halo, alkyl, alkoxy or other substituents; and X is oxygen or sulfur atom. These new compounds are useful as herbicidal agent effective to inhibit the growth of annual weeds and also perennial weeds predominant in irrigated fields of aquatic rice plants and in plowed fields.
