A new class of herbicidal compounds consisting of 1-alkyl- and 1,1-dialkyl-3-(3,4-substituted-5-isothiazolyl)ureas and N-(3,4-substituted-5-isothiazolyl)-alkanamides in which the 3-substituent consists of alkylthio, alkylsulfinyl, and alkylsulfonyl, and the 4-substituent consists of cyano, and carbamoyl, exhibits preemergence and postemergence herbicidal activity, controlling effectively the growth of a wide spectrum of grassy and broad-leaved plant species. The synthesis of members of this class is described in detail, and the utility of representative compounds is exemplified.
