ABSTRACT:
A new class of herbicidal compounds consisting of N,N-dialkyl-N'-(substituted-5-isothiazolyl)-N'-acylureas in which the 3-substitutent on the isothioazole moiety consists of alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, and dialkylamino, and the 4-substituent on the isothiazole moiety consists of cyano, alkoxycarbonyl, and nitro; and in which the nitrogen atom of the N,N-dialkylurea to which the isothiazolyl moiety is bonded, is also bonded to an acyl moiety, exhibits outstanding 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.
