Abstract: Novel biocidal compounds have the general structural formula ##STR1## wherein n is 0, 1, or 2 and R is alkyl, alkylcarbalkoxy, cyclohexyl, halophenyl, benzyl, N,N-di-lower alkyl carbamoyl, hexamethyleneimino carbonyl, pyrimidyl, lower alkyl substituted pyrimidyl, benzimidazole, lower alkyl substituted imidazole, benzothiazole and O,O-di-lower alkyl thiophosphoryl; with the proviso that when n is 0, R is other than alkyl or cyclohexyl.
Abstract: N-substituted benzothiazolines and benzoxazolines having the formula ##STR1## have been found to be effective as herbicides and plant growth regulants.
