title: Alkylthiophenylureas with phytotoxic activity.
abstract: A series of 1-(p.alkylthio)phenylureas variously substituted on the N atom in position 3 (substances I leads to XXXVII) has been prepared and studied for pre- and post-emergence phytotoxicity. Some compounds were found to have high activity; in particular some 1-(p.alkylthio)phenyl-3-dimethylureas showed high activity even at very low doses (2 kg/ha).
