A process for inhibiting plant growth comprising contacting a plant or its growth area with an effective amount of certain para-halophenyl substituted triazolines. A series of certain novel substituted tetrahydro-oxothiazolo-triazolium compounds useful as herbicides. A novel process for preparing 3-phenyl-4-oxo-1,2,3-triazoline by contacting benzenediazoniumchloride and an .alpha.-amino carboxylic acid and cyclodehydrating the triazene produced using acetic anhydride and pyridine.
