A series of imidazo[2,1-b]thiazole derivatives including aldehydes (I-XXIX), oximes (XXX-XL) and 2,4-dinitrophenyloximes (XLI-LIII) were prepared and tested as potential herbicides. Many compounds were active in paddy field treatment, sand and in water culture. In upland condition, a number of dinitrophenyloximes proved herbicides in postemergence treatment, whereas in preemergence only compounds XVI, XXV and XLVIII showed some degree of activity.
