A number of 5-Aryl-2-(5-arylamino-1, 3, 4-thiadiazol-2-yl amino) -1, 3, 4-thiadiazole (3) have been prepared by the cyclo dehydration of 1-Aryl-6-(5-aryl-1, 3, 4-thiadiazol-2-yl) -2-thioureas (2) which was prepared by the reaction of 4-(5-Aryl-1, 3, 4-thiadiazol-2-yl)- semicarbazides (1) phenyl isothiocynate in presence of ethanol. These compounds have been evaluated for their fungicidal activity against Pyricularia oryzae, Sphaeotheca fuliginea, Phytopthora infestans and Pseudopernospora cubensis.
