Abstract Sixteen new 3‐arylaminomethyl‐5‐(2,4‐dichlorophenyl)‐1,3,4‐oxadiazole‐2‐thione and six 3‐alkyl aryl alkyl‐5‐(2,4‐dichlorophenyl)‐1,3,4‐oxadiazole‐2‐thiones were synthesised and characterised by their sharp melting points, elemental analysis, ir, 1 H nmr and mass spectra. These substituted oxadiazolethiones were screened for their fungitoxic properties. Most of the compounds showed toxicity against two test organisms, Curvularia verruciformis and Alternaria tenuis . The degree of inhibition ranged from 38‐‐100% for a few compounds.
