Abstract Fungicidal activities of cis-1，3-dichloropropene and trans-1，3-dichloropropene in the laboratory were evaluated for further application in the fields．Fungicidal activities of cis-1，3-D and trans-1，3-D on 8 kinds of plant pathogen fungi were tested in the laboratory with the improved growth rate method．The laboratory results showed that fungicidal activities of the 2 fumigants were different and the values of EC50 were trans-1，3-D＞1，3-D＞cis-1，3-D．Cis-1，3-D was better than trans-1，3-D against the plant pathogen fungi，but further studies on field trials should be conducted．
