Abstract：Both dimethyl disulfide（DMDS） and dazomet（DZ）were applied to cucumber in greenhouse at Beijing Shunyi District，where soil borne diseases were serious. DZ was applied with a small rotary tiller and DMDS，by injection method. Then the soil surfase was covered with completely impermeable film. The effects of DMDS and DZ on cucumber main soil borne diseases and cucumber growth and yield were compared. Results indicated that both DMDS and DZ could effectively control Meloidogyne spp.，Phytophthora spp. and Fusarium spp.，the control efficiency were 84.29%，75.99% and 79.94%，respectively at DMDS usage of 40 g·m-2，and 80.30%，92.36%，92.27%，respectively at DZ usage of 30 g·m-2. Compared with the control group，DMDS and DZ fumigation increase the net income of cucumber by 66%-85% and 65%-71%，respectively.
