摘　　要：[Objective]The paper was to screen fungicides with strong antifungal activities against Fusarium oxysporum Schlecht,and to provide a theoretical basis for controlling root-rot of Rhodiola sachalinensis A. Bor. [Method]Using mycelial growth rate method,the indoor antifungal activities of eight fungicides against F. oxysporum were studied. [Result]Eight fungicides at different concentrations performed different antifungal activities. Toxicity test results showed that the EC_（50） value of Difenoconazole was the smallest（ 4. 267 4 mg/L）,followed by Mancozeb（ 6. 952 5 mg/L）,and the EC_（50） of Thiram,Captan and Procymidone were relatively small from 25 to 50 mg/L. [Conclusion]Among eight fungicides,Difenoconazole had the best antifungal effect against F. oxysporum,while Mancozeb,Thiram,Captan and Procymidone had good control effects as well.[Objective]The paper was to screen fungicides with strong antifungal activities against Fusarium oxysporum Schlecht,and to provide a theoretical basis for controlling root-rot of Rhodiola sachalinensis A.
