Abstract：The tomato late blight isan important diseases in tomato production，which has a significant impact onits yield and quality.In order to select highly effctive fungicides to control the tomato lateblight，10 treatments were set，andthe disease index，preventionand control effct，and safety were measured.The result showed that alltreatments had acertain prevention and control efecton the disease.After the first application for 10 days，the prevention and control effect of each drug exceeded 54% ，and 1O days after the second application， the control effect exceeded 66% . After spraying two times， the control efficacy of oxathiapiprolinazoxystrobin were 72.87% and 85.69% ，the fluopicolide -cyazofamid were 71.46% and 85.21% ，so the two fungicides could be alternately used to control the disease in the future.
