In order to confirm the control effects and the optimum dosages of flutolanil+ azoxystrobin 20%WG and tebuconazole + azoxystrobin 75% WG for rice sheath blight, the field effect trials were carried out in 2012 while the rice sheath blight entering beginning-period and peak period. The results showed that flutolanil +azoxystrobin 20% WG 750-1 500 g/hm2 and tebuconazole + azoxystrobin 75% WG 150-300 g/hm2 had good efficacies on rice sheath blight, the control effects exceeded 90%after the first spraying and were more than 95%after the second spraying. The control effects had no significant difference compared with trifloxystrobin +tebuconazole 75%WG and thifluzamide 240 g/L SC, but were better than difenoconazole+propiconazole 300 g/L EC, tebuconazole 43%SC and validamycin 20%AS.
