The results showed that 17% Tetrafluoro-azoxystrobin suspension 615ml / hm2, 555ml / hm2 were applied once at the end of rice booting stage, once every 7 days and control effect on sheath blight of rice at 14 days after the last application Were 75.62% and 71.11% respectively, which was significantly different from that of 20% Jinggangmycin water-soluble powder at 900g / hm2 control efficiency (59.14% control efficiency), and could be used as an alternative pesticide to control rice sheath blight in the future.
