Abstract: In order to control rice sheath blight and delay the onset of azoxystrobin resistance, field efficacy trials of six azoxystrobin mixtures on rice sheath blight was carried out. The results showed that, flutolanil?azoxystrobin 20% WDG, thiophanate-methyl?azoxystrobin 75% WDG, tebuconazole?azoxystrobin 75% WDG and propiconazole?azoxystrobin 32% SC were effective in control of rice sheath blight, as well as the control effect were respectively 82.50%-86.68%, 73.87%-85.33%, 73.20%-84.75% and 73.71%-82.63%, which were higher than those of jinggangmycin 5% AS used in the production widely.
