Control Effect of the Mixture of Fenaminstrobin and Thifluzamide against Rice Sheath Blight

[Aims] This study aims to confirm the miscibility of fenaminstrobin and thifluzamide against rice sheath blight. [Methods] The synergistic action test and whole plant test in greenhouse were used. [Results] The results indicated that the tested five mixtures showed obvious synergism effect and the mixture of fenaminstrobin and thifluzamide with the ratio of 5 to 1 offered the best antibacterial activity. The efficacy of fenaminstrobin and thifluzamide 30% SC 5# was higher than that of other formulas against rice sheath blight at the same concentration. [Conclusions] Fenaminstrobin and thifluzamide 30% SC showed good control and safety to rice seedling.
