Abstract
[Objective] The aim was to analyze the field efficacy of four fungicides against rice blast and rice sheath blight.[Method] Susceptible variety Xiangzaoxian 24 was taken as tested material,and the field efficacy of four fungicides like 32.5% Amimiaoshou SC,30% Armure EC,75% Nadiwen WG and 75% Daoyan WP against rice blast and rice sheath blight were determined.[Result] 75% Daoyan WP at 300 g/hm2 had the best field efficacy against rice blast and rice sheath blight.[Conclusion] The research result provides reference for the control of main diseases in rice.
