设置0.01%芸苔素内酯SL（芸天力）+常规杀菌（处理3）、0.01%芸苔素内酯SL+9%吡唑醚菌酯AS（芸乐收）+常规杀菌（处理4）、常规杀菌（处理2）及喷清水（处理1）4个处理，比较了不同处理对水稻抗病性及产量的影响。结果表明，处理3和处理4不仅能有效增强水稻对纹枯病和稻曲病的抗性，还能提升产量，与常规杀菌处理（处理2）相比，对水稻纹枯病和稻曲病的防效分别提升5.66%～21.7%和9.13%～20.55%，增产22.33%～24.59%。因此，在使用常规药剂的基础上可以增用0.01%芸苔素内酯SL或9%吡唑醚菌酯AS，能获得更好的防效和更高的产量。

Four treatments[treatment 3, 0.01% brassinolide SL （Yuntianli） +conventional bactericide; treatment 4, 0.01% brassinolide SL+9% pyraclostrobin AS（Yunleshou） + conventional bactericide; treatment 2, conventional bactericide; treatment 1, spray water] were designed, the effects of different treatments on disease resistance and yield of rice were compared in this experiment. The results showed that treatment 3 and treatment 4 could not only enhance the resistance of rice to sheath blight and rice smut, but also increase the yield of grain. Compared with treatment 2, the control effects on rice sheath blight and rice smut of treatment 3 and treatment 4 were improved by 5.66%~21.7% and 9.13%~20.55%, respectively, and the yield increased by 22.33%~24.59%. Therefore, on the basis of the use of conventional agents, 0.01% brassinolide SL or 9% pyrazole AS can be added, which could obtain higher yield.
