探索了43％好力克SC与30％爱苗EC在防治稻曲病中的精准使用技术。结果表明：对于43％好力克SC而言，在移栽前施用无效，在破口期至齐穗期施用均能取得较好的防效；对于30％爱苗EC来说，在移栽前施用有预防效果，在破口前期施用的防效优于在破口期和齐穗期施用的。综合考虑防治效果和用药成本等因素，推荐在破口前7d和破口期各施用43％好力克SC 129．00 g/hm2一次或只在破口期施用43％好力克SC 193．50 g/hm2一次；在破口前7 d和破口期各施用30％爱苗EC 90．00 g/hm2一次或只在破口前7 d施用30％爱苗EC 135．00 g/hm2一次。

The precise use technologies of two kinds of chemical fungicides (43% Horizon SC and 30%Armure EC) for the control of rice false smut were explored.The results showed that the application of 43%Horizon SC before transplanting was invalid, but its application from rupturing stage to full heading stage all could obtain better control effect on rice false smut.The application of 30%Armure EC before transplanting had prevention effect on this disease, and its application at earlier rupturing stage had better control effect than that at rupturing stage or at full heading stage.Based on the overall consideration of control effect, fungicide ap-plication cost and so on, the author recommended that: applying 43% Horizon SC 129.00 g/hm2 one time on the 7th day before rupturing and at rupturing stage respectively, or applying 43%Horizon SC 193.50 g/hm2 one time only at rupturing stage;applying 30%Armure EC 90.00 g/hm2 one time on the 7th day before rupturing and at rupturing stage respectively, or applying 30% Ar-mure EC 135.00 g/hm2 one time only on the 7th day before rupturing.
