[目的]筛选防治稻曲病的最佳药剂以及防治适期.[方法]以杂交水稻组合88S/0293为供试材料,在水稻破口前5 d和破口抽穗初期各施药一次,通过田间药效试验研究不同药剂对稻曲病的防治效果.[结果]30%爱苗乳油225 ml/hm2、43%好力克悬浮剂270 ml/hm2和25%富力库微乳剂450 ml/hm2防治效果最好,其次为20.67%万兴乳油300 ml/hm2和2.5%纹曲宁乳油3 750 ml/hm2,15%粉锈宁可湿性粉剂对稻曲病防治效果差.30%爱苗乳油、43%好力克悬浮剂、25%富力库微乳剂对水稻有明显的增产作用.爱苗对稻曲病的防治适期为水稻破口前5 d施一次药为佳.[结论]该研究为稻曲病的有效防治奠定了基础.

[Objective]The aim was to screen the optimum fungicides and period for controlling rice false smut. [Method]With hybrid rice combinations 88S/0293 as tested material, the fungicides were applied once in each first 5 d before crevasse stage and early heading stage, and the control effects of different fungicides on rice false smut were studied by field efficacy test. [Result]The control effects of 30% Armure EC at 225 ml/hm2, 43% Haolike SC at 270 ml/hm2 and 25% Fuliku emulsion at 450 ml/hm2 were best, followed by 20.67% Wanxing EC at 300 ml/hm2and 2.5% Wenquning EC at 3 750 ml/hm2, while that of 15% Triadimefon WP had poor control effect on rice false smut. 30% Armure EC, 43% Haolike SC and 25% Fuliku emulsion had obvious yield increasing effect on rice. The optimum period of Armure controlling rice was the first 5 d before rice crevasse stage and applied once was best. [Conclusion]The research laid the foundation for the effective control for rice false smut.
