Abstract
[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.关键词
