【摘要】 【目的】筛选防控稻曲病的有效药剂，并对早期报道有效药剂的稳定性作出评判，为稻曲病防控合理选择药剂提供科学依据。【方法】分别选用曾报道对稻曲病防效良好的3种杀菌剂和曾报道对稻曲病防效不佳的1种杀菌剂及未在稻曲病上试验过的1种杀菌剂，进行田间防效对比试验，测定其对稻曲病的防治效果。【结果】于水稻黄熟期调查，防效以125 g/L氟环唑悬浮剂和24%腈苯唑悬浮剂较好，达80%以上；50%醚菌酯水分散粒剂次之，其他药剂防效不理想。【结论】24%腈苯唑悬浮剂与125 g/L氟环唑悬浮剂这两种杀菌剂对稻曲病防效稳定，当前仍适宜作为稻曲病防治的主推药剂在生产上使用，50%醚菌酯水分散粒剂可考虑作为备用药剂酌情使用。更多还原

【Abstract】 [Objective] This study was conducted to screen effective fungicides for the control of rice false smut, and evaluate the stability of effective fungicides reported earlier, providing scientific basis for rational selection of fungicides for control of false smut. [Method] Three fungicides reported to have good control effects on rice false smut, one fungicide reported to have poor control effects on false smut, and one fungicide not tested on false smut, were selected to carry out the comparative test of control effects on rice false smut in fields to determine their control effects on false smut. [Results] The investigation results at rice ripening period showed that 125 g/L epoxiconazole suspension concentrate and 24% fenbuconazole suspension concentrate were the best control fungicides, with the control effect more t han 80%, followed by 50% kresoxim-methyl water-dispersible granule, but other fungicides were not ideal. [Conclusion] Two fungicides, 24% fenbuconazole suspension concentrate and 125 g/L epoxiconazole suspension concentrate,had stable control effects on false smut, and are still suitable for use in rice production as the main agent for false smut control. 50% kresoxim-methyl water-dispersible granule could be considered as a standby agent for appropriate use.更多还原
