摘要
2010～2011年,分别在田间和盆栽条件下研究了甲柳.三唑酮和立克秀拌种对小麦出苗和病虫害防控效果的影响。结果表明,两种药剂拌种均会导致小麦出苗延迟、出苗率和生长速率下降。甲柳.三唑酮拌种浓度增大,对出苗抑制作用增强;立克秀拌种浓度增大,出苗受抑制变化不明显。2种药剂混合拌种对出苗的抑制作用大于单药剂拌种。甲柳.三唑酮拌种可以显著降低虫咬死株率,立克秀拌种对小麦生育后期白粉病的防控效果不佳。根据区域特点选择适宜的拌种剂,同时采用正确方法拌种对于小麦正常出苗和提高病虫防控效果具有重要意义。
Form 2010 to 2011,the effect of seed dressing agents on wheat seedling emergence and pests and diseases control was studied under pot and field condition respectively.The results showed that seed dressing with isofenphos-methyl ·triadimefon or raxil would cause seedling emergence time delaying and emergence rate and growth rate decreasing.With the dressing concentration of isofenphos-methyl · triadimefon increasing,the inhibition effect to seedling emergence would enhanced.Mixing dressing with isofenphos-methyl · triadimefon and raxil had more inhibition effect on seedling emergence than only one agent.Dressing with isofenphos-methyl · triadimefon would decrease death seedling rate bitten by pests significantly.The control efficiency of raxil to powdery mildew appearing in filling stage was not good.Choosing appropriate agents according to regional characters and adopting right dressing methods could increase seedling emergence quality and control efficiency to pests and diseases.
