|
摘要
[目的]比较31.9%戊唑·吡虫啉FS、27%苯醚·咯·噻虫FS和25%噻虫·咯·霜灵FS 3种复合种衣剂对小麦蚜虫和纹枯病的防治效果以及增产效果。[方法]在漯河市2个试验点进行种子包衣处理的田间防效试验。[结果]所有处理对小麦出苗均无显著影响。对纹枯病防治效果最优的是27%苯醚·咯·噻虫FS 81 g a.i./100kg种子包衣处理,其次为25%噻虫·咯·霜灵FS 75 g a.i./100kg种子包衣处理,31.9%戊唑·吡虫啉FS 127.6 g a.i./100kg种子包衣处理对纹枯病防效较差。对小麦蚜虫防治效果最优的是31.9%戊唑·吡虫啉FS 127.6 g a.i./100kg种子包衣处理,在拔节期、抽穗期和灌浆期的防效均与其他2种种衣剂处理的防效差异显著。[结论]27%苯醚·咯·噻虫FS和31.9%戊唑·吡虫啉FS可以作为主要种衣剂在河南省冬麦区推广。
[Aims] The objective of this study is to compare the control effects of 3 kinds of flowable concentrate for seed coating(FS), tebuconazole·imidacloprid 31. 9 % FS, difenoconazole·fludioxonil·thiamethoxam 27 % FS,and thiamethoxam·fludioxonil·matalaxyl 25% FS on sharp eyespot and aphids on wheat, and to evaluate effect of the three types of chemical complexes on wheat yield. [Methods] The field tests were performed by seed treatment with each of the three chemicals at two locations in Luohe, Henan. [Results] The results showed that no significant difference was found among all of the treatments on emergence of wheat seedling. The control effect on wheat sharp eyespot of difenoconazole·fludioxonil·thiamethoxam 27% FS was optimal at filling stage. The difference in the control effecttiveness of tebuconazole·imidacloprid 31.9% FS on wheat aphids was significant at elongation stage, heading stage and flowering stage, respectively. [Conclusions] Tebuconazole·imidacloprid 31.9% FS and difenoconazole·fludioxonil·thiamethoxam 27% FS could be used in Henan winter wheat area.
