摘要
【目的】验证26．7％噻酮磺隆·异曝唑草酮悬浮剂对玉米田杂草的药效、杀草谱及对玉米的安全性。【方法】采用茎叶喷雾、定期调查的方法进行田间药效试验。【结果】药剂26．7％噻酮磺隆。异嘿唑草酮悬浮剂的杀草谱较广，包括一年生禾本科杂草及大部分阔叶杂草。施药后30aN查，其对各种杂草株数综合防效为89．0％-99．5％。鲜质量防效达94．5％～99．9％。【结论】26．7％噻酮·异嘿唑SC适宜使用剂量为141．75-165．38ga．i．／hm2，对水375L／hm2茎叶喷雾。
[Aims] The control efficiency and the safety of thiencabazone-methyl·isoxaflutole 26.7% SC to weeds in corn fields were analyzed. [Methods] This experiment was done by stem-leave spray and regular investigation. [Results] The results showed that the controlled weeds by thiencabazone-methyl·isoxaflutole 26.7% SC included annual grass weeds and most broad-leave weeds. Its efficiency was 89.0-99.5% after 30 d, and control efficiency of fresh weight to weeds was 94.5- 99.9%. [Conclusions] The application dose of thieneabazone-methyl·isoxaflutole 26.7% SC was 141.75-165.38 g a.i./ha. It should be diluted with 375 L water per hectare and sprayed upon the leaves and stems.
