摘要: 文章明确30g/L甲基二磺隆可分散油悬浮剂(OD)和8%炔草酯OD对小麦田禾本科杂草的防效及对小麦的安全性,为两种除草剂的实际应用提供理论依据。药后30d,30g/L甲基二磺隆OD在12.4g/hm2剂量下对野燕麦、雀麦的鲜重防效均达到85.00%以上;8%炔草酯OD在45.0g/hm2剂量下对野燕麦的鲜重防效较好,为94.58%,对碱茅防效为68.71%。各药剂处理下的小麦未产生不良影响,且产量与空白对照相比均有所增加。

Abstract: The herbicidal efficacy and security of two herbicides,30 g/L mesosulfuron OD and 8%clodinafop-propargyl OD,were studied,to provide a theoretical basis for the practical application of the two herbicides.The result showed that in the 30 days after using the herbicides,the effect of 30 g/L mesosulfuron OD at the dose of 12.4 g(a.i.)/hm2 for Avena fatua L.and Bromus japonicus Thunb.were above 85.00%on biomass reductions.The effect of 8%clodinafop-propargyl OD at the dose of 45.0 g(a.i.)/hm2 on control of Avena fatua L.was 94.58%.The control efficiency on Puccinellia parlatore was 68.71%.The two herbicides are safe for wheat and effectively control weeds for increasing production.
