为探讨吡草醚防除小麦田阔叶杂草的生物活性及其对小麦的安全性,山东省农科院植保所等单位研究人员采用室内生物活性测定法,研究了吡草醚对我国北方小麦田常见5种阔叶杂草的除草活性及对3个小麦品种的安全性。结果表明:吡草醚对播娘蒿、荠菜和麦瓶草的防效较好,GR_(90)值分别为 In order to investigate the biological activity of indoxacarb against broadleaf weeds in wheat field and its safety to wheat, the researchers of Shandong Institute of Plant Protection and other units adopted the indoor bioassay to study the effects of indoxyl Herbicidal activities of five broadleaf weeds in wheat field and their safety to three wheat varieties. The results showed that the control effect of Pyriflavone on Artemisia selengensis, Shepherd’s purse and Maitake grass was better. The values ​​of GR_ (90) were
