| 摘 要： | 测定了丁草胺、乙氧氟草醚对稗草Echinochloa crusgalli （L.） Beauv及以刺苋Amaranthus spinosus L.、繁缕Stellaria media （L.） Cyr.为代表的阔叶杂草的毒力,并证实将两者混配成丁乙水乳剂对稗草及阔叶杂草具有明显的协同增效作用,其中,质量比为14∶1混剂的共毒系数（CTC）分别为164.0和288.5。田间试验亦证明混剂能提高药效,扩大杀草谱,延长持效期,具有较显著的除草作用。

| Abstract: | The activities of butachlor and oxyfluorfen to Echinochloa crusgalli (L.) Beauv, Amaranthus spinosuo L. and Stellaria media (L.) Cyr. were studied. The results showed that the mixtures of butachlor and oxyfluorfen can improve the activities to weeds. The CTC of the mixture of 14∶1 were 164.0 and 288.5 to Echinochloa crusgalli (L.) Beauv and broadleaf weeds respectively. The results of field experiments showed that the mixture of the two herbicides could improve the control effect to weed, broaden the control spectrum significantly compared with the single herbicide. The rice yield also increased significantly with the application of the mixtures. |
