环庚草醚防除稻田杂草的试验研究

Studies on the Control of Weeds in Rice Fieldwith Cinmethylin

在秧苗移载后５天，每公顷用１０％环庚草醚乳油３００毫升，或１０％环庚草醚乳油１５０毫升＋１０％苄嘧黄隆可湿性粉剂２２５克，用毒土法撒施，对水稻本田中的稗草、牛毛毡、异型莎草、鳢肠、丁香等杂草的防效可稳定在９０％以上，且在此剂量下，对水稻及下茬麦子是安全的。

The control effects of cinmethylin and its mixtureon weeds in rice field were tested.Cinmethvlin 10%EC at300ml/ha or the mixture of cinmethylin 10%at 150ml/ha andbensulfuron-methyl 10%WP at 2.25g/ha at 5 day after trans-planting had significant effect of controling Echinochlco crus-galli.Eleocharis yokoscensis,Cyperus difformis,Eclipta,Pros-trata and Ludwigia prostrata. The control efficacy of thesetreatments was over 90%. The herbicides were safe to the growth of rice and following wheat.
