| 中文摘要: |
| 2011 年采用大田药效试验的方法，研究60%丁草胺窑噁草酮乳油防除水稻旱直播田杂草的防除效果、最
佳使用剂量及安全性。该药剂在水稻旱直播田播后苗前土壤喷雾处理，推荐使用药量为720耀900 g a.i./hm2，可有效地
防除稗草、千金子等禾本科杂草及碎米莎草、水虱草等莎草科杂草。在推荐使用剂量内对水稻安全，高浓度处理会产
生部分药害，后期可以恢复。 |
| 英文摘要: |
| By field efficacy test method, this study determined the effect of 60% Butachlor+Oxadiazon EC on weeds
and investigated the close and rice safety in direct seeded rice field during 2011 in South China. The results showed that
the control efficiency on grasses weeds Echinochloa crusgalli (L.) Beauv., Leptochloa chinensis (L.) Nees and cyperaceae
weeds Cyperus iria L., Fimbristylis miliacea (L.) Vahl was good by 720耀900 g a.i./hm2 60% Butachlor+Oxadiazon EC
before rice seedling emergence in the field. The rice was safety with the recommended dose, but phytotoxicity would appear
with higher concentration and latter could return. |
