| 中文摘要: |
| 噁草酮对阳光的分解有良好的耐性,用25％乳油2.5L/hm~2防除旱直播稻田杂草,施药后曝晒25d左右药效开始下降,曝晒35～40d的防效仍保持在80％以上,45d后防效较差。施药后等雨或等水灌溉出苗,防除效果好。土壤湿润有利于药效的发挥。 |
| 英文摘要: |
| It was found that oxadiazon was resistant to photodecomposition. When oxadiazon (25% EC) was applied at the rate of 2. 5 1/ha in dry seeded rice field, its effectiveness remained over 80% after it was exposed to sunlight for 35-40 days. It was also observed that the bioactivity of oxadiazon against target weeds began to decline 25 days after application, and its activity was badly affected after 45 days. Rain and irrigation after oxadiazon spray improved its herbicidal effectiveness. |
