| 摘 要： | 目的]筛选出烟草向日葵列当有效的化学防控药剂并确定其最佳浓度。方法]通过大田试验研究9种不同化学药剂的单剂和混配对烟草向日葵列当的防治效果。结果]3.75 L/hm2二甲戊灵对烟草向日葵列当的防效为63.83%;1.50 L/hm2精异丙甲草胺和3.75 L/hm2氟乐灵的防效均为59.57%,但从前期的药害指数来看,1.50 L/hm2精异丙甲草胺和3.75 L/hm2氟乐灵的药害要小于3.75L/hm2二甲戊灵。结论]1.50 L/hm2精异丙甲草胺和3.75 L/hm2氟乐灵2种药剂值得进一步推广。

| Abstract: | Objective] To screen out effective chemicals for controlling O.cumana Wallr on tobacco and make sure its optimal dosage.Method] We studied the control effects of single and mixed forms of nine kinds of herbicides against O.cumana Wallr.Result] The control effects of 3.75 L/hm2 Pendimethalin,1.50 L/hm2 (S)-Metolachlor and 3.75 L/hm2 Trifluralin were 63.83％,59.57％ and 59.57％,re spectively.But seeing from the early phytotoxicity index,the phytotoxicity of 1.50 L/hm2 (S)-Metolachlor and 3.75 L/hm2 Trifluralin were smaller than that of 3.75 L/hm2 Pendimethalin.Conclusion] Both 1.50 L/hm2 (S)-Metolachlor and 3.75 L/hm2 Trifluralin are the suitable chemicals for controlling O.cumana Wallr. |
