防治烟草向日葵列当药剂的筛选OA
Screening of Chemicals for the Control of Orobanchel cumana Wallr on Tobacco
[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,1.50L/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…查看全部>>
[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.…查看全部>>
