不同玉米品种对烟嘧磺隆敏感性及施药方法

Sensitivity of Different Corn Lines and Spraying Methods to Nicosulfuron

不同玉米品种对烟嘧磺隆的敏感性存在较大差异。豫玉26、郑单18和浚单20抗药性较强,郑单958、农大108、浚单18、新单23有较强的耐药性;济单7号和登海1、9、11号比较敏感。采用半定向喷雾可有效地解除烟嘧磺隆对玉米药害的影响。

The different corn lines have a significant difference to nicosulfuron. Yuyu 26, Zhengdan 18, Xundan 20, Zhengdan 958, Nongda 108, Xindan 18 and Xindan 23 have stronger resistance. Jidan 1, Denghai 1, Denghai 9 and Denghai 11 are comparatively sensitive. The method of half orientated spray techniques is able to effectively relieve the harms of nicosulfuron to different corn lines.
