摘  要：
为明确环磺酮、特丁津联合作用除草效果和35%环磺酮·特丁津OD对玉米田一年生杂草的防除效果以及对玉米的安全性,采用茎叶喷雾法测定2种除草剂室内联合作用试验,并对筛选的35%环磺酮·特丁津OD进行田间药效试验。结果显示,环磺酮、特丁津以1∶6质量比复配对玉米田一年生杂草的联合作用效果较好,35%环磺酮·特丁津OD的推荐使用剂量为420～630 g a.i./hm~2,施药36 d后对杂草的总鲜重防效可达到93.90%～97.56%。环磺酮、特丁津复配互补性强,对马齿苋等杂草增效作用明显,35%环磺酮·特丁津OD能够有效防除玉米田一年生杂草,并对玉米安全。

摘  要：
The efficacy on annual weeds and crop selectivity of the combination of tembotrione and terbuthylazine was compared to that of the formulated mixture(tembotrione·terbuthylazine 35% OD). Foliar spraying was used in the laboratory to assess the efficacy of the mixture and the formuation was tested in the field. The mixture of tembotrione and terbuthylazine at a mass ratio of 1 ∶6 controlled annual weeds better in corn. The recommended dose of tembotrione·terbuthylazine 35% OD was 420～630 g a.i./hm~2. Efficacy based on fresh weight reduction reached to 94%～98% after 36 days. Tembotrione and terbuthylazine are highly complementary in mixture, with an evident synergistic effect on Portulaca oleracea. Tembotrione·terbuthylazine 35% OD effectively controlled annual weeds and was selective to corn in the field.
