[目的]通过田间药效试验验证,36%唑草酮.苯磺隆水分散粒剂可防除冬小麦田一年生阔叶杂草,并有良好的增产效果。[方法]在小麦拔节期进行茎叶喷雾施药。[结果]药后20 d总株防效可达81.4%～88.4%,药后40 d鲜质量总防效可达82.6%～90.4%,小麦增产率为12.6%～18.0%。[结论]该药剂对小麦安全,适宜推荐剂量为32.4～43.2 g/hm2。 [Objective] The objective of this study was to verify that 36% oxacillin and tribenuron-methyl water dispersible granule can control annual broadleaf weeds in winter wheat field with good yield-increasing effect. [Method] The stems and leaves were sprayed at wheat jointing stage. [Result] The control efficacy of the whole plant was 81.4% ~ 88.4% 20d after the drug treatment. The control effect of the fresh weight was 82.6% ~ 90.4% after 40 d and the yield of wheat was 12.6% ~ 18.0%. [Conclusion] The medicament was safe for wheat and the suitable recommended dose was 32.4 ~ 43.2 g / hm2.
