鲁西北地区5种除草剂防除玉米田杂草的田间药效

Control Efficiency of Five Kinds of Herbicides on Weeds in Maize Field in Northwestern Shandong

[目的]明确鲁西北地区5种除草剂对玉米田杂草的防除效果。[方法]采用茎叶喷雾施药,通过田间药效试验研究75%烟嘧磺隆水分散粒剂、20%硝磺草酮可分散油悬浮剂、70%氨唑草酮水分散粒剂、48%硝磺草酮·莠去津可湿性粉剂和52%烟嘧磺隆·莠去津可湿性粉剂对玉米田杂草的防效及对玉米的安全性。[结果]5种药剂都能够有效地防除玉米田杂草并对玉米具有较好的安全性。[结论]试验结果为5种除草剂的大面积推广应用提供了理论依据。

[Objective] The aim was to clear control efficiency of five kinds of herbicides on weeds in maize field in Northwestern Shandong. [Method] The control effect and security of 75% nicosulfuron WG, 20% mesotrione EC, 70% amino ethyl ketone WG, 48% mesotrione· atrazine WP and 52% nicosulfuron· atrazine WP by using methods of stems-leaves spraying and regular survey.[Result] All the five herbicides had good control against weeds and security for corn.[Conclusion] The results provide theoretical basis for the extensive application of the five herbicides.
