摘要
[目的]探讨苯唑草酮对玉米田杂草的防除效果。[方法]研究苯唑草酮在单用以及与莠去津混用对玉米田禾本科杂草、阔叶杂草的防除效果。[结果]无论是在杂草低叶龄(3~4叶)期施药还是在在杂草高叶龄(6~8叶)期施药,均能有效防除玉米田间杂草,且对玉米高度安全。[结论]苯唑草酮对杂草高效、广谱,值得推广。
[Objective] The aim was to explore control effect of topramezone against weeds in maize field. [Method] The control effects of single topramezone and its mixture with atrazine against weeds in maize field were studied. [Result] Whether applying at low leaf age（ 3-4 leaves） of weed or applying at high leaf age（ 6-8 leaves）,the topramezone could control weeds in maize field,and was highly safe to maize.[Conclusion]The topramezone has some advantages of high efficiency and wide spectrum,so it is worthy to popularize.
