摘　　要：2008—2009年在我国东北、华北的6个省份烟嘧磺隆防效下降的玉米田块采集80个马唐种群,在可控温室中采用整株测定法对其进行抗性检测试验。结果表明,不同用药历史玉米田的马唐种群对烟嘧磺隆已经产生了不同程度的抗药性,其中有10个种群产生的抗药性较显著。Whole - plant bioassays were conducted in 2008 - 2009 under controlled greenhouse conditions to determine the response to nicosulfuron of 80 Digitaria sanguinalis populations collected from maize fields in 6 provinces of the North and Northeast of China where efficacy of the herbicide had been declining. D. sanguinalis populations with different helbieide exposure histories had different degrees of resistance to nieosulfuron; ten of the populations were highly resistant to the herbicide.
