摘要:

为探讨中国野燕麦群体是否已对除草剂麦极产生抗药性,于2008—2010年连续3年在河南、安徽、江苏省的部分麦区进行野燕麦群体的采集,选用瑞士先正达公司生产的麦极15%可湿性粉剂,采用温室整株植物测定法检测野燕麦群体对麦极抗药性的发生情况。试验结果表明,在2008年的抗性检测中,河南、安徽、江苏3省的抗性植株比例分别为:6.94%、8%、11.22%;2009年的抗性检测结果是:7.14%、7.06%、12.37%;而2010年试验所得出的抗性植株所占各群体比例分别为:7.44%、7.62%、11.5%。结果表明野燕麦群体对麦极已产生不同程度低水平抗药性。其中,江苏采样群体的抗药性比率最高,不同年度群体均超过10%。虽然目前这些群体只产生低水平抗性,但是考虑到麦极是麦田主要除草剂之一,施用剂量和频率都较高,因此,在上述地区必须加强不同作用机制除草剂的科学轮换,避免野燕麦对麦极抗药性的进一步发展。

Abstract:

The wild oat populations in Henan, Anhui, Jiangsu wheat production field were collected in 2008, 2009 and 2010. These populations were tested resistance to clodinafop-propargyl by whole plant test in greenhouse. The results showed all wild oat populations evolved low resistance to clodinafop-propargyl. Of these, the resistance frequency of wild oats populations in Jiangsu Province in 2008, 2009 and 2010 were 11.22%, 12.37% and 11.5%. The resistance frequency of wild oat populations in Henan Province, Anhui Province were 6.94%, 8% in 2008, 7.14%, 7.06% in 2009 and 7.44%, 7.62% in 2010. Compared with other populations, wild oat populations in Jiangsu Province was comparatively high. Although these populations revolved low resistance, clodinafop-propargyl was one of the most primary herbicides in these fields with high usage and frequency. So herbicide rotation must be taken into consideration in these fields.
