草甘膦剂量效应研究机构近日证实,美国内布拉斯加州东南部发现一种抗草甘膦的普通豚草(Ambrosia artimisiifolia),该种群生存的耐受剂量是草甘膦农药标签建议使用量的八倍。虽然这不算是高抗性,但很显然,草甘膦已经不能有效防控这种普通豚草。内布拉斯加州是首次发现抗草甘膦普通豚草。早在2004年,美国14个州均报道出现耐草甘膦普通豚草,其中13个州是在大豆作物中发现此杂草。内布拉 Glyphosate dose-response research agency recently confirmed that the United States Nebraska found in the southeast of a common glyphosate-resistant ragweed (Ambrosia artimisiifolia), the survival of the population tolerance dose is recommended glyphosate pesticide labeling Eight times. Although this is not considered highly resistant, it is clear that glyphosate is no longer effective against this common ragweed. Nebraska was the first to find glyphosate-resistant common ragweed. As early as 2004, glyphosate-tolerant common ragweed was reported in all 14 U.S. states, of which 13 were found in soybean crops. Nebraska
