去年夏天,加拿大安大略南部地区免耕大豆田中杂草频现,严重影响了作物的产量。其中最突出的杂草是加拿大飞蓬,这也是草甘膦抗性问题中出现的最新挑战。除草剂抗性问题已形成恶性循环,安大略地区需要找出一个创新的解决方案。继20世纪80年代发现了抗三嗪类除草剂的杂草之后,每类新出现的防效好的除草剂在使用几年之后都会出现抗性问题。草甘膦于1974年研发成功,1986年耐草甘膦的
Last summer, frequent weeds in no-till soybean fields in southern Ontario, Canada, severely affected crop yields. One of the most prominent weeds is Canadian scrophulariaceae, which is also the latest challenge in glyphosate resistance. Herbicide resistance has become a vicious circle, and the Ontario region needs to find an innovative solution. Following the discovery of weeds resistant to triazine herbicides in the 1980s, resistance problems have emerged with each emerging class of well-controlled herbicides after years of use. Glyphosate was successfully developed in 1974 and glyphosate-tolerant in 1986
