Article Synopsis
- Glyphosate-resistant crops made it easier to control weeds, but over time, glyphosate isn’t working as well anymore.
- Researchers wanted to see how effective glyphosate is alone compared to when it’s used with another herbicide first.
- They found that using glyphosate alone led to less consistent results, while combining it with another herbicide helped maintain effectiveness over time.
Glyphosate is an important herbicide worldwide, but its efficacy has been compromised where weed species have evolved glyphosate resistance. To better understand evolutionary outcomes of continued and strong selection from glyphosate exposure, we characterized variation in resistance in self-pollinating Conyza canadensis (horseweed) in Ohio and Iowa, where glyphosate resistance was first reported in 2002 and 2011, respectively. In 2015, we collected seeds from a total of 74 maternal plants (biotypes) from no-till soybean fields vs.
