Study summarizes trends in glyphosate use

PesticideThe rising use of glyphosate, particularly with genetically engineered crops, has triggered the spread of tolerant and resistant weeds in the United States and globally, researcher Charles Benbrook points out in a paper in the latest edition of Environmental Sciences Europe. Outlining the trends in glyphosate usage, Benbrook recommends that the findings be used to help researchers understand and quantify the risks and benefits related to that usage. “The frequency and levels of glyphosate and residues in a variety of foods are increasing, and more refined dietary risk assessments should be carried out,” Benbrook writes, noting a WHO agency classified glyphosate as probably carcinogenic to humans in 2015.
