Herbicide-resistant superweeds threaten to overgrow U.S. fields, so agriculture companies have genetically engineered a new generation of plants to withstand heavy doses of multiple, extra-toxic weed-killing chemicals...Next-generation biotech crops erupted into controversy with the U.S. Department of Agriculture’s ongoing review of Enlist, a Dow-manufactured corn variety endowed with genes that let it tolerate high doses of both glyphosate, an industry-standard herbicide better known as Roundup, and a decades-old herbicide called 2,4-D...Roundup Ready varieties now account for 90 percent of U.S. soybeans and 70 percent of corn and cotton, and the pipeline for new herbicidal chemicals is mostly empty.
