"Like the popular Roundup Ready system developed by rival Monsanto Co., farmers who plant Enlist crops can spray their fields with Enlist herbicide and kill weeds but not the crops," Gillam writes. Roundup Ready—used on about 90 percent of U.S. corn and soybean plantings every spring—has wiped out milkweed plants in Midwestern corn and soybean fields and has been blamed for decreasing the nation's number of monarch butterflies.
