Almost overnight, genetically engineered (GE) crops have profoundly changed agriculture in the U.S. Leading the way have been corn, soybean, and cotton crops resistant to the herbicide glyphosate. As a result, traditional farming and IPM methods havebeen tossed aside and replaced with a simplistic solution. Seeds are drilled into the soil without cultivation. When weeds appear, fields and crops are sprayed with glyphosate, usually by aerial application. Repeated applications are needed, and glyphosate resistant (GR) crops are often grown in the same field, -year after year (Duke and Powles 2009; Mortensen et al. 2012).
