Genetically engineered crops benefit many farmers, but the technology needs proper management to remain effective

Many U.S. farmers who grow genetically engineered (GE) crops are realizing substantial economic and environmental benefits -- such as lower production costs, fewer pest problems, reduced use of pesticides, and better yields -- compared with conventional crops, says a new report from the National Research Council. However, GE crops resistant to the herbicide glyphosate -- a main component in Roundup and other commercial weed killers -- could develop more weed problems as weeds evolve their own resistance to glyphosate. GE crops could lose their effectiveness unless farmers also use other proven weed and insect management practices.
