Use of herbicides such as Monsanto’s Roundup is on the rise. As weeds become resistant, environmental activists blame genetically modified crops
by Brian Hindo
It’s been 12 years since the first genetically modified crop was sown in the U.S., and controversy has raged since. Now, another salvo has been launched, in the form of a new report from environmental activist organization Friends of the Earth International and the Center for Food Safety, a Washington (D.C.) advocacy group. Called Who Benefits from GM Crops?, the study examines the emergence of "superweeds" that have developed a resistance to conventional herbicides such as Monsanto’s (MON) Roundup. The culprits, says the report, are plants like corn, soybeans, and cotton that have been genetically modified to survive Roundup. Farmers can spray their fields and the weeds will die but the crops will thrive.
As more acres of "Roundup Ready" crops are planted, the use of the pesticide has increased. The increased application has led some weeds to develop a resistance to glyphosate, the generic term for the chemical in Roundup. And, in turn, farmers have had to apply stronger doses of pesticide to kill the superweeds.
