"U.S. farmers are using more hazardous pesticides to fight weeds and insects due largely to heavy adoption of genetically modified crop technologies that are sparking a rise of 'superweeds' and hard-to-kill insects, according to a newly released study."
"Genetically engineered crops have led to an increase in overall pesticide use, by 404 million pounds from the time they were introduced in 1996 through 2011, according to the report by Charles Benbrook, a research professor at the Center for Sustaining Agriculture and Natural Resources at Washington State University.
Of that total, herbicide use increased over the 16-year period by 527 million pounds while insecticide use decreased by 123 million pounds."
