The U.S. Department of Agriculture (USDA) and Environmental Protection Agency (EPA) herbicide data analyzed in the report, Superweeds: How Biotech Crops Bolster the Pesticide Industry, shows that herbicide use on corn, cotton and soybeans has steadily grown by 26 percent in the years between 2001 and 2010. The widely used glyphosate herbicides, primarily Monsanto’s Roundup Ready line, have become ineffective as the weeds develop stronger resistance due to continuous over-exposure to the chemical. As glyphosate proves to be increasingly ineffective, more farmers are turning to more dangerous herbicides including 2,4-D [aka: Agent Orange]. Use of 2,4-D has increased since glyphosate-resistant crops became widespread, growing 90 percent between 2000 and 2012.
