Impacts of Genetically Engineered Crops on Pesticide Use: The First 
Thirteen Years

This report from the U.S.-based Organic Center finds that herbicide 
use in the U.S. has increased because of the planting of genetically 
modified (GM) herbicide tolerant soy, corn, and cotton varieties. GM 
crops have been responsible for an increase of 383 million pounds of 
herbicide use in the U.S. over the first 13 years of commercial use 
of GM crops (1996-2008), the report states. The report finds, in 
addition, that herbicide use has increased as farmers, especially in 
the U.S. South, have attempted to combat glyphosate-tolerant weeds by 
applying more herbicides. The report "draws principally" on data from 
the U.S. Department of Agriculture (USDA). The author of the report, 
Charles Benbrook, is chief scientist at the Organic Center. The 
69-page report is available online at the link below.
