Pesticide Use Rises as Herbicide-resistant Weeds Undermine Performance of Major GE Crops, New WSU Study Shows

Door Brian Clark, Washington State University, 1 oktober 2012

A study published this week by Washington State University research professor Charles Benbrook finds that the use of herbicides in the production of three genetically modified herbicide-tolerant crops — cotton, soybeans and corn — has actually increased. This counterintuitive finding is based on an exhaustive analysis of publicly available data from the U.S. Department of Agriculture’s National Agriculture Statistics Service. Benbrook’s analysis is the first peer-reviewed, published estimate of the impacts of genetically engineered (GE) herbicide-resistant (HT) crops on pesticide use.

[...] “Resistant weeds have become a major problem for many farmers reliant on GE crops, and are now driving up the volume of herbicide needed each year by about 25 percent,” Benbrook said.

"Farmers in the US are already struggling, as they try to spray their way out of the corner they’re backed into. The reliance on herbicide-tolerant crops in the US has triggered the emergence and rapid spread of nearly two dozen glyphosate-resistant weeds, driving up farm production costs, as well as the volume and ecotoxicity of herbicides needed to prevent major yield loss," according to Dr. Benbrook.
