How GMOs Unleashed a Pesticide Gusher
—By Tom Philpott
For years, proponents of genetically modified crops have hailed them as a critical tool for weaning farmers from reliance on toxic pesticides. On its website, the GMO-seed-and-agrichemical giant Monsanto makes the green case for its Roundup Ready crops, engineered to withstand the company's own blockbuster herbicide, Roundup:
Roundup agricultural herbicides and other products are used to sustainably an [sic] effectively control weeds on the farm. Their use on Roundup Ready crops has allowed farmers to conserve fuel, reduce tillage and decrease the overall use of herbicides. [Emphasis added.]
But in a just-released paper published in the peer-reviewed Environmental Sciences Europe, Chuck Benbrook, research professor at Washington State University's Center for Sustaining Agriculture and Natural Resources, shreds that claim. He found that Monsanto's Roundup Ready technology, which dominates corn, soy, and cotton farming, has called forth a veritable monsoon of herbicides, both in terms of higher application rates for Roundup, and, in recent years, growing use of other, more-toxic herbicides.
