In 2009 Swiss biotech giant Syngenta made a bold prediction that by 2013 a quarter of U.S. cropland would be infested with glyphosate-resistant superweeds. I heartily congratulate Syngenta for its foresight, if not the response to it. By January 2013, 61.2 million acres of U.S. farmland suffered from an increasingly stubborn case of superweeds. So Syngenta was being uncharacteristically modest – around one third of the 185 million acres of U.S. land planted with corn, cotton and soy has weeds that can’t be killed by normal means, adding significantly to the cost and effort of farming.
As 2013 drew to a close, a new Union of Concerned Scientists (UCS) policy brief reported that, in fact, “Almost 50 percent of surveyed farms are infested with glyphosate-resistant weeds, and the rate of these weeds’ spread has been increasing.” UCS added:
“Herbicide-resistant weeds are also symptomatic of a bigger problem: an out-dated system of farming that relies on planting huge acreages of the same crop year after year. This system, called monoculture, has provided especially good habitat for weeds and pests and accelerated the development of resistance. In response, Monsanto and its competitors are now proposing to throw more herbicides at resistant weeds, an approach that ignores the underlying biology of agricultural systems and will inevitably lead to more resistance and a further spiraling up of herbicide use.”
The rapid spike in the use of Monsanto’s best-selling weed killer glyphosate in the U.S. is closely linked to the uptake of genetically modified (GM) crops designed to be used with the brand name version of the chemical (Roundup). As widely predicted by both industry and GM skeptics, problematic weeds like Palmer amaranth quickly developed resistance to Roundup and are spreading fast as farmers struggle to kill them with combinations of chemicals in heavier concentrations, or simply resorting to hand weeding hundreds of acres of fields. The problem is so serious in the Southern U.S. that UCS reports, “92 percent of cotton and soybean fields are infested as a result of Roundup Ready crops.” Superweeds are also causing escalating problems in other countries with heavy GM crop use, including in the soy fields of Argentina and Brazil upon which the EU is so reliant to fuel its factory farms.
