Hey, GM Crops Are Great — If You Like Superweeds, That IsThe gospel of high-tech genetically modified (GM) crops is not sounding quite so sweet in the land of the converted. A new pest, the evil pigweed, is hitting headlines and chomping its way across Sun Belt states, threatening to transform cotton and soybean plots into weed battlefields.
In late 2004, “superweeds” that resisted Monsanto’s iconic “Roundup” herbicide, popped up in GM crops in the county of Macon, Georgia. Monsanto, the US multinational biotech corporation, is the world’s leading producer of Roundup, as well as genetically engineered seeds. Company figures show that nine out of 10 US farmers produce Roundup Ready seeds for their soybean crops.
Superweeds have since alarmingly appeared in other parts of Georgia, as well as South Carolina, North Carolina, Arkansas, Tennessee, Kentucky and Missouri, according to media reports. Roundup contains the active ingredient glyphosate, which is the most used herbicide in the USA.

In 2007, 10,000 acres of land were abandoned in Macon country, the epicentre of the superweed explosion, North Carolina State University’s Alan York told local media.
The perfect weed
Had Monsanto wanted to design a deadlier weed, they probably could not have done better. Resistant pigweed is the most feared superweed, alongside horseweed, ragweed and waterhemp.

Indeed, according to Monsanto press releases, company sales representatives are encouraging farmers to mix glyphosate and older herbicides such as 2,4-D, a herbicide which was banned in Sweden, Denmark and Norway over its links to cancer, reproductive harm and mental impairment. 2,4-D is also well-known for being a component of Agent Orange, a toxic herbicide which was used in chemical warfare in Vietnam in the 1960s.
