Chemical Arms Race in America Agent Orange Corn Next
B. McPherson There’s an arms race going on in N. America’s cornfields. The race is developing genetically modified crops to resist ever more lavish spraying of herbicides. An early winner in the weed race was Monsanto, a corporation that developed seeds containing weed genes that could resist the spraying of that other Monsanto product, Roundup. Roundup was an effective weed/plant killer for many years, but gradually as Nature will do, some weeds survived Roundup to reproduce. So farmers sprayed Roundup(or the generic glyphosate) in ever heavier doses. The effect has been to breed a wide number of SuperWeeds that will not die when sprayed with the herbicide. Now rival Agro company Dow AgroSciences has developed a GM corn that carries a gene resistant to Dow Chemical’s herbicide 2,4-D. It is seeking to be allowed to start widespread planting of the genetically altered seeds in time for the 2013 crop year. Fields planted with the new corn, dubbed Enlist, could be ...
