Back in the 1990s, Monsanto cashed in on the accidental discovery that it was possible to genetically engineer certain crop plants so that they were resistant to the Monsanto weedkiller, Roundup. The seed for these crops, mainly soy, canola, corn, and cotton, was marketed by Monsanto as “Roundup Ready”
Roundup was the weedkiller of choice for a whole variety of reasons in any case. It killed a broad spectrum of weeds, was easy and safe to work with, and broke down quickly, reducing its environmental impact (which is not to say that it had zero impact!!)
Up till then, you couldn’t use it once your crops had been planted. You needed other, more expensive and labour intensive weed control methods. Now, you could plant your cash crop, and spray the whole paddock with Roundup as much as you wanted to clear the weeds, with no harm to your cash crop!
And so began the US love affair with Roundup and genetically engineered food. Monsanto made a killing with Roundup and it also made a killing with its genetically engineered Roundup Ready seeds, which had to be bought new each year, not saved from last year’s crop.
