That article addresses pesticides inserted into plant DNA. That's for insect resistance. Roundup is an herbicide, not a pesticide. The post that I was referencing says this: "Since I read several articles about how Roundup is now in genetically modified seed corn, I buy only organic corn products, such as in cereal, canned corn or chips."
Unfortunately with the low price of grain and the high cost of fuel and fertilizer (natural or otherwise) large and medium scale farmers can't break even without using chemicals. You can only use mechanical methods to get rid of weeds in the first few weeks of crop growth and even at that point, weeds can quickly overtake a field and lower yields enough to cause loss of income. Crop insurance doesn't help either. Seed that isn't pest resistant can be ruined before it even breaks ground and there's no good cost-effective way to avoid pests coming into a 5000 acre field.
