GMOs are a ploy by agrichemical corporations to sell more pesticides/herbicides.

Some GMO crops—such as Roundup Ready—can tolerate applications of herbicides, a trait that reduces the need for hand weeding or mechanical cultivation, which disturbs the soil. People sometimes imagine that GMOs use more insecticides, but the reverse is true with GMO crops that are bred with a natural form of insect-resistance, thus minimizing or eliminating the need to spray pesticides for crop protection. Overall, scientists say GMOs have reduced the use of chemical pesticides—both herbicides and insecticides—by 37%. (Qaim et al. 2014).
