Explanation:

For decades, conventional farmers have been trapped on a “pesticide treadmill.” When persistent organochlorine pesticides like DDT were phased out for their health and environmental harms, a new fast-acting generation of organophosphates were phased in. And the pattern continues.
With the introduction of genetically engineered (GE) crops, the pesticide treadmill has shifted into high gear.
Patented GE seeds are designed for use with specific pesticides, leading to increased use of these chemicals. And widespread application of these pesticides leads to the emergence of herbicide-resistant “superweeds,” among other things.
