As a follow-up to my last blog on counterfeit pesticides, I suspect that counterfeits contain insecticides that have been banned, like DDT which is non-biodegradable and can wind up in the drinking water, endanger wildlife, and other serious threats. DDT was once touted as a miracle insecticide that was good for farms and the general population. Spraying was widespread, until the book Silent Spring, written by Rachel Carson in 1962, exposed the dangers of DDT. Check out the Youtube video.
