Soybeans are the most heavily pesticide sprayed food crop so perhaps he was referring to that.

“Soybeans are the most heavily pesticide sprayed food crop so perhaps he was referring to that.”
I have been growing soybeans for a few decades. In some years, roundup is all that I ever use. In others, I have used a bit of residual herbicide, but never an insecticide.
Fruits and vegetables have far more herbicides, insecticides, and fungicides than any cereal grain. And, for the record, golf courses use more pesticides/acre than any ag application on the planet.
