Thanks to Bayer and Shell, good luck finding untainted samples...
So your knee-jerk response is to blame flawed science on "BIG EVIL KORPARASHUNS!!!!"
Tell us, what color is the sky on your world?
No, I'm well aware of how agribusiness works, and how commissioned salesmen actually do a lot of work to sell as much product as possible. Much of my extended family is in farming, either as farmers, or as those who sell products or services to farmers.
Farmers want the best yields possible. They assume that the products advertised to them are acceptable, and they use those products widely if they seem to solve the ill that the farmer was fighting against. As such, it's very likely that Bayer and Shell have managed to sell this product to loads and loads of farmers.
