You have got to be kidding. So a man can't use all his land to plant crops because of something someone else does?
I find that both hard to believe and anti-American.
No, that is not what I am saying at all. You cannot stop nature, corn produces way more pollen then it uses and it will get airborne. If you raise a specialty corn crop like seed corn, non GMO, White corn for tortilla chips, ect. You plant a border to keep contaminate pollen out. It is common sense, buyers of these products demand and expect it.
This border is not wasted, it is usually harvested separate and sold as regular field corn. These practices have been done long before GMO was ever even a thought.
