As has been said: absolutely untrue. Insecticides kill bugs. Fungicides kill fungi. Herbicides kill plants (including, very often, desired plants.) All of them are pesticides.

What do you think happens to the plant at harvest? Do you think all bits of it, roots and all, are removed from the environment? If you do think that: it isn't true.

Again, that only works if you ignore the production of pesticide by the corn itself.

Yields per acre have been going up over the past century or more for a whole lot of reasons. Nutrition per acre may be a separate issue. And any increase in yield due to the specific common GMO traits is short lived, as the massive reliance on those specific GMO traits leads to resistance in the insects and weeds affected.
