Mexico will ban glyphosate and transgenic corn by 2024. U.S. Agriculture Secretary Tom Vilsack has been "assured" by his Mexican counterpart that the ban won't hurt U.S. corn exports,

Mexican President Andrés Manuel López Obrador wants to expand maize output on small farms. U.S. farmers and Mexico's impoverished will lose.
Farmers use glyphosate (brand name Roundup) to eradicate weeds before sowing animal feed maize and to expedite the harvest of certain grain and other crops. If you're a homeowner,
it's probably in lawn and gardening items. The EPA concluded "no health hazards when glyphosate is used as directed."
Humans have cross-pollinated plants for millennia. Agronomist Norman Borlaug invented "dwarf wheat" in the mid-20th century.
