MON810 maize is a product of the Monsanto company. The maize line has been genetically modified to be resistant against lepidopteran insects.
In 2009, MON810 maize was commercially grown in 17 countries, including six countries of the EU. Additionally, MON810 was imported in several other countries.
MON810 maize was produced by particle bombardment and contains a truncated cry1Ab gene which confers resistance against European stemborer and other lepidoptera.
The cultivation of MON810 is currently banned in Austria, Hungary, France, Greece, Germany, and Luxembourg
The event MON810 produces a Bt toxin against lepidoptera (European stemborer and other moths/butterflies); MON88017 is a stacked event with glyphosate herbicide tolerance and a Bt toxin against coleptera (corn root worm and other beetles).
As an F1 hybrid of two deregulated GMOs it is not regulated in the US. MON88017 x MON810 has environmental, food and feed approvals in a number of countries, mainly in Asia and in Mexico.
