"I have come to the conclusion that genetically-modified corn from the MON 810 strain constitutes a danger to the environment," Aigner told reporters in Berlin.
Germany's move, which has immediate effect, goes against the European Commission's decision to support the lifting of bans on planting MON 810 which have been imposed by governments in France, Austria, Hungary, Greece and Luxembourg.
In the UK, the Welsh Assembly has declared the country GM-free. Supported by Britain, Finland, the Netherlands and Sweden, the Commission argued last month that moves to outlaw the corn on the grounds that it is dangerous were unjust because it has been deemed safe by scientists at the European Food Safety Authority.
MON 810 was first approved for commercial use in the EU in 1998 and has been permitted as a commercial crop in Germany since 2005. More than 70 per cent of German consumers support a ban on GM crops for food.
The US biotechnology firm Monsanto which markets the maize did not return calls but industry observers said the ban by Europe's largest country with a strong agricultural lobby, was a blow to the company.
MON 810 was developed to resist a moth larva which bores into the stem of the corn and against which there is only one approved insecticide.
Monsanto has repeatedly argued that MON 810 crops are safe and has tried to encourage their use as a cheap and plentiful food. They are widely grown in the US, Latin America and China.
But opponents insist that too little is known about GM crops and their long-term genetic impact on wildlife and the food-chain.
The German ban will now be analysed by the Commission, amid fears it could trigger trade tensions with the US. Under World Trade Organisation rules, the US administration has the right to retaliate.
Nathalie Charbonneau a spokeswoman for the Commission said it would scrutinise the German decision and "decide on the most appropriate follow-up".
Lobbyists for the biotechnology industry in Germany described the decision as a setback for science and for the economy. They warned that it would prompt biotechnology companies to relocate to other parts of the world.
