Bayer could integrate the assets of Monsanto into its own crop science division and drop the controversial company's name altogether, according to media reports in the US.
Bayer recently announced the US$66 billion acquisition of the world's largest seeds and crop chemicals company. Monsanto is also known for its disputes with environmental groups over genetically-modified crops.
The deal faces significant anti-trust hurdles and is not expected to be completed before late 2017, according to Bloomberg.
Analysts have said Bayer's reputation - it was recognised as the world's most reputable pharmaceutical brand by the Reputation Institute - could help address many of the issues Monsanto has faced.
Bayer CEO Werner Baumann recently told investors the acquisition was an opportunity for the companies to jointly “get beyond this image and reputation thing” by building on the trust Bayer enjoys in Europe.
