German chemicals and pharmaceuticals giant Bayer will discard the name Monsanto when it takes over the controversial US seeds and pesticides producer this week, it said Monday.

But Bayer executives insisted Monsanto practices rejected by many environmentalists, including genetic modification of seeds and deployment of “crop protection” technologies like pesticides, were vital to help feed a growing world population.

“The company name is and will remain Bayer. Monsanto will no longer be a company name,” chief executive Werner Baumann told journalists during a telephone conference.

Bayer’s $63 billion (54 billion euro) buyout of Monsanto — one of the largest in German corporate history — is set to close Thursday, birthing a global giant with 115,000 employees and revenues of some 45 billion euros.

Bosses plan to name the merged agrichemical division Bayer Crop Science once the merger is complete, German business newspaper Handelsblatt reported, citing “industry sources”.
