About Bayer AG

In order to separate operational and strategic management Bayer AG was reorganized into a holding company in December 2003. The groups core businesses were transformed into limited companies, each controlled by Bayer AG. These companies are: Bayer CropScience AG; Bayer HealthCare AG; Bayer Material Science AG and Bayer Chemicals AG.

Bayer AG shares are listed on XETRA in Germany, LSE in the United Kingdom and on NYSE in the United States.


Bayer became part of IG Farben, a conglomerate of German chemical industries that emerged during World War I. When the Allies split IG Farben after World War II for involvement in several war crimes, Bayer reappeared as an individual business.

They have discovered, among others:

Bayer Cropscience

In 2002 Bayer AG acquired
Aventis CropScience and formed Bayer CropScience. In addition to conventional agrochemical business it is involved in genetic engineering of food.

Pesticide harm to bees

Bayer AG is involved in an ongoing controversy with French and Nova Scotian beekeepers over claimed pesticide kills of honeybees from its seed treatment insecticide Gaucho. France has since issued a provisional ban on the use of Gaucho for corn seed treatment pending further action. A consortium of U.S. beekeepers has also filed a civil suit against Bayer CropScience for alleged losses.
